[Plugin: WP MVC] Accessing other Models from a controller

It appears that something like:

$event = new Event();

$allEvents = $event->find();

will work, is this supported, or does the framework do some biolerplate setup?

You’ll want to use the load_model() or load_models() methods for this; here’s how to use it:
https://wpmvc.org/documentation/91/load_model/
https://wpmvc.org/documentation/92/load_models/

(Sorry, I had somehow overlooked including these in the documentation, but they’re in there now.)

Thanks Tom,

Looks good

I’m trying to have one model’s admin page show field values from an associated model. Just a column that converts the id to the correct name from the associated table. Using the events-calendar-example as a reference did not make it obvious how to do this “simple” task. I didn’t find any direct means to reference the associated table’s fields in the default_fields list. Instead, I had to create an access function referenced via value_method that just dereferences the object to pull out the correct name field from the associated table’s object reference.

It would be great if there were a direct way to refer to the associated table’s fields in the default list. Maybe something like ‘Venue.name’ or ‘venues.name’.

I’m looking for something similar… Could you share the fix you made?

@summergrand
value_method it is for me too!

Apparently the function that displays admin table cells goes like this:

public function admin_table_cell($controller, $object, $column) {
   if (!empty($column['value_method'])) {
      $value = $controller->{$column['value_method']}($object);
   } else {
      $value = $object->$column['key'];
   }
   return '<td>'.$value.'</td>';
}

wp-content\plugins\wp-mvc\core\helpers\mvc_helper.php line 188

Doesn’t seem to include any processing of this kind ??

Here is a little patch that would allow to reference a sub object in the format ‘Venue.name’

wp-content\plugins\wp-mvc\core\helpers\mvc_helper.php line 188

public function admin_table_cell($controller, $object, $column) {
   if (!empty($column['value_method'])) {
      $value = $controller->{$column['value_method']}($object);
   } else {
      $subs = explode('.', $column['key']);
      foreach ($subs as $sub)
         $object = $object->$sub;
      $value = $object;
   }
   return '<td>'.$value.'</td>';
}

You could also patch the header cell function line 171 for the name to display automatically:

public function admin_header_cell($label) {
   return '<th scope="col" class="manage-column">'.MvcInflector::titleize(str_replace('.', ' ', $label)).'</th>';
}
