I have a bunch of controllers with methods that render the index view. This results in me writing `render :index` at the end of the majority of methods. Here's an example

```
def index
  @models = Model.find(:all)
end

def new_models
  @models = Model.find_by_new(true)

  render :index
end

def old_models
  @models = Model.find_by_new(false)

  render :index
end

```

Ideally, I would just move the render code into an after filter, but as the controller makes a call to render before going to the after filter that's not an option.

I have a large number of controllers like this so a solution would remove a lot of repeated code.

This app is currently still Rails 2.3, however, it will be upgraded to Rails 3 in the next month or two. So while I would prefer a technique that works on 2.3, Rails 3 only solutions would still be appreciated.
