I’m in an argument with a developer I’m working with. We’re developing an app with no API and quite a bit of AJAX. He wants to use restful controllers everywhere. This annoys me. Right now we have one page that is referencing 4 different restful controllers with views and partials all over the place. To me it makes more sense to put all the actions you need for one page into one controller so it’s coherent and easy to debug. I think it could just be that his nazi perspective on mapping controllers directly to models could be the problem… I’ve read some different stuff about restful, but I haven’t been able to find anything that’s a simple clear explanation of WHEN and WHY to use them? Who here is the jackass? 🙂 John ---

Ok, let’s start with the fact, that there is no perfct way and much may depend on details of your app. > To me it makes more sense to put all the > actions you need for one page into one controller so it’s coherent and > easy to debug. Nope, this would maybe make sense, if you could be 100% sure, that those actions will never be used in any other view. Otherwise the mapping model/controller is much more likely to be still helpful if your app grows and gets more complex. Think you have a show action for whatever model (say a product as axample). As long as there is only one central page that shows this resource, you will find it in the controller where you expect it. But if you add more views and allow to display this product from different places in your app, you’ll start searching for your action. With model based REST resources the show action for the product will be in the products controller. And this way to see things is more object oriented. You have a resource and somehow ask this resource to display itself, update itselft and so on. As mentioned, there may be lots of examples to show cases where your view may be better, but in general REST is right… ---

REST isn’t the same thing as CRUD, although having your CRUD-centric controllers and actions be RESTful is popoular in the Rails community.

Luke, I’m your father, Give in to the Rest side of the force … I heard this same kind of argument at a Restful session at Railsconf on Saturday at the guy that was arguing your point was generally declared to be half horse and half donkey, if that answers the last question. There is never a complete right and wrong and Rest can be done poorly, but using Rest is always more correct than what you are suggesting. It’s change, It’s painful. You are not used to it. You are resisting the correct thing. Your argument is similar to arguing against OO because it is new and painful. Get over it, go with Rest, Learn about it and do it correctly. ---

I hope you’re responding to the original post, not my reply. 🙂 If not, I wasn’t arguing against REST. I was pointing out that people often assume that REST and CRUD-centricity are the same thing. What I assumed to be implicit in my post, but perhaps should have made explicit, is that REST always makes a great deal of sense, but CRUD-centricity does not.
