Rails3 Devise undefined method `confirmation_url&#

问题:

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.

回答1:

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).

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

回答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>
