如何在工厂女孩中创建 has_and_belongs_to_many 关联 [英] How to create has_and_belongs_to_many associations in Factory girl

问题描述

鉴于以下内容

class User < ActiveRecord::Base
  has_and_belongs_to_many :companies
end

class Company < ActiveRecord::Base
  has_and_belongs_to_many :users
end

如何为公司和用户定义工厂，包括双向关联?这是我的尝试

how do you define factories for companies and users including the bidirectional association? Here's my attempt

Factory.define :company do |f|
  f.users{ |users| [users.association :company]}
end

Factory.define :user do |f|
  f.companies{ |companies| [companies.association :user]}
end

现在我试试

Factory :user

也许不出所料，这会导致无限循环，因为工厂递归地使用彼此来定义自己.

Perhaps unsurprisingly this results in an infinite loop as the factories recursively use each other to define themselves.

更令人惊讶的是，我在任何地方都没有提到如何执行此操作，是否有定义必要工厂的模式，或者我在做一些根本错误的事情?

More surprisingly I haven't found a mention of how to do this anywhere, is there a pattern for defining the necessary factories or I am doing something fundamentally wrong?
