I am trying to migrate my newly created migrations. The problem is that the batch of migrations waiting to migrate is in the order in which I created the migrations using
php artisan make:migration
And thus, my product_list
migration is trying to set a foreign key on a table that it has not yet migrated.
$table->foreign('product_category')->references('id')->on('product_categories');
$table->foreign('product_type')->references('id')->on('product_types')->onDelete('cascade');
When I run php artisan migrate
I get these errors:
C:\xampp\htdocs\iezonsolutions>php artisan migrate
Migrating: 2019_01_15_001617_product_list
Illuminate\Database\QueryException : SQLSTATE[HY000]: General error: 1005 Can't create table `iezonsolutions`.`#sql-1844_16e` (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: alter table `product_list` add constraint `product_list_product_category_foreign` foreign key (`product_category`) references `product_categories` (`id`))

Is it possible to migrate my product_category
and product_types
tables before my product_list
table? Then I will be able to set the foreign keys without errors.
My migration status looks like this:
+------+------------------------------------------------+-------+
| Ran? | Migration | Batch |
+------+------------------------------------------------+-------+
| Yes | 2014_10_12_000000_create_users_table | 1 |
| Yes | 2014_10_12_100000_create_password_resets_table | 1 |

I want it to migrate in the order
| No | 2019_01_15_002336_product_categories | |
| No | 2019_01_15_002318_product_types | |

| No | 2019_01_15_002357_product_skus | |

The simplest thing you can do is order the date and time on filename which eventually followed by laravel to migrate database sequentially.
