to Django users

I am working on a Role Based Access Control system on django.where at the signup/register people will be designated to a 'department' and will be assigned a 'role' Hence I created a custom user model

models.py

from django.db import models

from django.contrib.auth.models import User

from django.db.models.signals import post_save

from django.dispatch import receiver

class Profile(models.Model):

DEPARTMENT_CHOICES = (

('Production', 'Production'),

('Marketing', 'Marketing'),

('IT', 'IT'),

('HR', 'HR'),

('Accounts', 'Accounts'),

)

ROLE_CHOICES = (

('Manager', 'Manager'),

('Team Lead', 'Team Lead'),

('Member', 'Member'),

)

user = models.OneToOneField(

User,)

department = models.CharField(

max_length=50, choices=DEPARTMENT_CHOICES, null=True)

role = models.CharField(max_length=50, choices=ROLE_CHOICES, null=True)

def __unicode__(self):

return unicode(self.user.first_name + ' ' + self.user.last_name)

def __str__(self):

return self.user.first_name + ' ' + self.user.last_name

def create_profile(sender, **kwargs):

if kwargs['created']:

user_profile = Profile.objects.create(user=kwargs['instance'])

pass

post_save.connect(create_profile, sender=User)

Then i created a form like

forms.py

from django import forms

from django.contrib.auth.forms import UserCreationForm

from django.contrib.auth.models import User

from .models import Profile

class SignUpForm(UserCreationForm):

DEPARTMENT_CHOICES = (

('Production', 'Production'),

('Marketing', 'Marketing'),

('IT', 'IT'),

('HR', 'HR'),

('Accounts', 'Accounts'),

)

ROLE_CHOICES = (

('Manager', 'Manager'),

('Team Lead', 'Team Lead'),

('Member', 'Member'),

)

first_name = forms.CharField(

max_length=30, required=True, help_text='Optional.')

last_name = forms.CharField(

max_length=30, required=True, help_text='Optional.')

email = forms.EmailField(

max_length=254, required=False)

department = forms.ChoiceField(choices=DEPARTMENT_CHOICES, )

role = forms.ChoiceField(choices=ROLE_CHOICES, )

class Meta:

model = User

fields = ('first_name', 'last_name', 'username',

'email', 'password1', 'password2', 'department', 'role')

The my views

from django.shortcuts import render, redirect, render_to_response

from django.contrib.auth.decorators import login_required

from django.contrib.auth import login, authenticate

from .forms import SignUpForm

from .models import Profile

from django.shortcuts import get_object_or_404

from django.http import Http404

from django.contrib.auth.models import User

from django.template import RequestContext

def register(request):

if request.user.is_authenticated:

if request.user.is_superuser or request.user.role == 'Manager':

if request.method == 'POST':

form = SignUpForm(request.POST)

if form.is_valid():

user = form.save()

userprofile = Profile.objects.update(

user=user, department=form.cleaned_data['department'])

userprofile = Profile.objects.update(

user=user, role=form.cleaned_data['role'])

else:

form = SignUpForm()

c = {

'form': form,

}

return render(request, 'registration/register.html', c)

else:

raise Http404

else:

raise Http404

my register.html

{% extends 'layouts/base.html' %} {% load widget_tweaks %}{% block additionalbottom %}

var allParas = document.getElementsByTagName('div');

//filter by class name if desired...

for (var i = 0; i < allParas.length; i++) {

if (allParas[i].getElementsByTagName('*').length == 0) {

allParas[i].style.display = 'none';

}

</script>

{% endblock %} {% block content %}

<h2>User Registration</h2>

{% csrf_token %}

{% endblock %} {% for field in form %}

{% if field.name == "first_name" or field.name == "last_name" %} {% render_field field class="form-control" placeholder=field.label.capitalize %} {% endif %}

</div>

{% if field.name == "username" or field.name == "email" %} {% render_field field class="form-control" placeholder=field.label.capitalize %} {% endif %}

</div>

{% if field.name == "department" or field.name == "role" %} {% render_field field class="form-control" placeholder=field.label.capitalize %} {% endif %}

</div>

{% if field.name == "password1" %} {% render_field field class="form-control" placeholder=field.label.capitalize %} {% endif %}

</div>

{% if field.name == "password2" %} {% render_field field class="form-control" placeholder=field.label.capitalize %} {% endif %}

</div>

{% endfor %}

</div>

<button type="submit">Register</button>

</div>

</form>

{% if form.errors %} {% for field in form %} {% for error in field.errors %}

<strong>{{ error|escape }}</strong>

</div>

{% endfor %} {% endfor %} {% for error in form.non_field_errors %}

<strong>{{ error|escape }}</strong>

</div>

{% endfor %} {% endif %}

</div>

now when ever i try to submit my form it says

> IntegrityError at /register/

> column user_id is not unique

i tried so many solutions from google and SO nothing seems to solve the problem can anyone tell me how to fix it or why it cannot be done if it cannot be done what is the work around

You are only posting a little part of the error. It would be a lot
easier to help you if you posted the whole error
