I have the following code:

    bannerVar = models.CharField(max_length = 50)

    def __unicode__(self):
        return u'%s %s %s %s' % (self.datFile, self.structFile, self.bannerVar, self.stubVar)

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()
            return redirect('myapp/tabspec.html')
    else:
        form = DataTableForm()
    return render(request, 'myapp/datatables.html', {
        'form': form,
    })

def tabspec(request):
    try:
        datFile = DataTable.datFile
        context = Context({
            'datFile': datFile,
        })
    except DataTable.DoesNotExist:
        raise Http404
    return HttpResponse(template.render(context))

The DataTable view shows, as a form; I enter the values for the ields, when I click the button, I get the error "type object 'DataTable' has no attribute 'datFile'".  I thought maybe I should be referring to DataTableForm.datFile, but this gave the same error.
I am confused, could any one tell me where I am going wrong?

datFile (terrible name, by the way) is a field on a DataTable *instance*. You need to pass an ID value to the tabspec view (via the URL) from your form view, then use DataTable.objects.get(pk=id) in that tabspec view.
