    <h3>The situation:</h3> <p>I have something like the following:</p> <pre><code>class Game &lt; ActiveRecord::Base has_many :turns def calculate_score #return score of all turns played so far end end class Turn &lt; ActiveRecord::Base belongs_to :game end </code></pre> <p>... with corresponding controllers. (this isn't exactly what I have, but my question is very general. The question title shows another similar situation)</p> <p>When I am in <strong>/game/:id</strong> (the show action), I display all turns, and have AJAX edit-in-place to update any turns. Updating a turn calls the <strong>update</strong> method of <em>TurnsController</em>.</p> <h3>The question:</h3> <p>How can I, from <em>TurnsController</em>, call an action in the <em>GameController</em> after a turn is updated?</p> <p>I need an action called "turn_updated" in <em>GameController</em> to check all turns and perform manipulations on the collection game.turns .</p> <p>Thanks!</p> <p>PS: Clearly I am new to Rails, so I can't be more specific because I am not exactly sure of how to phrase my question, or of what is possible.</p> <hr /> <h3>Update:</h3> <p>Thanks for the answers so far.</p> <p>I have been using a redirect_to, but my problem with that is that <strong>update</strong> is an AJAX call. It needs to <strong>render :text => @turn.value</strong> in some conditions, and <strong>redirect_to</strong> in others. Since it's an AJAX call, redirect_to replaces the div that showed the turn value with the entire contents of the new address.</p> <p>I am trying things along these lines now:</p> <pre><code>#turn update action def update url = url_for(:controller =&gt; 'games', :action =&gt; 'turn_updated', :id =&gt; @turn.game_id) render :partial =&gt; 'shared/redirect.js.erb', :locals =&gt; {:url =&gt; url} end </code></pre> <p>and the partial is:</p> <pre><code>&lt;script type="text/javascript"&gt;window.location.replace(&lt;%= url %&gt;);&lt;/script&gt; </code></pre> <p>I am getting closer with this, but it seems somewhat flimsy... For instance, if I replace the partial's JS with <em>alert("Works!");</em> it executes the alert, but the redirect doesn't always happen.</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.
