[Fixed]-ModelForm returning field is required, not saving to sqliteDB

You don’t need to have the driver_number field in the TimeClockIN model (it already exists in the driver field). You can create a normal django form where you retrieve the driver_number. Afterwards, try to get the driver from the db and if it exists, create a new TimeClockIN instance with the coresponding data and save it. This assumes that each driver_number is unique among Drivers.

If you later need to get the driver_number from the TimeClockIN model, you just follow the driver foreign key and get it from there.

Model:

class TimeClockIN(models.Model):
    timestamp = models.DateTimeField()
    driver = models.ForeignKey(Driver, blank=True)

Form:

class ClockInForm(forms.Form):
    driver_number = forms.IntegerField(required=True, max_length=8)

View:

def clock_in_view(request):
    form = forms.ClockInForm()

    if request.method == 'POST':
        form = forms.ClockInForm(request.POST)
        if form.is_valid(): 
            try: 
                driver = Driver.objects.get(driver_number=form.cleaned_data['driver_number'])
                time_in_instance = TimeClockIN()
                time_in_instance.timestamp = timezone.now()
                time_in_instance.driver = driver
                time_in_instance.save()
                messages.add_message(request, messages.SUCCESS,
                                    "Clocked IN")
                return HttpResponseRedirect(reverse('clockin'))
            except Driver.DoesNotExist:
                form = forms.ClockInForm()
    return render(request, 'clockinform.html', {'form': form})
