    <p>I'm new to Rails and I'd like to know if I could refactor the following code.</p> <p>Basically I want to vote_down ou vote_up for a question in ajax.</p> <p>Controller :</p> <pre><code>def vote_up @question = get_question params[:id] if current_user != @question.user render :json =&gt; @question.vote(current_user, 'up').to_json end end def vote_down @question = get_question params[:id] if current_user != @question.user render :json =&gt; @question.vote(current_user, 'down').to_json end end </code></pre> <p>Model :</p> <pre><code>def vote(user, vote) if user.voted?(self) 'Question already voted' else I18n.t('question.voted') if user.send("#{vote}_vote", self) end end </code></pre> <p>View :</p> <pre><code>&lt;script&gt; $('#question_vote_up').live('ajax:success', function(evt, data, status, xhr) { $('#question_vote_up').remove() $('#question_vote_down').remove() alert(xhr.responseText) }) $('#question_vote_down').live('ajax:success', function(evt, data, status, xhr) { $('#question_vote_up').remove() $('#question_vote_down').remove() alert(xhr.responseText) }) &lt;/script&gt; &lt;% if current_user != @question.user %&gt; &lt;%= link_to t('question.vote_up'), { :action =&gt; "vote_up" }, :id =&gt; "question_vote_up", :remote =&gt; true %&gt; &lt;%= link_to t('question.vote_down'), { :action =&gt; "vote_down" }, :id =&gt; "question_vote_down", :remote =&gt; true %&gt; &lt;% end %&gt; </code></pre> <p>I can't figure out how don't repeat myself and if there is a cleaner way to </p> <pre><code>if current_user != @question.user </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
