rails 如何迁移 find_all_by_

Question

Hi I migrate an app from Rails 2 to Rails 7.04.您好，我将应用程序从 Rails 2 迁移到 Rails 7.04。

I don't see how to rewrite:我不知道如何重写：

self.accepted_roles.find_all_by_name(role_name).any? { |role| role.users }

users = self.accepted_roles.find_all_by_name(role_name).collect { |role| role.users }

users.flatten.uniq if users

I think self.roles.where("name="role_name).find_each but .any?我认为self.roles.where("name="role_name).find_each但.any? and .collect和.collect

I don't find Rails 2 documentation.我找不到 Rails 2 文档。 Help is welcome欢迎帮助

Answer 1

I think that .where() is what you are looking for.我认为.where()就是您要找的东西。
