Override django's RelatedManager for model

Question

How i can override manager for relations? For example:

user.entry_set # django.db.models.fields.related.RelatedManager

But i need for my own manager. I try this code, but this does not work:

class EntryManager(models.Manager):
    use_for_related_fields = True

Thanks.

You task requires rather hacky code which will be very hard to maintain and understand (if it's even possible).

What about this?

class EntryManager(models.Manager):
    def by_user(self, user):
        # do anything you want

# usage
Entry.objects.by_user(user=user)
