Question

所以我有以下模型：区域和位置。它们看起来很好，我可以加载页面就好了。这个问题来自工厂机器人。

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

这两个都很容易渲染，我对他们做的唯一改变就是用单引号换掉双引号。但是当我运行bin / test时，我不断收到以下错误：Admin :: LocationsController show应该呈现显示页面失败/错误：location = FactoryBot.create（：location）ActiveRecord :: RecordInvalid：验证失败：区域必须存在< / p>

然后是失败的协调示例：rspec ./spec/controllers/admin/locations_controller_spec.rb:16#Admin :: LocationsController show应该呈现显示页面

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

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：'它应该呈现显示页'。

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去尝试做类似关联的事情时：它会导致更多错误填充。我只是在规范控制器中缺少一些关联的东西吗？

编辑/更新：使用关联修复了六个错误中的五个：位置区域。但我得到：失败/错误：期望发帖：create，params：{location：FactoryBot.attributes_for（：location）} end.to change（Location，：count）.by（1）期望#count已更改由1改变，但由0改变。

您可以使用factory-bot在after_create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

端

所有这一切都是创建一个region对象并将其与location对象相关联。
