[Deprecated] DMZ 1.5.3 (DataMapper OverZealous Edition)

Edit: corrected that it was 1.5.1 that has the new local/global extension settings.

[quote author="Mirage" date="1251440468"]Does each model receive it's own instance of an extension or is there only a single instance of an extension for all models that use it (or globally configured).[/quote]

In 1.5.1, there is one instance if created globally, and another, different instance for each type of model if created locally.

So you could have a globally created json, a different json on Users, and a third json on Groups. Not that you would ever want to do that.

Each individual instantiated class does not get its own copy. This would be inefficient, I think, since someone could load up large dataset and end up with 100s of extra objects in memory that aren't even being used.

It doesn't say it in the docs, but extensions are intended to be mostly stateless, except for the initial configuration.

If you need to track a per-object value, I recommend adding properties to the model directly.

For example:

Code:

// in extension
function something_cool($object, $param) {
    // store the current time for tracking
    $object->_my_extension_start_time = time();
    ...

Use something highly unique for the value so it won't get in the way.

Yep, that fixes it. Though if I’m reading you correctly it’s still broken in AR?

See my edit, I made a typo. The bug was only in DMZ.

PS: You said the docs don't mention the prefix earlier, I'm pretty sure there's a huge yellow box on this page that does just that, or am I misunderstanding what you wrote?
