ive been searching for a while for information on how to do this. here is my situation. i have a ContactForm(form.ModelForm): and it excludes the ID field
which i want to be auto generated based on the last entry to the Contact table
but im not finding any examples on how to do this the help im lookin for is how to enter information without being visible to the user while at the same time automatically pre-fill the right id and i cant use pk cause it has a foriegn key to another table

If you define a field of a model as an AutoField
it will do this exact thing
EDIT:
If you want to define a custom auto incrementing ID you can do it like: from django.db import models
class MyModel(models.Model):
_id_counter = 0
custom_id = models.IntegerField()
@classmethod
def create(cls):
my_model = cls(custom_id=MyModel._id_counter)
MyModel._id_counter += 1
return my_model
model1 = MyModel.create()
