Laravel seed table from multiple csv files - sql

Question

I'm very new to Laravel and Database and I'm trying to understand how to insert data into my database. Please be patient the question can sounds dummy for you.
STEP
I created a table in migrations. Example of a table:
public function up(){
Schema::create('job-urls', function (Blueprint $table) {
$table->increments('id');
$table->foreign('job_id')->references('id')->on('jobs');
$table->string('url')->index();
$table->string('hash');
$table->timestamp('created_at')->nullable();
$table->timestamp('updated_at')->nullable();
STEP
I have two csv file that correspond to the field url and hash and I want to insert them. I created a new file in migration called populate_jobs_url
class PopulateJoburls extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up(){
$fileurls = fopen('../data/urls.csv', 'r');
$filehash = fopen('../data/urls_hash.csv', 'r');
while (($row = fgetcsv($fileurls, 0, ',')) !=FALSE){
DB::table('joburls')->insert(
array(
'url' => $row,
)
);
}
while (($row = fgetcsv($filehash, 0, ',')) !=FALSE){
DB::table('joburls')->insert(
array(
'hash' => $row,
)
);
}
}
Can you help me to understand how I check if the table is correctly filled? Is this approach correct? How could I insert data otherwise in my Database? Unfortunately all examples on the web deal with inserting manually data with a form.
Thanks

Seeding the table inside of a migration file is not the best practise. You can take advantage of Seeders, which is right way to fill your table with test or actual data.
First, create a seeder file with php artisan make:seeder PopulateJobUrls command. Then you can arrange your seeder like this:
<?php
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
class PopulateJobUrls extends Seeder
{
/**
* Run the database seeds.
*
* #return void
*/
public function run()
{
$fileurls = fopen('../data/urls.csv', 'r');
$filehash = fopen('../data/urls_hash.csv', 'r');
// Rest of your seeding logic...
}
}
You should reference your seeder from database/seeds/DatabaseSeeder.php in the run method:
$this->call(PopulateJobUrls::class);
Run php artisan db:seed or if you want to be more specific, php artisan db:seed --class=PopulateJobUrls and you are good to go with your correctly filled data!
