I am doing a CRUD of Products.I am struggling to view the data that I am trying to insert. below is the models,serializer(since I am suppsoed to use serializers instead of forms),functions and htmls
class Products(models.Model):
categories = models.CharField(max_length=15)
sub_categories = models.CharField(max_length=15)
color = models.CharField(max_length=15)
size = models.CharField(max_length=15)
# image = models.ImageField(upload_to = 'media/',width_field=None,height_field=None,null=True)
title = models.CharField(max_length=50)
price = models.CharField(max_length=10)
sku_number = models.CharField(max_length=10)
product_details = models.CharField(max_length=300)
quantity = models.IntegerField(default=0)
isactive = models.BooleanField(default=True)
class POLLSerializer(serializers.ModelSerializer):
class Meta:
model = Products
fields = "__all__"
def show(request):
showall = Products.objects.all()
print(showall)
serializer = POLLSerializer(showall,many=True)
print(serializer.data)
return render(request,'polls/product_list.html',{"data":serializer.data})
def insert(request):
if request.POST == "POST":
print('POST',id)
insert_clothes = {}
insert_clothes['categories']=request.POST.get('categories')
insert_clothes['sub_categories']=request.POST.get('sub_categories')
insert_clothes['color']=request.POST.get('color')
insert_clothes['size']=request.POST.get('size')
# insert_clothes['image']=request.POST.get('image')
insert_clothes['title']=request.POST.get('title')
insert_clothes['price']=request.POST.get('price')
insert_clothes['sku_number']=request.POST.get('sku_number')
insert_clothes['product_details']=request.POST.get('product_details')
insert_clothes['quantity']=request.POST.get('quantity')
form = POLLSerializer(data = insert_clothes)
if form.is_valid():
form.save()
# print('data',form.data)
print(form.errors)
messages.success(request,'Record Updated successfully :)!!!!')
return redirect('polls:show')
else:
print(form.errors)
else:
print('GET',id)
insert_clothes = Products.objects.all()
form = POLLSerializer(data = insert_clothes)
if form.is_valid():
print(form.errrors)
return render(request,'polls/product_insert.html')
below is insert html code

<a href="/Delete/{{result.id}}/" onclick="return confirm('Are You Sure you want to delete?')">

</button>
</a>
</td>
</tr>
</tbody>
{% endfor %}
the namings of functions and names of the input and of models appear to be correct so where am I going wrong?
CodePudding user response：
I see that you are constructing dict for your serializer. I'm pretty sure you should use Product instance intead.
Build Product instance from request data and then pass it to serilaizer
product = Product(
categories=request.POST.get('categories'),
... # etc etc
)
form = POLLSerializer(product)
or you can even try:
form = POLLSerializer(request.data)
