    copied!<p>I am having problem saving additional information about each user automatically when a new user signs-up. I have created a profile for User model extension to save additional data about my users. However, when the signal handler gets called at post_save, the data stored in the request is not passed to the signal_handler. </p> <p>The following is the profile that I have created.</p> <pre><code>class StudentProfile(models.Model): user = models.ForeignKey(User, unique=True) # Other information about the Student city = models.CharField(max_length=25) country = models.CharField(max_length=25) student_age = models.IntegerField(max_length=3) </code></pre> <p>In my signup view I call form.save() function in which the User object gets created and a new row is added in the data base. </p> <pre><code>def save(self, new_data): u = User.objects.create_user( new_data['username'], new_data['email'], new_data['password']) return u </code></pre> <p>After that, the post_save signal is called and the signal handler tries to create a new profile:</p> <pre><code>def create_student_profile(sender, instance, created, **kwargs): if created: StudentProfile.objects.create(user=instance) post_save.connect(create_student_profile, sender=User) </code></pre> <p>At this point, I get the following error in the broswer:</p> <p><strong>IntegrityError at /signup/ (1048, "Column 'student_age' cannot be null")</strong></p> <p>I looked at the call stack and found that the SQL query that is being executed has None value for Student_age and nothing for country and city.</p> <p>sql u'INSERT INTO <code>student_studentprofile</code> (<code>user_id</code>, <code>city</code>, <code>country</code>, <code>student_age</code>) VALUES (17, , , None)'</p> <p>How can I pass the request parameters such as student_age, country and city to this signal handler? Do I have to manually save this information? </p> <p>I have thoroughly searched for the answer of this question on stackOverflow and Google and I have come rather empty handed.</p> <p>Thanks for your help.</p>
