When I try to register a user using Django form, it gives me "UNIQUE
constraint failed: auth_user.username". When I tried registering the first
user, it worked, but I couldn't see that entry in my database. When I tried
registering the second user, it's giving me this error. Please, help me
through this. I have spent a considerable amount of time on this and I'm
stuck.
This is my code:
forms.py
from django import forms
from django.contrib.auth.models import User
from volunteer.models import UserProfileInfo
class UserForm(forms.ModelForm):
class Meta():
model = User
fields = ('email','first_name','last_name')
views.py
from django.shortcuts import render
from volunteer.forms import UserForm
def register(request):
registered = False
if request.method =="POST" :
user_form = UserForm(data=request.POST)
if user_form.is_valid():
user = user_form.save()
user.save()
registered = True
else:
print(user_form.errors)
else:
user_form = UserForm()
return render(request, 'volunteer/volunteer.html',
{'user_form':user_form,
'registered':registered})
models.py
from django.db import models
from django.contrib.auth.models import User
class UserProfileInfo(models.Model):
user=models.OneToOneField(User)
def __str__(self):
return self.user.first_name
return self.user.last_name
return self.user.email
urls.py
from django.conf.urls import url
from . import views
app_name = 'volunteer'
urlpatterns = [
url(r'^', views.register, name='register'),
]
admin.py
from django.contrib import admin
from volunteer.models import UserProfileInfo
# Register your models here.
admin.site.register(UserProfileInfo)
volunteer.html file which has the user form
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content = "width=device-width, initial-scale=1.0">

</head>
<body>
<div class="jumbotron">
{% if registered %}
<h1>Thanks!</h1>
{% else %}
<h1>Register</h1>
<form method="post">
{% csrf_token %}
{{ user_form.as_p }}
<input type="submit" name="" value="Register">
{% endif %}
</div>
</form>
</body>
</html>
I feel there's some problem in views.py or models.py, or volunteer.html. or
maybe something else. Please, guide me through this.
Thanks in advance.
