    <p>I have created a model that looks like this:</p> <pre><code>class Parent &lt; ActiveRecord::Base attr_accessible :child, :child_id has_one :child, :class_name =&gt; 'Child', :autosave =&gt; true, :inverse_of =&gt; :parent #parent's validations validates_associated :child end </code></pre> <p>And the child model is like:</p> <pre><code>class Child &lt; ActiveRecord::Base attr_accessible :parent, :parent_id belongs_to :parent, :inverse_of =&gt; :child validates_presence_of :parent #Other custom validations... end </code></pre> <p>When I am at the new child's page, if the user does not choose a previously created parent for the child, I want to force him to create one at the same time he creates the child. It's working fine if the user fills in all the data correctly for the child and the parent, but if the parent has any validation issue on a given field, the only message I get is: "Parent cannot be blank"</p> <p>I wanted to show to the user the same message it would show if he was creating the Parent alone. That should be something like: "Field X of Parent is too short".</p> <p>Is it possible, using validates_associated or with some similar helper?</p> <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.
