Django ORM cache

Question

I have several models with one-to-many relationships. In my management commands I need to iterate over all entities multiple times. I.e. I have multiple loops like this:

for childEntity in dbObj.childEntities.all():
    ....

Does Django use session cache for dbObj.childEntities.all()? Or I need to cache results somehow?

Answer 1

No, not by default. You can enable it by using prefetch_related.
