Well HATBM works in an very strange way. If you really need HATBM I would suggest NOT changing a model association, but using an interesting shorthand for saving additional data fields in the join table. I've encountered this a lot of times and this is the best solution: Actually, just for saving your additional fields you can unbind all HATBM relations and add a new hasMany binding "on the fly" pointing to the join model. Firstly you should unbind the existing HATBM relation. <pre><code>$this->Order->unbindModel(array('hasAndBelongsToMany' => array('Product'))); </code></pre> Then add a new "on-the-fly" hasMany binding: <pre><code>$this->Order->bindModel(array('hasMany' => array('OrdersPost'))); </code></pre> Then if your data is: <pre><code>$this->data['Order']['id'] = '1'; $this->data['OrdersPost'][0]['product_id'] = '15'; $this->data['PostsTag'][0]['price'] = '5000.00'; $this->data['PostsTag'][0]['quantity'] = '1'; $this->data['OrdersPost'][1]['product_id'] = '16'; $this->data['PostsTag'][1]['price'] = '4000.00'; $this->data['PostsTag'][1]['quantity'] = '2'; </code></pre> As mentioned above, HATBM always erases all existing records before inserting new ones. So maybe you should take care about that before you do: <pre><code>$this->Order->saveAll($this->data); </code></pre> This works when you dont want to change your datamodel, but still need additional functionality. Hope this helps. <a href="http://nuts-and-bolts-of-cakephp.com/2008/09/24/saving-extra-fields-in-the-join-table-for-habtm-models/" rel="nofollow">Original Solution and Credits HERE</a>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
