Rails: Generic form actions, cancel link losing `:back` on validation failure
- by Patrick Connor
I am trying to create a generic set of Submit, Cancel, and Destroy actions for forms. At this point, it appears that everything is working, except that I lose :back functionality then a form reloads due to validation errors. Is there a way to catch the fact that validation has failed, and in that case, keep the request.env['HTTP_REFERER'] or :back value the same without having to edit every controller?
= simple_form_for @announcement do |f|
= f.error_notification
= f.input :message
= f.input :starts_at
= f.input :ends_at
#submit
= f.button :submit
= "or "
= link_to("cancel", url_for(:back))
.right
- if !f.object.new_record?
- resource = (f.object.class.name).downcase
= link_to "destroy", url_for(:action => 'destroy'), :confirm => "Are you sure that you want to delete this #{resource}?", :method => :delete
.clear
.non_input
#post_back_msg
#indicator.inline
= image_tag "indicator.gif"
.inline
= "Please wait..."
.non_input
