factory_bot / factory_girl添加belongs_to的语法

Question

我有以下模式：

class SecondaryIabCategory < ApplicationRecord
  has_many :sites, foreign_key: :secondary_category_id
  belongs_to :primary_iab_category
end

以下是有问题的工厂的评论：

  factory :primary_category, class: PrimaryIabCategory do
    name 'Arts & Entertainment - yaddah'
    value 'IAB1-some'
  end

  factory :another_primary_category, class: PrimaryIabCategory do
    name 'Games are cool! - dabbah'
    value 'IAB1-other'
  end

  factory :secondary_category, class:  SecondaryIabCategory do
    # here is the problem - what's the correct syntax?
    primary_iab_category another_primary_category
    name 'Test Secondary Cat'
    value 'xxyy'
  end

我得到了错误信息：

NoMethodError: undefined method `another_primary_category=' for #<SecondaryIabCategory:0x00007f925c64e0d8>

我已经有几个月没有使用FactoryBot/Girl了，所以我不确定它的语法是什么。有什么想法吗？

Answer 1

尝尝这个

factory :secondary_category, class:  SecondaryIabCategory do
  association :primary_iab_category, factory: :another_primary_category
  name 'Test Secondary Cat'
  value 'xxyy'
end

鲁比多是非常详细的
