我的控制器的 rspec 测试返回 nil（+工厂女孩）

我正在用 rspec 和 Factory Girl 在 Rails 上学习测试，但我无法让它们工作。

我的用户控制器如下所示：

class UsersController < ApplicationController
  def index
    @users = User.all.order(:first_name)
  end
end

和测试：

require 'spec_helper'

describe UsersController do

before(:each) do
    @user1 = FactoryGirl.create(:user, first_name: "B", last_name: "B", uid: "b")
    @user2 = FactoryGirl.create(:user, first_name: "A", last_name: "A", uid: "a")
end

describe "GET index" do     
    it "sets a list of users sorted by first name" do
        get :index
        assigns(:users).should == [@user2, @user1]
    end
end
end

但测试返回以下结果：

UsersController GET index sets a list of users sorted by first name
Failure/Error: assigns(:users).should == [@user2, @user1]
expected: [#<User id: nil, email: nil, first_name: "A", last_name: "A", uid: "a", active: true, admin: false, created_at: nil, updated_at: nil, reset_date: nil>, #<User id: nil, email: nil, first_name: "B", last_name: "B", uid: "b", active: true, admin: false, created_at: nil, updated_at: nil, reset_date: nil>]
got: nil (using ==)
# ./spec/controllers/users_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

你知道我做错了什么吗？

Cheers!

这是“耙子路线”：

        root GET    /                                  meetings#index
    meetings GET    /meetings(.:format)                meetings#index
       login GET    /login(.:format)                   sessions#new

   edit_user GET    /users/:id/edit(.:format)          users#edit
        user GET    /users/:id(.:format)               users#show
             PATCH  /users/:id(.:format)               users#update
             PUT    /users/:id(.:format)               users#update
             DELETE /users/:id(.:format)               users#destroy

正如Jvnill上面所说，使用create。另一种选择是在声明它们后使用@user1.save。

另外，就路由而言，请检查路由文件中的资源。
