Since i created 2 categories in the admin panel like this:
but when i want to post this json it gives my this error:
[
{
"category": [
"Incorrect type. Expected pk value, received str."
]
},
{
"category": [
"Incorrect type. Expected pk value, received str."
]
}
]
json:
[
{
"image": "https://a ",
"description": "J t",
"price": "USD 8.70",
"buy": "https:// 6d7",
"category": "foods"
},
{
"image": "https:// ",
"description": " elf",
"price": " 65",
"buy": "https://s.c D",
"category": "foods"
}
]
What should i write in "category": to create a post that belongs to a specific category like foods?
models:
class category(models.Model):
name=models.CharField(max_length=255, db_index=True)
def __str__(self):
return self.name
class product(models.Model):
category = models.ForeignKey(category, related_name='products',on_delete=models.CASCADE)
image=models.CharField(max_length=500)
description=models.CharField(max_length=500)
price=models.CharField(max_length=50)
buy=models.CharField(max_length=100)
views:
class productviewset(viewsets.ModelViewSet):
queryset=product.objects.all()
serializer_class = productSerializer
def create(self, request):
serialized = productSerializer(data=request.data, many=True)
if serialized.is_valid():
serialized.save()
return Response(serialized.data, status=status.HTTP_201_CREATED)
return Response(serialized._errors, status=status.HTTP_400_BAD_REQUEST)
@action (detail=False , methods=['post'])
def delete(self,request):
product.objects.all().delete()
return Response('success')
def home(request):
return render(request,'home.html',{'p':category.objects.all()})
def foods(request):
return render(request,'foods.html',{'p':category.objects.all()})
>Solution :
you need to send pk >> primiary key or id of Category object, for your example, pk 1 is home, and pk 2 is foods
