@iammiracle Why dont you implement an email verification method? first when a user sign up with username, email and password they are not automatically logged to your site unless the email is verified, django already have this.
I'm beginner in django. I had learned from some tutorials and combined the explanations to my own app. But I'm still clueless about the way to calculate values from my form and save it. it's simply like a+b+c = d whereas a, b, c and d are stated in my models.py. a, b, c and d are decimalField .
