Rails 4 Inline Error Messages
helping each other. Join them; it only takes a minute: Sign up How to display Ruby on Rails form validation error messages one at a time up vote 22 down vote favorite 8 I'm trying to understand how http://stackoverflow.com/questions/5646855/how-to-show-error-messages-next-to-field I can achieve this. Can anyone advise me or point me in the right direction? This allows 1 error from each field to display at a time. It is nearly what I want to do but not quite exactly. I want to display 1 whole error message at a time. E.G. first name can't be blank. Once that has been resolved it moves onto the next error. So if the user added numbers to their last http://stackoverflow.com/questions/7878662/how-to-display-ruby-on-rails-form-validation-error-messages-one-at-a-time name it wouldn't be blank any more but it would show another error stating only letters were allowed etc. When that error was fixed it would go to last name error or maybe email if the user field out their last name correctly. <% @user.errors.each do |attr, msg| %> <%= "#{attr} #{msg}" if @user.errors[attr].first == msg %> <% end %> ruby-on-rails ruby rubygems share|improve this question edited Jan 5 at 21:05 Simone Carletti 122k24253297 asked Oct 24 '11 at 16:19 LondonGuy 4,004540100 add a comment| 3 Answers 3 active oldest votes up vote 34 down vote ActiveRecord stores validation errors in an array called errors. If you have a User model then you would access the validation errors in a given instance like so: @user = User.create[params[:user]] # create will automatically call validators if @user.errors.any? # If there are errors, do something # You can iterate through all messages by attribute type and validation message # This will be something like: # attribute = 'name' # message = 'cannot be left blank' @user.errors.each do |attribute, message| # do stuff for each error end # Or if you prefer, you can get the full message in single string, like so: # message = 'Name cannot be left blank' @users.errors.full_messages.each do |message| # do stuff for each error end # To get all errors associated with a
one of the first things that came out and bit me is that the error_message_on helper method, which was http://hibbard.eu/inline-error-messages-with-rails-3/ previously used to display error messages next to the form fields http://apidock.com/rails/ActionView/Helpers/ActiveRecordHelper/error_messages_for that had caused them, has been deprecated. It took me a 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 error message now available as a plugin named dynamic_form. This means that you could just add ‘dynamic_form' to your gem file, run 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 rails error message 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 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}"

The last existing version (v2.3.8) is shown here. error_messages_for(*params) public Returns a string with a DIV containing all of the error messages for the objects located as instance variables by the names given. 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
