conceive confirmable not working in the most recent version

advertisements

I recently upgraded from Devise 1.2 to 1.4.9 and everything seems to work except my confirmable module. Email works as well as the entire process. But the confirmation page is always blank. It works and it confirms the email account, but it does not redirect the user and throws a 406 error. It does the same for false confirmation attempts.

Routes seem to work fine, I have confirmable specified in my user model, and nothing else has changed.

Any ideas? Am I missing some settings or something I need to update for 1.4.9?

UPDATE

It seems to be a problem with the URL being generated. For some unknown reason it is prepending the confirmations URL with the user name? and that is causing it to break. But i'm still not sure how to fix it.

http://localhost:5000/users/confirmation.someusername?confirmation_token=R7apAPhC5c3rszvhsowp

The username in the URL above causes the process not to work.

I checked the diff between the controller in 1.2 (which works) and the new version.

1.2

  # GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])

    if resource.errors.empty?
      set_flash_message :notice, :confirmed
      sign_in_and_redirect(resource_name, resource)
    else
      render_with_scope :new
    end
  end

1.4.9

  # GET /resource/confirmation?confirmation_token=abcdef
  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_navigational_format?
      sign_in(resource_name, resource)
      respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
    else
      respond_with_navigational(resource.errors, :status => :unprocessable_entity){ render_with_scope :new }
    end
  end

  protected

    # The path used after resending confirmation instructions.
    def after_resending_confirmation_instructions_path_for(resource_name)
      new_session_path(resource_name)
    end

    # The path used after confirmation.
    def after_confirmation_path_for(resource_name, resource)
      after_sign_in_path_for(resource)
    end

error

Look and see if you copied the have devise views, they may be out of date.

I had a similar issue getting odd user ids in my url, devise no longer uses user_confirmation_url in favor of confirmation_url (as of 1.0?, but it still worked a bit longer) so you might either delete your custom devise views or update the url helper.
