    copied!<p>I'm working on a roleplaying game character database app and I need some help.</p> <p>I've got two models, Character and Statistic. Each Character will have one instance of the Statistic model, which is a table with 6 separate statistics. I've used a partial to render the Statistic form on the Character view, so I can create a new Statistic that is associated with that Character from the Character view. However, I can't edit the Statistic and I can generate more than one instance, which are both problems. </p> <p>My questions are:</p> <p>How do I code an edit action in the Statistic controller so that I can edit the instance of Statistic from the Character view? I also want this to over write any Statistic instance that is present, so that I don't end up with multiple sets of Statistics per Character.</p> <p>Thanks!</p> <p>EDIT: Here's some code:</p> <p>From the Statistic controller:</p> <pre><code>def edit @statistic = Statistic.find(params[:id]) end </code></pre> <p>From the Character view:</p> <pre><code>%= render "statistics/form" % </code></pre> <p>And the form this code renders:</p> <pre><code>%= form_for([@character, @character.statistics.build]) do |f| %&lt;br /&gt; div class="field"&lt;br /&gt; %= f.label :strength % &lt;br /&gt; %= f.text_field :strength %&lt;br /&gt; /div&lt;br /&gt; div class="field"&lt;br /&gt; %= f.label :dexterity %br /&lt;br /&gt; /div&lt;br /&gt; div class="field"&lt;br /&gt; %= f.label :constitution %&lt;br /&gt; %= f.text_field :constitution %&lt;br /&gt; /div&lt;br /&gt; div class="field"&lt;br /&gt; %= f.label :intelligence %&lt;br /&gt; %= f.text_field :intelligence %&lt;br /&gt; /div&lt;br /&gt; div class="field"&lt;br /&gt; %= f.label :wisdom %&lt;br /&gt; %= f.text_field :wisdom %&lt;br /&gt; /div&lt;br /&gt; div class="field"&lt;br /&gt; %= f.label :charisma %&lt;br /&gt; %= f.text_field :charisma %&lt;br /&gt; /div&lt;br /&gt; div class="actions"&lt;br /&gt; %= f.submit %&lt;br /&gt; /div&lt;br /&gt; % end %&lt;br /&gt; </code></pre>
