Rspec has_one 更新时关系错误

Question

我有用户（这是我使用的 Devise）和个人资料模型，其中用户 has_one 个人资料作为他们的关系。运行 rspec 测试时出现错误。以下是我在用户更新 his/her 配置文件时要处理的规范。

spec/controller/profiles_controller_spec.rb

RSpec.describe ProfilesController, type: :controller do
  let(:profile) { FactoryGirl.create(:profile) }
  let (:valid_attributes) { FactoryGirl.attributes_for(:profile) }
  let (:invalid_attributes) { FactoryGirl.attributes_for(:profile).merge({fname: nil}) }
  let(:user) { FactoryGirl.create(:user) }
  let(:valid_session) { sign_in(user) }

  describe "PUT #update" do
    before { valid_session }

    context "with valid attributes" do
      it "saves valid profile" do
        expect do
          put :update, { id: profile.id, profile: { fname: "Cena" } }
        end.to change{ profile.reload.fname }.to("Cena")
      end
    end

spec/factories/profiles.rb

FactoryGirl.define do
  factory :profile do
    user 
    fname "John"
    lname "Doe"
    avatar "my_avatar"
  end
end

app/controller/profiles_controller.rb

class ProfilesController < ApplicationController

private

  def user_params
    params.require(:user).permit(:id, :login, :email,
      profile_attributes: [
        :id, :user_id, :fname, :lname, :avatar, :avatar_cache
      ])
  end

end

这是运行 rspec spec/controllers/accounts_controller_spec.rb

时的错误

Failures:

  1) AccountsController PUT #update with valid attributes saves valid profile
     Failure/Error: put :update, {id: profile.id, user_id: user.id, profile: { fname: "Cena" }}
     ActionController::ParameterMissing:
       param is missing or the value is empty: user

Answer 1

您 post 编辑的 profiles_controller.rb 代码缺少更新操作（并且 class 名称是 AccountController），但我猜您正在做类似 user.update(user_params).

如果是这种情况，如错误所述，从控制器规范传递的参数没有 :user 键，这就是导致错误的原因。

根据#user_params 方法和错误假设，控制器规范中传递给 post 的参数需要如下所示：

{ 
  user: {
    id: xxx, ...,
    profile_attributes: {
      id: xxx, 
      fname: xxx, ...
    }
   }
}

Answer 2

  let(:user) { FactoryGirl.create(:user) }
  let(:profile) { FactoryGirl.create(:profile, user_id: user.id ) }

  describe "PUT #update" do
    before { valid_session }

    context "with valid attributes" do
      it "saves valid profile" do
        expect do
          put :update, id: user.id, user: { profile_attributes: { user_id: user.id, fname: "Cena" } }
        end.to change{ profile.reload.fname }.to("Cena")
      end
    end
  end
