Re: TreeBehavior fails to set lft and rght correctly

Also, these two suggestions were in the comments.  I didn't need the relationship from the first one but I am using the latest svn checkout, so perhaps he was posting that from an older version.  Also the second one might be useful as well.

The model needs a relation for me to work with this example.

If I add the following to the model it works:

<pre>

var $belongsTo = array(

'Parent' =&gt; array(

'className' =&gt; 'Category',

'foreignKey' =&gt; 'parent_id',

'conditions' =&gt; '',

'fields' =&gt; '',

'order' =&gt; '',

'counterCache' =&gt; ''),

);

</pre>

I just spent a lot of time troubleshooting an odd issue. Make sure your id, lft and rght columns are set to just UNSIGNED and not UNSIGNED ZEROFILL. I like to use the ZEROFILL attribute on all my integer column types that store id values but the TreeBehavior fails without any warnings or errors if the integer column values are in the format of 00000001 instead of just 1.

Can you paste your model?  Or at least the important parts at the top?

Hi everyone,

I'm using TreeBehavior in a classic model, but its lft and rght fields
are not set correctly.


I tried these two save() in a controller  :

               $this->MenuItem->create();
               $this->MenuItem->save(array('MenuItem' => array(
                       'url' => '/fre',
                       'parent_id' => null,
                       'label' => 'Home',
                       'online' => 1
                       )));
               $parent_id = $this->MenuItem->id;
               debug($this->MenuItem->verify());

               $this->MenuItem->create();
               $this->MenuItem->save(array('MenuItem' => array(
                       'url' => '/fre/p/Choses',
                       'parent_id' => $parent_id,
                       'label' => 'Choses',
                       'online' => 1
                       )));

               debug($this->MenuItem->verify());

               debug($this->MenuItem->recover());

               debug($this->MenuItem->verify());

               die();

I truncated the table menu_items, ran the test and discovered that the
two last calls to verify() fail, even after recover().

I followed the cookbook... but did I miss something?

If it can helps :
I'm running Cake 1.2.3.8166
I also tried to download the last TreeBehavior from cake's master
branch, but it didn't change anything

thanks!
