Form data not getting saved in django - django

Question

Since django User model had only few fields in it, I made a custom model and used it's ModelForm to save data to User model and the custom model. The models.py is as shown below
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
import datetime
class Post(models.Model):
Author=models.ForeignKey(User)
title=models.CharField(max_length=66)
content=models.TextField()
created_date=models.DateField(default=datetime.datetime.now())
published_date=models.DateField()
def publish(self):
self.published_date=datetime.datetime.now()
self.save()
class UserDetails(models.Model): #the custom model
uname=models.CharField(max_length=55)
first_name=models.CharField(max_length=55)
last_name=models.CharField(max_length=55)
age=models.IntegerField()
contact=models.CharField(max_length=13)
email=models.EmailField()
pword=models.CharField(max_length=55)
modelform :
class RegisterForm(ModelForm):
class Meta:
model=UserDetails
fields=['uname','pword','first_name','last_name','email','contact']
the views.py is like this
from django.shortcuts import render
from .models import UserDetails
# Create your views here.
from django.contrib.auth import authenticate,login,logout
from .forms import RegisterForm,LoginForm,PostForm
from django.contrib.auth.models import User
from django.db import IntegrityError
def register(request):
if request.method=='POST':
form=RegisterForm(request.POST)
try:
if form.is_valid():
form.save()
uname=form.cleaned_data['uname']
fname=form.cleaned_data['first_name']
pword=form.cleaned_data['pword']
email=form.cleaned_data['email']
contact=form.cleaned_data['contact']
lname=form.cleaned_data['last_name']
user=User.objects.create_user(uname,password=pword,email=email)
user.last_name=lname
user.save()
#form.save()
#stuff after registration
message="registration done! login again"
return render(request,'register.html',locals())
except IntegrityError:
message="username already exists!! try another"
else:
form=RegisterForm()
return render(request,'register.html',locals())
The problem is that even if I make a fresh entry to the RegisterForm, the 'message' I get is, username already exists!! try another. The auth.User model is getting updated but UserDetails is not. What am I doing wrong? (spare me if this is a stupid question :) )

if not User.objects.filter(username=uname,email=email).exists():
user=User.objects.create_user(uname,password=pword,email=email)
user.last_name=lname
user.save()
message="registration done! login again"
return render(request,'register.html',locals())
except IntegrityError:

else:
form=RegisterForm()
return render(request,'register.html',locals())

Answer 1

if form.is_valid():
# save a UserDetails obj (data are automatically get from the form) to db.
form.save()
# Get data from form
uname = form.cleaned_data['uname']
fname = form.cleaned_data['first_name']
pword = form.cleaned_data['pword']
email = form.cleaned_data['email']
contact = form.cleaned_data['contact']
lname = form.cleaned_data['last_name']
# Check if user already exists. If it doesn't, create it
if not User.objects.filter(username=uname, email=email).exists():
user=User.objects.create_user(uname, password=pword, email=email)
#stuff after registration
message = "registration done! login again"
return render(request,'register.html',locals())
See more on the ModelForm's save() method.
However, I noticed that the age model field is required. So, the save() will complain. You should better make it as: age = models.IntegerField(blank=True, null=True) or define a default value like this age = models.IntegerField(default=20). Although, defining a default age is awkward, better follow the blank=True null=True to allow empty ages.

Answer 2

Age was missing in model form Fields
