laravel errno 150 foreign key constraint is incorrectly formed

Question

Can anybody help me to solve this problem?

There are 3 tables with 2 foreign keys:

Schema::create(\'users\', function (Blueprint $table) {
    $table-&         


        

Answer 1

we are table villes:

Schema::create('villes', function (Blueprint $table) {
            $table->bigIncrements('idVille'); // bigIncrement(8 bits)
            $table->string('nomVille');
            $table->timestamps();
        });

foreign key in table users for exemple :

Schema::table('users', function (Blueprint $table) {
            $table->bigInteger('ville_idVille')->unsigned()->after('tele');
            $table->foreign('ville_idVille')->references('idVille')->on('villes');
        });
