如何创建工厂女孩has_and_belongs_to_many协会 [英] How to create has_and_belongs_to_many associations in Factory girl

问题描述

由于以下

class User < ActiveRecord::Base
  has_and_belongs_to_many :companies
end

class Company < ActiveRecord::Base
  has_and_belongs_to_many :users
end

你怎么定义的公司和用户，包括双向关联工厂？这是我尝试

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

现在我尝试

Factory :user

也许并不奇怪这会导致一个无限循环的工厂递归使用对方来定义自己。

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

更令人惊讶的我还没有找到如何做到这一点的任何地方一提的，是有确定必要的工厂或我在做某种根本性错误的模式？

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?
