Due to hosting constraints I am porting an ASP.NET MVC to Ruby On Rails. In my ASP.NET application I had 2 web applications. One for the Admin section, and one for the public section.
Both referenced a class library that held all my Business Logic and Data.
Now I want to accomplish the same thing in Ruby On Rails. How do I use my model in two applications?
First shot: put the business logic and associated models in a plugin.
Second shot: use SVN externals or Git submodules to replicate the exact code in your app, for example under APP_ROOT/lib/ and then require it in your environment.
And last... why not putting the admin and public section in the same app?
I would create a plugin. Call it IceheatSharedLogic or something. Add the model and supporting code to the plugin and commit it to its own source control location. Add that plugin via svn:externals or equivalent to both apps.
But given your use case, is it really necessary to have 2 apps? It seems that would make things complicated if you ever needed any interaction between them (such as putting an edit link on a page, if you are logged in as an admin).
