    <p>I have two models , <code>Place</code> and <code>Address</code>. And the models relationships are,</p> <p>In <code>Place</code>, <code>has_one :address , :dependent =&gt; :destroy</code> In <code>Address</code>, <code>belongs_to :place</code>.</p> <p>In new form in <code>Places Controller</code> I can add the fields to <code>Address</code> without any problem using <code>fields_for :address</code> in form.</p> <p>But when showing , a <code>Place</code> details, I cannot get the <code>Address</code> details of that place. I don't know where I am doing a mistake.</p> <p>In <code>show.html.erb</code> in <code>Places Controller</code>, I have,</p> <pre><code>&lt;% @places.each do |place| %&gt; &lt;p&gt; &lt;b&gt;Max people:&lt;/b&gt; &lt;%=h place.max_people %&gt; &lt;/p&gt; &lt;p&gt; &lt;b&gt;Street:&lt;/b&gt; &lt;%=h place.address.street %&gt; &lt;/p&gt; &lt;p&gt; City: &lt;/b&gt; &lt;%=h place.address.city %&gt; &lt;/p&gt; &lt;p&gt; Pincode: &lt;/b&gt; &lt;%=h place.pincode %&gt; &lt;/p&gt; &lt;% end %&gt; </code></pre> <p>So , in <code>PlacesController</code> ,</p> <pre><code>def show @userid=session[:userid] @places = Place.find(:all , :conditions =&gt; ["user_id = ?", @userid]) respond_to do |format| format.html # show.html.erb format.xml { render :xml =&gt; @place } end end </code></pre> <p>which displays all the <code>Place</code> details properly but not <code>Address</code> details. I have searched through SO for finding my mistake but all I found was problem with forms. In my case, new form working properly, but not show.</p> <p>Error is ,</p> <pre><code> NoMethodError in Places#show Showing app/views/places/show.html.erb where line #9 raised: undefined method `street' for nil:NilClass </code></pre> <p>In console,</p> <pre><code> `Place.last.address.street` gives me correct data. </code></pre> <p>Am I missing something? Thanks.</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.
