如何在活动记录中删除？

我看着活动记录查询，它不会对删除，我可以看到任何东西。

删除按id，

删除像现在的对象： user.remove ，

可以删除基于where子句？

这是破坏和 destroy_all 方法，如

  user.destroy
User.find（15）.destroy
User.destroy（15）
User.where（年龄：20）.destroy_all
User.destroy_all（年龄：20）
 

另外，您可以使用删除和 DELETE_ALL 将不执行：before_destroy 和：after_destroy 回调或任何相关的关联选项

How do you delete in active record?

I looked at Active Record Querying and it does not have anything on deleting that I can see.

Delete by id,

Delete the current object like: user.remove,

Can you delete based on a where clause?

It's destroy and destroy_all methods, like

user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)

Alternatively you can use delete and delete_all which won't enforce :before_destroy and :after_destroy callbacks or any dependent association options.
