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"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script> </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. -- You received this message because you are subscribed to the Google Groups "Django users" group.
