一次性删除 Rails model 及其关联？ 新手问题
[英]Delete Rails model and its associations in one action? NEWBIE question
问题描述
I have a really simple association with the Devise user object where each user has one Profile (with more application specific stuff...) I am having no issues creating the User object and accessing the user and its profile object. 
I have a really simple association with the Devise user object where each user has one Profile (with more application specific stuff...) I am having no issues creating the User object and accessing the user and its profile object. ie, @user.profile即@user.profile
However, I'm having an issues when I try to delete the profile object - I'd assume that when I delete the User object, it would also delete each associated object.但是，当我尝试删除配置文件 object 时遇到问题 - 我假设当我删除用户 object 时，它也会删除每个关联的 object。 The association in my User object is like so accepts_nested_attributes_for:profile, :allow_destroy => true我的用户 object 中的关联就像这样接受_nested_attributes_for:profile, :allow_destroy => true
The has_one and belongs_to associations are set on both the User and Profile objects. has_one 和 belongs_to 关联在 User 和 Profile 对象上都设置了。 Maybe the issues is in Devise code - I'm stumped.也许问题出在 Devise 代码中——我很难过。 An idea what I'm missing here.一个想法我在这里错过了什么。

You need to specify :dependent on the association:您需要指定:dependent于关联：
has_one :profile, :dependent => :destroy
