Laravel 4 - 选择相关型号

I have following table

Schema::create('jokes_categories', function(Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('is_active');
    $table->timestamps();
});

Schema::create('jokes', function(Blueprint $table) {
    $table->increments('id');
    $table->string('content', 200)->unique();;
    $table->enum('is_active', array('Y', 'N'));
    $table->integer('category_id')->unsigned();
    $table->foreign('category_id')->references('id')->on('jokes_categories');
    $table->timestamps();
});

In the jokes table category_id is a foreign key and it has a one-to-many relationship with jokes_categories

In the model I have the following:

class Joke extends \Eloquent {

    public static $rules = array();

    // Don't forget to fill this array
    protected $fillable = array();

    public function JokesCategory(){
         return $this->belongsTo('JokesCategory');
    }
}

In the controller I have the following:

$jokes = Joke::all();

But it does not pull through joke_categories.name (I was under the impression that the model definition will directly help to pull related models)

What could be the solution?

    Your query is just on the Joke table.

    You could eagerload the categories ie.

    $jokes = Joke::with('JokesCategory')->get();
    

    See docs: http://laravel.com/docs/eloquent#eager-loading
