Database Operations and Model Associations with Laravel
Laravel is a modern and powerful PHP framework and is very effective and user-friendly when it comes to database operations. In this article, we will discuss in detail how to perform database operations and model associations in Laravel.
First, we use Migrations for database operations in Laravel. Migrations are used to create, modify, or delete database tables. For example, we can create a table by creating a Migration file like this:
php artisan make:migration create_users_table
Then, we define the columns of the table by editing the Migration file we created and migrate it to the database:
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamps();
});
Model associations are used to define relationships between database tables. For example, when we want to define a relationship between a "Posts" table and a "Users" table:
class Post extends Model {
public function user() {
return $this->belongsTo(User::class);
}
}
