Hi,
I am trying to understand the much discussed Cortex plugin. 
I am playing around with it a little bit but I am somewhat confused. 
I have a model 'User' and a controller, aptly named 'UserController'.
I have found out the possibility to use the fluid mode from the controller, this seems to be working, except that I think I found a bug: when the db table 'users' does not yet exist the program generates an error on the rights_level item. It does not appear to be accepting the underscore, without the underscore in the model it works.
    public function index()
    {
        $user->name="admin";
        $user->mail="te...@mail.inv";
        $user->website="www.google.com";
        $user->rights_level=1;
        $user->save();
        $user->reset();
        $this->f3->set('users',$user->all());
        $this->f3->set('view','list.htm');
    } My User model: 
class User extends \DB\Cortex {
  protected
    $fieldConf = array(
        'name' => array(
            'type' => 'VARCHAR256',
            'nullable' => false,
        ),
        'mail' => array(
            'type' => 'VARCHAR128'
        ),
        'website' => array(
            'type' => 'VARCHAR256'
        ),
        'rights_level' => array(
            'type' => 'TINYINT',
            'default' => 3,
        ),
    ),
    $db = 'DB',
    $table = 'users',
    $fluid = true,      // triggers the SQL Fluid Mode, default: false
    $primary = 'uid',   // name of the primary key (auto-created), default: id
    $ttl = 120,         // caching time of field schema, default: 60
    $rel_ttl = 30;      // caching time of all relations, default: 0
    
    public function all()
    {
        return $this->find();
    }
}
This is code I copied from the cortex manual on github. 
I do not understand how to set the $db in the model. If I sent it from the controller (as above) the model seems to be using that db and it does not take the one set as $db into account. 
I only need to set the $table, that is the only thing it seems to care about. 
If I don't send the db-connection in the controller it never gets set. How can I set the DB variable that is being used in the sample code?
This is likely also linked to the fact that I can not user $user::setup() to initialize the table.
