What is the MySQL datatype SET equivalent in Laravel Schema?

Question

Laravel Schema has a command for ENUM equivalent to the table. What is the SET equivalent to the table?

Answer 1

Step 1. Extend default classes(add this code to your migration file after use sections):

class ExtendedBlueprint extends Blueprint {

    /**
     * Create a new set column on the table.
     *
     * @param  string  $column
     * @param  array   $allowed
     * @return \Illuminate\Support\Fluent
     */
    public function set($column, array $allowed)
    {
        return $this->addColumn('set', $column, compact('allowed'));
    }

}


class ExtendedMySqlGrammar extends Illuminate\Database\Schema\Grammars\MySqlGrammar {

    /**
     * Create the column definition for an set type.
     *
     * @param  \Illuminate\Support\Fluent  $column
     * @return string
     */
    protected function typeSet(\Illuminate\Support\Fluent $column)
    {
        return "set('".implode("', '", $column->allowed)."')";
    }

}

Step 2. Then, we need to change default grammar and blueprint classes to our custom:

// set new grammar class
DB::connection()->setSchemaGrammar(new ExtendedMySqlGrammar());

// get custom schema object
$schema = DB::connection()->getSchemaBuilder();

// bind new blueprint class
$schema->blueprintResolver(function($table, $callback) {
    return new ExtendedBlueprint($table, $callback);
});

// then create tables 
$schema->create('table name', function(ExtendedBlueprint $table)
{
    $table->increments('id');
    $table->text('sentence');
    $table->string('author')->nullable();
    $table->string('source')->nullable();
    $table->set('difficulty', range(1, 10)); // use our new mysql type 
    $table->boolean('enabled')->default(true);
});

This method will also work after composer update, because we did not edited any framework code.
