I have a big dictionary with more than 50 items. I am trying to return this dictionary in the form of JSON.
The code for that is:-
return HttpResponse(json.dumps(responseData, indent = 0, default=str), content_type="application/json")
There are some date fields in the dictionary and so I mentioned default=str to convert them to string.
When I print the json.dumps, I do see proper values present in the json. But when I put it in HttpResponse, I get the below error:-
too many values to unpack (expected 2)
Could somebody tell me why exactly its happening and what is the workaround?

The error is in your query (that's why I asked for the traceback):
cmsPointScore = PspstCmspointscore.objects.filter(model_id)
You should add the field name to the filter expression, for example:
cmsPointScore = PspstCmspointscore.objects.filter(model_id=model_id)

Hello I'm newbie Python user.
I study now django queryset. but
query.pyi in _BaseQuerySet's method
def values(self, *fields: Union[str, Combinable], **expressions: Any) -> ValuesQuerySet[_T, Dict[str, Any]]: ...
I want to pass a parameter to that function, but the first code runs, but the second code does not.
here is error code
valuelist = ("col1", "col2")
comment = Comment.objects.annotate(col1=F("contents"), col2=F("comment_depth")).values(valuelist)
and showed up if above code run

comment = Comment.objects.annotate(col1=F("contents"), col2=F("comment_depth")).values("col1", "col2")
What should I do to get it running normally?
The error is in the .values(…) clause: you can not pass a tuple as parameter. You use iterable unpack to unpack the values of an iterable as individual parameters. This is done by putting an asterisk (*) in front:
Comment.objects.annotate(
col1=F('contents'),
col2=F('comment_depth')
).values(*valuelist)
That being said, often it is not a good idea to work with .values(…) [Django-doc] since it "erodes" the model layer.

The model of 'Currency' is:
class Currency(models.Model):
currency_name = models.CharField(max_length=100)
currency_value_in_dollars = models.FloatField()
currency_value_in_dollars_date = models.DateTimeField()
def __str__(self):
return self.currency_name
Why can't I filter by 'currency_value_in_dollars_date'? check if the currency value has been updated within the last hour.
You can not simply uses a list of two values to filter. If you for example want to retrieve all elements in between you can work with a __range lookup [Django-doc]:
from django.utils.timezone import now
current_time = now()
up_to_date_currency = Currency.objects.filter(
currency_value_in_dollars_date__range=(
current_time-timedelta(hours=1),
current_time
)
).order_by('-currency_value_in_dollars_date')[:len(coins_ids)]
This will thus retrieve all Currency objects between an hour ago and now.
If by
check if the currency value has been updated within the last hour
you mean you want to filter all rows up to 1 hour ago, then replace
currency_value_in_dollars_date=
[datetime.now(), timedelta(hours=1)]
with (notice __gte)
currency_value_in_dollars_date__gte=datetime.now() - timedelta(hours=1)
If you want to filter by array, then you'd have to either use JSONField to match value, or use __in to execute SQL in. Otherwise, you can't filter by array, so what you did is basically invalid.
Depending on your settings, you should probably use timezone.now() from django instead of datetime.
I am trying to filter my product list with price less than filter but getting error. I guess the error is I am unable to pass parameters correctly.
any help would be appreciated.
if you require anymore details, please ask.
Note: it does not works even if I pass the query on filter body static.
thanks in advance.
my method:
def getfilter(request, format=None):
kwargs = {
'{0}__{1}'.format('price', 'lt'): Decimal('1000.00'),
# '{0}__{1}'.format('name', 'endswith'): 'Z'
}
products = Product.objects.all().filter(**kwargs)
serializer = ProductSerializer1(products, many=True)
return Response(serializer.data)

It seems like the conversion from Decimal to string failed:
'{0}__{1}'.format('price', 'lt'): Decimal('1000.00'),
and corresponding SQL:
< %(0)s
I guess one of this possible troubles:
your model field price type is incorrect for this conversion
your decimal value have two zero numbers after decimal point - try to
remove the last one

Destroying test database for alias 'default'...
Any help would be appreciated, thank you!
The error likely happens because event_date ends up with the value False, which happens because there was no value for 'event_date' in request.GET.
According to the docs of Client.get(), you have to pass a dict with the GET/POST parameters of the request, not using kwargs.
Try by changing this line (which is using kwargs):
request = c.get('/profile/1/check_availability/', event_date='1999-12-20')
to this (now using a dict as the second parameter)
request = c.get('/profile/1/check_availability/', {'event_date': '1999-12-20'})
I am creating the dynamic queryset using Q
while i am printing
build_query[:-1]
i am getting output
Q(owner_id=1)|Q(assigned_to=1)
but when using this in to
consultants = Consultant.objects.filter(*build_query[:-1])
getting an error too many values to unpack
i tried it with ** and without * still its not working.
when i check the type of
print type(build_query[:-1])
i am getting string type. Is the a main cause?

Did u try:

args should be a list
