如何在rails4中编写更新所有有条件查询

Question

我想要类似于rails查询:

UPDATE users SET name="test" WHERE name="test1"

Answer 1

User.update_all({name: 'test'},{name: 'test1'}) # deprecated since Rails 4

要么

User.where(name: 'test1').update_all(name: 'test')

Answer 2

User.where("name like 'test1'").update_all("name = 'test'")
