Generating Fake Data in Laravel Using Seeders
Published: 2024-04-25 03:01:48

### Step 1: Create Seeders

Run the following Artisan command to create seeders for your courses and services:

```bash
php artisan make:seeder CoursesSeeder
php artisan make:seeder ServicesSeeder
```

### Step 2: Define Seeders

Open the generated seeder files (`database/seeders/CoursesSeeder.php` and `database/seeders/ServicesSeeder.php`) and define the logic to insert fake data into the respective database tables. You can use the Faker library to generate fake data.

Here's an example of how you can define the `run()` method in your `CoursesSeeder` seeder:

```php
use Illuminate\Database\Seeder;
use App\Models\Course;
use Faker\Factory as Faker;

class CoursesSeeder extends Seeder
{
    public function run()
    {
        $faker = Faker::create();

        foreach (range(1, 10) as $index) {
            Course::create([
                'course_name' => $faker->name,
                'course_description' => $faker->sentence,
                'course_fee' => $faker->randomNumber(4),
                'course_total_enroll' => $faker->randomNumber(3),
                'course_total_class' => $faker->randomNumber(2),
                'course_link' => $faker->url,
                'course_image' => $faker->imageUrl(),
            ]);
        }
    }
}
```

### Step 3: Call Seeders

Open the `DatabaseSeeder.php` file located in `database/seeders` directory and call your seeder classes:

```php
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run(): void
    {
        $this->call([
            CoursesSeeder::class,
            ServicesSeeder::class
        ]);
    }
}
```

### Step 4: Run Seeders

Execute the following Artisan command to run the seeders and populate your database with fake data:

```bash
php artisan db:seed
```

Imagine you're building a house, but before you have all the real materials, you use pretend ones to plan everything out. A faux API is like that pretend setup for software developers. It acts like a real interface (the thing that lets different parts of a program talk to each other) but doesn't actually send or receive any real data.

Think of it as a fake version of an API that developers can use while they're building and testing their software. It helps them figure out how everything will work together without messing with real data or systems. It's like a sandbox where they can play around and experiment safely before the real stuff comes into play.

```java
public class Test {
    public static void main(String[] args) {
        // 2次元([2]が２行で[]は要素(列))のString配列を宣言
        String[][] array = new String[2][];
        // 最初の行に2つの要素を持つString配列を初期化
        array[0] = new String[2];
        // 2番目の行に5つの要素を持つString配列を初期化
        array[1] = new String[5];
        // 'i'をASCIIコードの'a'に相当する97で初期化
        int i = 97;

        // 外側のループはarrayの行をイテレート
        for (int a = 0; a < array.length; a++) {
            // 内側のループは各行の長さをチェックするべきだが、arrayの行数（2）でループするため、nullが出力される
            for (int b = 0; b < array.length; b++) { // この行は、array[a].lengthにすれば、null出力はなく、数値で出力されるBの答となる
                // 配列の要素に文字コード'i'を文字列に変換して格納
                array[a][b] = "" + i;
                // 'i'をインクリメントして文字コードを次に進める
                i++;
            }
        }

        // 配列の全ての行について
        for (String[] tmp : array) {
            // 各行の全ての列について
            for (String s : tmp) {
                // 配列の値を出力、未初期化の場合はnullが出力される
                System.out.print(s + " ");
            }
            // 一行出力するごとに改行
            System.out.println();
        }
    }
}
```

このコードの問題点は、8行目でarrayの二次元目の長さではなく、一次元目の長さをループの上限としていることです。`array[a].length`を使用するべき場面で`array.length`が使用されています。このため、arrayの第二行目にある配列は、初期化されていない残りの要素に対して`null`が出力されます。これは、`String`型の配列がデフォルトで`null`値で初期化されるためです。

このコードを実行すると、以下の出力が得られます（選択肢Aに一致）。

```
97 98
99 100 null null null
```

## 追記

`array[a]` で値が `null` でなく実際の値が代入されるのは、Javaにおける配列の動作と初期化の方法に基づいています。具体的に説明します。

### 配列の初期化と代入

Javaでは、配列を宣言した際に、それがプリミティブ型の配列であれば各要素には型のデフォルト値が自動的に設定されます（例：`int` 型の場合は `0`）。一方で、オブジェクト型の配列（例：`String` 型）の場合、各要素は自動的に `null` で初期化されます。

例えば、以下のように配列を宣言しました：

```java
String[][] array = new String[2][];
array[0] = new String[2];  // この時点で array[0][0] と array[0][1] は `null`
array[1] = new String[5];  // この時点で array[1][0] から array[1][4] までが `null`
```

### 値の代入

`array[a]` の各要素に値を代入するには、内部のループを使用して値を設定します。たとえば：

```java
for (int a = 0; a < array.length; a++) {
    for (int b = 0; b < array[a].length; b++) {
        array[a][b] = "Value";  // 文字列 "Value" を各要素に代入
    }
}
```

このループ構造では、`array[a]` が指す各行に対して、その行の長さ（`array[a].length`）だけループを実行し、各要素（`array[a][b]`）に値を代入しています。`array[a].length` はその行の要素数を表しており、この方法によって、行の全ての要素に確実に値が代入され、初期値の `null` が上書きされます。

### `null` が出力されない理由

このようにして各要素に値が代入されるため、配列の要素を出力する際には `null` ではなく、代入された値が表示されます。配列の各行について `array[a].length` の数だけ正確に値を代入することで、配列の全要素が適切に初期化されます。このプロセスにより、各行のすべての要素に具体的な値が存在し、その結果として出力時に `null` が見られなくなるのです。

Tags: webdev, beginners, programming, tutorial
Published: 2024-04-25 02:07:52

To create a PayPal button for a $450 USD purchase, you can use PayPal's button creation tool. Here's how you can do it:

1. Go to the PayPal button creation page: PayPal Button Creation.
2. Select "Buy Now" as the button type.
3. Enter the item name and price. For example, you can enter "Product Name" for the item name and "$450.00" for the price.
4. Select the currency as USD (United States Dollar).
5. Click on "Create Button".
6. Copy the generated button code.
7. Paste the button code into your HTML where you want the button to appear.

Here's an example of how you can integrate the PayPal button code into your HTML:

``<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
  <input type="hidden" name="cmd" value="_xclick">
  <input type="hidden" name="business" value="example@gmail.com">
  <input type="hidden" name="lc" value="US">
  <input type="hidden" name="item_name" value="Product Name">
  <input type="hidden" name="amount" value="450.00">
  <input type="hidden" name="currency_code" value="USD">
  <input type="hidden" name="button_subtype" value="services">
  <input type="hidden" name="no_note" value="0">
  <input type="hidden" name="shipping" value="0.00">
  <input type="hidden" name="bn" value="PP-BuyNowBF:btn_buynow_LG.gif:NonHostedGuest">
  <input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_buynow_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
  <img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>
`

```

Replace "example@gmail.com" with your actual PayPal ID.

Cannot render components after the Fetch() call.
Published: 2024-04-25 01:26:31

Hi, I have a simple code which fetches data and converts it to JSON format. The converted JSON data is then stored in a useState variable. I have been trying to render a "Card" component using the useState variable with map() function. I don't get any errors, but I cannot find the "Card" component on the web page. Here's my code:

`const [actualData,setactualData]=useState(null);
const myrequest=   fetch(fetch_url,{
        method: 'GET',
        // headers: {'Access-Control-Allow-Origin':'*','Content-Type':'application/json'}
    }).then(response => {
        if (!response.ok) {
          throw new Error('Network response was not ok');
        }
        //Actual_Data=response.json();
        return response.json(); // Parse the JSON response
      })
      .then(data => {
        setactualData(data);
        console.log(actualData);
      })
      .catch(error => {
        console.error('There was a problem with the fetch operation:', error);
      });;
    {
         async ()=>{ await actualData.map((item,id)=>(
             <Card name={item.First_Name}/>
         ))}
    }

Building Mobile Apps with React Native
Tags: javascript, beginners, programming, tutorial
Published: 2024-04-25 00:32:55

## Introduction

Mobile apps have become an integral part of our daily lives, and the demand for them is only increasing. With different operating systems, developing a mobile app for both iOS and Android can be time-consuming and costly. React Native, a JavaScript framework, has emerged as a popular choice for building mobile apps as it allows developers to write code for both platforms simultaneously. In this article, we will explore the advantages, disadvantages, and features of building mobile apps with React Native.

## Advantages

One of the biggest advantages of using React Native is its cross-platform compatibility. Developers can write a single codebase and use it for both iOS and Android, reducing development time. It also offers a native-like experience as it uses the device's UI components, resulting in better performance. Another advantage is the availability of a large community, providing support and resources for troubleshooting.

## Disadvantages

Despite its advantages, React Native has some limitations. Its performance may not match that of native apps, and some advanced features may not be supported. Additionally, it may require continuous updates to keep up with the changes in the underlying platforms.

## Features

React Native offers features like hot reloading, which allows developers to see changes made in real-time, making the coding process more efficient. It also allows for integrations with third-party libraries and support for server-side rendering.

### Example of Hot Reloading in React Native

```javascript
// Assuming a React Native component
import React, { useState } from 'react';
import { Text, View, Button } from 'react-native';

const App = () => {
  const [count, setCount] = useState(0);

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>You clicked {count} times</Text>
      <Button title="Click me" onPress={() => setCount(count + 1)} />
    </View>
  );
};

export default App;
```

This simple counter app demonstrates how hot reloading works by allowing developers to see updates in real time as they tweak the UI or logic.

## Conclusion

In conclusion, using React Native for building mobile apps has its advantages and disadvantages. It offers a cost-effective and time-efficient solution for developers, making it a popular choice in the app development industry. However, the choice of framework ultimately depends on the individual project's requirements and the developer's expertise. With React Native continuously improving and evolving, it is definitely a compelling option for building high-quality mobile apps.

## What I Built
<!-- Tell us what your plugin or workflow does and what problem it solves -->

Do you remember this week I created a plugin called [VulnHunterDB](https://dev.to/yowise/vulnhunterdb-coze-plugin-11hf)? 
That was my first plugin ever created, my first steps into TypeScript.
As I mentioned in my original article, I said I am planning to make some improvements (_richer, stronger, cooler_). And that's what happened. Now I integrated 2 packages. One defangs and refangs the URL and the other one checks the IPs, domains, TLDs and Autonomous System numbers. That's the _cooler_ part.



## Demo

<!-- Tell us about your process, what you learned, anything you are particularly proud of, what you hope to do next, etc. -->

Well, VulnHunterDB changed its coat and became iURL. What a change, right? It is indeed. 🌬️ (_this is the wind of change, by the way_).
Ok and what happens with VulnHunterDB? Was it hunted and taken down? No way- it's undergoing a transformation. 😸 The idea will stay the same. And here is the _richer_ and _stronger_ part.

Let me know your thoughts!🫢😸

Day 951 : Walk Away
Tags: hiphop, code, coding, lifelongdev
Published: 2024-04-24 23:06:13

_liner notes_:
- Professional : So... started the day off with a meeting. Then I reviewed a PR for some new docs. Spent the rest of the day working on my project. Definitely hit a wall when I tried to use an external library. The issue I'm running into is that my code is running in the browser which uses ES6 imports, but the external library is using CommonJS. There are other libraries that you can use make it work, but I'm not trying to load up a bunch of other stuff like bundlers. Trying to keep it as simple as possible. It wasn't until the end of the day, that I thought to check if I could create it myself. Did some quick research and it doesn't look that bad. Especially for my use case. I'll work on it tomorrow.

- Personal : Last night was pretty productive. Went through some tracks for the radio show. Converted some hotel points to airline miles. Did some research for my upcoming trip. Tried to get a sample app I made up and running, but kept running into a weird issue. I want to use it as a base for my new side project. Sidenote: I think I found a cool domain name for it, and it's relatively cheap. It was pretty late that I figured out that I needed a .env file with some environment variables. I just had to walk away and work on it the next day. I have no clue what happened with that file. While I was trying to figure that out, I had "X-Men: The Animated Series" on in the background.

![ In the foreground of the picture, there are several wildflowers in focus. The flowers are pink and white, and they are growing in a field of tall grass. The grass is a light brown color, and it is blowing in the wind. The picture is taken from a low angle, and it is looking up at the flowers. The flowers are delicate and beautiful, and they are a reminder of the beauty of nature. The picture is peaceful and serene, and it invites viewers to relax and enjoy the beauty of the moment. The location of the picture is Sleeping Bear Dunes National Lakeshore, Michigan, USA.](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/x0u1i1oipze3swl2hr8h.jpg)

Kept running the prospective domain name in my head through out the day, and I still like it. I think I'll pick it up later tonight. Going to go through Bandcamp to look for some tracks to buy and work on the social media posts. I want to create the .env file to get my sample application working so I can create a starter to be used for my next side project. Need to start booking hotels and flight for my upcoming trip. A lot of stuff to do. Good thing I'm writing up a list. Going to eat dinner and get started. 

Have a great night!
