Hi i'm having trouble with my search function, I want to get product and quantity items from DB as user inputs data in searchbar... but the problem is that im having getting no results.. any help?

views.py

def productsearch(request):
    try:
        product=request.GET.get['product']
        quantity=request.GET.get['quantity']
        product_result=Product.objects.filter(product_id__icontains=product)
        quantity_result=Product.objects.filter(quantity_onhand__icontains=quantity)
        return render_to_response('product/productlocation.html',{'product_result' : product_result,'quantity_result':quantity_result, 'product': product,'quantity':quantity})
    except:
        return render_to_response('product/productlocation.html')

You have syntax error, should be 

product=request.GET.get('product')
quantity=request.GET.get('quantity')

instead of

product=request.GET.get['product']
quantity=request.GET.get['quantity']

This is the reason why:

try:
    ...
except:
    ...

without specifying error type is very bad idea. You cannot say what error actually occured in your code.

Alsorender_to_response is deprecated and you should use render instead of it:

return render(request, 'product/productlocation.html',{'product_result' : product_result,'quantity_result':quantity_result, 'product': product,'quantity':quantity})
