Re: Saving data from a form.

The error lies in this two rows:

form.save()

DataTable_id = DataTable.id

DataTable is the class, not the instance of the saved object! form.save() returns an instance of what has been saved. So your code should look like this:

my_new_datatable_instance = form.save()

DataTable_id = my_new_datatable_instance.id

That should do the trick

forms.py:
class DataTableForm(forms.ModelForm):
    class Meta:
        model = DataTable

views.py:

def datatables(request):
    if request.method == 'POST':
        form = DataTableForm(request.POST)
        if form.is_valid():
            form.save()
            DataTable_id = DataTable.id
            return render(request, 'myapp/tabspec/{{DataTable_id}}.html', {
                'DataTable_id' : DataTable.id,
                })
    else:
        form = DataTableForm()
    return render(request, 'myapp/datatables.html', {
        'form': form,
    })

When I input data on the form, and click "Confirm Selections", I get

"object DataTable has no attribute 'DataTable_id'"

Should I be using a different method to save the data from the form to the database?
