Add additional data when django form is saved - django

Question

I am looking for some help in my first django app and I am new to programming. I have the below scenario:
Models:
class save_table(models.Model):
name=models.CharField(max_length=100)
UniqueuserID = models.CharField(max_length=7)
UserLocation = models.CharField(max_length=100)
UserLead = models.CharField(max_length=50)
def __str__(Self):
return self.UniqueuserID
class data_table(models.Model):
UniqueuserID = models.CharField(max_length=7)
name=models.CharField(max_length=100)
UserLocation = models.CharField(max_length=100)
UserLead = models.CharField(max_length=50)
Form:
class save_table_form(forms.ModelForm):
class Meta:
model = save_table
fields = ('UniqueuserID')
def __init__(self,*args,**kwargs):
super(save_table_form,self).__init__(*args,**kwargs)
Every user ID that the user will add to the form will have a respective data entry int he second model and I want to save that additional data along with the form. However I did not use a foreign key because I do not want the saved model data in the save_table to change based on the changes in the data_table. Can I add the additional data to the form before saving the form.
if form.is_valid():
form.save()
Please help..

Yes you can add aditional data when saving the form!
overwrite the saving methoud in class save_table_form:
like this :
class save_table_form(forms.ModelForm):
def save(self, commit=True):
user_id = self.cleaned_data['id']
user_photo = self.cleaned_data['photo']
user_password = self.cleaned_data['password1']
user = SysUser.objects.get(pk=user_id)
user.username = self.cleaned_data['username']
if user_password:
user.set_password(self.cleaned_data['password1'])
user.first_name = self.cleaned_data['first_name']
user.mobile = self.cleaned_data['mobile']
user.office_id = self.cleaned_data['office_id']
if user_photo:
user.image = user_photo
user.save()
user.user_permissions.clear()
user.user_permissions.add(*self.cleaned_data['user_permissions'])
print('data is saving')
return user
