Laravel 7.4 cannot add foreign key constraint - mysql

Question

So I'm creating a migration file following the template of my old one as follows:
create_banners_table (this one WORKED)
class CreateBannersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('banners', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('order');
$table->string('published');
$table->timestamps();
});
Schema::create('banner_translations', function (Blueprint $table) {
$table->increments('id')->unsigned();
$table->string('locale', 10)->index();
$table->string('title');
$table->string('url');
$table->foreignId('banner_id')
->constrained()
->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('banner_translations');
Schema::dropIfExists('banners');
}
}
Here's the create_managements_table (this one FAILED):
class CreateManagementsTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('managements', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('order');
$table->string('published');
$table->string('name');
$table->string('category')
->comment('board of commissioners', 'board of executives');
$table->timestamps();
});
Schema::create('management_translations', function (Blueprint $table) {
$table->increments('id')->unsigned();
$table->string('locale', 10)->index();
$table->string('description');
$table->string('title');
$table->foreignId('management_id')
->constrained()
->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('management_translations');
Schema::dropIfExists('managements');
}
}
The problem is, when I tried to make another migration file based on that, I got this error:
SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint (SQL: alter table `management_translations` add constraint `management_translations_management_id_foreign` foreign key (`management_id`) references `management` (`id`) on delete cascade)
As you can see both of the translation table references the big integer in their respective base table (so there is no type mismatch).
For further investigation, I ran SHOW ENGINE INNODB STATUS;
and checked the Latest Foreign Key Error and got the following:

Answer 1

Whether or not the word management countable is ambiguous so apparently Laravel treats it as uncountable in this case. That's to say that Laravel thinks the corresponding table name for management_id would be management not managements which is an uncommon plural form. Therefore you either should rename your base table to management or use the following foreign key sytnax:
Schema::create('management_translations', function (Blueprint $table) {
$table->increments('id')->unsigned();
$table->string('locale', 10)->index();
$table->string('description');
$table->string('title');
$table->foreignId('management_id')
->constrained('managements')
->onDelete('cascade');
});

Answer 2

Schema::create('banner_translations', function (Blueprint $table) {
$table->increments('banner_id')->unsigned(); //change this line
$table->string('locale', 10)->index();
$table->string('title');
$table->string('url');
$table->foreignId('banner_id')
->constrained()
->onDelete('cascade');
});
I think you should provide banner_id first and then provide foreignId.(same column name)

Answer 3

you can add foreign key reference as like below,
first create all the keys then at last declare the foreign key reference ... you can see this method at Laravel Doc's ... See First example of that link
Schema::create('managements', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('order');
$table->string('published');
$table->string('name');
$table->string('category')
->comment('board of commissioners','board of executives');
$table->timestamps();
});
Schema::create('management_translations', function (Blueprint $table) {
$table->increments('id')->unsigned();
$table->string('locale', 10)->index();
$table->string('description');
$table->string('title');
$table->unsignedBigInteger('management_id');
$table->foreign('management_id')
->references('id')
->on('managements');
->onDelete('cascade');
});
If you face any error using my solution let me know, I will update my answer
Thank you
