rspec 预期 #count 已更改为 1，但已更改为 0

Question

我的 locations_controller_spec.rb 中有以下内容：

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

我的地点工厂有：

FactoryBot.define do
  factory :location do
    name              'MyString'
    hours_operation   'MyString'
    abbreviation      'MyString'
    address_1         'MyString'
    address_2         'MyString'
    city              'MyString'
    state             'MyString'
    postal_code       1
    phone             'MyString'
    fax               'MyString'
    association       :region
  end
end

我为数据库设置了种子以解决区域需要存在的问题，但现在我得到：

Admin::LocationsController create should create the record
 Failure/Error:
   expect do
     post :create, params: { location: FactoryBot.attributes_for(:location) }
   end.to change(Location, :count).by(1)

我错过了什么？位置正在存储。

编辑：这是导致问题的控制器：

def create
 @region = Region.find(params[:region_id])
 @location = @region.location.new(location_params)
 flash[:notice] = 'Location created successfully'if @region.location << @location
 respond_with @location, location: admin_locations_path
end

Answer 1

我弄乱了控制器的创建方法。一旦我将其切换回来，它就起作用了：

def create
 @location = Location.new(location_params)
 flash[:notice] = 'Location created successfully' if @location.save
 respond_with @location, location: admin_locations_path
end

rspec 预期 #count 已更改为 1，但已更改为 0

rspec expected #count to have changed by 1, but was changed by 0
