(Flutter/Dart-PDF) How to handle long text in a Multipage Table without causing InstanceOfTooManyPages error? |

I use the example of `plotmf` function in the [document](https://www.mathworks.com/help/fuzzy/plotmf.html) and at the same time, I want to change the font of `x` label. So I use the code below:
```
fis = readfis('tipper');
plotmf(fis,'input',1)
xlabel('\fontname{宋体} 论域')
ylabel('\fontname{宋体} 隶属度')
```
But the `xlabel` shows the in its original state as `\fontname{宋体} 论域`, and the `ylabel` is what I want. The figure is below:
[the figure](https://i.stack.imgur.com/Ox3ju.png)
So why does the `fontname` command in `xlabel` not work?
Then I use another method avoiding the `fontname` in `label` using `gca` as
```
fis = readfis('tipper');
plotmf(fis,'input',1)
xlabel('论域')
ylabel('\fontname{宋体} 隶属度')
set(gca, 'FontName', '宋体');
```
And it works. But I want to simultaneously show different fonts in a `label`, such as `xlabel('\fontname{宋体} 时间\fontname{Times new roman} (s)'`, and `gca` fails.
So this is not a good method, and it doesn't explain the issue. |
Why cannot I set font of `xlabel` in `plotmf` in MATLAB? |

I have a suggestion: There is a method in WCF: **BeforeCall**.
The **BeforeCall** method is called before the client call is sent, that is, before the request is passed to the service.
It can help you verify that the enumeration data sent by the client is valid.
public object BeforeCall(string operationName, object[] inputs)
{
// Judge
}
I think it's a very effective way to judge a request before it is sent. |

> Regex Match a pattern that only contains one set of numerals, and not more
I would start by writing a _grammar_ for the "forgiving parser" you are coding. It is not clear from your examples, for instance, whether `<2112` is acceptable. Must the brackets be paired? Ditto for quotes, etc.
Assuming that brackets and quotes do not need to be paired, you might have the following grammar:
##### _sign_
`+` | `-`
##### _digit_
`0` | `1` | `2` | `3` | `4` | `5` | `6` | `7` | `8` | `9`
##### _non-sign-non-digit_
_any-character-that-is-not-a-sign-or-digit_
##### _integer_
[ _sign_ ] _digit_ { _digit_ }
##### _prefix_
[ _any-sequence-without-a-sign-or-digit_ ]
_prefix_ _sign_ _non-sign-non-digit_ [ _any-sequence-without-a-sign-or-digit_ ]
##### _suffix_
[ _any-sequence-without-a-digit_ ]
##### _forgiving-integer_
_prefix_ _integer_ _suffix_
Notes:
- Items within square brackets are optional. They may appear either 0 or 1 time.
- Items within curly braces are optional. They may appear 0 or more times.
- Items separated by `|` are alternatives from which 1 must be chosen
- Items on separate lines are alternatives from which 1 must be chosen
One subtlety of this grammar is that integers can have only one sign. When more than one sign is present, all except the last are treated as part of the _prefix_, and, thus, are ignored.
Are the following interpretations acceptable? If not, then the grammar must be altered.
- `++42` parses as `+42`
- `--42` parses as `-42`
- `+-42` parses as `-42`
- `-+42` parses as `+42`
Another subtlety is that whitespace following a sign causes the sign to be treated as part of the prefix, and, thus, to be ignored. This is perhaps counterintuitive, and, frankly, may be unacceptable. Nevertheless, it is how the grammar works.
In the example below, the negative sign is ignored, because it is part of the prefix.
- `- 42` parses as `42`
### A solution without `std::regex`
With a grammar in hand, it should be easier to figure out an appropriate regular expression.
My solution, however, is to avoid the inefficiencies of `std::regex`, in favor of coding a simple "parser."
In the following program, function `validate_integer` implements the foregoing grammar. When `validate_integer` succeeds, it returns the integer it parsed. When it fails, it throws a `std::runtime_error`.
Because `validate_integer` uses `std::from_chars` to convert the integer sequence, it will not convert the test case `2112.0` from the OP. The trailing `.0` is treated as a second integer. All the other test cases work as expected.
The only tricky part is the initial loop that skips over non-numeric characters. When it encounters a sign (`+` or `-`), it has to check the following character to decide whether the sign should be interpreted as the start of a numeric sequence. That is reflected in the "tricky" grammar for _prefix_ given above, where a sign must not be followed by a sign or digit, if it is to be treated as part of the prefix.
```lang-cpp
// main.cpp
#include <cctype>
#include <charconv>
#include <iomanip>
#include <iostream>
#include <stdexcept>
#include <string>
#include <string_view>
bool is_digit(unsigned const char c) {
return std::isdigit(c);
}
bool is_sign(const char c) {
return c == '+' || c == '-';
}
int validate_integer(std::string const& s)
{
enum : std::string::size_type { one = 1u };
std::string::size_type i{};
// skip over prefix
while (i < s.length())
{
if (is_digit(s[i]) || is_sign(s[i])
&& i + one < s.length()
&& is_digit(s[i + one]))
break;
++i;
}
// throw if nothing remains
if (i == s.length())
throw std::runtime_error("validation failed");
// parse integer
// due to foregoing checks, this cannot fail
if (s[i] == '+')
++i; // `std::from_chars` does not accept leading plus sign.
auto const first{ &s[i] };
auto const last{ &s[s.length() - one] + one };
int n;
auto [end, ec] { std::from_chars(first, last, n) };
i += end - first;
// skip over suffix
while (i < s.length() && !is_digit(s[i]))
++i;
// throw if anything remains
if (i != s.length())
throw std::runtime_error("validation failed");
return n;
}
void test(std::ostream& log, bool const expect, std::string s)
{
std::streamsize w{ 46 };
try {
auto n = validate_integer(s);
log << std::setw(w) << s << " : " << n << '\n';
}
catch (std::exception const& e) {
auto const msg{ e.what() };
log << std::setw(w) << s << " : " << e.what()
<< ( expect ? "" : " (as expected)")
<< '\n';
}
}
int main()
{
auto& log{ std::cout };
log << std::left;
test(log, true, "<2112>");
test(log, true, "[(2112)]");
test(log, true, "\"2112, \"");

return 0;

I have added my asset files in my projects root directory, which contains images, fonts and sounds.
<img src="https://i.stack.imgur.com/R9nd1.png" height="350" alt="assets folder">
Added the assets in `pubspec.yaml` file like this:
```yaml
flutter:

Then I try to add an image through `Image.asset` like the code below:

body: Column(
children: [
Text(
"riyad",

),
Image.asset("car_android.png") <-- like this
],
),
);
```
But it shows me an exception that failed to load the asset:
```
The following assertion was thrown resolving an image codec:

My traceback exception:

look how the system sees your given path
print(path)

**This is the output because of the backslashes "\\" are used to escape characters that have a special meaning like "\n" making a new line character and I can see "\f" in your path.**
to avoid this problem just use r'' the backslashes will be treated as literal characters and not escaping characters.

you need to pass the click event handlers from the parent component to the child component !Then, the child component can use these handlers to trigger actions in the parent component...
-> In the parent component, define click event handlers for the action buttons (btnEditClick and btnDeleteClick)..
-> Pass these event handlers to the child component as part of the columns input,
-> In the child component, modify the template to use the passed event handlers for the action buttons.
->When the action buttons are clicked in the child component, trigger the corresponding event handler passed from the parent component !
\\modified code\\
#Parent Component
export class ParentComponent {
// Define click event handlers
btnEditClick(item: any) {
console.log('Edit clicked:', item);
}
btnDeleteClick(item: any) {
console.log('Delete clicked:', item);
}
// Your existing code for column definition
}
-------------------------------------------------------------|
#Child Component Template
<!-- Inside the table -->
<td mat-cell *matCellDef="let element">
<span *ngIf="column.name !== 'actions'">{{ element[column.name] }}</span>
<span *ngIf="column.name === 'actions'">
<button mat-icon-button (click)="column.click(element)">
<mat-icon>{{ column.icon }}</mat-icon>
</button>
</span>
</td>
-------------------------------------------------------------|
With this setup, when the action buttons are clicked in the child component... they trigger the corresponding event handlers(btnEditClick or btnDeleteClick)passed from the parent component.
--->You'll also need to update your columns definition in the parent component to include the click property <---
:
this.columns = [
// Other column definitions...
{
title: "Action",
name: 'actions',
buttons: [
{
type: "",
icon: "edit",
class: "tbl-fav-edit",
title: ActionButtonType.Edit,
click: this.btnEditClick.bind(this), // Bind the event handler
},
{
type: "",
icon: "trash-2",
class: "tbl-fav-delete",
title: ActionButtonType.Delete,
click: this.btnDeleteClick.bind(this), // Bind the event handler
}
]
}
];
-------------------------------------------------------------|
!{Make sure to bind the event handlers (btnEditClick and btnDeleteClick) to the parent component instance using...bind(this),so they maintain the correct context when passed to the child component}!

I'm trying to find a bot/app that will find popular Twitter posts (based on particular niches, or inputted user handles), reword them (using AI), and then repost them, scheduled over a set time period.
Do any such bots/apps exist?
If not, are there any workarounds I could use to achieve the same thing?
Thanks in advance!

I am trying to convert my discord image into Base 64 from a link so it can be used in Googles [Gemini Pro Vision Model](https://ai.google.dev/tutorials/node_quickstart#generate-text-from-text-and-image-input). However I am encountering an error every time. I believe it occurs when the axios function is run, but I am not 100% sure.
#### Code:
```javascript
async function run(message) {
const model = genAI.getGenerativeModel({ model: "gemini-pro-vision" });
console.log("Pass 1")
const imageAttachmentUrls = message.attachments
.filter(attachIsImage)
.map((attachment) => attachment.url)
.filter((url) => !!url);
console.log("Pass 2")
if (imageAttachmentUrls.length === 0) {
console.log("No valid image attachments found in the message.");
return;
}
console.log("Pass 3")
function getBase64(url) {
console.log("Pass 5")
return axios
.get(url, {
responseType: 'arraybuffer'
})
.then(response => Buffer.from(response.data, 'binary').toString('base64'))
}
console.log("Pass 4")
console.log(imageAttachmentUrls[0]);
const image = {
inlineData: {
data: await getBase64(imageAttachmentUrls[0]),
mimeType: "image/png",
},
};
console.log("Pass 6")
const prompt = "What's this picture?";
const result = await model.generateContent([prompt, image]);
console.log(result);

I managed to come upon this in a Github discussion this approach does not require you to install any packages.
```
Widget build(BuildContext context) {

duration: const Duration(milliseconds: 250),
child: isFabExtended ? const Text("Create Action") : const SizedBox(),
),
icon: const Icon(Icons.add),

Here `isFabExtended` denotes whether the FAB should also contain the label. Feel free to use your own logic to toggle this. |

I have installed a self hosted agent in my company's private cloud VM (followed [documentation from Microsoft][1] and it got successfully installed as service and running.
Now I tried to test it as system startup, so rebooted my machine. After reboot when I am checking the status of service using `sudo ./svc.sh status` seeing below error

What you currently experience is the expected behavior. Since the field type is `Rich text` all embedded contents(images or entries) will be linked like you have seen.
For graphQL, you can retrieve `raw` and `references` from your rich text and use like so:
_returnHtmlFromRichText({raw, references}) {
return documentToHtmlString(raw,
{
renderNode: {
[BLOCKS.EMBEDDED_ASSET]: (node, children) => {
if (!references || !node) {
return null;
}
const referenceNode = references.find(
(reference) => node.data.target.sys.id ===
reference.contentful_id
);
const imageURL = 'https:' + ${referenceNode.media[0].file.url;
return `<img src="${imageURL}"/>`
},
}
}
);
}
For Rest API, you need to make an additional request to get the asset you want.
_returnHtmlFromRichText(richText) {
return documentToHtmlString(richText,
{
renderNode: {
[BLOCKS.EMBEDDED_ASSET]: (node, children) => {
const response = await fetch('https://cdn.contentful.com/spaces/<YOUR_SPACE_ID>/assets/${assetId}?access_token=<YOUR_ACCESS_TOKEN>');
const data = await response.json();
const imageURL = 'https:' + data.fields.file.url
return `<img src="${imageURL}"/>`
},
}
}
);
}
assetId = `target.sys.id`
You can expand this logic to cater to other cases if you need to also handle other embedded contents like `Entries` or `Inline-Entry`.
`raw` and `references` are basically `richText.raw` and `richText.references`
|
You could write a `statfun` and use it in `by`.

+ rk <- \(x, m, z=12) rank(replace(x, m < z, NA), 'keep', 'max') ## rank fun
+ pctl <- \(x) round((x - 1L)/length(na.omit(x) - 1)*100L) ## perc fun
+ o <- lapply(stat, \(s) {

+ p <- pctl(r)

What you are trying to do should be done using JavaScript function you cannot bind onchange function directly to php script. you have to use either pure javascript function or using javascript library like jquery to make ajax request call to the php script and add the data to mysql database
Check Below code using pure javascript
input.html
<code>
<input type="button" value="Home" class="homebutton" id="btnHome" onClick="add_record();" />
<script type="text/javascript">
function add_record(){
var data= document.getElementById("btnHome").value; // get value from input
xhttp.open("GET", "php_file.php?field="+data, true); // get request url with field parameter
xhttp.send(); // make request
}
</script>
</code>
php_file.php
<code>
<?php
$servername = "localhost:3306";
$username = "deneme";
$password = "deneme";
$dbname = "deneme";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$field_data = $_GET['field']; // get field parameter from request url
// insert $filed_data into database . You can add as much as fields in request parameter
$sql = "INSERT INTO please (field) VALUES ('$field_data')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>

Note: I have tested the same grpc call using postman using same server address and port and it is working. This error only occur when running my client. |
I am using the product function of polars.
I have a dataframe with 1458644 rows and one of its column is 'vendor_id' and has unique values = [1,2].
While trying to run the product function on the entire df, it return 0.
However, if i run the product function on unique values it returns 2.
Any reason as to why this is happening?

So I've been learning and using **Signals** in Angular, and it's exciting. However, there are some use cases where I feel there's some friction. I can't figure out a good pattern when you have a component with `input signals`, and you want to trigger a re-fetch of data whenever some input value changes.
`computed` is obviously not the way to go since they can't be async. And `effect`, according to the docs, shouldn't modify component state. So that seems like a no-go as well. And ngOnChanges is being deprecated (long term) in favor of Signals-based components and zoneless.
Consider the following component:
```
@Component()
export class ChartComponent {
dataSeriesId = input.required<string>();
fromDate = input.required<Date>();
toDate = input.required<Date>();
private data = signal<ChartData | null>(null);
}
```
Whenever one of the input signals gets a new value, I want to trigger a re-fetch of data, and `update` the value of the private `data` signal.
How would one go about this? What's the best practice? Effect and bypass the rule to modify state? |

}
```
```

function boldTextInLines() {

body.editAsText().setBold(i, 0, endPos, true);
}else{

}
}
}
```
The parameters passed to `setBold` appear to be correct:
* `i`: The line index
* `0`: The starting offset of the text in the line
* `endPos + 1`: The ending offset of the text in the line (one character after the colon)
* `true`: To set the text as bold
> Exception: The parameters (number,number,number,(class)) don't match the method signature for DocumentApp.Text.setBold. boldTextInLines @ Kod.gs:14
This is the error that was thrown and how can I correct it?

[My code for executing queries](https://i.stack.imgur.com/y2YcG.png)
I execute my queries through this and I observed that after every query the process goes in sleep and not releases. One of the processes is like this:
# Id, User, Host, db, Command, Time, State, Info
189, root, localhost:49214, erp_software_db, Sleep, 1334, ,
After I close the connection all the processes are killed but on restarting the id continues from where it was left and not 1.
But after certain time many processes are just accumulated and I get an error saying "Too many connections".
Can anyone guide me through this?? Thanks for your replies in advance. |

I am trying to use **WMI** to query system information on some clients on our network. We have successfully used administrator users to accomplish this in C# but now we want to switch to users **without admin permissions** (just enough permissions to run wmi queries accross the network) due to security reasons.
I can successfully run wmi queries using powershell as a user without elevated admin permissions on a remote host using `Get-WmiObject Win32_ComputerSystem -ComputerName pcname`
I have an application trying to accomplish the same thing using C#:
The following snippet should use the user which runs the application without further authentication required:
```c#
CimSession session = CimSession.Create(hostname);
// A method called GetWMI(string query, string namespace) will then execute the wmi query on the remote machine
session.QueryInstances(namespace, "WQL", query)
```
I also tried using in-code authentication with dcomsettings (of course using the same user credentials which can perform the same request using powershell as seen above):
```c#
DComSessionOptions dComOptions = new DComSessionOptions();
dComOptions.Impersonation = ImpersonationType.Impersonate;
var password = new SecureString();
settings.WMIPassword.ToList().ForEach(x => password.AppendChar(x));
dComOptions.AddDestinationCredentials(new CimCredential(PasswordAuthenticationMechanism.Default, settings.WMIDomain, settings.WMIUsername, password));
CimSession session = CimSession.Create(hostname, dComOptions);
// A method called GetWMI(string query, string namespace) will then execute the wmi query on the remote machine
session.QueryInstances(namespace, "WQL", query)
```
Both of these ways end up throwing a `CimException: Access Denied` error.
Is there maybe another way to do this in C#? My research could not come up with anything that would work - maybe there is some way I don't know about yet.
We have sunk countless hours into research and debugging but nothing seems to work.
For future reference I have found some older posts regarding some similar issues (most information on the internet about wmi is over a decade old):
- https://stackoverflow.com/questions/10552268/wmi-using-a-non-admin-account-to-query-server
- The following is actually my own post regarding the same issue - it was resolved as we tried using administrator permissions on the remote machine which would work but we now need it to work with as little permissions as possible eg. no administrator

- https://stackoverflow.com/questions/4990890/delphi-wmi-query-on-a-remote-machine
I have tried all the suggestions from these posts - some of them seemed promising but turned out to not be the solution of my problem.
Here is a summary of what we tried:
- We granted all permissions in "wmimgmt.msc" to the root namespace and applied them to "This namespace and subnamespaces"
- We added the user to the Local "Distributed COM Users" group
- We added the user to the "Performance Monitor Users" and the "Remote Management Users" groups
- We checked for any firewall issues and can assure that that should not be the problem
- We also granted remote launch and activation permissions
Here is our configuration in "wmimgmt.mcs" which should apply to the root namespace and all namespaces below (it's in German but shows that all permissions should apply to all namespaces):
[![wmimgmt.msc Configuration on the root namespace][1]][1]
Furthermore I found an old post in the microsoft docs stating that this is actually impossible (which is hard to believe as I already got it to work using powershell): https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc771551(v=ws.11)?redirectedfrom=MSDN
> To perform this task on the local computer, you must be logged on as a member of the local Administrators group.
>To perform this task on a remote computer, the account with which you are logged on must be a member of the Administrators group of that computer.
If there is anything more I can provide to clear things up please let me know.
Any leads would be highly appreciated - if any of my points in this post help other people in the future it was at least worth the research.

As far as I have seen with Laravel projects, comments in blades (`{{-- ... --}}`) trigger strange behaviors, such as preventing new lines or even inserting tabs.
Strangely this doesn't always seem to happen, I think it is related to other Laravel code in the comment.

I would start by writing a _grammar_ for the "forgiving parser" you are coding. It is not clear from your examples, for instance, whether `<2112` is acceptable. Must the brackets be paired? Ditto for quotes, etc.
Assuming that brackets and quotes do not need to be paired, you might have the following grammar:
##### _sign_
`+` | `-`
##### _digit_
`0` | `1` | `2` | `3` | `4` | `5` | `6` | `7` | `8` | `9`
##### _non-sign-non-digit_
_any-character-that-is-not-a-sign-or-digit_
##### _integer_
[ _sign_ ] _digit_ { _digit_ }
##### _prefix_
[ _any-sequence-without-a-sign-or-digit_ ]
_prefix_ _sign_ _non-sign-non-digit_ [ _any-sequence-without-a-sign-or-digit_ ]
##### _suffix_
[ _any-sequence-without-a-digit_ ]
##### _forgiving-integer_
_prefix_ _integer_ _suffix_
Notes:
- Items within square brackets are optional. They may appear either 0 or 1 time.
- Items within curly braces are optional. They may appear 0 or more times.
- Items separated by `|` are alternatives from which 1 must be chosen
- Items on separate lines are alternatives from which 1 must be chosen
One subtlety of this grammar is that integers can have only one sign. When more than one sign is present, all except the last are treated as part of the _prefix_, and, thus, are ignored.
Are the following interpretations acceptable? If not, then the grammar must be altered.
- `++42` parses as `+42`
- `--42` parses as `-42`
- `+-42` parses as `-42`
- `-+42` parses as `+42`
Another subtlety is that whitespace following a sign causes the sign to be treated as part of the prefix, and, thus, to be ignored. This is perhaps counterintuitive, and, frankly, may be unacceptable. Nevertheless, it is how the grammar works.
In the example below, the negative sign is ignored, because it is part of the prefix.
- `- 42` parses as `42`
### A solution without `std::regex`
With a grammar in hand, it should be easier to figure out an appropriate regular expression.
My solution, however, is to avoid the inefficiencies of `std::regex`, in favor of coding a simple "parser."
In the following program, function `validate_integer` implements the foregoing grammar. When `validate_integer` succeeds, it returns the integer it parsed. When it fails, it throws a `std::runtime_error`.
Because `validate_integer` uses `std::from_chars` to convert the integer sequence, it will not convert the test case `2112.0` from the OP. The trailing `.0` is treated as a second integer. All the other test cases work as expected.
The only tricky part is the initial loop that skips over non-numeric characters. When it encounters a sign (`+` or `-`), it has to check the following character to decide whether the sign should be interpreted as the start of a numeric sequence. That is reflected in the "tricky" grammar for _prefix_ given above, where a sign must not be followed by a sign or digit, if it is to be treated as part of the prefix.
```lang-cpp
// main.cpp
#include <cctype>
#include <charconv>
#include <iomanip>
#include <iostream>
#include <stdexcept>
#include <string>
#include <string_view>
bool is_digit(unsigned const char c) {
return std::isdigit(c);
}
bool is_sign(const char c) {
return c == '+' || c == '-';
}
int validate_integer(std::string const& s)
{
enum : std::string::size_type { one = 1u };
std::string::size_type i{};
// skip over prefix
while (i < s.length())
{
if (is_digit(s[i]) || is_sign(s[i])
&& i + one < s.length()
&& is_digit(s[i + one]))
break;
++i;
}
// throw if nothing remains
if (i == s.length())
throw std::runtime_error("validation failed");
// parse integer
// due to foregoing checks, this cannot fail
if (s[i] == '+')
++i; // `std::from_chars` does not accept leading plus sign.
auto const first{ &s[i] };
auto const last{ &s[s.length() - one] + one };
int n;
auto [end, ec] { std::from_chars(first, last, n) };
i += end - first;
// skip over suffix
while (i < s.length() && !is_digit(s[i]))
++i;
// throw if anything remains
if (i != s.length())
throw std::runtime_error("validation failed");
return n;
}
void test(std::ostream& log, bool const expect, std::string s)
{
std::streamsize w{ 46 };
try {
auto n = validate_integer(s);
log << std::setw(w) << s << " : " << n << '\n';
}
catch (std::exception const& e) {
auto const msg{ e.what() };
log << std::setw(w) << s << " : " << e.what()
<< ( expect ? "" : " (as expected)")
<< '\n';
}
}
int main()
{
auto& log{ std::cout };
log << std::left;
test(log, true, "<2112>");
test(log, true, "[(2112)]");
test(log, true, "\"2112, \"");
test(log, true, "-2112");
test(log, true, ".2112");
test(log, true, "<span style = \"numeral\">2112</span>");
log.put('\n');
test(log, true, "++42");
test(log, true, "--42");
test(log, true, "+-42");
test(log, true, "-+42");
test(log, true, "- 42");
log.put('\n');
test(log, false, "2112.0");
test(log, false, "");
test(log, false, "21,12");
test(log, false, "\"21\",\"12, \"");
test(log, false, "<span style = \"font - size:18.0pt\">2112</span>");
log.put('\n');
return 0;
}
// end file: main.cpp
```
### Output
The "hole" in the output, below the entry for 2112.0, is the failed conversion of the null-string.
```lang-none
<2112> : 2112
[(2112)] : 2112
"2112, " : 2112
-2112 : -2112
.2112 : 2112
<span style = "numeral">2112</span> : 2112
++42 : 42
--42 : -42
+-42 : -42
-+42 : 42
- 42 : 42
2112.0 : validation failed (as expected)
: validation failed (as expected)
21,12 : validation failed (as expected)
"21","12, " : validation failed (as expected)
<span style = "font - size:18.0pt">2112</span> : validation failed (as expected)

**Problem :-**
You import like below.
```python
from django.contrib.auth import authenticate, login
```
And then you use it as below.
```python
user = authenticate(request, username=student_id, password=password)
#and
login(request, user)
```
Which are built in methods.
This `authenticate` function doesn't use your password field in your model.(unless you already wrote code for custom authentication backend and didn't post here.)
So, when you try to log in, that user doesn't exist in django built-in auth system.
**Answers :-**
1)
I suggest you to use django built-in auth system.
Django already include built-in auth system, which you can customise for your needs.
2)
Write a custom authentication backend. It's not very hard to make a custom authentication backend.
It's the only way to make this work, if you want to keep using custom password fields in models.

For testing my app, I need to send a mail over my companies mailhost.
Unfortunately I have to use a tunnel to connect to that host and so sending mail is rejected because:
```text
tls: failed to verify certificate: x509: certificate is valid for *.example.com, example.com, not host.docker.internal
```
Is there any way around this? Can I disable TLS?
I'm using github.com/jhillyerd/enmime
**Update after 2 comments**
1. I do **not** want to switch of TLS on the mailhost. I simply want to tell my net/smtp's Sendmail or enmime's Send to not do TLS verification. I already achieved that by copying Sendmail's code, leaving out the TLS-Part. But I don't like that approach as it feels very "hacky".
2. I'm working in a VPN and there are no credentials required when sending mails, as the mailhost can only be reached by a small set of known hosts.
3. This is also why I need a tunnel through a jumphost in order to reach the mailhost from my developer machine:
Dockercontainer --> DevMac ---> Jumphost ---> Mailhost
So I do a
`ssh -L9925:mailhost.example.com:25 me@jumphost.example.com`
That's why I have defined the mailhost to be "host.docker.internal:9925".
Maybe there is another idea how I can reach the mailhost by its real name?

Here's a working solution. As I said in my comment, using regular expressions makes it far easier to retrieve the "highlighted" word. Note that it would be quite easy (by storing the word category delimiters in a dictionary, and replacing the 3 dictionaries with one dictionary of dictionaries) to make the code more flexible (adding new categories) while avoiding the repetition of `if ...` statements.
```
import re
sentences = [
"Es (duftete) nach Erde und Pilze",
"die [Wände] waren mit Moos überzogen.",
"Ihr zerrissenes [Gewand] war wieder wie neu",
"Er saß da wie verzaubert und schaute sie an und konnte seine Augen nicht {mehr} von ihr abwenden",
"Da sie durchscheinend waren, sahen sie aus wie aus rosa [Glas], das von innen erleuchtet ist.",
]
def getWordsSelected(sentences):
# the parameter sentences is a list of the previous sentences sample showed
verbDict = {}
subsDict = {}
adjDict = {}
for wordSentenceToSearch in sentences:
# SUBSTANTIVE
if (substantive := re.findall(r'\[([^]]*)', wordSentenceToSearch)):
subsDict.setdefault(substantive[0], []).append((wordSentenceToSearch, "substantive"))
# VERB
if (verb := re.findall(r'\(([^)]*)', wordSentenceToSearch)):
verbDict.setdefault(verb[0], []).append((wordSentenceToSearch, "verb"))
# ADJ
if (adj := re.findall(r'\{([^}]*)', wordSentenceToSearch)):
adjDict.setdefault(adj[0], []).append((wordSentenceToSearch, "adjective"))
print(subsDict)
print(verbDict)
print(adjDict)
```
OUTPUT:
```
getWordsSelected(sentences)
{'Wände': [('die [Wände] waren mit Moos überzogen.', 'substantive')], 'Gewand': [('Ihr zerrissenes [Gewand] war wieder wie neu', 'substantive')], 'Glas': [('Da sie durchscheinend waren, sahen sie aus wie aus rosa [Glas], das von innen erleuchtet ist.', 'substantive')]}

The problem was that the effect constructors were not being shared across ```Handler1``` and ```Handler2```, so, it's as if the constructors were different and that is why the handlers didn't recognise the effects. Once I put the effects in one file, then shared this amongst the compilation units, the problem is fixed. |
