Django : select_related with ManyToManyField

Question

I have :

class Award(models.Model) :
    name = models.CharField(max_length=100, db_index=True)

class Alias(models.Model) :
    awards = models.ManyToManyField(         


        

Answer 1

Django versions 1.4 and above have prefetch_related for this purpose.

The prefetch_related method is similar to select_related, but does not do a database join. Instead, it executes additional database queries and does the joining in Python.

Answer 2

If you're not on Django 1.4, there's also the django-batch-select library, which works basically the same way as prefetch_related.
