FactoryGirl Rails 参数错误

Question

我在使用 FactoryGirl on Rails 时遇到了一个奇怪的问题/错误：

ArgumentError: wrong number of arguments (given 1, expected 0)
  /Users/bintoy/ruby-apps/tradegecko-exercise/exercise-app/spec/factories/object_records.rb:3:in `object_id'

注意：这不是重复的问题：Why am I getting FactoryGirl wrong number of arguments error? - 我已经尝试了很多可能的解决方案，例如手动加载或注意到 FactoryGirls 和 Spring 的问题。但它们都不起作用。

设置是数据库基于MongoDB（Mongoid映射器），这里是涉及的文件：

app/models/object_record.rb

class ObjectRecord
  include Mongoid::Document

  validates_presence_of :object_id, :object_type, :timestamp, :object_changes
  validates_uniqueness_of :timestamp, :scope => [:object_id, :object_type]

  field :object_id, type: Integer
  field :object_type, type: String
  field :timestamp, type: DateTime
  field :object_changes, type: Hash

end

spec/features/user_searches_spec.rb

require 'spec_helper'
require 'rails_helper'

    feature 'User searches on table' do
      before :each do
        FactoryGirl.create(:object_record)
      end

      scenario 'with an object id', js: true do
        input_a_search '1'

        expect(page).to have_css(".sorting_1", :text => "1")
        save_and_open_screenshot

      end

      def input_a_search(search_word)
        visit object_records_index_path
        find('input[type=search]').set(search_word)
      end
    end

spec/factories/object_records.rb

FactoryGirl.define do
    factory :obect_record do
        object_id   1
        object_type "ObjectA"
        timestamp 1465748715
        object_changes ({:property1 => "val1"})
    end
end

spec/support/factory_girl.rb

    RSpec.configure do |config|
      config.include FactoryGirl::Syntax::Methods
    end

spec/spec_helper.rb

RSpec.configure do |config|

  config.after(:all) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:suite) do
    FactoryGirl.reload
  end


  config.expect_with :rspec do |expectations|

    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|

    mocks.verify_partial_doubles = true
  end

end

spec/rails_helper.rb

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)

abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'spec_helper'
require 'rspec/rails'

require 'capybara/rspec'
require 'capybara/rails'

require 'capybara/poltergeist'
Capybara.javascript_driver = :poltergeist

require 'factory_girl_rails'


Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

RSpec.configure do |config|
  config.include Capybara::DSL

  config.infer_spec_type_from_file_location!

  config.filter_rails_from_backtrace!

end

编辑： 出于随机尝试调试它，我尝试在工厂中省略 object_id 的参数以查看会发生什么：

FactoryGirl.define do
    factory :obect_record do
        object_id   
...

但是我从 Rspec 得到了这个失败/错误消息：

  1) User searches on table with an object id
     Failure/Error: FactoryGirl.create(:object_record)

     ArgumentError:
       Factory not registered: object_record
     # ./spec/features/user_searches_spec.rb:8:in `block (2 levels) in <top (required)>'

Answer 1

ruby 中有一个现有的object_id 方法：您的工厂正在调用该方法，而不是通过工厂女孩中创建属性的method_missing 代码。

方法缺失钩子只是为了方便，可以直接调用添加属性

add_attribute :object_id, 1

此外，您的工厂定义似乎有错字 (obect_record)。

因为object_id 是核心 ruby​​ 方法，所以使用该名称可能会遇到其他问题。
