    <p>I'm working on a CakePHP 1.2 application. I have a model "User" defined with a few HABTM relationships with other tables through a join table.</p> <p>I'm now tasked with finding User information based on the data stored in one of these HABTM tables. Unfortunately, when the query executes, my condition is rejected with an error about a missing table. Upon inspection it seems that CakePHP is not including any of the HABTM tables in the select statement.</p> <p>My User HABTM relationship is as follows:</p> <pre><code> var $hasAndBelongsToMany = array( 'Course' =&gt; array( 'className' =&gt; 'Course', 'joinTable' =&gt; 'course_members', 'foreignKey' =&gt; 'user_id', 'associationForeignKey' =&gt; 'course_id', 'conditions' =&gt; '', 'order' =&gt; '', 'limit' =&gt; '', 'uniq' =&gt; false, 'finderQuery' =&gt; '', 'deleteQuery' =&gt; '', 'insertQuery' =&gt; '' ), 'School' =&gt; array( 'className' =&gt; 'School', 'joinTable' =&gt; 'school_members', 'foreignKey' =&gt; 'user_id', 'associationForeignKey' =&gt; 'school_id', 'conditions' =&gt; '', 'order' =&gt; '', 'limit' =&gt; '', 'uniq' =&gt; false, 'finderQuery' =&gt; '', 'deleteQuery' =&gt; '', 'insertQuery' =&gt; '' ), 'Team' =&gt; array( 'className' =&gt; 'Team', 'joinTable' =&gt; 'team_members', 'foreignKey' =&gt; 'user_id', 'associationForeignKey' =&gt; 'team_id', 'conditions' =&gt; '', 'order' =&gt; '', 'limit' =&gt; '', 'uniq' =&gt; false, 'finderQuery' =&gt; '', 'deleteQuery' =&gt; '', 'insertQuery' =&gt; '' ) ); </code></pre> <p>The error is:</p> <blockquote> <p>SQL Error: 1054: Unknown column 'School.name' in 'where clause'</p> </blockquote> <p>And finally, the query it is trying to execute</p> <pre><code> SELECT `User`.`id`, `User`.`username`, `User`.`password`, `User`.`firstName`, `User`.`lastName`, `User`.`email `, `User`.`phone`, `User`.`streetAddress`, `User`.`city`, `User`.`province`, `User`.`country`, `User `.`postal`, `User`.`userlevel`, `User`.`modified`, `User`.`created`, `User`.`deleted`, `User`.`deleted_date ` FROM `users` AS `User` WHERE `User`.`id` = 6 AND `School`.`name` LIKE '%Test%' LIMIT 1 </code></pre>

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.
