Re: Issue with CRUD Operation

To clear your form after submit, just re-assign an empty form object after the form.save(). See below

def soapprod_form (request, id=0):

    if request.method == "GET":

        if id == 0:

            form = SoapprodForm()

        else:

            soapprod = Soapprod.objects.get(pk=id)

            form = SoapprodForm (instance=soapprod)

        return render(request, "soapprod_form.html", {'form': form})

    else:

        if id == 0:

            form = SoapprodForm(request.POST)

        else:

            soapprod = Soapprod.objects.get(pk=id)

            form = SoapprodForm(request.POST,instance= soapprod)

        if form.is_valid():

            form.save()

            form = SoapprodForm()

        return render(request, "soapprod_form.html", {'form': form})

Hi,

Please also attach the code of your list template where the delete is been executed.

Hello,

I performed a CRUD operation and every thing is working well except two things

1. my insert form does not clear the text boxes after saving a record

2. my delete operation renders an error page after deleting a record with a message ''DoesNotExist at /delete/3/" or "AttributeError at /delete/6/" 

example of the error messages are  shown below. i also attached view.py, model.py and template file

DoesNotExist at /delete/3/
