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?

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

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.
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)

Version: 1.2.32
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'm trying to override the method save() of my model:
class Article(models.Model):
number = models.PositiveIntegerField(editable=False)
def save(self, *args, **kwargs):
if not self.pk: #means: if objects wasn't saved before
self.number = Article.objects.count() +1 #number is 1-based
super(Article, self).save(*args, **kwargs)
Now I tried to add a new article from the admin page. The error I get:
self.number = Article.objects.count() +1
NameError: name 'self' is not defined
What am I doing wrong?
Some optional information:
number is some kind of ID, to order the objects in my way but these IDs shouldn't be changed manually
number is not allowed to be empty or blank, so I have to set a value before saving the first time (that's what I'm trying with that code snippet)
When an object is saved, the default number should be equal to the number of all objects (after saving), in 1-based counting
to change the order of the objects admin actions will be used
