param丢失或值为空： - RSpec

Question

我已经彻底研究过这个问题，但我似乎无法找到答案。我正在编写一个模型规范，一切似乎都很常规，但我一直收到这个错误 - param is missing or the value is empty: subscriber - 我真的不知道还能说什么？我会发布我的代码和错误，以便更清晰。

CONTROLLER：

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

SPEC：

 require "rails_helper"

 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, comment: comment }.to change(Comment, :count).by(1)
  end
 end

ERROR：

在您的强力参数中，您需要订阅者，但您没有根据您的请求发送订阅者。请尝试以下方法：

  require "rails_helper"

 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
