62,672,746 | I've updated my .NET core 3.1+Angular 9.1 to Angular 10.0.2,
steps I used:
1. update Vs TypeScript to [3.9.5](https://marketplace.visualstudio.com/items?itemName=TypeScriptTeam.typescript-395)
2. run `ng update @angular/core @angular/cli`
After that VS 2019 v 16.6.3 shows no intellisense and validation,project runs without problems.
If I open the project in VS Code all work fine
I've found the problem is just after I run `ng update @angular/cli`
reverting project to 9.1 all works fine

] | I experienced the same issue after upgrading a project to Angular 10. It appears to be an issue with the latest version of Visual Studio 2019 not handling the changes to the tsconfig.json file and the introduction tsconfig.base.json.
As a workaround until this is resolved in VS 2019 I copied the contents of tsconfig.base.json up to tsconfig.json and commented out the upgraded config.

Until the fix is available to the public, following changes in `tsconfig.json` resolve the issue for me.
```
{
"extends": "./tsconfig.base.json"
}
``` | I had the exact same problem after I migrated from Angular 9 to Angular 10.
I found the following worked for me:
**TL;DR**
=========
In all the 'project' level tsconfig files (tsconfig.app.json, tsconfig.spec.json, tsconfig.e2e.json) just change the 'extends' property from:
```
{
"extends": "../tsconfig.json"
...
}
```
To the following:
```
{
"extends": "../tsconfig.base.json"
...
}
```
**Full Version**
================
Before running `ng update` I had the following structure:
```
ClientApp
|_ tsconfig.json
|_ src
|_ tsconfig.app.json
|_ tsconfig.spec.json
|_ e2e
|_ tsconfig.e2e.json
```
After running `ng update` I had the following structure:
```
ClientApp
|_ tsconfig.json
|_ tsconfig.base.json
|_ src
|_ tsconfig.app.json
|_ tsconfig.spec.json
|_ e2e
|_ tsconfig.e2e.json
```
After reading the Angular migration notes I noticed my version of `tsconfig.json` and `tsconfig.base.json` were identical. This still worked but it didn't match what Angular were describing in the notes. So I decided to change my `tsconfig.json. manually to the following:
```
{
"files": [],
"references": [
{
"path": "./src/tsconfig.app.json"
},
{
"path": "./src/tsconfig.spec.json"
},
{
"path": "./e2e/tsconfig.e2e.json"
}
]
}
```
And like everyone else it broke my app.
So I had a look at the 'project' level tsconfig files and noticed the 'extends' property was still point to `tsconfig.json` and not to `tsconfig.base.json`. After updating my 'project' level tsconfig files to pointing to the `tsconfig.base.json` file everything just worked.
Happy days!
:-)
I am guessing the `ng update` should "automagically" find and update all the 'project' level tsconfig files but it looks like it doesn't. The fix however is fairly straight forward though.

Update
======
Although changing extends property did resolve my compilation issues. When I closed and reopened Visual Studio the next day the IntelliSense started to fail.
Only by making the `tsconfig.json` to be the same as the `tsconfig.base.json` could I get both the compilation and IntelliSense working. |
62,672,754 | When I checked the document in the email, I was able to select the Signature design registered in the sand box account. But there is no Signature information in embedded app, so how can I get it?

So I had a look at the 'project' level tsconfig files and noticed the 'extends' property was still point to `tsconfig.json` and not to `tsconfig.base.json`. After updating my 'project' level tsconfig files to pointing to the `tsconfig.base.json` file everything just worked.
Happy days!
:-)
I am guessing the `ng update` should "automagically" find and update all the 'project' level tsconfig files but it looks like it doesn't. The fix however is fairly straight forward though.
---
Update
======
Although changing extends property did resolve my compilation issues. When I closed and reopened Visual Studio the next day the IntelliSense started to fail.
Only by making the `tsconfig.json` to be the same as the `tsconfig.base.json` could I get both the compilation and IntelliSense working. |
62,672,772 | I'm having troubles figuring how to make a circle doodle(like a hand drawn sketch) appear on a link when hovered. In a perfect world it should be an animated svg path, but at this point just to appear works for me. Here is what exactly I'm trying to achieve:
[](https://i.stack.imgur.com/OH1Sz.jpg)
I've tried with background-image set to opacity:0 and when hover on opacity:1, but the issue is that when the link is longer the background image doesn't cover it all. Also I've tried with borders, but then I can't add a custom border shape, to look like a circle sketch you do with a pen.
Here is an example I found online: [click here](https://elementor.com/blog/introducing-animated-headline/) , the "Circle Me" example, under "Highlighted headlines"
I hope that this all makes sense,

62,672,775 | I got this number `1.12412` and I want to `round it to 1.12415` or `1.12410 (muliple of 5 in last decimal)`
If using the `Round(X,4)` function I get `1.1241 (4 decimals)`.
Is there a function that can make that happen?

```
import numpy as np
rounding_unit = 0.00005
np.round(1.12412/rounding_unit) * rounding_unit

1. Multiply your number by 2
2. Use `Round(X,4)`
3. Divide the result by 2

Can you tell me how to properly execute my Maven project through Docker? I did not find any information to solve this problem by myself.

Edit
----
Indeed I have already tried with && but I have the impression that because of this, it is the host who executes the command and not the container. Something like this is happening :
```sh
$ docker run -it --rm --name my-maven-project -v /var/www/html/Recommandation/:/usr/src/mymaven -p 88:88 -w /usr/src/mymaven maven:latest mvn clean install
$ java target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App
```
`Error: unable to find or load main class target.Recommandation-1.0-SNAPSHOT.jar`
This is the same problem with `;`
I also tried this : `docker run -it --rm --name my-maven-project -v /var/www/html/Recommandation/:/usr/src/mymaven -p 88:88 -w /usr/src/mymaven maven:latest bash -c "mvn clean install && java target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App"`

The way you pass your commands to docker is just a little bit wrong.
Basically your try to execute this command inside your container:
```
mvn clean install java target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App
```
If you try to execute this on your Host you will receive the same error as in your container.
You want to execute two separate commands in your container:
1. build your project
2. execute the Jar
To achieve this you have to chain both commands.
Because you only want to execute your JAR-File if the build was successful you have to use the `&&` Operator.
```
mvn clean install && java target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App
```
For more details have a look at this Post here:
[10 Useful Chaining Operators in Linux with Practical Examples](https://www.tecmint.com/chaining-operators-in-linux-with-practical-examples/)
BTW. You don't need to execute the `install` goal. `package` should be sufficient.
---
Edit
----
As you can now see in your output the project was compiled successfully but your JAR-File could not be executed. This is because you are missing the `-jar` parameter. (I also didn't noticed this in my original answer.)
Therefore you should execute the following command:
```
mvn clean install && java -jar target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App
```

Regarding your comment
>

You are completely right - that was kind of misleading explanation by me.
If you want to pass this to the `docker run` command you have to do the following:
```
docker run [your_parameters] maven:latest /bin/bash -c "mvn clean install && java -jar target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App"
``` | Probably the issue is with command
```
docker run -it --rm --name my-maven-project -v /var/www/html/Recommandation/:/usr/src/mymaven -p 88:88 -w /usr/src/mymaven maven:latest mvn clean install java target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App
```
Maven thinks it should execute `clean` `install` and than `java` (which is not known to maven)
Try separating with `;`
```
docker run -it --rm --name my-maven-project -v /var/www/html/Recommandation/:/usr/src/mymaven -p 88:88 -w /usr/src/mymaven maven:latest mvn clean install; java target/Recommandation-1.0-SNAPSHOT.jar org.exemple.demo.App
```
Now if you want to run both commands in Docker, probably better would be wrapping this in a simple bash script and executing from the docker entry point. |

] | You can use the `controller`.
So, your code should be like:
1st, initialize `TextEditingController` variable somewhere inside the top of your class:
```
final myController = TextEditingController();
```
And then put that controller inside each `TextFormField`. (Note: I only see your first `TextFormField` in the code you provided. So, I only put it once. Make sure to put it on each `TexFormField`)

return null;
},
onSaved: (value) {
_displayName = value;
},
decoration: _textFormFieldDecoration(
hintText: 'your display name',
padding: 12.0,

),
```
And then, inside the button, call that controller:
```
RaisedButton(

child: Text('Cancel', style: TextStyle(color: Colors.white, fontSize: 16)),
onPressed: () {
setState(() {
myController.clear();
});
},

```

2. Pass your controller to the text field `controller: _nameController,`

62,672,913 | This is my first question here and I'm beginner in coding so forgive me if my question is not very clear.
I have stored wages in Room database column called "wage" and the datatype is double. There is wages from different days and I would like to show total from those double numbers in my Activity. If tried many different ways to do it, but I just can't get it to work without different errors.
It would be ideal if I could store that sum total into a variable so I can use it easily and probably subtract some value from it if necessary.
I use Repository and ViewModel to access my database and RecyclerView, Adapter and CardView to show different data in my MainActivity. I hope I don't need to use these to access this sum-number but get as direct access to it as possible.
This is my @entity
```
@Entity (tableName = "shift_table")
public class Shift implements Serializable {
@PrimaryKey(autoGenerate = true)
private int id;
@ColumnInfo(name = "date")
private String date;
@ColumnInfo(name = "start")
private String start;
@ColumnInfo(name = "end")
private String end;
@ColumnInfo (name = "hours")
private String hours;
@ColumnInfo (name = "wage")
private double wage;
public Shift(String date, String start, String end, String hours, double wage) {
this.date = date;
this.start = start;
this.end = end;
this.hours = hours;
this.wage = wage;
}
public void setId(int id) {
this.id = id;
}
public int getId() {
return id;
}
public String getDate() {
return date;
}
public String getStart() {
return start;
}
public String getEnd() {
return end;
}
public String getHours() {
return hours;
}
public double getWage() {
return wage;
}
}
```
This is my @Dao
```
@Dao
public interface ShiftDao {
@Insert
void insert (Shift shift);
@Update
void update (Shift shift);
@Delete
void delete (Shift shift);
@Query("DELETE FROM shift_table")
void deleteAllShifts();
@Query("SELECT * FROM shift_table ORDER BY id DESC")
LiveData<List<Shift>> getAllShifts();
@Query("SELECT SUM(wage) FROM shift_table")
What here?
}
```
How I can get that SUM from wage-column to variable and show it in TextView? | 2020/07/01 | [
"https://Stackoverflow.com/questions/62672913",
"https://Stackoverflow.com",
"https://Stackoverflow.com/users/13845850/"
] | It should be something like this, in your DAO:
```
@Query("SELECT SUM(" + "wage" + ") as wagesSum "+ " FROM " + "shift_table")
double getWageSum();
```
Now, a few suggestions:
1. Put your column names into final constants, like this:
public final String COLUMN\_DATE\_NAME = "date";
@ColumnInfo(name = COLUMN\_DATE\_NAME)
private String date;
This way, it will be easier for you to access the constants statically in DAO, and if in the future you might want to change the name of that column, you would change it only in the constant. Also, please do the same for the table name. These constants will help you when you write possible future migrations as well.
Happy coding! | here is some of my kotlin code, enjoy :)
DAO
```
@Query("SELECT SUM(column) FROM table")
fun getSum(): Int
```
Repository
```
private val mDao: Dao
init {
val database = getInstance(mApplication)
mDao = database.dao()
}
private class sumAsyncTask(private val mDao: Dao) : AsyncTask<Void, Void, Int>() {
protected override fun doInBackground(vararg voids: Void): Int {
return mDao.getSum()
}
}
fun getSum(): Int {
return sumAsyncTask(mDao).execute().get()
}

There might be other ways to do this async, this is what i use.
PS: as for the Doubles, you might want to store them as Long / SQL Integer instead (see [Create Room Entity for a Table which has a field with LONG datatype in Sqlite](https://stackoverflow.com/questions/54035138/create-room-entity-for-a-table-which-has-a-field-with-long-datatype-in-sqlite/54049286))
This can be done by simply multiplying by 100 (then you have cents if your wages represent money) before storing in the database |
62,672,913 | This is my first question here and I'm beginner in coding so forgive me if my question is not very clear.
I have stored wages in Room database column called "wage" and the datatype is double. There is wages from different days and I would like to show total from those double numbers in my Activity. If tried many different ways to do it, but I just can't get it to work without different errors.
It would be ideal if I could store that sum total into a variable so I can use it easily and probably subtract some value from it if necessary.
I use Repository and ViewModel to access my database and RecyclerView, Adapter and CardView to show different data in my MainActivity. I hope I don't need to use these to access this sum-number but get as direct access to it as possible.
This is my @entity
```
@Entity (tableName = "shift_table")
public class Shift implements Serializable {
@PrimaryKey(autoGenerate = true)
private int id;
@ColumnInfo(name = "date")
private String date;
@ColumnInfo(name = "start")
private String start;
@ColumnInfo(name = "end")
private String end;
@ColumnInfo (name = "hours")
private String hours;
@ColumnInfo (name = "wage")
private double wage;
public Shift(String date, String start, String end, String hours, double wage) {
this.date = date;
this.start = start;
this.end = end;
this.hours = hours;
this.wage = wage;
}
public void setId(int id) {
this.id = id;
}
public int getId() {
return id;
}
public String getDate() {
return date;
}
public String getStart() {
return start;
}
public String getEnd() {
return end;
}
public String getHours() {
return hours;
}
public double getWage() {
return wage;
}
}
```
This is my @Dao
```
@Dao
public interface ShiftDao {
@Insert
void insert (Shift shift);
@Update
void update (Shift shift);
@Delete
void delete (Shift shift);
@Query("DELETE FROM shift_table")
void deleteAllShifts();
@Query("SELECT * FROM shift_table ORDER BY id DESC")
LiveData<List<Shift>> getAllShifts();
@Query("SELECT SUM(wage) FROM shift_table")
What here?
}
```
How I can get that SUM from wage-column to variable and show it in TextView? | 2020/07/01 | [

] | It should be something like this, in your DAO:
```
@Query("SELECT SUM(" + "wage" + ") as wagesSum "+ " FROM " + "shift_table")
double getWageSum();
```
Now, a few suggestions:
1. Put your column names into final constants, like this:
public final String COLUMN\_DATE\_NAME = "date";
@ColumnInfo(name = COLUMN\_DATE\_NAME)
private String date;
This way, it will be easier for you to access the constants statically in DAO, and if in the future you might want to change the name of that column, you would change it only in the constant. Also, please do the same for the table name. These constants will help you when you write possible future migrations as well.
Happy coding! | You can get sum of double column like below example. Sum of double column value will be store in `BigDecimal`. For more details you can check [documentation](https://developer.android.com/topic/libraries/architecture/livedata#extend_livedata).

62,672,947 | I'm following a tutorial on Laravel, adding to a DB via a form. At the end of a function that saves to a DB, it returns back to the page where the form is, but I want to be taken to another page where the information is displayed. In the tutorial I created a controller with a function that returns a view containing all the database info - that element works fine however I can't seem to find a way of calling this function directly after saving to the database. I can also return any other view which just displays static view ( just html with no data handling ). Is what I'm trying to achieve possible?
```
public function store(){
$li = new \App\LTest1();
$li->creator = request('creator');
$li->title = request('title');
$li->views = request('views');
$li->save();

62,672,947 | I'm following a tutorial on Laravel, adding to a DB via a form. At the end of a function that saves to a DB, it returns back to the page where the form is, but I want to be taken to another page where the information is displayed. In the tutorial I created a controller with a function that returns a view containing all the database info - that element works fine however I can't seem to find a way of calling this function directly after saving to the database. I can also return any other view which just displays static view ( just html with no data handling ). Is what I'm trying to achieve possible?
```
public function store(){
$li = new \App\LTest1();
$li->creator = request('creator');
$li->title = request('title');
$li->views = request('views');

for example if 'AT' is checked I also want to be able to check 'Herstart'.
so this condition only needs to happen when 'AT' is selected.
this is a picture of the console on how the radio buttons are build :

62,673,049 | I have a form in a modal (bootstrap4 theme for a wordpress site) in php. After a user submits the form in this modal, the page "reloads" and the "Form submitted successfully" message replaces the form. This means that when a user clicks the button to open the modal again, there is no form there; just a success message. How do I prevent this behaviour? I want to "reset" the form for a user to a clean form so they can submit again and again each time.

62,673,071 | I'm working on a website and came upon a strange problem with i18next that I can't seem to solve.
I want i18next to save the current language in a cookie but only when the user has accepted to store cookies (custom cookie banner component)
Currently, I have the following code:
### i18n.js
```
import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import Backend from 'i18next-xhr-backend';
import LanguageDetector from 'i18next-browser-languagedetector';
i18n
.use(Backend)
.use(LanguageDetector)
.use(initReactI18next)
.init({
whitelist: ['en', 'fr', 'nl'],
fallbackLng: 'en',
interpolation: {
escapeValue: false,
},
ns: [
'common',
],
react: {
wait: true,
},
detection: {
caches: ['cookie'],
lookupFromPathIndex: 0,
},
});
```
### index.js
```
import React, { Suspense } from 'react';
import ReactDOM from 'react-dom';
import './i18n';
...
```
My problem is with the `caches: ['cookie']` property. I want it to be include "cookie" but only after the user has clicked on an "I Agree" button somewhere on the website. Is there a way to first load the i18next with an empty caches array and reload the object when the user clicked on "I Agree".
On the next page visit (when the user accepted cookies) i18next should know it can read from the language cookie as well. But I think when I know how to fix the first issue I can solve this issue easily. | 2020/07/01 | [

First, make an API token for Kaggle. On Kaggle's website go to "My Account", Scroll to API section and click on "Create New API Token" - It will download kaggle.json file on your machine.
Then run the following in Google Colab:
```
from google.colab import files
files.upload() # Browse for the kaggle.json file that you downloaded
# Make directory named kaggle, copy kaggle.json file there, and change the permissions of the file.
! mkdir ~/.kaggle
! cp kaggle.json ~/.kaggle/
! chmod 600 ~/.kaggle/kaggle.json
# You can check if everything's okay by running this command.
! kaggle datasets list
# Download and unzip sign-language-mnist dataset into '/usr/local'
! kaggle datasets download -d datamunge/sign-language-mnist --path '/usr/local' --unzip

62,673,091 | I'm toying around with instance control flow and static control flow, notice the code below
```
class A {
{
m1();
}
A(){
System.out.println("A constructor");
}
void m1(){
System.out.println("A m1");
}
}
public class Main extends A {
public static void main(String[] args) throws Exception {
Main m = new Main();
}
void m1(){
System.out.println("Main m1");
}
}
```
The output for the code is:
Main m1
A constructor
I know this is because:
First, static blocks and variables were identified top-to-bottom parent-to-child, in this case there was just a `main()` that was static.
Second, the static blocks and variable assignments are executed, so `main()`'s execution starts, and there is an attempt to create a new `Main` object.
So third, the instance blocks and variables of parent class will be identified. Then they will be executed top-bottom. (After that the constructor of the parent class will run, then the instance blocks and variables of child class will be identified, following which they will be executed top-bottom and finally the child class' constructor will execute).
So the instance block inside A, calls `m1()`. Then, A's constructor executes. Finally, control flow is returned to `main()` and program terminates.
Now, the call to `m1()` from A invoked `m1()` of `Main`. However, had I made both the `m1()` methods static, everything else remaining same, the call to `m1()` from the instance block of A would then have invoked `m1()` of A.
I have two questions(Why? Purely for academic reasons, I'm still learning Java):
1. When both the `m1()` methods are non-static, is it possible to invoke A's m1() from the instance block of A? I tried doing a `this.m1()` but that still invoked Main's m1().(Why?)
2. When both the `m1()` methods are static, is it possible to invoke Main's m1() from the instance block of A? (I'm guessing no but I'm not certain).
I know in the first case, it's overriding taking place, and in the second case it's method hiding. But I'm still not sure how to answer my questions based on that knowledge. | 2020/07/01 | [

] | After compilation is done java 8 compiler your code looks like this:
```
class A {
A() {
this.m1(); // at runtime this refers to Main class instance
System.out.println("A constructor");
}
void m1() {
System.out.println("A m1");
}
}
public class Main extends A {
public Main() { }
public static void main(String[] args) throws Exception {
Main m = new Main();
m.m1();
}
void m1() {
System.out.println("Main m1");
}
}
```
Now to answer your first question: No. You cannot unless you are creating an instance of A(actual object of A).
To your second question:
after making both m1's static compilation looks like this:
```
class A {
A() {
m1(); // resolves to A's m1
System.out.println("A constructor");
}
static void m1() {
System.out.println("A m1");
}
}
public class Main extends A {
public Main() {
}
public static void main(String[] args) throws Exception {
new Main();
}
static void m1() {
System.out.println("Main m1");
}
}
```
Now no matter which instance(A or Main) you create you will see A's m1 excuted. | 1.(When two methods are instance method) If you are inside the A (parent) class, if you call `m1()`; or `this.m1();` you will call the A version of the `m1()` method but if you are inside the main class (child), if you call `m1();` you will call the main version of m1 although if you call `super.m1();` you will be calling the A version of m1 method.
2.(If the methods are static) you can call each version wherever you want, without and object of a class, for example, you can invoke main´s m1 method inside the A block with the following line `Main.m1(); // ClassName.StaticMethodName();` |

62,673,139 | I am using Django 2.2 and Python 3.6.
I deployed a Django REST server using AWS EB, but I get the following error.
It works fine on the local side, but an error occurs in the EB instance.
As a result of my analysis, request.user is recognized normally on the local, but on the EB it is marked as an anonymous user.
I am using the same code, but why does this happen?
```

"PAGE_SIZE": 10,
"DEFAULT_AUTHENTICATION_CLASSES": [
"rest_framework_simplejwt.authentication.JWTAuthentication",
],
}

I changed the above code to the below code because it is a problem of AUTHENTICATION\_CLASSES, but I still get an error.

] | The first problem is that `AnonymousUser` does not have an `is_admin` property in django. You can maybe check `is_superuser` or check if your user is authenticated before calling `is_admin` on it. See [How to check if a user is logged in (how to properly use user.is\_authenticated)?](https://stackoverflow.com/questions/3644902/how-to-check-if-a-user-is-logged-in-how-to-properly-use-user-is-authenticated) for that.
About the difference between local and distant, I would guess that you're logged in on your local app but not on your distant app. This is why `AnonymousUser` gets returned by `request.user` on your distant app. | The problem I encountered was the same as the cause in this [question](https://stackoverflow.com/questions/62686560/is-there-an-aws-inbound-policy-that-interferes-with-authorization-bearer-toke).
This is also a known issue on the AWS forums.
**You can fix it in the following way:**

62,673,342 | I have lots of small files. To save file handles and improve IO efficiency, these files are packed into a big single file. However, for some reason, these small files should be able to update in runtime. So Updating and reading different parts of a big single file at the same time by different threads is required.
Because of the memory limit, mmap is not a good choice. I have to implement it by myself. But I'm concerned about is it safe to read and write different parts of a single file at the same time on iOS/Android. How can I make sure the block which is being writing will not read by other thread.
Should I implement the whole feature by thread locks or there has been some mature technic to do the same work?
By the way, I use C++ for my project. But Java & Obj-C is also an option.
User case example:
My project is an RPG game. When people see an item that is not stored in the original package, the game will load it from the server and save it into the disk automatically and immediately.
One item corresponding to a single file. Each file almost 300KB~1.5MB. There are 3000~5000 items on the server. In the worst case, people will save thousands of files locally.
The good thing is my user can load the items on demand to save the storage. And when updating only changed items will be redownloaded. But thousands of files will lead to a high risk of running out of FD or other resources.
That's why I would like to pack these small files into a single big package file. But I still want to keep the ability to update/add a single file. | 2020/07/01 | [

62,673,404 | I am trying to run shell script in which I am matching two string values but getting above error. Can you please help me how to resolve this?
Example:
run command:
```
sh script.sh AMPIL Group_1

I am using below shell script:
```
if [ $Execution_Order == "Group_1" ]

rm sqoop_queries_meta_data_Group_1.txt
echo $sqoop_queries >> sqoop_queries_meta_data_Group_1.txt

echo $sqoop_queries >> sqoop_queries_meta_data_Group_2.txt
else
rm sqoop_queries_meta_data.txt

] | The string comparison operator of the `test` command, (i.e. the `[ ... ]` syntax is defined as a single equals sign. Some shells (including `bash`) also accept the double-equals but it's not part of the original POSIX spec.
Thus, you might want to change your queries to:
```
if [ "$Execution_Order" = "Group_1" ]
then
rm sqoop_queries_meta_data_Group_1.txt
echo "$sqoop_queries" >> sqoop_queries_meta_data_Group_1.txt
elif [ "$Execution_Order" = "Group_2" ]
then
rm sqoop_queries_meta_data_Group_2.txt
echo "$sqoop_queries" >> sqoop_queries_meta_data_Group_2.txt
else
rm sqoop_queries_meta_data.txt
echo "$sqoop_queries" >> sqoop_queries_meta_data.txt
fi
``` | I don't see why you need an `elif` in this special example. Also, I don't understand why you first remove a file and then append to that very file. How about
```
eo="${Execution_Order:+_$Execution_Order}"
echo "$sqoop_queries" > "sqoop_queries_meta_data$eo.txt"
```
? The main difference is that if `Execution_Order` would be, say, Group\_3, it would create a file sqoop\_queries\_meta\_data\_Group3 in my solution, while it would write to sqoop\_queries\_meta\_data.txt in your attempt, but if this is a problem in your context, this can easily be fixed.
Explanation: The `:+` sets `eo` to empty, if `Execution_Order` is empty, and to `_$Execution_Order` otherwise. |

] | Try to write this in your template
```
<textarea [attr.id]="_id?_id:null" [attr.class]="_class?_class:null"></textarea>
```
This will check if your `_id` and your `_class` are set, if not the return value will be `null`, this will have the effect of removing the attribute and so not showing an undefined value. | You can add a default value to both your `@Input` just like any other property:
```
@Input('id') _id:string = "defaultId";
@Input('class') _class:string = "defaultClass"
```
When an `@input` value is `undefined` it will take the default value.
If you want to completely hide the `CustomTextBox` in case no `_id` or `_class` are provided you can try:
```
showTextBox: boolean = false;
ngOnInit(): void {
if(_id !== undefined && _class !== undefined){
showTextBox= true;
}
}
```
and in your html file:
```
<CustomTextBox *ngIf ="showTextBox"></CustomTextBox>

62,673,415 | Context
-------
My project looks like this:
```
+-- screens
| +-- main_screen.dart
| +-- details_screen.dart
| +-- summary_screen.dart
+-- viewmodels
| +-- main_screen_viewmodel.dart
| +-- details_screen_viewmodel.dart
| +-- summary_screen_viewmodel.dart
+-- services
| +-- caching.dart
| +-- api.dart
+-- lib.dart
```
Screens use a ViewModel that contains all of the data it requires; any change to the model results in a rebuild of the view:
```dart
// main_screen.dart
class _MainScreenState extends State<MainScreen> {
final model = MainScreenViewModel();
Widget build(BuildContext context) {
return ChangeNotifierProvider<MainScreenViewModel>(
create: (BuildContext context) => widget.model,
child: Consumer<MainScreenViewModel>(
builder: (context, model, child) => Text(model.welcomeMessage)
)
);
}
}
```
This all looks like a fairly standard Provider implementation; time to describe my issue.
Problem
-------
I have a class called `Caching` that handles the caching of API requests. When a change is made to a resource (e.g. Transactions), I'd like to trigger a refresh of all my viewmodels so the UI displays the updated data.
How can I access the ViewModels from within my Caching class to trigger the update? | 2020/07/01 | [
"https://Stackoverflow.com/questions/62673415",
"https://Stackoverflow.com",
"https://Stackoverflow.com/users/2022751/"
] | I used to handle this using `StreamController`, For example :
Inside my view model i have this portion of code, this line to create listener for the Stream `_basketService.historiesStreamNotifier.listen((value) async {await fetchData();});`
inside the service declare my `StreamController` :
```
StreamController<int> _historiesStreamControllerNotifier =
StreamController<int>.broadcast();
Stream<int> get historiesStreamNotifier =>
_historiesStreamControllerNotifier.stream;
```
so whenever i need to refresh my view model from my service i simply call
`_historiesStreamControllerNotifier.sink.add(0);`
This will trigger the callback defined with `.listen(...)` | On your Services that must update e.g Service A & Service B add this
```
final StreamController<int> _dataStreamController = StreamController<int>.broadcast();
Stream<int> get dataStream => _dataStreamController.stream;
```
On your BASE Model, add a listen() method, so its gonna be accessible to all viewmodels
```
void listen() {
final aService = locator<ServiceA>();
final bService = locator<ServiceB>();
aService.dataStream.listen((_) async {
notifyListeners();
});
bService.dataStream.listen((_) async {
notifyListeners();
});
}
```
On View
```
BaseView<BViewModel>(
onModelReady: (viewModel) {
viewModel.listen();
},builder: (context, viewModel, child) {
return AlignedGridView.count( ...
```
On Services again, once you updated something on service and you want to notify all listening viewmodels on that change
```
... some successful api request ...
_dataStreamController.sink.add(0);
