Breaking a large rails app into smaller apps? [closed]

Question

I have a Rails app with 600 models and that will soon grow to 800-1000. I'd like to segment the rails app so that only certain models get loaded and therefore act as a separate app, but all share the same base models. Is there a standard practice for doing this?

EDIT: I am on 2.3.8

EDIT 2:

The problem is that many models are similar, but different just enough that it warrants writing a new class, i.e. the logic required to put it all in one model would be horrendous. Some of the models could be moved out into rake tasks or the lib directory, but only about 30 or so. Some are abstract classes that act as parents of one arm of the model tree. However, most relate to database tables. I am thinking about at deploy time segmenting parts of the app into plugins via Engines so that one app can only handle one set of models (they are independent) but so that I can keep them all together in development and in one git repo for convenience. I"m going to go down this route unless someone else has a better idea, and I'll post back to let you know how it goes.

Answer 1

Dude, thats a pretty insane amount of models... anyways for handling complex logic and easily reuse them across other projects I would recommend to you the engines (from 2.3+ is part of Rails).

With that in place you can split your model in different modules (engines)
