Question

spec / controllers / profiles_controller_spec.rb中有一个奇怪的错误：未定义的局部变量或方法'profile'

粘贴在控制器的相关部分：

require 'rails_helper'
require 'factory_girl'

describe ProfilesController, :type => :controller do
  login_user #this is defined elsewhere, not an issue
  describe "PUT update" do
    before(:each) do
      @profile = FactoryGirl.create(:profile)
    end
    context "valid attributes" do
      it "located the requested @profile" do
        put :update, id: @profile, profile: FactoryGirl.attributes_for(:profile)
        assigns(:profile).should eq(@profile)
      end
    end
  end
end

Answer 1

我的猜测是您的规格或工厂没有问题。问题在于您正在测试的控制器。

您看到的例外

1) ProfilesController PUT #update valid attributes located the requested @profile
   Failure/Error: put :update, id: @profile, profile: FactoryGirl.attributes_for(:profile)
   NameError:
     undefined local variable or method `profile' for #<ProfilesController:0x007fae343cfe08>

告诉您ProfilesController有未定义的局部变量或方法profile。

在你的控制器中，你有这一行

if @profile.update(profile)

最有可能导致错误。也许您需要将update(profile)更改为update(profile_params)？如果没有看到整个控制器，这很难说，但这将遵循一个共同的模式。我想你有一个方法profile_params可以返回过滤后的参数。

Answer 2

您是否在test/factories.rb或spec/factories.rb？

中定义了工厂

它看起来像这样：

# This will guess the User class
FactoryGirl.define do
  factory :user do
    first_name "John"
    last_name  "Doe"
    admin false
  end

  # This will use the User class (Admin would have been guessed)
  factory :admin, class: User do
    first_name "Admin"
    last_name  "User"
    admin      true
  end
end
