If I have 2 different classes with name User, say one in FooModule and other as a model in app/models/user.rb, how do I make sure I am using the correct one?
如果我有两个不同的类，名称用户，一个在FooModule，另一个作为模型在app/models/ User。rb，我怎么确定我用的是正确的?
EDIT: FooModule::User would definitely give me the correct one.
编辑:FooModule::用户一定会给我正确的。
What I had meant to ask was: If ApplicationController includes FooModule, would User or ::User still give me app/models/user?
我想问的是:如果ApplicationController包含了FooModule, User还是会给我app/model / User吗?

Refer to them using their full names, FooModule::User and ::User
使用他们的全名:FooModule: User和:User
Generally if you just use User, it should assume you mean ::User, unless you are within FooModule. Either way, use FooModule::User or ::User to be sure.
通常，如果您只是使用用户，它应该假定您的意思是::用户，除非您在FooModule内。无论哪种方式，都要使用FooModule::User或::User来确保。
