Rails 3覆盖Devise会话控制器

Question

我需要在登录过程中重写Devise会话控制器(Rails 3.0.9,Ruby 1.9.2,Devise 1.3.4),我尝试了这个没有任何影响

class SessionsController < Devise::SessionsController

  # GET /resource/sign_in
  def new
    resource = build_resource
    clean_up_passwords(resource)
    respond_with_navigational(resource, stub_options(resource)){ render_with_scope :new }
  end

end

想法？

编辑 如答案所示,我还需要改变路线.另外,我还需要复制视图.这里有更好的解释 http://presentations.royvandewater.com/authentication-with-devise.html#8

我的自定义策略:

devise.rb
config.warden do |manager|
  manager.strategies.add(:custom_strategy) do
    def authenticate!
      ... authenticate against 3rd party API...
      if res.body =~ /success/
        u = User.find_or_initialize_by_email(params[:user][:email])
        if u.new_record?
          u.save
        end
      success!(u)
    end
  end
end

您是否改变了使用新控制器的路线？

/config/routes.rb

  devise_for :users, :controllers => {:sessions => "sessions"}
