我正在尝试修改Devise会话控制器以显示用户的个人资料。以下是修改后的会话控制器：
class User::SessionsController < Devise::SessionsController
# before_filter :configure_sign_in_params, only: [:create]
respond_to :json
# GET /resource/sign_in
# def new
# super
# end
# POST /resource/sign_in
# def create
# super
# end
# DELETE /resource/sign_out
# def destroy
# super
# end
# protected
# You can put the params you want to permit in the empty array.
# def configure_sign_in_params
# devise_parameter_sanitizer.for(:sign_in) << :attribute
# end
def show
respond_with User.find(params[:id])
end
end
以下是我在尝试使用json请求点击show方法时的响应：
Started GET "/users/1.json" for ::1 at 2015-10-25 22:47:34 -0400

但我的路线显示路线存在：
Prefix Verb URI Pattern Controller#Action
root GET / application#angular
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
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
PATCH /users/password(.:format) devise/passwords#update
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) devise/registrations#cancel
user_registration POST /users(.:format) devise/registrations#create
new_user_registration GET /users/sign_up(.:format) devise/registrations#new
edit_user_registration GET /users/edit(.:format) devise/registrations#edit
PATCH /users(.:format) devise/registrations#update
PUT /users(.:format) devise/registrations#update
DELETE /users(.:format) devise/registrations#destroy
GET /users/:id(.:format) devise/sessions#show
这是我的routes.rb文件：
Rails.application.routes.draw do
root to: 'application#angular'
devise_for :users, :controllers => {:session => "sessions"}
devise_scope :user do
get '/users/:id' => 'devise/sessions#show'
end
end
任何想法可能出错？
答案 0 :(得分：0)
您实际上可以为用户创建单独的资源。
尝试此命令：
rails generate controller users
然后在用户控制器上添加show方法。
您的路线应如下：
devise_for :users
resources :users
答案 1 :(得分：0)
试
root to: 'application#angular'
devise_for :users, :controllers => {:sessions => "users/sessions"}
"users/sessions"会devise使用您的User::SessionsController代替其默认SessionsController
<强> EDIT1
文件系统结构应该是这样的
app/controllers/users/sessions_controller.rb
class Users::SessionsController < Devise::SessionsController
#use custom layout for devise
layout "login"
end
users目录将所有设计资源控制器分开。 （例如，如果您有多个设计资源，例如users，admin）。如果您需要定义admin资源，则会有admin目录。
