If more than one object is specified, the

errors for the objects are displayed in the order that the object names are provided. This DIV can be tailored by the following options: :header_tag - Used for the header of the error div (default: "h2"). :id - The id of the error div (default: "errorExplanation"). :class - The class of the error div (default: "errorExplanation"). :object - The object (or array of objects) for which to display errors, if you need to escape the instance

variable convention. :object_name - The object name to use in the header, or any text that you prefer. If :object_name is not set, the name of the first object will be used. :header_message - The message in the header of the error div. Pass nil or an empty string to avoid the header message altogether. (Default: "X errors prohibited this object from being saved"). :message - The explanation message after the header message and before the error list. Pass nil or an empty string to avoid the explanation message altogether. (Default: "There were problems with the following fields:"). To specify the display for one object, you simply provide its name as a parameter. For example, for the @user model: error_messages_for 'user' To specify more than one object, you simply list them; optionally, you can add an extra :object_name parameter, which will be the name used in the header message: error_messages_for 'user_common', 'user', :object_name => 'user' If the objects cannot be located as instance variables, you can add an extra :object parameter which gives the actual object (or array of objects to use): error_messages_for 'user', :object => @question.user NOTE: This is a pre-packaged presentation of the errors with embedded strings and a certain HTML structure. If what you need is significantly different from the default presentation, it makes plenty of sense to access the object.errors instance yourself and

In Rails 3 however, error_messages and error_messages_for have been deprecated and have been moved out to a plugin. share|improve this answer edited Dec 29 '12 at 6:12 mahemoff 15.8k1372123 answered Jun 11 '10 at 19:11 morgan freeman 1,90221628 Thanks for the info but how did you know that both have the same params? That's the part that irks me, I don't see any clear reference to that effect. –Bob Jun 11 '10 at 20:38 You're right. I couldn't find any doc for that. Having a look at the code though, make it clear for me: bit.ly/dyXaYs . Seems that all error_messages is doing is call error_messages_for with the options received as params. Hope this helps. –morgan freeman Jun 12 '10 at 4:17 Thanks Cristian. –Bo

There are several ways to achieve it in Rails3 and in Rails2.3.x which are mentioned specifically and that can be handled either in models or controllers or helpers. Solution# 1: If it is needed to be rails 3 error handled in model and message need to be have customized instead of attribute name. Like if the attribute name is “name”but you want to display messages “Employee name cannot be blank” then we have to install “custom-err-msg” plug-in. This plugin gives you the option to not have your custom validation error message prefixed with the attribute name. Ordinarily, if you have, say: validates_acceptance_of : terms, :message => 'Please accept the terms of service' You’ll get the following error message: Terms Please accept the terms of service This plugin allows you to omit the attribute name for specific messages. All you have to do is begin the message with a ‘^’ character. Example: validates_acceptance_of :accepted_terms, :message => '^Please accept the terms of service' step# 1 To install the ”custom-err-msg” plug-in you have to use the command. “ruby script/plugin install https://github.com/gumayunov/custom-err-msg.git” If you are facing problem by installing the plugin then clone it and just copy the folder (”gumayunov-custom-err-msg-640db42”) inside “Vendor/plugin/” folder step# 2 In view file just display it as mentioned below: Similarly it can use in other places like, validates_pre
about lean, pretty code; creating a clean and intuitive user experience always plays a key role in making your application a success. Luckily Rails has a lot of “out of the box” features already bundled from the word go which can help you to quickly achieve this goal. One of the most common features is flash messages; these allow the application to provide feedback to a user after triggering an action. When I started building flash messages into Trado, I was quickly limited by the ability to only display one flash message at any given time. I wanted to display error messages as well as provide hints, so I decided to write my own solution. In order to properly scope out my new solution, I needed to ensure I had a list of user stories which included current and new features. Here was the list I created: I need to be able to… define the type of flash message, i.e. notice, success or error define a bespoke message for each flash add more the one flash message per page, without being limited order the flash messages retain clean code for the layout/controllers I decided to retain a lot of the logic within the app/helpers/application_helper.rb file to keep both the layout and controller files clean and easy to maintain. Although, this solution provided a spanner in the works: controllers do not have any association with helper files. I didn’t want to include the ApplicationHelper in every controller which needed flashes, as that would go against the DRY principle, so I leveraged the inheritance between all controllers and the ApplicationController and included the ApplicationHelper only once. Here is my code so far: app/controllers/application_controller.rb Ruby class ApplicationController < ActionController::Base include ApplicationHelper end 123456789 class ApplicationController < ActionController::Base include ApplicationHelperend app/helpers/application_helper.rb Ruby def flash_message type, text flash[type] ||= [] flash[type] << text end def render_flash flash_array = [] flash.each do |type, messages| messages.each do |m| flash_array << render(partial: 'shared/flash', locals: { :type => type, :message => m }) unless m.blank? end end flash_array.join('').html_safe end 12345678910111213141516171819202122 def flash_message type, text flash[type] ||= [] flash[type] << textenddef render_flash flash_array = [] flash.each do |type, messages|messages.each do |m| flash_array << render(partial: 'shared/flash', locals: { :type => type, :message => m }) unless m.blank?end end flash_array.join('').html_safeend This is quite a lot of code to take in at once, so I’ll break it up and wal
