    <p>I have a model with a location attribute, it's a array of two elements; latitude and longitude. I define the accessors for the location like this</p> <pre><code>class Address include Mongoid::Document include Mongoid::Timestamps include Mongoid::Spacial::Document field :location, :type =&gt; Array, spacial: {lat: :latitude, lng: :longitude, return_array: true } #accessors for location def latitude location[0] end def latitude=( lat ) location[0] = latitude end def longitude location[1] end def longitude=( lng ) location[1] = lng end attr_accessible :location, :latitude, :longitude end </code></pre> <p>here is the controller code</p> <pre><code>def create @address = Address.new(params[:address]) if @address.save redirect_to :action =&gt; 'index' else render :action =&gt; 'new' end end def update @address = Address.find(params[:id]) if @address.update_attributes(params[:address]) redirect_to :action =&gt; 'index' else render :action =&gt; 'edit' end end </code></pre> <p>and at the view level</p> <pre><code>&lt;%= f.hidden_field :latitude%&gt; &lt;%= f.hidden_field :longitude%&gt; </code></pre> <p>these hidden field are manipulated via js, and that is ok. I saw it view developers tools</p> <p>Here are the parameters the controller receives</p> <pre><code>"address"=&gt;{"latitude"=&gt;"-38.0112418", "longitude"=&gt;"-57.53713060000001", "city_id"=&gt;"504caba825ef893715000001", "street"=&gt;"alte. brown", "number"=&gt;"1234", "phone"=&gt;"223 4568965"}, "commit"=&gt;"Guardar", "id"=&gt;"504cacc825ef893715000006"} </code></pre> <p>Note that the latitude and longitude parameters changed and thats ok, but this change it's not saved to the mongodb</p> <p>So, The values for latitude and longitude are not saved. Is there any instruction my code is missing?</p> <p>Thanks in advance.</p> <p>--- edit ---</p> <p>here are the working accessors</p> <pre><code> def latitude location[0] end def latitude=( lat ) self.location = [lat,self.location[1]] end def longitude location[1] end def longitude=( lng ) self.location = [self.location[0], lng] end </code></pre>

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.
