I want username field automatically filled with this:

You can use hooks to achieve this.

It would be something like this (not tested):

from django.db import models

  class User(models.Model):
    email = model.EmailField()
    username = models.CharField(max_length=80)

    def save(self):
      if not self.id:
           self.username = ''
           super(User, self).save()
      self.username = "%i%s" % (self.id, self.email)
      super(User, self).save()
