Instantiating Mandango without a cache

[Bar Ziony]

Hey,

Is it possible to Instansiate Mandango without a cache?

What is the purpose of the cache exactly? When does it kick in?

Thanks,

Bar.

It caches the fields you query automatically: http://mandango.org/doc/mandango/query-cache.html

It's very worth using it, but if you don't want you can simply use ArrayCache, which doesn't persist anything between requests: https://github.com/mandango/mandango/blob/master/src/Mandango/Cache/ArrayCache.php

I don't understand one thing in that page:

When you use the getters for a model, each getter is going to MongoDB and getting the document over and over again? Or does Mandango getting it just one time (when you do the first getter for example, or when you do the findById()?) ?

Thanks!

Bar.

Mandango does it one time, and then it's cached and all used fields in the query are queried together. You can test an example by using a logger.

Why Mandango gets only the _id in the first time? Not that it matters a lot since it's only the first request, just to know.

[Pablo Díez]

Because it's the only required field to know which document it is.

[Bar Ziony]

Yep, but if I just did: findById, and all I get from MongoDB is the _id - isn't that redundant ?

[Pablo Díez]

The id is always returned )
