我有一个帐户和一个用户模型。使用Account: has_one :owner, class_name: 'User'和has_many :users。
我的第一个规格是失败的：
1) User has a valid factory
Failure/Error: Unable to find matching line from backtrace
SystemStackError:
stack level too deep
# /usr/local/rvm/gems/ruby-2.1.1/gems/activerecord-4.1.1/lib/active_record/connection_adapters/abstract/database_statements.rb:222
我正在寻找一个循环，但我没有看到它！用户工厂调用调用所有者工厂的帐户工厂......有什么问题吗？
## /spec/models/user_spec.rb
require 'rails_helper'
RSpec.describe User, :type => :model do
it "has a valid factory" do
expect(FactoryGirl.create(:user)).to be_valid
end
end
我的2家工厂：
## /spec/factories/accounts.rb
require 'faker'
FactoryGirl.define do
factory :account do
name { Faker::Company.name }
subdomain { Faker::Internet.domain_word }
association :owner, factory: :owner, strategy: :build
end
end
## /spec/factories/users.rb
require 'faker'
FactoryGirl.define do
factory :user do
firstname { Faker::Name.first_name }
lastname { Faker::Name.last_name }
email { Faker::Internet.email }
password { Faker::Internet.password(6) }
association :account, factory: :account, strategy: :build
role {"employee"}
end
factory :owner, class: User do
firstname { Faker::Name.first_name }
lastname { Faker::Name.last_name }
email { Faker::Internet.email }
password { Faker::Internet.password(6) }
role {"owner"}
end
end
编辑，添加2个模型：
class User < ActiveRecord::Base
include ActiveModel::Dirty
include PublicActivity::Common
##
# user ROLES can be owner, manager or employee
ROLES =%w[owner manager employee]
devise :invitable, :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable
acts_as_messageable

然后去......
答案 0 :(得分：0)
我认为这只是因为before_create回调：
User型号：
def default_values
self.active ||= 'true'
self.save
true
end
尝试替换为：
def default_values
self.active ||= 'true'
end
您不需要手动拨打save（因为它会循环播放您的回调）
