    <p>I do not understand how to implement a many to many relation in CActiveDataProvider.</p> <p>At first the situation, I have one Model "Company" with following relations:</p> <pre><code>return array( 'owner' =&gt; array(self::HAS_ONE, 'User', 'user_id'), 'admins' =&gt; array(self::MANY_MANY, 'User', '{{company_user}}(company_id,user_id)', 'condition' =&gt; 'is_admin = 1'), 'members' =&gt; array(self::MANY_MANY, 'User', '{{company_user}}(company_id,user_id)'), 'standard_members' =&gt; array(self::MANY_MANY, 'User', '{{company_user}}(company_id,user_id)', 'condition' =&gt; 'is_admin = 0'), ); </code></pre> <p>Now I want to get all admins of a company. Normally I did:</p> <pre><code>$company = Company::model()-&gt;find('company_id=1'); var_dump($company-&gt;with('admins')-&gt;findAll()); </code></pre> <p>So I have all administrators of a company.</p> <p>But I did not parse, how to do it with a CActiveDataProvider.</p> <pre><code>$dataProvider_admins = new CActiveDataProvider('Company', array( 'criteria' =&gt; array( 'with' =&gt; array( 'admins' =&gt; array('condition' =&gt; 'company_id='.$company-&gt;id) ), ), 'pagination' =&gt; array( 'pageSize' =&gt; 20, ), )); var_dump($dataProvider_admins-&gt;getData()); </code></pre> <p>But with this way I get a company record with all administrators, but not an array containing all administrators.</p> <p>Update: I could create an Model for the relation table <code>{{company_user}}</code> and use this, but I do not think its the right way, isn't it?</p>

    1. COput `array('condition' => 'company_id='.$company->id)` before `'with'` and keep only `'with' => array('admins')`

    2. COGood advice, but the result is **one** company entry and not an array of administrators entries. The problem is the widget, which i am using will display the one company entry and not a list of administrators.

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.
