Laravel 5.1 : Migrate existing database - laravel

Question

https://github.com/Xethron/migrations-generator
I migrated my database structure into Laravel using php artisan migrate:generate command with the help of the extension above. But there's a small problem, my primary key's aren't named as id, I rather used a different convention by adding a prefix for each of them like user_id, product_id, photo_id, etc. All of these are auto incremented, of course.
Here's my current create_users_table.php file inside my migrations folder. I defined user_id to override the default id option, is that the correct use?
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->primary('user_id');
$table->integer('user_id', true);
$table->string('name', 500);
$table->string('email', 500);
$table->string('password', 500);
}
);
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::drop('users');
}
}
I read that I need to add something like below, but I'm not sure where to define protected $primaryKey since my class extends Migration rather than Eloquent.
class CreateUsersTable extends Eloquent {
protected $primaryKey = 'user_id';
}
I'm getting the following error when I go to /auth/login page, which I think causes because of the user_id usage rather than id. How can I fix it?
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'users.id' in 'where clause' (SQL: select * from `users` where `users`.`id` = 5 limit 1)

You need to specify your non-default primary key in your User model:
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model {
protected $primaryKey = 'user_id';
You will need to do this for all Models that don't use id as their primary key.
