Rails 3 引擎可以从其父应用程序访问模型吗?

问题描述：

我有一个 Rails 引擎，我想访问父模型.那可能吗?如果是这样，我该怎么做?

I have a Rails Engine and I want to access the parents models. Is that possible? If so, how would I do it?

答

我没有找到任何关于它的官方文档，但您仍然可以这样做:

I didn't find any official documentation about it, but here's how you could still do it:

tests = ::Test.all

它将返回来自父应用测试模型的所有测试.

It'll return all tests from the parent app Test model.
