    text
    copied!<p>I have the following tables: binders, docs, users, docs_users. Doc belongsTo Binder, Doc hasAndBelongsToMany User. </p> <p>I want to get binders and their associated docs for the user that is currently logged in (the associated user_id in the docs_users table).</p> <p>I have tried Containable and find('all') with joins, conditions, etc. but I can't figure out how to remove the Docs that are from Users who are not associated in the docs_users table.</p> <p>This code does NOT work:</p> <pre><code>$binders = $this-&gt;Binder-&gt;find( 'all', array( 'joins' =&gt; array( array( 'table' =&gt; 'binders_users', 'alias' =&gt; 'BindersUser', 'type' =&gt; 'inner', 'foreignKey' =&gt; false, 'conditions'=&gt; array( 'BindersUser.binder_id = Binder.id', 'BindersUser.user_id = ' . $this-&gt;Auth-&gt;user('id') ) ), array( 'table' =&gt; 'docs', 'alias' =&gt; 'Doc', 'type' =&gt; 'left', 'foreignKey' =&gt; false, 'conditions'=&gt; array( 'Doc.binder_id = Binder.id', ) ), array( 'table' =&gt; 'docs_users', 'alias' =&gt; 'DocsUser', 'type' =&gt; 'left', 'foreignKey' =&gt; false, 'conditions'=&gt; array( 'DocsUser.doc_id = Doc.id', 'DocsUser.user_id = ' . $this-&gt;Auth-&gt;user('id') ) ) ), 'recursive'=&gt;0 ) ); $this-&gt;set('binders', $binders); </code></pre> <p>And neither does this:</p> <pre><code>$this-&gt;Binder-&gt;recursive = 2; $this-&gt;Binder-&gt;Behaviors-&gt;attach('Containable'); $this-&gt;Binder-&gt;contain(array( 'Branch', 'Doc' =&gt; array( 'User' =&gt; array( 'DocsUser' =&gt; array( 'conditions' =&gt; array('id = "17"') ) ) ) )); $binders = $this-&gt;Binder-&gt;find('all'); </code></pre> <p>Any help from you seasoned pros would be great! Thanks!</p> <p><strong>Alternative/Simplified Solutions?</strong></p> <p>This works if I just want to get binders to which users have permissions. Short and sweet. However, it will still send ALL associated docs through, which is NOT the behavior I want. It needs to only pass on the docs to which the user has permissions (as described previously).</p> <pre><code>$binders = $this-&gt;Binder-&gt;find( 'all', array( 'joins' =&gt; array( array( 'table' =&gt; 'binders_users', 'alias' =&gt; 'BindersUser', 'type' =&gt; 'inner', 'foreignKey' =&gt; false, 'conditions'=&gt; array( 'BindersUser.binder_id = Binder.id', 'BindersUser.user_id = ' . $this-&gt;Auth-&gt;user('id') ) ) ) ) ); </code></pre>
