I had two fields in my form i.e start and end time fields, i am validating times but i am not reflecting the error message at the field, what should i have to do to diplay the error as "start time should be before end time". please help me

validate :valid_times

def valid_times     if start_time >= end_time       self.errors.add :start_time, 'has to be before end time'     end   end

Probably your view is not checking for errors on the object. You need code in it something like:

  <% if @widget.errors.any? %>     <div id="error_explanation">       <h2><%= pluralize(@widget.errors.count, "error") %> prohibited this widget from being saved:</h2>       <ul>       <% @widget.errors.full_messages.each do |msg| %>         <li class="error"><%= msg %></li>       <% end %>       </ul>     </div>   <% end %>

Check your view (or layout) for such code, and if not there, stick this in, substituting your model name for widget.

Oh! Okay. That's a bit more tedious code. What you can do then is have the errors attach to the specific fields, and check for them when displaying each field. I think there are some standard ways to do this, but I don't recall offhand where to find examples and instructions. Google is your friend. IIRC, the default stuff will at least put a red box around the specific fields, using CSS....
