Joe’s Amazing Technicolor Weblog

I have a new project coming up that seems like a great fit for Ruby on Rails, particularly the RESTful interfaces that have gone in over the last year. However, the typical questions about using Rails apply here: I’m not sure how well the project’s hosting environment will support Rails, and collaborators aren’t as familiar with it. Thus, it seemed like it might be worth another look at options on the PHP side of things. I keep hearing that CakePHP is Rails-inspired and has many of the same advantages, so today I’ve taken the stable version (1.1.8.5850) for a spin, letting the Cake manual’s blog tutorial get me started. Here’s what I’ve noticed about CakePHP development as practiced in the tutorial — maybe there’s better ways to do things & the tutorial just isn’t mentioning them?

• No migrations; you have to generate the DDL on your own, both initially and for any subsequent modifications. Also, no model or controller generators. It’s definitely nicer to just do script/generate scaffold post title:string body:text; rake db:migrate and be off to the races — from Rails 1.2 on, those races include the whole REST business. To be fair, there is a one off reference to ‘bake’ scripts in the CakePHP manual, but no pointers on what those are, or where they live, and the website isn’t much clearer.
• No TDD. Woah. That’s, like, half the advantage of Rails — automated testing is right there in your face, and is firmly entrenched in the community.
• PHP code is not quite as elegant as Ruby. For example, generating a link to delete a post looks like this: $html->link('Delete', "/posts/delete/{$post['Post'][id']}", null, 'Are you sure?' ). Can you spot the syntax error? Probably you can, but it took me a good few minutes. The Rails equivalent would be
  link_to "Delete", { :action => "delete", :id => @post.id }, :confirm => "Are you sure?", :method => :delete
• A lack of the experiences baked into Rails. For example, after the Google Web Accelerator fiasco, it became common practice to make all links to destructive actions happen via POST, which can be done via link_to’s :method parameter. Compare to the GET-powered delete link above, straight from the Cake tutorial.
• I miss my vim & rails integration, which makes creating and navigating the various files a breeze. (Glad I went to the trouble of making that a link, as it got me re-reading the plugin’s about page, and I saw the parts about partial extraction and migration inversion, neither of which I’d noticed before)

On the upside, using CakePHP sure beats writing a CRUD-heavy PHP application from scratch. One of my current projects, a completely custom contact management application, would be in much better shape if it were using CakePHP instead of the project-specific ORM I cobbled together — I’m going to have to give conversion of that project to CakePHP some serious thought.

But is CakePHP a DSL for the web in the sense that Rails is? Not yet.
