Hey, no problem! My apologies for missing out on this thread for a
while. I hope you got it figured out!
Anyways, I'm thinking that if you're actually basing this validation
(done in your clean method), you may want to use a ForeignKey Field.
You can define a custom queryset to filter through the results if you
only want certain teachers to be available.
Otherwise, you could put a method along these lines in your current Form class.
import Teacher
from (some django forms module) import ValidationError
class MyForm(Form):
...
def clean__teacher(self):
teacher = self.cleaned_data['teacher'] # Value of the chosen teacher
if Teacher.objects.filter(name=teacher).exists():
return True
else
raise ValidationError("You have chosen an invalid teacher")
Hopefully that helps a bit. If not, let me know and I'll try to help
some more :)
