My personal preference is to use simple_form and have it put the error next to the input. share|improve this answer answered Jul 15 '13 at 20:41 Jesse Wolgamott 36k36194 add a comment| up vote 20 down vote This is how I am displaying them for my form object called @location: <% if @location.errors.any? %>
- <% @location.errors.full_messages.each do |msg| %>
- <%= msg %> <% end %> <% end %> Note: put the above code after the <%= form_for @location do |f| %> line share|improve this answer answered Nov 2 '13 at 23:42 Danny 2,1392132 add a comment| up vote 6 down vote My preferred way of doing this and keeping the code simple and DRY, is the following: Create a new helper inside of application_helper.rb # Displays object errors def form_errors_for(object=nil) render('shared/form_errors', object: object) unless object.blank? end Create a new shared partial in shared/_form_errors.html.erb <% content_for :form_errors do %>
<%= pluralize(object.errors.count, "error") %> prevented the form from being saved:
- <% object.errors.full_messages.each do |message| %>
- <%= message %> <% end %> <% end %> Edit your application.html.erb file to include the errors where you want them: <%= yield :form_errors %> Finally,
one of the first things that came out and bit me is that the error_message_on helper method, which was previously used to display error messages next to the form http://hibbard.eu/inline-error-messages-with-rails-3/ fields that had caused them, has been deprecated. It took me a https://gist.github.com/8120567 little while to figure out how to reinstate this functionality. Here's how I did it. First off, we should probably note, that although this method has been removed from Rails, it is now available as a plugin named dynamic_form. This means that you could just add ‘dynamic_form' to your gem file, run error messages bundler and everything would be the same as before. However, as Ryan Bates notes in Railscast 211 (Validations in Rails 3), the reason that this and a couple of other methods (such as error_messages_for) have been removed, is that the display of error messages often needs to be customized and doing this through the old methods was a little bit cumbersome. Instead we now have access rails error messages to @resource.errors which is an instance of the class ActiveModel::Errors containing all errors for a particular resource, where each key is the attribute name and the value is an array of strings with all errors. That means that we can now write: <% if @resource.errors[:field_name] %> <%= @resource.errors[:field_name][0] %> <% end %> and have our errors reappear back inline. Note, that it is necessary to write [:field_name][0], as @resource.errors[:field_name] is an array containing all available error messages and it is probably not a good idea to display all of these to your users in one go. Now, this is all a bit verbose, so it is a good idea to move this code into a helper method. def error_message_for(field, options = {:prepend_text => ""}) error_message = @resource.errors[field][0] if error_message raw "#{options[:prepend_text]} #{error_message}" end end Now you can just write: <%= error_message_for(:field_name, :prepend_text => "Whatever ") %> References: Rails 3 - show error messages next to field Rails 3 - inline errors Working with Validation Errors Tags: rails | ruby This post currently has one response Nick says: January 29, 2014 at 9:48 pm Perfect ! Exactly what i was looking for
