问题
I am new to django, I created my custom user(auth_user) model. I need to create student registration form using custom user model according to my custom object
I have two models Title, User like this:
from django.db import models
#from django.contrib.auth.models import User
from django.contrib.auth import get_user_model
from django.db.models.signals import post_save
from django.contrib.auth.models import AbstractUser
class Title(models.Model):
value = models.CharField(max_length=100, null=True, blank=True)
def __str__(self):
return self.value
class Meta:
db_table = 'title'
class User(AbstractUser):
title = models.ForeignKey(Title, on_delete=models.CASCADE, null=True, blank=True)
class Meta:
db_table = 'user'
settings.py:
AUTH_USER_MODEL = 'student.User'
Here i have ForeignKey title field and User default fields first_name, last_name, email,password
My forms.py:
from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
from django.core import validators
from student.models import User
from student.models import Title
class StudentRegistrationForm(forms.Form):
filenumber = forms.CharField(label='Filenumber', max_length=45)
class StudentNewRegistrationForm(forms.ModelForm):
title = forms.CharField(required=True)
username = forms.CharField(required=True)
first_name = forms.CharField(required=True)
last_name = forms.CharField(required=True)
email = forms.EmailField(required=True)
password1 = forms.CharField(required=True)
password2 = forms.CharField(required=True)
def __init__(self, *args, **kwargs):
super(StudentNewRegistrationForm, self).__init__(*args, **kwargs)
self.fields['title'] = forms.ModelChoiceField(queryset=Title.objects.all(), empty_label='Choose a title',required=False)
class Meta:
model = User
fields = ['title','username', 'first_name', 'last_name','email' 'password1', 'password2']
def save(self, commit=True):
user = super(StudentNewRegistrationForm, self).save(commit=False)
user.username = self.cleaned_data['username']
user.first_name = self.cleaned_data['first_name']
user.last_name = self.cleaned_data['last_name']
user.email = self.cleaned_data['email']
user.title = self.cleaned_data['title']
user.password1 = user.set_password(self.cleaned_data['password1'])
user.password2 = user.set_password(self.cleaned_data['password2'])
if commit:
user.save()
return user
Here i have api response like below:
{"candidate":{"firstname":"Testuser","lastname":"test","salutation":10000,"email":"testing@gmail.com","username":"test"}}

jsonresult = studentapires['studentres']['candidate']
user = User()
if jsonresult['salutation'] == 100000000:

You need to change User model inside your views.py file and in any other files where you are using User class. To new model. For this try to add following import:
from django.contrib.auth import get_user_model
User = get_user_model()
Instead of
from django.contrib.auth.models import User
