Re: While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error
I wrote a python script to easily reset a django project. I hope it helps
you.
Just put it in the folder where manage.py file is and run it.
import os
import shutil
from pprint import pprint
folders = []
base_dir = os.path.dirname(os.path.realpath(__file__))
def get_directory_list():
global folders
global base_dir
for root, d_names, f_names in os.walk(base_dir):
for name in d_names:
folders.append(os.path.join(root, name))
folders = sorted(folders)
return folders
def delete_pycache():
global folders
for folder in folders:
if folder.endswith("__pycache__"):
shutil.rmtree(folder)
print("All __pycache__ files deleted.")
return None
def delete_migrations():
global folders
for folder in folders:
if folder.endswith("migrations"):
for item in os.listdir(folder):
if not item.endswith("__init__.py"):
os.remove(os.path.join(folder, item))
print("All migration files deleted.")
return None
def delete_sqlite3():
global base_dir
db_file = os.path.join(base_dir, "default.sqlite3")
if os.path.exists(db_file):
os.remove(db_file)
def main():
global folders
try:
get_directory_list()
delete_pycache()
delete_migrations()
delete_sqlite3()
print("All operations performed successfully.")
except Exception as e:
print("There was some error")
if __name__ == "__main__":
main()

Re: While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error
The problem with Jaydeep's code is the 'username' field is not getting
populated in the auth_user table. Django auth_user table by default must
have unique usernames. Username is what Django authenticates to by default.
Jaydeep was able to enter the initial user with email, firstname and
lastname once because he left 'username' field blank. The second time
failed because there is already a blank 'username' causing it to throw the
Unique Constraint error.
Also, as this code is written the 'userprofileinfo' table is not getting
populated with any data.

Re: While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error
Consider we want another attribute in user model other than what is already
available, for example height or weight. Still this code is giving error
and focus should be to solve the issue that OP is facing. I am also facing
same issue and trying to figure it out.
@Jaydeep Did you get to solve the issue somehow?
Thanks!

Re: While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error
I'm not sure what your objective is but you don't need to create another
model to store user data. User data is stored in the auth.models. It has
fields already available for what your trying to accomplish.

Re: While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error
You do not have to save the user 2 times in your form: user = user_form.save() user.save() Maybe this is also the problem... -- You received this message because you are subscribed to the Google Groups "Django users" group.

While registering the user with django form, it gives "UNIQUE constraint failed: auth_user.username" error
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

{% if registered %}
Thanks!
{% else %}
Register
{% csrf_token %}

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.
