Tonic — A RESTful Web Application Framework

TonicVia [Sam

is a very promising RESTful web application framework for PHP. If you are doing web development in PHP I definitely suggest you take a closer look.

I am always interested in how RESTful behaviors are implemented, regardless of the language and environment used so I went and had a little peek at the docs. I noticed a couple of details that I think are interesting and might be relevant to the RESTful Rails work going on now.

Controller–Resource Type Relationship

Tonic seems to define a controller class (though they call them something different) per resource type. This is different than any of the rails approaches I have seen, which combine the code to support multiple resource types into a single controller class. It is not clear to me, from the documentation I have read so far anyway, exactly how collection resources with addressable members are handled. For example, if http://store.example/products/ is a collection of all known products and http://store.example/products/magik-eight-ball is a particular product how does Tonic handle route those requests to the appropriate resource controllers?

Resource Modifier Resources

Tonic uses the concept of editor and delete resources to manage the modification and deletion of resources. This is quite similar to Charlie’s approach. This is at least one significant difference. It appears–but I am not sure about this so correct me if I am wrong–that you post to the editor to update the resource. From an REST standpoint that is fairly unclean but it would make handling bad form data issues Charlie talked about a lot easier. And if you also supported PUT on the target resource you app would still be RESTful.

  1. I may be misunderstanding what you are saying, but destructive operations (Updae/Delete) should not be handled with GET.

    A lot of people learned this lesson the hard way when Google unveiled their caching/proxy service.

  2. A Brown, The modifier resources are just the pages with the forms for editing or deleting a resource. The results of filling out the form are sent via POST, PUT or DELETE to the appropriate resource for the destructive operation.
