[Deprecated] DMZ 1.5.3 (DataMapper OverZealous Edition)

[quote author="ben_co" date="1250950981"]I know it's a bit different with the natural DMZ way but I was wondering why we should create an DMZ model instance to do bulk operations for instance. Moreover, if we were totally working in PHP5, the bulk update could be declared as a static method.

Code:

DMZModel::bulk_update($params);

But now you've lost the ability to use the large amount of built-in functions. How do you handle relationships? How do you specify what is updated without reinventing the wheel? In your static example, there is no way to specify which rows need to be updated.

By using an extension like my example, you get to write code like this:

Code:

$user->articles->bulk_update(array('have_read', TRUE));

$newstype = new Type(3);
$twoweeks = 1209600;
$articles->where_related('type', $newstype)->where('created <', time()-$twoweeks)->bulk_update(array('oldarticle', TRUE));

It might be better to name it "update_query" or "update_all", or even just simple "update". I'll have to think about it, because I can see it's use more and more. The only thing my example doesn't handle (currently) is allowing you to easily use functions (they must be specified manually).

Are you simply not wanting to create the object manually? It's only one line to create the object, and it opens a wealth of options. And there is no additional overhead in using the standard DataMapper model for updates. You have to instantiate at least one copy of every model just to figure out what the table name is.
