You can define a value for the model's field by using the commit=False "trick".
myform.save(commit=False) returns an instance of the model which hasn't yet been saved to the database. So you can manually set the value for any additional fields and then call save on the object to finally write it to the db. Please see the official docs[1] for futher reference. In the future, try to pick a subject for your e-mail that explicitly states the problem. Something like "hi" will get ignored most of the time!
