    <p>In another question that i asked recently i got a really good answer and the code worked... But i do not know exactly why it works... Now i have a similar problem, but don't know how to solve it...?</p> <p>What i have:</p> <p>Models</p> <pre><code>users questions (with answer_id) answers votes (with answer_id and user_id) </code></pre> <p>model for users:</p> <pre><code>has_many :questions has_many :votes def can_vote_on? (question) !question.answers.joins(:votes).where('votes.user_id = ?', id).exists? end def voted_answer? (question) (what to do here...?) end </code></pre> <p>model for questions:</p> <pre><code>belongs_to :user has_many :answers, :dependent =&gt; :destroy accepts_nested_attributes_for :answers, :reject_if =&gt; lambda { |a| a[:text].blank? }, :allow_destroy =&gt; true </code></pre> <p>model for answers:</p> <pre><code>belongs_to :question has_many :users, :through =&gt; :votes, :dependent =&gt; :destroy has_many :votes </code></pre> <p>model for votes:</p> <pre><code>belongs_to :answer belongs_to :user </code></pre> <p>In my question view i want to make a text bold when the current_used has voted on that specific answer. So how do i finish this:</p> <pre><code>&lt;% for answer in @question.answers %&gt; &lt;% if current_user.voted_answer? (@question) %&gt; &lt;td&gt; &lt;strong&gt;&lt;%= answer.text %&gt;&lt;/strong&gt; &lt;/td&gt; &lt;% else %&gt; &lt;td&gt; &lt;%= answer.text %&gt; &lt;/td&gt; &lt;% end %&gt; &lt;% end %&gt; </code></pre> <p>Thijs</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.
