Clearance中UsersController的重写方法

Question

我想更改

  def url_after_create
    '/'
  end

的UsersController。如果我这样做：

class UsersController < Clearance::UsersController
  protected
  def url_after_create
    '/dashboard'
  end

end

当我试图注册一个新用户（在不重写时可以完美工作）时，我会得到以下信息：找不到UsersController的操作"index"——操作（post）是到"/users"，似乎由于没有定义索引操作，它失败了。我该怎么办？

编辑：添加清除代码：：UsersController

class Clearance::UsersController < ApplicationController
  unloadable
  skip_before_filter :authorize,   :only => [:new, :create]
  before_filter :redirect_to_root, :only => [:new, :create], :if => :signed_in?
  def new
    @user = ::User.new(params[:user])
    render :template => 'users/new'
  end
  def create
    @user = ::User.new(params[:user])
    if @user.save
      sign_in(@user)
      redirect_back_or(url_after_create)
    else
      flash_failure_after_create
      render :template => 'users/new'
    end
  end
  private
  def flash_failure_after_create
    flash.now[:notice] = translate(:bad_email_or_password,
      :scope   => [:clearance, :controllers, :passwords],
      :default => "Must be a valid email address. Password can't be blank.")
      end
  def url_after_create
    '/'
  end
end

位于路由中的这条线路match ':controller(/:action(/:id(.:format)))'引起了故障。评论解决了这个问题。
