Laravel development: How to generate code using Laravel Artisan?

Laravel is a popular PHP framework that provides many convenient tools to facilitate the rapid development of web applications. One of them is the Laravel Artisan command line tool.

Use Laravel Artisan to quickly generate code, perform database migration, generate controllers and models, and other operations. In this article, we will explore how to use Laravel Artisan to generate code.

Installing Laravel

First, you need to install Laravel. If you have not installed Laravel, you can refer to the documentation on the Laravel official website to install it.

Introducing Laravel Artisan

Laravel Artisan is a command line tool for Laravel that provides many commands to simplify common development tasks. These commands make it easy to perform database migrations, create controllers and models, and more.

For example, you can view all the commands provided by Artisan by entering the following command at the command line prompt:

php artisan list

The output will be similar to the following:

Available commands:
  clear-compiled      Remove the compiled class file
  db:seed             Seed the database with records
  help                Displays help for a command
  list                Lists commands
  migrate             Run the database migrations
  ......

You The corresponding command can be executed through "php artisan command".

Generate Controller

Use Laravel Artisan to quickly create a controller. With the following command, you can create a controller named "UserController":

php artisan make:controller UserController

After executing the above command, Laravel will automatically generate a UserController.php file and place it in the app/Http/Controllers directory. The controller will contain an empty class where you can add your own logic code.

At the same time, using Laravel Artisan can also generate RESTful API style controllers. For example, with the following command, you can create a controller that contains 7 RESTful methods (index, create, store, show, edit, update, destroy):

php artisan make:controller UserController --resource

Generate model

Laravel Artisan can also generate models for you. Using the following command, you can create a model named "User" in the app directory:

php artisan make:model User

After executing the above command, Laravel will automatically generate a User.php file and place it in the app directory. You can add properties and methods in this file to define the User model.

Generate Migrations

Laravel Artisan can also generate migrations for you. Using the following command, you can create a migration for the User model:

php artisan make:migration create_users_table

The above command will generate a migration file named "xxxx_xx_xx_xxxxxx_create_users_table" in the database/migrations directory.

In the migration file, you can define the structure and fields of the User table. For example:

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

The above code will create fields such as id, name, email, email_verified_at, password, remember_token, created_at and updated_at in the User table.

Finally, execute the following command to apply the migration to the database:

php artisan migrate

Generate template

In addition to controller, model, migration and other codes, Laravel Artisan can also Blade templates are generated for you. For example, use the following command to create a template named "welcome":

php artisan make:view welcome

After executing the above command, Laravel will automatically generate a template file named "welcome.blade.php" and place it in In the resources/views directory.

Summary

With Laravel Artisan, you can quickly generate code for controllers, models, migrations, templates, etc. This not only improves development efficiency, but also keeps the code style unified. Of course, you can also modify the default configuration to meet your needs.

However, it should be noted that Laravel Artisan is just a tool and it does not replace your development experience and skills. Good programming habits and deep technical skills are necessary conditions for becoming an excellent developer.
