Question

我遇到了依赖销毁功能的一些问题。模型如下。

Company.rb

has_many :company_users, dependent: :destroy
has_many :users, through: :company_users, dependent: :destroy

CompanyUser.rb

belongs_to :company
belongs_to :user

User.rb

has_one :company_user, dependent: :destroy
has_one :company, through: :company_user

当我删除公司时，它需要删除公司用户以及用户。

目前只删除公司用户。关于如何解决这个问题的任何想法？

Answer 1

这将有效，并在内容中找到已完成的更改

class Company < ActiveRecord::Base
    has_many :users, through: :company_users #removed dependent destroy
    has_many :company_users, dependent: :destroy 
end

class User < ActiveRecord::Base
    has_one :company_user
    has_one :company, through: :company_user
end

class CompanyUser < ActiveRecord::Base
    belongs_to :company
    belongs_to :user, dependent: :destroy #added dependent destroy
end

日志

DELETE FROM "company_users" WHERE "company_users"."id" = ?[0m  [["id", 4]]
DELETE FROM "users" WHERE "users"."id" = ?[0m  [["id", 4]]
DELETE FROM "companies" WHERE "companies"."id" = ?  [["id", 4]]

有很多通过，依赖破坏的问题
