    <p>I've got problems with making update action for one of my data objects. I've got:</p> <pre><code>class UserProfile &lt; ActiveRecord::Base belongs_to :address, :dependent =&gt; :destroy belongs_to :post_address, :class_name =&gt; 'Address', :dependent =&gt; :destroy accepts_nested_attributes_for :address accepts_nested_attributes_for :post_address # validations and stuff end class Address &lt; ActiveRecord::Base # validations and stuff end </code></pre> <p>And the problem is with the form and action:</p> <pre><code>= form_for @up, :url =&gt; '/profile/edit', :method =&gt; :post do |f| = f.error_messages #... = f.fields_for :address, @up.address do |a| #... = f.fields_for :post_address, @up.post_address do |a| #... .field.push = f.submit 'Save', :class=&gt;'ok' </code></pre> <p>Action:</p> <pre><code>def edit_account @user = current_user if request.post? @up = @user.user_profile.update_attributes(params[:user_profile]) if @up.save redirect_to '/profile/data', :notice =&gt; 'Zmiana danych przebiegła pomyślnie.' end else @up = @user.user_profile end end </code></pre> <p>The error I get looks like this:</p> <pre><code>Couldn't find Address with ID=3 for UserProfile with ID=2 </code></pre> <p>And it occurs in the line: </p> <pre><code>@up = @user.user_profile.update_attributes(params[:user_profile]) </code></pre> <p>I think that AR tries to create another <code>Address</code> when the form is submitted but I'm not certain.</p> <p>Why do I get this error? What's wrong with my code?</p>

    3. COah, sorry. I was thinking you were going the equivalent of new/create/edit/update RESTful controller actions.

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.
