To Module or Not to Module? 07-03-2010

So, the other day I ran into a problem. I have a simple admin? function that I use to tell whether I can show admin links and it also restricts access to admin sections of the site. So I have a function which I need to use in both views and controllers. The problem is that I don't have a really good place to define this. Since if I put it in an application_controller, I won't be able to use it in the views and if I put it in the application_helper I won't be able to use it in the controllers.

The only thing I could think of was putting it in both. Which is dumb b/c when I have to come back and change it later, I'll forget to change it in both places.

I ended up making a module called Auth and requiring that in both my application_controller and my application_helper. The examples I saw used it as follows:


However I went in favor of:


Since that makes it a little more clear that this isn't a model.
