未定义的方法`permit＆＃39; for＆＃34; 1＆＃34;：String - RSPEC

Question

我有点荒谬但我真的不知道这个错误试图告诉我什么？我是rspec的新手，对我来说这是一个新手。为了清楚起见，我会发布我的代码 - 错误：未定义的方法`permit＆＃39; for＆＃34; 1＆＃34;：String |

控制器：

def subscriber_params
  params.require(:subscriber).permit(:first_name, :last_name, :email, :phone_number)
end

SPEC：       要求＆＃34; rails_helper＆＃34;

describe SubscribersController do
  include Devise::TestHelpers

  let(:user) { FactoryGirl.create(:user) }
  let(:subscriber) { FactoryGirl.create(:subscriber) }

  it "creates a new comment" do
    sign_in(user)
    comment = FactoryGirl.attributes_for(:comment)

    expect { post :create, subscriber: subscriber, comment: comment }.to change(Comment, :count).by(1)
  end
end

错误：

Answer 1

更改

let(:subscriber) { FactoryGirl.create(:subscriber) }

到

let(:subscriber) { FactoryGirl.attributes_for(:subscriber) }

因为您要将订阅者的属性添加到请求而不是订阅者的实例。
