    <p>I have a model with 3 tables Many to 1 to many as below</p> <p>(shortened schema.yml)</p> <pre><code>PeerEngagement: columns: id: { type: integer(4), notnull: true, unique: true, primary: true, autoincrement: true } peer_id: { type: integer(4), notnull: true } relations: Peer: { local: peer_id, class: Person } Person: columns: id: { type: integer(4), notnull: true, unique: true, primary: true, autoincrement: true } nhi: { type: string(7) } name: { type: string(100), notnull: true } relations: Ethnicity: { class: Ethnicity, refClass: PersonEthnicity, local: person_id, foreign: ethnicity_id } PersonEthnicity: columns: id: { type: integer(4), notnull: true, unique: true, primary: true, autoincrement: true } person_id: { type: integer(4), notnull: true } ethnicity_id: { type: integer(4), notnull: true } relations: Person: class: Person local: person_id onDelete: CASCADE Ethnicity: class: Ethnicity local: ethnicity_id onDelete: RESTRICT Ethnicity: columns: id: { type: integer(4), notnull: true, unique: true, primary: true, autoincrement: true } name: { type: string(50) } </code></pre> <p>Saving these things in auto-generated forms is fine. However in a special case I need to save nhi and ethnicity separately from within PeerEngagementForm.</p> <p>For saving nhi i have working:</p> <pre><code>function doSave($con=null){ ... if(isset($this-&gt;values['nhi'])){ $this-&gt;getObject()-&gt;getPeer()-&gt;setNhi($this-&gt;values['nhi']); $this-&gt;getObject()-&gt;getPeer()-&gt;save(); } ... </code></pre> <p>but the same technique doesn't work with</p> <pre><code>if(isset($this-&gt;values['ethnicity_list'])){ $this-&gt;getObject()-&gt;getPeer()-&gt;setEthnicity($this-&gt;values['ethnicity_list']); $this-&gt;getObject()-&gt;getPeer()-&gt;save(); } </code></pre> <p>The error message I get is that it expects a Doctrine_Collection.</p> <p>How do I create this collection correctly, or how can I save the many to many relationship from within the top form or action?</p>

Guidance
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.
