Hi   I have a model class SDResolution.It has fields code and solution.I have to make the solution not empty .So for that I wrote validates_presence_of :resolution in the model.So from the view when I click save nothing is saved to database.This is what I need.But no error messages are printed and the view goes to next window..How can I print error messages in the current window?

Thanks in advance Sijo

that's a question of your controller logic.

do it something like that:

def update   @sdresolution = SDResolution.find(params[:id]   if @sdresolution.update_attributes(params[:sdresolution]) then     ...render next view---   else     redirect_to edit action (or just render edit view again)   end end

in your view (for edit) just add <%= error_messages_for(:SDResolution) %> this will display error messages if there are any on the @sdresolution object

Hi      I am using ajax submit to remote here..I could succeed this validation on another place without ajax..I am attaching the code for this .Could you please go through it and make a suggestion?

Thanks Sijo

had a very short look at it (sorry, have some work to do)

but it seems in your action you do: @update_sd_ticket_resolution=@sd_ticket_resolution.update_attributes(params[:sd_resolution])

using @sd_ticket_resolution

while your view uses: <%= error_messages_for 'service_desk_resolution' %>

this should be <%= error_messages_for 'sd_ticket_resolution' %>

to render the errors that may be on @sd_ticket_resolution after the update_attributes
