在忘记密码上设计路由错误

Question

当我点击<%= link_to "Forgot your password?", new_password_path(resource_name) %>

它需要我

http://0.0.0.0:3000/users/password/new

与路由错误

ActionController::RoutingError in Devise/passwords#new

Showing app/views/devise/passwords/new.html.erb where line #3 raised:

No route matches {:controller=>"users", :action=>"password", :id=>:user}

编辑：

new.html.erb此行出错

<%= form_for(resource, :as => resource_name, :url => password_path(resource_name), :html => { :method => :post }) do |f| %>

Passwords_controller.rb

class Devise::PasswordsController < ApplicationController
  #prepend_before_filter :require_no_authentication
  include Devise::Controllers::InternalHelpers

  access_control do
      allow all
  end

  # GET /resource/password/new
  def new
    build_resource({})
    render_with_scope :new
  end

  # POST /resource/password
  def create
    self.resource = resource_class.send_reset_password_instructions(params[resource_name])

    if successful_and_sane?(resource)
      set_flash_message(:notice, :send_instructions) if is_navigational_format?
      respond_with({}, :location => after_sending_reset_password_instructions_path_for(resource_name))
    else
      respond_with_navigational(resource){ render_with_scope :new }
    end
  end

  # GET /resource/password/edit?reset_password_token=abcdef
  def edit
    self.resource = resource_class.new
    resource.reset_password_token = params[:reset_password_token]
    render_with_scope :edit
  end

  # PUT /resource/password
  def update
    self.resource = resource_class.reset_password_by_token(params[resource_name])

    if resource.errors.empty?
      set_flash_message(:notice, :updated) if is_navigational_format?
      sign_in(resource_name, resource)
      respond_with resource, :location => redirect_location(resource_name, resource)
    else
      respond_with_navigational(resource){ render_with_scope :edit }
    end
  end

  protected

    # The path used after sending reset password instructions
    def after_sending_reset_password_instructions_path_for(resource_name)
      new_session_path(resource_name)
    end

end

我遇到了类似的问题。 我错过了User模型中的recoverable模型：

class User
  devise :database_authenticatable,
         :registerable,
         :validatable,
         :recoverable
end

一旦我添加:recoverable我在运行rake routes时看到了丢失的密码rake routes ：

         user_password POST   /users/password(.:format)                       devise/passwords#create
   new_user_password GET    /users/password/new(.:format)                   devise/passwords#new
  edit_user_password GET    /users/password/edit(.:format)                  devise/passwords#edit
                     PUT    /users/password(.:format)                       devise/passwords#update

我想你在routes.rb中缺少这一行

devise_for :users

如果这对您没有帮助，那么我建议您遵循这两个railscast：

• http://railscasts.com/episodes/209-introducing-devise
• http://railscasts.com/episodes/210-customizing-devise

你会在那里找到所有必要的信息。
