Cannot use "Application" as a model?

I tried creating an application that has an "Application" model. This seems to collide with the "ApplicationController" defined in application.rb.

For example... rails appgoboom cd appgoboom script/generate scaffold Application name:string script/console Loading development environment (Rails 2.2.2)

Application.find(:all)

LoadError: Expected /home/rkrueger/source/rails/appgoboom/app/ controllers/application.rb to define Application   from /usr/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_support/dependencies.rb:428:in `load_missing_constant'   from /usr/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_support/dependencies.rb:77:in `const_missing'   from /usr/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/ active_support/dependencies.rb:89:in `const_missing'   from (irb):1

I get the same error when running the application using script/server: "Expected /home/rkrueger/source/rails/appgoboom/app/controllers/ application.rb to define Application"

I've been trying to go through the thesaurus in my head to find other names to use than "Application", but honestly Application is what I want. Everything else sounds lame...

That's about right. Because there is an application.rb in an appropriate place in the search path Rails may find that file and try to load it first. While you might be able to fiddle with those so that rails found your model class first that would then probably screw things up when Rails is actually looking for ApplicationController. You might be able to get round this by just explicitly loading your model rather than relying on the magical loading

Wait for Rails 2.3 where ApplicationController will live in application_controller.rb :slight_smile:

Lame! :stuck_out_tongue:

Thanks for the tip Frederick, would you be able to clue me into where I can read about doing that? I'm too new at this to know how to do anything other than "magical loading" heh.

Yeah thought about that, I wasn't sure if Edge was too shaky right now to try and jump on that though.

Put your model class in something called not application.rb. Then use require_dependency to require that file. Where exactly you do
that is up for some debate but you could start with the bottom of
application.rb (as in where ApplicationController sits)
