Question

周四大家快乐，我有一个关于路线和重定向的快速问题。我正在进行一项铁路任务，要求我在登录后将路由器重定向到他/她的个人资料。我将如何做到这一点？ after_sign_in方法？这是我的路线：

Rails.application.routes.draw do
  get 'users/show'

  get 'users_controller/show'

  devise_for :users
  resources :users

  get 'welcome/index'
  root :to => 'welcome#index'
end

用户控制器：

class UsersController < ApplicationController
  def show
    @user = User.find(params[:id])
  end

  private
   def user_params
     params.require(:user).permit(:name, :email)
   end
end

设计/会话（登录页面）

<h2>Sign in</h2>

<div class="row">
  <div class="col-md-8">
    <%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
      <%= devise_error_messages! %>
      <div class="form-group">
        <%= f.label :email %>
        <%= f.email_field :email, autofocus: true, class: 'form-control', placeholder: "Enter email" %>
      </div>
      <div class="form-group">
        <%= f.label :password %>
        <%= f.password_field :password, class: 'form-control', placeholder: "Enter password" %>
      </div>
      <div class="form-group">
        <% if devise_mapping.rememberable? %>
          <%= f.label :remember_me, class: 'checkbox' do %>
            <%= f.check_box :remember_me %> Remember me
          <% end %>
        <% end %>
        <%= f.submit "Sign in", class: 'btn btn-success' %>
      </div>
      <div class="form-group">
        <%= render "devise/shared/links" %>
      </div>
    <% end %>
  </div>
</div>

感谢您的帮助！也有人可以回答为什么我的佣金路线有两个用户#show？我只知道一个函数（带有user_id的函数）所以我不知道如何创建两个函数。

Rake Routes输出：

Answer 1

在after_sign_in_path_for中定义ApplicationController。阅读：https://github.com/plataformatec/devise/wiki/How-To%3A-Redirect-to-a-specific-page-on-successful-sign-in-and-sign-out

Answer 2

默认情况下，Devise会在登录后将用户重定向到root_path。您只需将config / routes.rb中的root设置更改为所需路径，或添加{{1例如

user_root_path

如Devise wiki中所述。

关于这两条路线，请注意您的get '/welcome' => "welcome#index", as: :user_root包含以下两条陈述：

routes.rb

get 'users/show' resources :users自动添加resources映射到GET /users/:id的路由，这是您想要的。应删除另一条路线以及UsersController#show。有关这方面的更多信息，请参阅Rails Routing Guide。

Answer 3

在应用程序控制器中

  def after_sign_in_path_for(user)
    the link that you want 
  end

在您的示例中

  def after_sign_in_path_for(user)
    user_path(current_user.id)
  end

两个用户#show，以及登录后如何重定向到我的用户个人资料
