    <p>I have created hasManyThrough table like below:</p> <p>id user_id friend_id</p> <p>I also have users table like below: id username password</p> <p>I want to have both user_id and friend_id belongsTo relation with user's id column. So I have written below two models:</p> <p>Friend model</p> <pre><code>class Friend extends AppModel { var $name = 'Friend'; //The Associations below have been created with all possible keys, those that are not needed can be removed var $belongsTo = array( 'User' =&gt; array( 'className' =&gt; 'User', 'foreignKey' =&gt; 'user_id', 'conditions' =&gt; '', 'fields' =&gt; '', 'order' =&gt; '' ), 'Friend' =&gt; array( 'className' =&gt; 'User', 'foreignKey' =&gt; 'friend_id', 'conditions' =&gt; '', 'fields' =&gt; '', 'order' =&gt; '' ) ); } </code></pre> <p>User model</p> <pre><code>class User extends AppModel { var $name = 'User'; var $displayField = 'username'; var $hasMany = array( 'User' =&gt; array( 'className' =&gt; 'Friend', 'foreignKey' =&gt; 'user_id', 'dependent' =&gt; false, 'conditions' =&gt; '', 'fields' =&gt; '', 'order' =&gt; '', 'limit' =&gt; '', 'offset' =&gt; '', 'exclusive' =&gt; '', 'finderQuery' =&gt; '', 'counterQuery' =&gt; '' ), 'Friend' =&gt; array( 'className' =&gt; 'Friend', 'foreignKey' =&gt; 'friend_id', 'dependent' =&gt; false, 'conditions' =&gt; '', 'fields' =&gt; '', 'order' =&gt; '', 'limit' =&gt; '', 'offset' =&gt; '', 'exclusive' =&gt; '', 'finderQuery' =&gt; '', 'counterQuery' =&gt; '' ) ); } </code></pre> <p>I'm not sure why but when I try to view this via controller in scaffolding, it comes up with 500 server error?? Is there something wrong with the model config that is creating wrong SQL?</p> <p>OK it seems like error is due to Zend Optimizer according to some forums. This is creating Segmentation Fault when baking!</p> <p>I cannot turn off this in the third party hosted server so I might have to move to my local server and test so I can see Cake errors.</p> <p>OK below is the error (it's very long so I'm not going to put all but below gives a bit of an idea):</p> <pre><code>Fatal error: Maximum function nesting level of '100' reached, aborting! in /usr/share/php/cake/libs/debugger.php on line 248 Call Stack: 0.0011 352048 1. {main}() </code></pre>

    1. CODon't look for the errors numbers. Check what an error is about.

    3. COOK found a reason why! I cannot use the association name same as related model name!! Changing Friend to Friends has solved the problem!

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.
