Rails - Delete record with condition by using destroy_by

Before Rais 6, if you want to delete an user with name Alice, you could do this way:

user = User.find_by name: "Alice"
user&.destroy

This way is quite long, so Rails 6.0 provides method destroy_by (and delete_by) as an alias for old way to delete a record with condition.

User.destroy_by(name: "Alice")

No optimize for code here, just an short way to call. You could view more detail code is in this pull request.
