While registering this error is occurring. I'm using postgresql as DBMS .
Request Method: POST

You are using request.POST but you are not passing any form to it after.
You should explicitly pass the form in the different requests so that django will know what to handle.

django returning 'AnonymousUser' object has no attribute '_meta' error

I am developing a feature, when a user registers it automatically logs the user in
but i get 'AnonymousUser' object has no attribute '_meta' error.
but when i use the same code to login the user it works fine.
my forms.py:
from django.contrib.auth.forms import UserCreationForm
from django import forms
from django.core.exceptions import ObjectDoesNotExist
from django.contrib.auth.models import User
from .models import *
class RegisterForm(forms.Form):
fname = forms.CharField(error_messages=(), widget=forms.TextInput(attrs={"class":"fname entry", "placeholder":"First Name"}), required=True)
lname = forms.CharField(error_messages=(), widget=forms.TextInput(attrs={"class":"lname entry", "placeholder":"Last Name"}), required=True)
phone = forms.CharField(error_messages=(), widget=forms.TextInput(attrs={"class":"phone entry", "placeholder":"Phone Number"}), required=True)
password = forms.CharField(widget=forms.PasswordInput(attrs={"class":"password entry", "placeholder":"Password", "autocomplete":"off"}), required=True)
password2 = forms.CharField(widget=forms.PasswordInput(attrs={"class":"password entry", "placeholder":"Confirm Password", "autocomplete":"off"}), required=True)
def clean(self, *args, **kwargs):
fname = self.cleaned_data.get("fname")
lname = self.cleaned_data.get("lname")
phone = self.cleaned_data.get("phone")
password = self.cleaned_data.get("password")
password2 = self.cleaned_data.get("password2")
if phone and password and fname and lname and password2:
try:
user = User.objects.get(phone=PhoneNumber.objects.get(number=phone))
if user:
raise forms.ValidationError("user exists login instead")
except ObjectDoesNotExist:
pass
if password!=password2:
raise forms.ValidationError("passwords didn't match")
else:
if len(password)<8:
raise forms.ValidationError("short password! password should be longer than 8")
in my forms i have a registration form which does not inherit from django's user creation form.
my views.py:
def registerView(request):
if request.method == "POST":
form = RegisterForm(request.POST)
if form.is_valid():
fname = form.cleaned_data.get("fname")
lname = form.cleaned_data.get("lname")
username = generate_username(fname, lname)
phone = form.cleaned_data.get("phone")
u = User.objects.create_user(email="", first_name=fname, last_name=lname, username=username, is_active=False)
u.set_password(form.cleaned_data.get("password"))
u.save()
p = PhoneNumber(user=u, number=phone)
p.save()
phone = PhoneNumber.objects.get(number=phone)
u = User.objects.get(phone=phone)
userLogin = authenticate(username=username, password=u.password)
login(request, userLogin)
return redirect('home')
else:
form = RegisterForm()
return render(request, 'main/register.html', {'form':form})
my loginView:
def loginView(request):
if request.method == "POST":
form = LoginForm(request.POST)
if form.is_valid():
phone = PhoneNumber.objects.get(number=form.cleaned_data.get('phone'))
u = User.objects.get(phone=phone)
user = authenticate(username=u.username, password=form.cleaned_data.get('password'))
login(request, user, backend='django.contrib.auth.backends.ModelBackend')
print('success')
return redirect('home')
else:
form = LoginForm()
return render(request, 'main/login.html', {'form':form})
i have imported everything i need. the same code works with the loginView function but it doesn't work on registerView
What should i do to fix this?

You have this line in your view:
userLogin = authenticate(username=username, password=u.password)
The point to be noted here is that u is an instance of the user model and u.password will give the hashed password while authenticate expects it to be a raw password and hence returns None. In fact you don't even need to use authenticate while registering as you already have the user instance:
def registerView(request):
if request.method == "POST":
form = RegisterForm(request.POST)
if form.is_valid():
fname = form.cleaned_data.get("fname")
lname = form.cleaned_data.get("lname")
username = generate_username(fname, lname)
phone = form.cleaned_data.get("phone")
# removed `is_active=False` as per comment by #Nahu Gere
user = User.objects.create_user(email="", first_name=fname, last_name=lname, username=username) # better variable name
user.set_password(form.cleaned_data.get("password"))
user.save()
phone = PhoneNumber(user=user, number=phone)
phone.save()
login(request, user) # Directly use saved user instance
return redirect('home')
else:
form = RegisterForm()
return render(request, 'main/register.html', {'form':form})

I got this error because In my register view, I had this code:
user.is_active = False
user.save()
then I had so the user got logged in automatically after registering an account.
user = authenticate(username=user.username, password=raw_password)
login(request, user)
I solved it by commenting out the auto login
# user = authenticate(username=user.username, password=raw_password)
# login(request, user)

Django won't change url on redirect

Upon registration I check the user_type and move the user to one of three web pages.
It is showing the correct page layout but the url stays the same as the registration page.
EG: url says "http://127.0.0.1:8000/users/register/"
Page shows: "user type 1 information"
I thought using redirect should change the url but it doesn't seem to be working.
views.py:
def register(request):
if request.method == 'POST':
form = RegisterForm(data=request.POST)
if form.is_valid():
# profile = form.save(commit=False)
# profile.user = request.user
# profile.save()
user = form.save()
profile = user.userprofile
user_group = form.cleaned_data.get('user_type')
profile.user_type = user_group
profile.save()
# form.save()
username = form.cleaned_data.get('username')
password = form.cleaned_data.get('password1')
user_group = form.cleaned_data.get('user_type')
user = authenticate(username = username, password = password)
login(request, user)
print(user_group)
print(type(user_group))
if user_group == '1':
return HttpResponseRedirect("/users/business/")
# return
# HttpResponseRedirect('http://127.0.0.1:8000/users/business/')
# return HttpResponseRedirect(reverse('users:business'))
# return redirect(request, 'users/business.html')
elif user_group == '2':
return redirect(request, 'users/student.html')
elif user_group == '3':
return redirect(request, 'users/tourist.html')
# else:
# return redirect('main:index')
else:
print(RegisterForm.errors)
else:
form = RegisterForm()
def business_view(request):
# return redirect(request, 'users/business.html')
# return HttpResponseRedirect('users/business.html')
# return redirect('/users/business/')
return redirect('users/business')
def student_view(request):
return redirect(request, 'users/student.html')
def tourist_view(request):
return redirect(request, 'users/tourist.html')
urls.py
urlpatterns = [
# Login page
#url(r'^login/$', login, {'template_name': 'users/login.html'},
name='login'),
url(r'^login/$', login, {'template_name': 'users/login.html'},
name='login'),
#url(r'^login/$', views.log_in, name='login'),
# Register page
url(r'^register/$', views.register, name='register'),
# Business page
#url(r'^business/$', views.business_view, name='business'),
url(r'^$',views.business_view),
# Student page
url(r'^student/$', views.student_view, name='student'),
# Tourist page
url(r'^tourist/$', views.tourist_view, name = 'tourist'),
]
Thanks for any help.

Use urlname only in redirect argument, i.e. to redirect on student page use return redirect('student') (name defined while defining urls). Eg.
if user_group == '2':
return redirect('student')
Also in your views where you want to show html page, use render instead. Eg.
from django.shorcuts import render
def student_view(request):
return render(request, 'users/student.html')

Django request.user becomes anonymous after redirect

In my Django app I create a User from django.contrib.auth.models, and I am using request.user in multiple view functions without a problem. In one of my view functions I change the user password, save the user, and redirect the client to another view function. Once I try to get the user from the request in that function, the user is Anonymous. After using User.set_password() or redirecting, does it take the user out of the session ?

Yes. See the documentation about session invalidation on password change. To fix it, see this bit in particular:
The default password change views included with Django, PasswordChangeView and the user_change_password view in the django.contrib.auth admin, update the session with the new password hash so that a user changing their own password won't log themselves out. If you have a custom password change view and wish to have similar behavior, use the update_session_auth_hash() function.

i want to make def full_profile and def edit_profile.
How can i get logged in user consul_id??
please help me

Not sure that I understand you problem well.. Take a look at recommended way of extending User model:
https://docs.djangoproject.com/en/dev/topics/auth/customizing/#extending-the-existing-user-model
from django.contrib.auth.models import User
class Employee(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
department = models.CharField(max_length=100)
Then you can do:
u = User.objects.get(username='fsmith')
freds_department = u.employee.department
In your case it would be:
class Consultant(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
*your fields here*
Now you can use standard authentication forms and methods
You always can obtain consultant data as:
request.user.consultant
