Ruby on Rails 中模型的完全限定名称是什么?
如果我有 2 个不同的类，名称为 User，在 FooModule 中说一个，在 app/models/user.rb 中说另一个作为模型>，如何确保我使用的是正确的?
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?
FooModule::User 肯定会给我正确的.
我想问的是:如果 ApplicationController 包含 FooModule，User 或 ::User 仍会给我 app/models/user?
What I had meant to ask was:
If ApplicationController includes FooModule, would User or ::User still give me app/models/user?
使用他们的全名，FooModule::User 和 ::User
Refer to them using their full names, FooModule::User and ::User
一般来说，如果你只使用 User，它应该假设你的意思是 ::User，除非你在 FooModule 中.无论哪种方式，请使用 FooModule::User 或 ::User 来确保.
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.
