Question about putting code in application.rb

hi, i have 4 different controllers that are basically doing the same
thing but just passing different parameters to the model functions. can
i just place all the code in the application.rb file?

so when an action comes in from a view, it goes to the controller, and
then to the application.rb, and then passed to the model?

Yes.

Not exactly.

All controllers inherit from the class ApplicationController which
resides your application.rb.

So any action will be handled by your controller unless it doesn’t have
that action defined. If your controller has no action, it will use any
action from it’s parent’s class, in this case ApplicationController.

It will never go to the model searching for methods, ever.

In short, any functionality you want it all controller, put in
application.rb.

If you want this functionality in all controllers, then it should go in
application.rb.

If you want it in only some controllers but not others, you could create
a
new controller

class AdminController< ApplicationController
before_filter :admins_only

end

Then inherit from that instead

class SomeOtherController < AdminController

end

You could also experiment with using modules to share code between
controllers.
