How to access entity method?

That's because find() doesn't find anything. You need to pass the id as parameter:

PHP Code:

    public function view( $user_id=false )
    {
        $model = model('UserModel');
        $user = $model->find($user_id);
        d($user->name);
    } 


Thanks for your answer but still wont work, I get this:

Code:

$user->name null
