Rails3 Devise undefined method `confirmation_url&#

Question

I've seemingly set up Devise for my User authentication, with the :confirmable option set.

Everything seems to run fine when I run it in the browser, I sign up, go to the confirmation url shown in the server log in my rails s console.

However, when I try to add the following to my db/seed.rb

User.create!(:username => 'haar', :email => '[e-mail]', :password => 'password', :password_confirmation => 'password')

And run rake db:setup --trace

I get the following error:

rake aborted!

Any idea what's causing this and how to resolve it?

I have the following line included in my test environment, for the record:

config.action_mailer.default_url_options = { :host => "localhost:3000" }

Running on Ruby 1.8.7, Rails 3.0.8, with devise 1.4.5.

Answer 1

I also had the same issue just doing restart my server do the job for me and this error removed.

just do CTRL + c and then start your server using rails s

Answer 2

It simply turned out that when I ran rails generate devise:views, it generated incorrect paths when compared to the routes devise_for :user generated. It also generated some other issues, such as the user_confirmation_url pointing to @resource, as the first parameter; when it shouldn't have.

(I didn't want the question to be left unanswered, I'm unsure as to the typical etiquette. If I'm wrong in doing this, please let me know).

Answer 3

As an additional, if you're using STI with Devise models, as I am, you can check via the type attribute. So, my code looks like this:

<p><%= link_to 'Confirm my account', manager_confirmation_url(:confirmation_token => @resource.confirmation_token) if @resource.type == 'Manager' %></p>
<p><%= link_to 'Confirm my account', subscriber_confirmation_url(:confirmation_token => @resource.confirmation_token) if @resource.type == 'Subscriber' %></p>
