FWIW I find it best to decouple the model and the database. Instead, I have the model which knows almost nothing about the underlying persistence and one or more data loading/saving classes. The saving classes can be thrown the model and database connection (usually a Zend_Db_Adapter_Abstract instance) usually because the calling code knows it loaded that object through the same class. Allows us to cleanly switch between database schemas or even load representations from external sources such as a CRM.

@Carlos Aguado: Exactly. The way I’ve preferred to develop MVC applications (desktop, Web, whatever) is to use a view that has near-zero intelligence – it just serves as a mapping from a logical/functional API (exercised by the controller) to the code needed to paint the interface. Since the controller is basically a traffic cop (take this command input, get the appropriately-massaged data from the model and hand it off to the view), that means that most of the “interesting” code goes into a “heavy” model (which itself is a set of interfaces with various domain classes in between. This makes it easy to, say, change application types. (here’s a Web site; here’s a set of Web services; here’s a desktop app…. see how much gets reused?) It’s also easy (easier) to make heart-transplant-level architectural changes. Client wants a new database? Fine. They’re booting their old ISP and the new one has several major differences? Sorted.

Of course, MVC is also The Poster Child™ for TDD and CI, but that’s a whole other set of posts…

Doctrine 2 is very different from Doctrine 1 and it allows you to have Plain Old PHP Objects instead of Active Records in your model (a la Hibernate). Very beneficial. :)

“In a nutshell, the model handles data: storing it, retrieving it, filtering and validating it, and providing access to it.”

Good to hear that filtering and validation are to be performed by the model. This is precisely my idea, as filtering and validation are also, somehow, “domain logic”. I had a long discussion about this with people that stated that filtering and validation are view’s tasks. I don’t agree with that at all…

Thanks for the article!

A nice overview of the core ideas. Thanks!

The source code of DASPRiD’s site contains an interesting implementation of an injection-container-based service architecture that calls mappers which build models.

Site itself: http://www.dasprids.de/
Source code: http://site.svn.dasprids.de/trunk

The App library, in particular, is completely generic: drop it into a project, add a little bootstrap, and start creating your own services, mappers, and models.

I’ve just done one, though I fear I might have mucked it up a bit. More experienced hands would no doubt do a better job with it. I’ll probably try a little more experimentation to develop familiarity with custom mappers, but I feel that there might some Doctrine in my future).

Cheers!

Models in Zend Framework | Matthew Turland…

A question that frequently comes up in my interactions with other developers about Zend Framework is how to approach designing models. There’s a small collection of resources and advice that I generally give on the subject, so I thought I’d write up a …
