没有路由匹配{:action =>"show",:controller =>"user",:id => nil}

Question

各位大家好,我有这个问题(帖子标题).

Failure/Error: get :create, :user => { :email => 'foo@example.com', :name => 'userexample' }
ActionController::RoutingError:No route matches {:action=>"show", :controller=>"user", :id=>nil}

这是我的UserController.

class UserController < ApplicationController

  def new
  end

  def create
    @user = User.new(params[:user])
    @user.save
    redirect_to :action => :show, :id => @user.id
  end

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

这是我的routes.rb

::Application.routes.draw do

  devise_for :users
  root :to => "user#index"
  resources :user
  #match "newuser" => "user#new"
  get "user/new"
  post "user/create"
  get "user/:id" => "user#show"

这是我的rspec测试

require 'spec/spec_helper'

describe UserController do
  it "create new user" do
    get :create, :user => { :email => 'foo@example.com', :name => 'userexample' }
      flash[:notice] = 'new user was successfully created.'
    end
  end
end

if @user.save
   redirect_to :action => :show, :id => @user.id
else
