OR
Schema::table('posts', function (Blueprint $table) {
$table->foreignId('user_id')->constrained();
});cannot add foreign key constraint laravel
Add it in two steps, and its good to make it unsigned too:
public function up()
{
Schema::create('priorities', function($table) {
$table->increments('id', true);
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->string('priority_name');
$table->smallInteger('rank');
$table->text('class');
$table->timestamps('timecreated');
});
}
if still same error try removing unsigned() from the above codeCopyright © 2021 Codeinu
