In this short snippet, you will learn how to populate records from within the Laravel database migration file. For this scenario imagine wanting to add some records for the posts table. To do that you can write your code like below.
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreatePostsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->timestamps();
});
$posts = [
['title' => 'Hello John'],
['title' => 'Hello Jane'],
['title' => 'Hello Bob']
];
foreach ($posts as $postData){
$post = new \App\Models\Post(); /* The Post is the model for your migration */
$post->title = $postData['title'];
$post->save();
}
/* do note that the created_at and updated_at is automatically added */
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('posts');
}
}It's important to have the schema definition first and then only have the data looped to insert into the database.
<?php
Schema::create('posts', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->timestamps();
});In this case, we are inserting the data by using the Eloquent model itself.
<?php
$posts = [
['title' => 'Hello John'],
['title' => 'Hello Jane'],
['title' => 'Hello Bob']
];
foreach ($posts as $postData){
$post = new \App\Models\Post(); /* The Post is the model for your migration */
$post->title = $postData['title'];
$post->save();
}
/* do note that the created_at and updated_at is automatically added */
