我试过这个,但在 django 中没有更新。
def update_product(request):
a= ProductForm(instance=Product.objects.get(product_id =2))#static id
render_to_response('profiles/updateproduct.html',{'form': a},RequestContext(request))
if request.method == "POST":
form = ProductForm(request.POST, instance=a)
if form.is_valid():
j=form.save(commit=False)
j.save
confirmation_message = "product information updated successfully!"
return HttpResponse("hhhh")
else:
form = ProductForm( instance = a )
