Foreign key constraint is incorrectly formed with Composite Keys - laravel

Question

I have a table "theaters". In which (theater_name,area_name,station) are composite key.And in the table "cubelists" I have columns (thtr_name,area,stn) which are to be referred to (theater_name,area_name,station) of table "theaters".
The problem here is the combination of the columns - (theater_name,area_name,station) in table "theaters" is unique as it is a composite key. But each column separately is not unique.
Then how can I refer these columns from table "cubelists"?
Schema::create('theaters', function (Blueprint $table) {
$table->string('theater_name');
$table->string('area_name');
$table->string('station');
$table->primary(array('theater_name','area_name','station'));
$table->text('address');
$table->bigInteger('phno');
$table->string('contact_person');
});
public function up()
{
//
Schema::create('cubelists', function (Blueprint $table) {
$table->string('mvie_name');
$table->foreign('mvie_name')->references('movie_name')->on('movies');
$table->string('thtr_name');
$table->string('area');
$table->string('stn');
$table->foreign(array('thtr_name','area','stn'))-
>references(array('theater_name','area_name','station'))-
>on('theaters');
$table->primary(array('mvie_name','thtr_name','area','stn'));
$table->string('type');
$table->string('subtype');
$table->date('validity');
$table->string('show');
});
}
If I give the above code I get an error as
Migration table created successfully.
[Illuminate\Database\QueryException]

Answer 1

You must first create the table, then foreign keys.
Schema::create('cubelists', function (Blueprint $table) {
$table->string('mvie_name');
$table->string('area');
$table->string('stn');
$table->primary(array('mvie_name','thtr_name','area','stn'));
$table->string('type');
$table->string('subtype');
$table->date('validity');
$table->string('show');
$table->foreign(array('thtr_name','area','stn'))
->references(array('theater_name','area_name','station'))
->on('theaters');
$table->foreign('mvie_name')
->references('movie_name')
->on('movies');
});
Also theaters table must migrate first since cubelists is referencing it. And make sure that the foreign key column and the referencing column are the same type or length.
