convert a django queryset into an array

问题

i would like convert a django queryset into an array like,

firstnames=Users.objects.values('firstnames')

to get a result that looks like

firstnames = ["Nancy", "Andrew", "Janet", "Margaret", "Steven", "Michael", "Robert", "Laura", "Anne"];

Any insights please? Regards Josh

回答1:

Use QuerySet.values_list and specify flat=True:

firstnames = Users.objects.values_list('firstnames', flat=True)
firstnames = list(firstnames)

回答2:

def get_array(Table, column):
    rows = Table.objects.values(column)
    return [row[column] for row in rows]

print get_array(Users, 'firstnames')
