Laravel Migration is not creating the table in different database - laravel

Question

I have this migration file:
<?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()
{
Schema::connection('DB1')->create('feed_mappings', function (Blueprint $table) {
$table->bigIncrements('id_feed')->autoIncrement();
$table->string('id_project', 255);
$table->string('import_field_slug', 155);
$table->string('internal_field_slug', 155);
$table->tinyInteger('import');
$table->tinyInteger('custom_field')->default(0);
$table->dateTime('date_add');
$table->dateTime('date_upd');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('feed_mappings');
}
};
And I have this config in the database.php file:
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
'DB1' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '8889'),
'database' => env('DB_DATABASE', 'DB1'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'root'),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
Now, I have run this command :
php artisan migrate:refresh --seed
Now, All the migration file is creating a tables on default database but I want this feed_mappings should go to DB1 database.
BUT this feed_mapping is not going to DB1 database. Can you tell me why?

Answer 1

So the issue is in your database.php file where you are using the same variables for connections 1 and 2
'mysql' => [
'driver' => 'mysql',
***'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),***
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
'DB1' => [
'driver' => 'mysql',
**'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '8889'),
'database' => env('DB_DATABASE', 'DB1'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'root'),**
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
what you need to do is create separate variables for db connections e.g:
DB_HOST // for connection 1
DB_HOST_2 // for connection 2
and use these in your config files for more info visit: https://codelapan.com/post/how-to-use-multiple-database-connections-in-laravel-8

config/database.php

]) : [],
],
'mysql2' => [

Setup .env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_multiple_database1
DB_USERNAME=root
DB_PASSWORD=
DB_CONNECTION_2=mysql
DB_HOST_2=127.0.0.1
DB_PORT_2=3306
DB_DATABASE_2=laravel_multiple_database2
DB_USERNAME_2=root
DB_PASSWORD_2=
in Model example Post
protected $connection = 'mysql2';
in migration file
public function up()
{
Schema::connection('mysql2')->create('posts', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->timestamps();
});
}
public function down()
{
Schema::connection('mysql2')->dropIfExists('posts');
}
