To copy a column data from one table to another using migration in Bagisto you can follow these steps:
Step 1: Generate a new migration Open your terminal and navigate to your Bagisto application directory. Use the following command to generate a new migration file:
|
1 |
php artisan make:migration copy_column_data |
Step 2: Define the migration
Open the generated migration file (located in database/migrations) using a text editor. In this example, let’s assume the source table is called users and the column you want to copy is email. The new table will be called new_table, and it will also have an email column.

<?php use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; use Illuminate\Support\Facades\Schema; return new class extends Migration { /** * Run the migrations. * * @return void */ public function up() { // Retrieve data from the source table $data = DB::table('users')->pluck('email'); // Create the new table Schema::create('new_table', function (Blueprint $table) { $table->string('email'); $table->timestamps(); }); // Insert data into the new table foreach ($data as $email) { DB::table('new_table')->insert(['email' => $email]); } } /** * Reverse the migrations. * * @return void */ public function down() { // Drop the new table to rollback the migration Schema::dropIfExists('new_table'); } }; |
Step 3: Run the migration
Save the migration file and return to your terminal. Execute the following command to run the migration and apply the changes to the database:
|
1 |
php artisan migrate |
Bagisto will execute the up method of the migration, which retrieves the email data from the users table, creates the new_table, and inserts the data into the new table.
Congratulations! You have successfully copied the email column data from the users table to the new_table using a migration in Bagisto.
Additional Notes:
1. Make sure your Bagisto application is properly configured to connect to your database. You can check the .env file for the database configuration settings.
2. Modify the migration code according to your specific column names, table names, and database requirements.
3. If you need to rollback the migration and remove the new_table, you can use the following command:
|
1 |
php artisan migrate:rollback |
This will execute the down method of the migration, which drops the new_table.
Please note that Bagisto’s database structure may vary based on your specific application and any customizations you have made. Make sure to adapt the code and instructions based on your specific needs.
