Laravel create simple relationship for 2 table from single table - laravel

Question

I have 3 models: User , ChangeMoney and CurrencyType, I have simple relationship with User and ChangeMoney and I want to add another relationship with ChangeMoney table with CurrencyType, but I get this error:
D:\xampp\htdocs\epay-pro>php artisan migrate
[Illuminate\Database\QueryException]
SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint (SQL
: alter table `change_money` add constraint change_money_currency_id_foreig
n foreign key (`currency_id`) references `currency_type` (`id`))
current my migration is:
Schema::create('change_money',function(Blueprint $table){
$table->increments('id');
$table->tinyInteger('currency_type');
$table->string('current_money');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->integer('currency');
$table->timestamps();
});
and I don't have any problem, now I want to add other foreign key to CurrencyType table such as:
Schema::create('change_money',function(Blueprint $table){
$table->increments('id');
$table->tinyInteger('currency_type');
$table->string('current_money');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->integer('currency_id')->unsigned();
$table->foreign('currency_id')->references('id')->on('currency_type');
$table->timestamps();
});
currency_type table migration:
Schema::create('currency_type',function(Blueprint $table){
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->string('currency_type','50');
$table->char('currency_symbol','1');
$table->timestamps();
});

Answer 1

Migrations in Laravel runs in order. I don't now your migrations order, but I think that your change_money migration is running first than your currency_type migration. So when the aplication try to add a foreign key in ChangeMoney table to CurrencyType table, the CurrencyType table not exist yet.
Try to create a new migration to add just the relationship between ChangeMoney table and CurrencyType table

Answer 2

You have to remove data from both tables ('change_money', 'currency_type').
Or you can turn off the check of foreign keys. In MySQL, or in the phpmyadmin run this:
SET FOREIGN_KEY_CHECKS=0;
Run migration in Laravel: php artisan migrate
And then again turn on check of foreign keys:
SET FOREIGN_KEY_CHECKS=1;

PROBLEM SOLVED by split foreign key to other migration
class ForeignKeyBetweenChangeMoneyAndCurrencyType extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::table('change_money', function (Blueprint $table) {
$table->integer('currency_id')->unsigned();
$table->foreign('currency_id')->references('id')->on('currency_type');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::table('change_money', function(Blueprint $table) {
$table->dropForeign(' change_money_currency_id_foreign');
});
}
}
