Thanks Martin!
So i can put the method in the model class, but how would I call it
within a view?
This is the link I have that calls the ingredients function to remove
it from the group. If I put the method in the model, I can't call it
directly like I'm doing below can I?
Right now this works, but I'm open to a better way:
<?php echo $html->link(__('Remove', true),
array('controller'=>'ingredients',
'action'=>'removeFromGroup',
$ingredient['id'],
$ingredientGroup
['IngredientGroup']['id']),
null, sprintf(__('Are you sure you want to
remove \'%s\' from this group?', true), $ingredient['name'])); ?>
Can I just put
$this->IngredientGroup->Ingredient->removeFromGroup( $ingredient
['id'], $ingredientGroup['IngredientGroup']['id'])
directly in the view somehow? That seems to go away from the MVC
methodology.
Thanks again!
