    <p>When I render XML with an :include clause for a polymorphic association I have, it doesn't work. I end up with the XML returning the object pointers instead of the actual objects, like:</p> <pre><code>&lt;posts&gt; #&lt;Comment:0x102ed1540&gt;#&lt;Comment:0x102ecaa38&gt;#&lt;Comment:0x102ec7fe0&gt;#&lt;Comment:0x102ec3cd8&gt; &lt;/posts&gt; </code></pre> <p>Yet as_json works! When I render JSON with :include clause, the associations are rendered correctly and I get something like:</p> <pre><code>posts":[ {"type":"Comment","created_at":"2010-04-20T23:02:30-07:00","id":7,"content":"fourth comment"}, {"type":"Comment","created_at":"2010-04-20T23:02:26-07:00","id":6,"content":"third comment"}] </code></pre> <p>My current workaround is using XML builder, but I'm not too comfortable with that in the long run. Does anyone happen to know about this issue? I'm kind of in a catch-22 because while XML doesn't render the associations, as_json doesn't render in a kosher json format (returns an array rather than a list of hashes as proper json should) and the deserializer I'm using on the client side would require modification to parse the json correctly. </p> <p><strong>edit</strong> I'm using 2.3.5 - also I am using the has_many_polymorphs gem for polymorphic has many :through, that may be causing an issue...</p> <p>The model is that I have hangouts, and each hangout has many posts which are polymorphic to comments, photos, etc.</p> <p>Controller code for XML: format.xml { render :xml => @hangouts.to_xml(:include => :users , :methods => :posts) }</p> <p>Code for json is similar (in model): def as_json(options) super(:include => :users, :methods => :posts)</p>

    3. COjpartogi, bensie: I'm using 2.3.5 - also I am using the has_many_polymorphs gem for polymorphic has many :through, that may be causing an issue... The model is that I have hangouts, and each hangout has many posts which are polymorphic to comments, photos, etc. Controller code for XML: format.xml { render :xml => @hangouts.to_xml(:include => :users , :methods => :posts) } Code for json is similar (in model): def as_json(options) super(:include => :users, :methods => :posts)

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.
