I have surround book.save with a try...catch...; the exception is:
You must not use 8-bit bytestrings unless you use a text_factory that
can interpret 8-bit bytestrings (like text_factory = str). It is
highly recommended that you instead just switch your application to
Unicode strings.
Without the try...catch, here is the traceback:

All right.
class Book(models.Model):
code = models.PositiveIntegerField(primary_key=True)
title =
models.CharField(max_length=60,blank=False,null=False)
book = Book()
book.code = 1
book.title = 'Verità'
book.save()
the code is really simple
