Installation

To use this extension, just copy this file to your extensions/ directory, add 'import' => 'application.extensions.CAdvancedArBehavior', [...] to your config/main.php and add this behavior to each model you would like to inherit the new possibilities.

Usage
public function behaviors(){
          return array( 'CAdvancedArBehavior' => array(
            'class' => 'application.extensions.CAdvancedArBehavior'));
          }
Possibilities so far:
Better support of MANY_TO_MANY relations:

When we have defined a MANY_MANY relation in our relations() function, we are now able to add up instances of the foreign Model on the fly while saving our Model to the Database. Let´s assume the following Relation:

Post has: 'categories'=>array(self::MANY_MANY, 'Category',

              'tbl_post_category(post_id, category_id)')

Category has: 'posts'=>array(self::MANY_MANY, 'Post',

              'tbl_post_category(category_id, post_id)')

Now we can use the attribute 'categories' of our Post model to add up new rows to our MANY_MANY connection Table:

$post = new Post();
$post->categories = Category::model()->findAll();
$post->save();

This will save our new Post in the table Post, and in addition to this it updates our N:M-Table with every Category available in the Database.

We can further limit the Objects given to the attribute, and can also go the other Way around:

 $category = new Category();
 $category->posts = array(5, 6, 7, 10);
 $category->save();

We can pass Object instances like in the first example, or a list of integers that representates the Primary key of the Foreign Table, so that the Posts with the id 5, 6, 7 and 10 get´s added up to our new Category.

5 Queries will be performed here, one for the Category-Model and four for the N:M-Table tbl_post_category. Note that this behavior could be tuned further in the future, so only one query get´s executed for the MANY_MANY Table.

We can also pass a single object or an single integer:

 $category = new Category();
 $category->posts = Post::model()->findByPk(12);
 $category->posts = 12;
 $category->save();
