Rails 应用中的 Factory Bot 失败

Question

所以我有以下模型：区域和位置。它们看起来不错，我可以很好地加载页面。问题出在工厂机器人身上。

class Region < ApplicationRecord
 scope :ordered, -> { order(name: :desc) }
 scope :search, ->(term) { where('name LIKE ?', "%#{term}%") }
 has_many :locations, dependent: :destroy
end

class Location < ApplicationRecord
 scope :ordered, -> { order(name: :desc) }
 scope :search, ->(term) { where('name LIKE ?', "%#{term}%") }
 belongs_to :region
end

对于我的工厂，我有以下内容：

FactoryBot.define do
 factory :region do
  name 'MyString'
 end
end

FactoryBot.define do
 factory :location do
 name 'MyString'
 hours_operation 'MyString'
 abbreviation 'MyString'
 region nil
 end
end

这两个都非常容易呈现，我对它们所做的唯一更改是将双引号换成单引号。但是当我运行 a bin/test 我不断收到以下错误： Admin::LocationsController show should render the show page Failure/Error: location = FactoryBot.create(:location) ActiveRecord::RecordInvalid:Validation失败：区域必须存在

然后是失败的协调示例：rspec ./spec/controllers/admin/locations_controller_spec.rb:16 # Admin::LocationsController show should render the show page

所以我查看了 spec/controllers/admin/locations_controller_spec.rb，这是代码：

require 'rails_helper'

RSpec.describe Admin::LocationsController, type: :controller do
 before(:each) do
   activate_session(admin: true)
 end

describe 'index' do
  it 'should render the index' do
    get :index
    expect(response).to have_http_status :success
   end
 end

 describe 'show' do
  it 'should render the show page' do
   location = FactoryBot.create(:location)
   get :show, params: { id: location.id }
   expect(response).to have_http_status :success
  end

  it 'should return a 404 error' do
    get :show, params: { id: 1 }
    expect(response).to have_http_status :not_found
  end
end
describe 'new' do
  it 'should render the new page' do
    get :new
    expect(response).to have_http_status :success
  end
end

describe 'edit' do
  it 'should render the edit page' do
    location = FactoryBot.create(:location)
    get :edit, params: { id: location.id }
    expect(response).to have_http_status :success
  end
end

describe 'create' do
  it 'should create the record' do
    expect do
      post :create, params: { location: 
  FactoryBot.attributes_for(:location) }
    end.to change(Location, :count).by(1)
  end
end

describe 'update' do
  it 'should update the record' do
    location = FactoryBot.create(:location)
    current_value = location.name
    new_value = current_value + '-Updated'
    expect do
      patch :update, params: { id: location.id, location: { name: new_value } }
      location.reload
    end.to change(location, :name).to(new_value)
  end
end

describe 'destroy' do
  it 'should destroy the record' do
    location = FactoryBot.create(:location)
    expect do
      delete :destroy, params: { id: location.id }
    end.to change(Location, :count).by(-1)
  end
 end
end

它引用的行是：'should render the show page'.

老实说，我不知道是什么导致它失败。我认为这可能是一个关联问题，但是当我尝试做一些类似 associations :location 的事情时，它导致了更多的错误。我只是在关联的规范控制器中遗漏了一些东西吗？

EDIT/UPDATE：修复了在位置中使用关联 :region 的六个错误中的五个。但我得到： Failure/Error: expect do post :create, params: { location: FactoryBot.attributes_for(:location) } end.to change(Location, :count). by(1) 预计 #count 已更改为 1，但已更改为 0。

Answer 1

您可以使用 after_create 在 factory-bot 中创建关联，试试这个

FactoryBot.define do
 factory :location do
  name 'MyString'
  hours_operation 'MyString'
  abbreviation 'MyString'
  after(:create) do |location, evaluator|
   location.region = FactoryBot.create(:region)
  end
 end

结束

这一切所做的就是创建一个 region 对象并将其关联到 location 对象。
