hello
I'm trying to remove some duplicate data on my db
def duplicates():
plans_rebalances=PlanRebalance.objects.filter(rebalance_date="2016-04-29").order_by('id')
for rebalance in plans_rebalances:
repeated = PlanRebalance.objects.filter(rebalance_date="2016-04-29", real=False, plan=rebalance.plan).annotate(
Count('plan')).filter(plan__count__gt=1)
while repeated.plan__count > 1:
print(repeated)
first, rest = repeated[0], repeated[1:]
rest.remove()
but I get this error
'QuerySet' object has no attribute 'plan__count'
i think it is because
repeated has the entire queryset
maybe you should do a loop for that like
for plan_rebalance in repeated:
^
i'll test it
https://docs.djangoproject.com/es/1.10/ref/models/querysets/#select-related i think this will also help you with performance
hello is here someone ?
Okay so when I try to run python -Wall manage.py test to see what warnings I need to deal with to upgrade, I get thousands of ImportWarnings and can't read anything else. Is there a way to log everything or filter out those specific warnings?
Using a package as a library vs using it as an app -- what's the difference? Django-organizations says it can be used as a library -- I think this means that I need to manually bring in its various base and abstract base classes into my own project's models. Am I understanding that right?
