How to perform a queryset in Django with a loop for in -

i use queryset obtain user list city:

usuarios = usuario.objects.filter(municipio=muni).exclude(user_id = ide) 

so like:

[usuario: user1, usuario: user2, usuario: user3]

that need queryset obtain devices

for usuario in usuarios:     devices = gcmdevice.objects.filter(user_id=usuario.user.id) 

and last device last user(usuario):

[gcmdevice: samsung]

anybody know how can obtain devices users?

there more options. put dictionary user's id key:

for usuario in usuarios:     devices[usario.user.id] = gcmdevice.objects.filter(user_id=usuario.user.id) 

but bit demanding db, doing many queries. can obtain dcmdevice records via single query:

user_ids = usuario.objects.filter(municipio=muni).exclude(user_id=ide).values_list('user_id', flat=true) devices = gcmdevice.objects.filter(user_id__in=user_ids)
