    <p>Have you add <code>has_many :awards</code> to the <code>User</code> model? Have you added <code>belongs_to :user</code> to the <code>Award</code> model? Have you added the column <code>user_id</code> to the <code>Award</code> model (using a migration)? You'll need to do these three things to be able to use the <code>user.awards</code> method you're using. Read the <a href="http://www.google.com.au/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;ved=0CFUQFjAA&amp;url=http://guides.rubyonrails.org/association_basics.html&amp;ei=RWjmT9mME429iAertYRZ&amp;usg=AFQjCNEiaqyRhMemV_2s_ZqwjTaYdA42bQ&amp;sig2=1XnJTum0xuhqfgrEgwu2_A" rel="nofollow">Rails Guide on Associations</a> for more detail.</p> <p>Also, <code>append</code> isn't a Ruby method - the closest method would be <code>&lt;&lt;</code>. You would use it like this: </p> <pre><code>a = Award.new(:name =&gt; "Nobody Award", :description =&gt; "From Jonathan", :category =&gt; "Community", :value =&gt; 1337, :level =&gt; 0, :handle =&gt; "nobody_award") user.awards &lt;&lt; a </code></pre> <p>But you could neaten this into one line of code using the <code>create</code> method:</p> <pre><code>a = user.awards.create(:name =&gt; "Nobody Award", :description =&gt; "From Jonathan", :category =&gt; "Community", :value =&gt; 1337, :level =&gt; 0, :handle =&gt; "nobody_award") </code></pre> <p>EDIT: To create the <code>user_id</code> column in the <code>Award</code> model, run the following code from terminal (while in your app's directory):</p> <pre><code>rails generate migration AddUserIdToAward user_id:integer rake db:migrate </code></pre>

    2. COIs user.awards.append(a) a valid statement? I've never seen it (append) before and tried finding it in the docs and couldn't.

    3. COCan't find `append` anywhere - shouldn't have assumed it was valid! Looks like `<<` is the closest to `append` in Ruby. Will edit the answer.

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.

SQuiL has stopped working due to an internal error.

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