Re: How to show different text in a view depending on the has_many association

hello,
if i understand your view display several posts
if your jointable is named fav_posts_users for exemple
you should have in your post model :
var $hasAndBelongsToMany = array(
'Favorite' => array(
'className' => 'User',
'joinTable' => 'fav_posts_users',
'foreignKey' => 'post_id',
'associationForeignKey' => 'user_id',
'unique' => true
),
);
in your user model :
var $hasAndBelongsToMany = array(
'Favorite' => array(
'className' => 'Post',
'joinTable' => 'fav_posts_users',
'foreignKey' => 'user_id',
'associationForeignKey' => 'post_id',
'unique' => true
),
);

and in your view :

foreach ($posts as $post):
if ($this->Session->check(Auth.User)):
// Loop through the posts favorites
foreach($post['Favorite'] as $favorite):
if ($favorite['user_id'] == $this->Session-
>read('Auth.User.id')):
/***** ITS YOUR FAVORITE!!!! *****/
else:
/*** BUTTON TO ADD TO FAVORITES ***/
endif;
endforeach;
else:
/*** BUTTON TO ADD TO FAVORITES ***/
endif;
endforeach;
