Storing Django queryset in session. Useful when you need to pass querysets between requests

gistfile1.py

import pickle

# Session key
key = 'my_qs'

# Pizza => model example
qs = Pizza.objects.filter(ingredient='tomato')
# Dumping data
request.session[key] = pickle.dumps(qs.query)

# Loading data
pizzas = Pizza.objects.all()[:1]
pizzas.query = pickle.loads(request.session[key])

# Using qs
for pizza in pizzas:
  print(pizza.ingredient)

Thank you. This is exactly what I needed and couldn't find for ages.

Thanks for sharing. Serializing just the query (that get pickled) in the database is a great idea. Most other implementations save the whole queryset in the session data...

Clever bit of code - thanks for sharing this - streamlines things a lot for me
