Question

I have a model that looks like the following:

class Loves(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    user_name = models.CharField(max_length=200)

Data in the model looks like:

poll choice_text user

1 a mike

1 b mike

1 c james

2 a james

2 b melody

1 d mike

How do I output a list that looks like:

user tuples
mike (1,a),(1,b),(1,d)
james (1,c), (2,a)
melody (2,b)

Thanks.

Answer 1

collection={} 
for l in Loves.objects.all():
    if l.user_name in collection:
        collection[l.user_name].append((l.poll,l.choice_text))
    else:
        collection[l.user_name]=[(l.poll,l.choice_text)]
# and to turn it into a list just do
results_list=list(collection)
