Error prohibited this user from being saved:

Question

I've been having an issue that I can't seem to fix

3 errors prohibited this user from being saved:

Email can't be blank

Password confirmation doesn't match Password

Password is too short (minimum is 8 characters)

I can't figure out how to get rid of the 3 error prohibited this user from being saved: All I want to display is the errors in bullets. Any ideas on how to go along with this? I'm using Devise, by the way.

Please don't post screenshots of text. Type it out, so we can all read it. — user229044, May 25 '14 at 03:33

We override the devise helper to give us ultimate control over the errors we wish to show. Here is a helpful resource which shows you how to achieve this

--

Helper

As per the answer by Buck Doyle & the attached resource, you may wish to do this:

#app/helpers/devise_helper.rb
module DeviseHelper
  def devise_error_messages!
     resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join
  end
end

This will allow you to change your devise views to include the devise_error_messages! method:

#app/views/devise/registrations/new.html.erb
<%= devise_error_messages! %>

@user302975: I can’t be sure, but I don’t think putting it in `ApplicationHelper` will truly override the Devise helper. That’s why I suggested putting it in an initialiser, and using the name `DeviseHelper`, which will definitely override the existing method. – Buck Doyle May 25 '14 at 15:33
So rename it to `DeviseHelper`? @BuckDoyle – May 25 '14 at 15:33
I don't have a `DeviseHelper` only a `application_helper` and a `home_helper` @BuckDoyle – May 25 '14 at 15:35

Add a *new* file here: `config/initializers/devise_helper_override.rb` and put the `module DeviseHelper` code that I put in my answer. – Buck Doyle May 25 '14 at 15:36

Instead of `|msg| content_tag(:li, msg)`? Sorry for very basic question – May 25 '14 at 15:57

Sorry, this would in your view - instead of just calling `<%= devise_error_messages!`, you could call `<%= raw(devise_error_messages!) %>` – Richard Peck May 25 '14 at 16:12

@RichPeck `<%= raw(devise_error_messages!) %>` this doesn't seem to be working for me – bnussey Oct 15 '14 at 14:35

Try changing to `resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join.html_safe` – Cam Price-Austin Jan 14 '15 at 23:41

The Devise error messages come from a call to devise_error_messages!, which lives in a helper in devise/app/helpers/devise_helper.rb. I found this out by running bundle open devise and looking at the views. The forms views call that helper method.

You could put this code in an initialiser to override it:

module DeviseHelper
  def devise_error_messages!
    return "" if resource.errors.empty?

    messages = resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join

    html = <<-HTML
    <div id="error_explanation">
      <ul>#{messages}</ul>
    </div>
    HTML

    html.html_safe
  end
end

If you compare to the original, you’ll see I just removed the code that constructs the general error message and the h2 that contains it.

Another option would be to duplicate the views outside of the gem, then you can customise them with more granularity. You would run this and then edit the generated views:

rails generate devise:views

My original only has `module ApplicationHelper` and `end`. Is that normal? – May 25 '14 at 15:08
Yes. The `DeviseHelper` lives inside the Devise gem. You won’t see it inside your application structure. You can use the `bundle open devise` command if you want to see the files included in the gem; you’ll find it inside `app/helpers` there. But I don’t recommend editing it, just override it elsewhere. – Buck Doyle May 25 '14 at 15:10
I left a comment on the other answer; how did you perform the override? I think you must put it in the `DeviseHelper` module, otherwise it won’t really override the original. – Buck Doyle May 25 '14 at 15:34
No luck. I've been able to get it working a bit with Rich Pecks post. But I get `

Honestly the cheapest way to do this (although not technically removing the header) is just to add the following in your CSS:

#error_explanation h2 {
  display: none;
}
