    <p>I'm using <a href="http://github.com/josevalim/inherited_resources" rel="nofollow noreferrer">Inherited Resources</a> for my Rails 2.3 web service app. It's a great library which is part of Rails 3. </p> <p>I'm trying to figure out the best practice for outputting the result. </p> <pre><code>class Api::ItemsController &lt; InheritedResources::Base respond_to :xml, :json def create @error = nil @error = not_authorized if !@user @error = not_enough_data("item") if params[:item].nil? @item = Item.new(params[:item]) @item.user_id = @user.id if !@item.save @error = validation_error(@item.errors) end if !@error.nil? respond_with(@error) else respond_with(@swarm) end end end </code></pre> <p>It works well when the request is successful. However, when there's any error, I get a "Template is missing" error. @error is basically a hash of message and status, e.g. <code>{:message =&gt; "Not authorized", :status =&gt; 401}</code>. It seems <code>respond_with</code> only calls <code>to_xml</code> or <code>to_json</code> with the particular model the controller is associated with. </p> <p>What is an elegant way to handle this? I want to avoid creating a template file for each action and each format (create.xml.erb and create.json.erb in this case)</p> <p>Basically I want: </p> <pre><code>/create.json [POST] =&gt; {"name": "my name", "id":1} # when successful /create.json [POST] =&gt; {"message" =&gt; "Not authorized", "status" =&gt; 401} # when not authorized </code></pre> <p>Thanks in advance. </p>

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.
