Question

我想在任何地方显示自定义Devise'忘记密码'表单，我认为它类似于https://github.com/plataformatec/devise/wiki/How-To:-Display-a-custom-sign_in-form-anywhere-in-your-app

所以在config/routes.rb我添加了：

get "/forgot_password" => "desktop#new"

在app/views/desktop/new.html.haml：

      =form_for(resource, :as => resource_name, :url => password_path(resource_name), :html => { :method => :post }) do |f|
        .error-messages
          =devise_error_messages!
        =f.email_field :email, :autofocus => true, :required => true, :class => 'field'
        %br
        %br
        %button.signin-button Send Instructions

在app/controllers/desktop_controller.rb：

class DesktopController < ApplicationController
  def resource_name
    :user
  end

  def resource
    @resource ||= User.new
  end

  def devise_mapping
    @devise_mapping ||= Devise.mappings[:user]
  end

  def new
  end
end

当我导航到/ forgot_password时，出现undefined local variable or method 'resource'错误。我做错了什么？

Answer 1

原来我需要

helper_method :resource, :resource_name, :devise_mapping

在desktop_controller.rb中的方法之后

Answer 2

最好在应用程序助手中定义这些方法

module ApplicationHelper

def resource_name
   :user
  end

  def resource
   @resource ||= User.new
  end

 def devise_mapping
 @devise_mapping ||= Devise.mappings[:user]
 end
 end
