...I'd like to mount multiple versions of the same engines, and have those instances independently configured. Something along the lines of...

Rails.application.routes.draw do

推荐答案

我的直言不讳，因为第一个实现的命名空间会踩到第二个实现的脚步.虽然既然文件是相同的，但我想那没关系吗?你到底是怎么过的?

My gut tells me no, because the namespacing of the first implementation would step on the toes of the second. Though since the files would be the same I guess that wouldn't matter? How did you get on in the end?
