    copied!<p>I have a model with a method called date_string. The point of this method is to return a formatted date string when being used in a share view. Here is the view code.</p> <pre><code>&lt;div class="field control-group"&gt; &lt;div class="control-label"&gt; &lt;%= f.label :business_hour , :date_string %&gt; &lt;/div&gt; </code></pre> <p>I am expecting the f.label call to function like in this <a href="http://apidock.com/rails/v3.2.13/ActionView/Helpers/FormHelper/label" rel="nofollow">api doc</a>, with :business_hour being the object, and :date_string being the method. However, the only thing that is rendered to the view is the string 'Date string' or 'date_string'. </p> <p>Any help on getting a view class to call a method, not a property, on a model is greatly appreciated.</p> <p>Business_Hour code</p> <pre><code>class BusinessHour &lt; ActiveRecord::Base attr_accessible :business_hourable_id, :business_hourable_type, :close_time, :day, :open_time, :order , :business_date belongs_to :business_hourable , :polymorphic =&gt; true def date_string() if business_date.nil? return '' else return_string = business_date.strftime( '%a %b\ %e , %Y' ) end end </code></pre> <p>end</p> <p>Here is the full partial code(shared/business_hours):</p> <pre><code>&lt;div class="field control-group"&gt; &lt;div class="control-label funkiness"&gt; &lt;%= F.label :business_hour , :date_string %&gt; &lt;/div&gt; &lt;div class="controls"&gt; &lt;%= f.select :open_time, available_hours, :include_blank =&gt; true %&gt; &lt;/div&gt; &lt;div class="control-label"&gt; &lt;%= f.label :open_time, 'Close Time' %&gt; &lt;/div&gt; &lt;div class="controls"&gt; &lt;%= f.select :close_time, available_hours, :include_blank =&gt; true %&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>Here is the pertinent part of the _form &lt;%= form_for (@some_show), html: {class: "form-horizontal pull-left"} do |f| %> ... &lt;%= f.fields_for :business_hours do |operating_time| %> &lt;%= render :partial => 'shared/business_hours', :locals => {:f => operating_time} %> &lt;% end %> </p> <p>And finally, here is the edit action of the controller</p> <pre><code># GET /some_shows/1/edit def edit @some_show = SomeShow.find(params[:id]) end </code></pre>
