我设置了Devise身份验证设置并且正常工作，并且我在注册或登录后立即将用户重定向到用户自己的显示页面。用户显示页面和用户编辑页面可以在浏览器中成功访问：
myapp.com/users/1和 myapp.com/users/1/edit
因为我已经设置了用户控制器 - 现在我需要简单地采取通常在myapp.com/users/edit上发布的设置
edit_user_registration GET /users/edit(.:format) devise/registrations#edit
...这实际上是编辑用户帐户的功能，我需要让它出现在users /：id / edit。当我访问用户的users / 1 / edit页面并更新电子邮件或密码并点击“更新”...网址更改为myapp.com/users/update_account时出现以下错误：
Unknown action
The action 'update' could not be found for UsersController
配置/ routes.rb中
devise_for :users
resources :users
resources :users, only: [:edit] do
collection do
patch 'update'
end
end
root 'static_pages#home'
get '/users/:id', :to => 'users#show'
get '/users/:id/edit', :to => 'users#edit'
get '/help', to: 'static_pages#help'
get '/about', to: 'static_pages#about'
rake routes提供：
Prefix Verb URI Pattern Controller#Action
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy

我的用户控制器：
class UsersController < ApplicationController
before_filter :authenticate_user!
def edit
@user = current_user
end
def update
@user = User.find(current_user.id)
if @user.update_with_password(user_params)
# Sign in the user by passing validation in case their password changed
sign_in @user, :bypass => true
redirect_to @user
else
render "edit"
end
end
private
def user_params
params.require(:user).permit(:email, :password, :password_confirmation, :current_password)
end
end

如何解决此错误的任何帮助将不胜感激。
答案 0 :(得分：1)
浏览器正在发送PATCH /users/update_account，看起来就像你想要的那样。但是，匹配的rake routes中的第一行是：
PATCH /users/:id(.:format) users#update
... 不是你想要的东西。
你在config / routes.rb中有两次resources :users;你应该只拥有一次。试试这个：
resources :users do
collection do
patch 'update_account'
end
end
这将生成users的所有标准路线，正如您的顶线目前所做的那样，还有/users/update_account - 我认为之前所有标准路线。
