Just wondering if it’s possible to have a model named Application in  
rails 2.0. It seems to be blowing up when I try, and I’m wondering if  
there’s a workaround. Thanks!

Probably asking for trouble seeing as application\_controller lives in  
application.rb (for (from what I gather) largely historical reasons.

A model named Application is going to map, by default, to a controller  
named  
application\_controller. And that name’s already taken. You can work  
around  
it if you really want to, but you’ll find it a lot easier to just name  
your  
model something else. MyApplication, InHouseApplication, etc.

I’d pass on using Application as a model name. I’d become familiar with  
the conventions of Rails and make sure that I didn’t name any models  
Application or Layout for starters

Might work, but it’s gonna be trouble-prone. Rails is convention-based.  
The conventions are ‘baked-in’. Unscramble an egg 😉

Can’t he use a named route without any problems?
