Best way to share a plugin between different Rails application

Hello list,

Ok, so this issue might be a topic for a design pattern that has already
been discussed a lot around the Rails community, but the information I
found
is too disperse, and I would like some specific advice if possible.

I have a project that consists of several Rails applications. Actually
we
got this project with the “please save me” metadata. We are refactoring
it
to follow best practices and have a better maintenance factor.

So, each rails app, from the client perspective, is a “module”. Each app
implements a different part of the system, but still needs artifacts
from
the others (higher-level artifacts, that are common between all of
them),
and here’s where the problem lies, everything is duplicated across all
these apps: models, controllers, helpers, views, migrations. A true
maintenance hell.

So, what I’m politely asking here is, the ways to solve this Wet
problem,
i.e, DRYing it up.

The way I thought to approach the problem so far is to use Rails engine
*to
package all the artifacts (models, controllers, migrations, and any
other
class/asset) in one Rails plugin. So far so good. It is a good proven
solution, since Rails engine has been around for quite some time and has
proven to work well.

What I still don’t know is how to share this plugin among the apps. I
see
two ways:

  1. As a git submodule. So, the plugin would be in vendor/plugins, but as
    a
    git submodule;
  2. In a central location, still version-controlled of course, but the
    sharing wouldn’t be done via git submoduling, but instead, I would tell
    each
    application to load this additional plugin from this outside location.

I would like some advice on this, any suggestion/idea is very welcome!

Thanks,

Marcelo.

I’m not sure it really matters though…
