如何在RSpec Rails请求规范中传递额外的参数

Question

我还是初学者，所以我想做的可能不是最佳的，随意提出更好的方法：

我正在尝试测试为关联用户创建合约。用户和authenticate_user方法将被存根，但是RSpec说它没有在我传入的params中传递的user_id外键：contract_params。有人可以告诉我传递user_id的方法，以便RSpec识别它吗？ 谢谢！

规格/请求/ contracts_api_spec.rb

RSpec.describe "ContractsApi", type: :request do

  describe "POST #create" do
    let (:contract_params) do
      {
        user: {
          vendor: "Lebara",
          starts_on: "2018-12-12",
          ends_on: "2018-12-16",
          price: "15",
          user_id: "8"
        }
      }
    end
    before(:each) do
      controller.stub(:authenticate_user)
    end

    it 'creates a new contract' do
      expect { post api_v1_user_contracts_path, params: contract_params }.to change(Contract, :count).by(1)
    end
  end
end

应用程序/控制器/ API / V1 / contracts_controller.rb

class Api::V1::ContractsController < ApplicationController
  before_action :authenticate_user

  def create
    contract = @current_user.contracts.build(contract_params)
    if contract.save
      render json: contract
    else
      render json: contract.errors
    end
  end

  private

  def contract_params
    params.require(:contract).permit(:vendor, :starts_on, :ends_on, :price)
  end

阅读No route matches {:action=>"show", :controller=>"schools"} missing required keys: [:id]后，我意识到需要将user_id附加到url路径，因此我通过进行以下更改获得了成功：

describe "POST #create" do
    let (:contract_params) do
      {
        vendor: "Lebara",
        starts_on: "2018-12-12",
        ends_on: "2018-12-16",
        price: "15",
      }
    end
    before(:each) do
      @user = User.create(full_name: "Jason Bourne", email: "jbourne@test.com", password: "123456")
      controller.stub(:authenticate_user)
    end

    it 'creates a new contract' do
      expect { post api_v1_user_contracts_path(@user), params: contract_params }.to change(Contract, :count).by(1)
    end
  end
end
