Question

我正在通过railstutorial.org工作并在第7章。当我添加新用户时，控制器将用户保存到数据库然后挂起语句redirect_to @user然后大约2分钟后返回url /用户声称用户已存在。看起来它正在做的是成功执行创建控制器，保存用户，挂起redirect_to调用，然后调用带有错误的创建操作。这是我的代码，提前感谢您的任何帮助

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

  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      #flash[:success] = "Welcome to the Sample App!"
      #render 'show'
      redirect_to user_url(@user.id)
    else
      render 'new'
    end
  end

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

和routes.rb

SampleApp::Application.routes.draw do

  match '/signup',  to: 'users#new',              via: 'get'
  resources :users
  root 'static_pages#home'
  #match '/create',  to: 'user#show',              via: 'post'

  match '/help',    to: 'static_pages#help',      via: 'get'
  match '/about',   to: 'static_pages#about',     via: 'get'
  match '/contact', to: 'static_pages#contact',   via: 'get'

编辑：所以我粘贴了下面的开发日志的输出。我想好消息是它确实首先产生了一个合适的重定向（重定向Redirected to https://rails_chp3-c9-jd8001.c9.io/users/26是我期望它做的......所以这很好）。不幸的是，页面永远不会呈现，并在两分钟后用POST数据重新加载/ user url。我还删除了状态：see_other并返回（上面更新的当前代码）

Answer 1

我首先要删除

status: :see_other and return

来自重定向呼叫的

。此外，尝试查看您的日志，看看它是否给您任何想法。

Answer 2

尝试更改您的create方法以重定向到@user而不是user_url（@ user.id） @ user.id，很可能是整数用户号。

def create
    @user = User.new(user_params)
    if @user.save
      #flash[:success] = "Welcome to the Sample App!"
      #render 'show'
      redirect_to @user
    else
      render 'new'
    end
  end
