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

not error code
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.

First parameter for JsonResponse takes a dict. You are passing in json.dumps which will return a converted string corresponding to your dicts list. Use something like
JsonResponse({'data':dicts}, safe=False)
If your code's indent is not wrong, you have a logical error.In your second for loop for cat in query.news_category.all() change news_category variable, but it doesn't inserted anywhere .
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
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?

ValueError: too many values to unpack (expected 2)
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)
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
