Re: CakePHP 1.3 - ClassRegistry::init('Model')/loadModel() constructs EVERY related model (multiple times) too?!

Yes, that is the way it works. And I had a lot of problems with that as well

You can use a plugin like this to avoid loading all models: https://github.com/lorenzo/lazy_loader

Upgrading your application would be the best idea, though

Hey guys,

I'm wondering if anyone has a clue on this one, but I need to check if this is the standard behavior or not in CakePHP 1.3.

Let's say I want to create a model anywhere in my app. Besides a lot of other options, I could do this with:

$Post = ClassRegistry::init('Post');

When I trace the call stack of my function, I see that cake invokes EVERY related model (via belongsTo, hasMany etc.). And it is doing it recursive, so when I hit a second related model with a back-connection to the first model, it constructs them another time all the way trough.

I have an app on Cake 1.3 with about 150 models, which are nearly all related to each other via model-paths/associations. When I trace the call stack and check what models get constructed, it will end up in constructing nearly 600 (!) model-classes (some models are instantiated at least 35 times).

I checked this with Cake 2, and it behaves completely different. Only the models targeted within finds or accessing data from other models, those models are instantiated. The only thing I know of for the moment is removing those relations and use on-the-fly bind/unbind within all actions, but this would be a hell lot of work to do (and easier to migrate the whole app to cake2).

So my question is:

Is this normal for CakePHP 1.3 to create ALL related models/classes as well? Did anyone of you had similar problems when the app grew and you had more than 100 models? I'm really sure I setup all relations correctly and I already tested a lot if there is any wrong relation that might cause a recursion loop...

Maybe it's time for splitting the app into smaller services to avoid those complex relations and recursions...
