使用一个查询在Rails中同时使用ActiveRecord更新多个记录？

Let's suppose I have a table called 'user_products' and a corresponding model called UserProduct in my Rails application. I also have a field called 'is_temporary' in my table. Now suppose I want to run a query like this but using the ActiveRecord abstraction layer:

假设我的Rails应用程序中有一个名为“user_products”的表和一个名为UserProduct的对应模型。我的表中还有一个名为'is_temporary'的字段。现在假设我想运行这样的查询，但使用ActiveRecord抽象层：

UPDATE user_products SET is_temporary = false WHERE user_id = 12345;

Is there a way I can do this using ActiveRecord? Maybe something along the lines of

有没有办法使用ActiveRecord做到这一点？也许有些事情

UserProduct.find_by_user_id(12345).update_attributes(:is_temporary => false)

I'd like only one query to be run for this to happen.

我想只运行一个查询才能实现。

3 个解决方案

#1

UserProduct.update_all({:is_temporary => false}, {:user_id => 12345})

This is an old post. I updated this in case someone checks it :) (Rails 4)

这是一个老帖子。如果有人检查它我更新了这个:)（Rails 4）

DEPRECATION: Relation#update_all with conditions is deprecated. Please use Item.where(color: 'red').update_all(...) rather than Item.update_all(..., color: 'red').

So the query will be

所以查询将是

UserProduct.where(:user_id => 12345).update_all(:is_temporary => false)

Cheers

干杯

#3

UserProduct.update_all({:is_temporary => false}, {:user_id => 12345})

Although beware: this skips all validations and callbacks, since no instance of UserProduct will ever be instanciated.

虽然要注意：这会跳过所有验证和回调，因为不会实例化UserProduct的实例。

UserProduct.update_all({:is_temporary => false}, {:user_id => 12345})
