MyUser login in Django 1.5. Again - django

I try to login users from MyUser model in django 1.5. I use e-mail as login, see model:
class MyUser(AbstractBaseUser):
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
db_index=True,
)
last_name=models.CharField(max_length=30)
first_name=models.CharField(max_length=30)
second_name=models.CharField(max_length=30, blank=True)
post=models.CharField(max_length=30, blank=True)
objects = MyUserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['last_name','first_name','second_name','post',]
def get_full_name(self):
return self.email
def get_short_name(self):
return self.email
def __unicode__(self):
return self.email
def has_perm(self, perm, obj=None):
return True
def has_module_perms(self, app_label):
return True
#property
def is_staff(self):
return self.is_admin
And I added LoginForm:
class LoginForm(forms.Form):
username = forms.CharField(max_length=100)
password =forms.CharField(widget=forms.PasswordInput(render_value=False),max_length=100)
view:
def login_view(request):
if request.method == 'POST':
username = request.POST['email']
password = request.POST['password']
user = authenticate(username=username, password=password)
if user is not None and user.is_active:
login(request, user)
return HttpResponseRedirect("/home.html")# Redirect to a success page.
return HttpResponseRedirect("/account/invalid/")# Return a 'disabled account' error message
form=LoginForm()
return render(request, 'enter.html', {'login_form': LoginForm})
template:
{% if form.errors %}
<p>Something is wrong</p>
{% endif %}
<form action="" method="post">
{% csrf_token %}
<label for="email">Login:</label>
<input type="text" name="email" value="" id="email"/>
<label for="password">Password:</label>
<input type="password" name="password" value="" id="username">
<input type="submit" value="login" />
<input type="hidden" name="next" value="{{next|escape}}" />
</form>
urls:
(r'^login/$', login_view),
Problem: It works for users from default User model (username, password), but this form "doesn't know" users from MyUser model (email, password), it redirect them to /account/invalid page.
What am I doing wrong?
Thx!

You need to indicate your custom user model in settings:
AUTH_USER_MODEL = 'myapp.MyUser'
Also, you have to provide custom UserManager, from doc:
You should also define a custom manager for your User model. If your
User model defines username and email fields the same as Django’s
default User, you can just install Django’s UserManager; however, if
your User model defines different fields, you will need to define a
custom manager that extends BaseUserManager providing two additional
methods:

update user profile issue with post_save signal. errors a message are user already exists on update

I have extending user profile with profile model and create an post_save signal.

Django log user in using class based view

I am trying to log a user in, however, my view does not seem to work. The page is rendered and the form is displayed and everything. But when I enter a valid user name and password it just refreshes the page instead of going to success_url. I think it is the way I am implementing my view method. I do not think login(request, user_obj) is being accessed, and if so, so is request.user.is_authenticated().
I also include my login form using
{% if user.is_authenticated %}
{% include 'navbar_in.html' %}
{% else %}
{% include 'navbar_out.html' %}
{% endif %}
It only uses navbar_out.htmlso that is how I know my code is not accessing login(request, user_obj).
User model:
# Create your models here.
class Usermie(models.Model):
# associate fields with django built in user objects
# this provides the authentication that we would need from the django built in utilities
usermie_object = models.OneToOneField(User)
# form fields
id = models.AutoField(primary_key=True)
username = models.CharField(max_length=30, unique=True, blank=False)

# 1 call authenticate

# Return a user_obj object if the username and password are valid

<label>
<input type="checkbox"> Remember me
</label>
</div>

It might be that your user is not active and you don't handle that case. Try something like:
if user_obj.is_active:
login(request, user_obj)
return HttpResponseRedirect(self.success_url)
else:
return HttpResponse("Your account is inactive.")

Authenticate users with both username and email

I have extendted the UserCreationForm with email and other fields, so that I could authenticate a user with both its username and email.
forms.py:
class UserCreationForm(UserCreationForm):
class Meta:
model = User
fields = ('first_name', 'last_name', 'username', 'email',)
views.py:
def auth_view(request):
username = request.POST.get('username','')
password = request.POST.get('password','')
user = auth.authenticate(username=username, password=password)
if user is not None:
auth.login(request, user)
return HttpResponseRedirect('/')
elif:
user = auth.authenticate(email=username, password=password)
if user is not None:
auth.login(request, user)
return HttpResponseRedirect('/')
else:
return HttpResponseRedirect('/accounts/invalid_login')
html:
<form action="/accounts/auth/" method="post">
{%csrf_token%}
<label for="name">Email or Username:</label>
<input type="text" name="name" id="name" value="">
<label for="password">Password:</label>
<input type="password" name="password" id="password" value="">
<input type="submit" value="LOGIN">
</form>
In the views I tried giving both the username and email as input from the form as name, and check to see if username and password authenticate. If not then check whether email and password authenticate. But its not working. How do I solve this problem? Please kindly help me. Thank you.
You need to create an authentication backend: here is mine:
class EmailAuthBackend(ModelBackend):
"""
Email Authentication Backend
Allows a user to sign in using an email/password pair, then check
a username/password pair if email failed
"""
def authenticate(self, username=None, password=None):
""" Authenticate a user based on email address as the user name. """
try:
user = User.objects.get(email=username)
if user.check_password(password):
return user
except User.DoesNotExist:
try:
user = User.objects.get(username=username)
if user.check_password(password):
return user
except User.DoesNotExist:
return None
def get_user(self, user_id):
""" Get a User object from the user_id. """
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
Then in your settings:
AUTHENTICATION_BACKENDS = ('MyApp.backends.EmailAuthBackend',)
then create a custom view the uses the authenticate function.

login based on user roles

problem with my assignment....
I also need to make users login based on whether their role (usertype) is 'reader' or 'client' to be redirected to the proper welcome page. Plus i want to use my custom model (User's username & password) for login credentials. I have read the django docs custom auth but i still don't know i will implement it into my project.
models.py
class User(models.Model):
id = models.AutoField(primary_key=True, unique=True)
title = models.CharField(max_length='10')
surname = models.CharField(max_length='50')
firstname = models.CharField(max_length='50')
username = models.CharField(max_length='50', unique=True)
password = models.CharField(max_length='50')
email = models.EmailField(max_length='50')
phone = models.BigIntegerField(max_length='12')
city = models.CharField(max_length='50')
country = models.CharField(max_length='50')
usertype = models.CharField(max_length=13)
views.py
def login(request):
c = {}
c.update(csrf(request))
return render_to_response('login.html', c)
def auth_view(request):
username = request.POST.get('username', '')
password = request.POST.get('password', '')
user = auth.authenticate(username=username, password=password)
if user is not None:
auth.login(request, user)
return HttpResponseRedirect('adminwelcome')
else:
return HttpResponseRedirect('invalid')
template
{% extends "main.html" %}
{% block title %}Log In - {{ block.super }}{% endblock %}
{% block content %}
{% if form.errors %}
<p>Sorry, that is not a valid username or password</p>
{% endif %}
<form action = "auth_view" method="post"> {% csrf_token %}
<label for="username">Username:</label>
<input type="text" name="username" value="" id="username" />
<br />
<label for="password">Password:</label>
<input type="password" name="password" value="" id="password" />
<br />
<input type="submit" value="Login" />
</form>
<p>Not Registered? Create Account </p>
{% endblock %}
What i did was that when my User model form is being saved, it should get the username, password and email and create a user in the Django auth User table using this line of code
User.objects._create_user(request.POST['username'], request.POST['email'], request.POST['password'],False,False)
This is the full code in the views.py
def register(request):
if request.method == 'POST':
form = RegisterForm(request.POST)
if form.is_valid():
form.save()
User.objects._create_user(request.POST['username'], request.POST['email'], request.POST['password'],False,False)
# Redirect to the document list after POST
return HttpResponseRedirect('register_success')
else:
form = RegisterForm()
args = {}
args.update(csrf(request))
args['forms'] = RegisterForm()
return render_to_response('register.html', args)
Then for the login based on roles, I had to make the user a staff from the admin end by setting the 'is_staff' = true. After that, all i had to do was pass the 'is_staff==True' in the auth_view request during login authentication. A bit dirty but it does the trick. Any further optimization is appreciated. Cheers.
Views.py
def auth_view(request):
username1 = request.POST.get('username', '')
password1 = request.POST.get('password', '')
user = auth.authenticate(username=username1, password=password1)
#check if user has been set to staff (reader), redirect to reader welcome
if user is not None and user.is_staff==True:
auth.login(request, user)
return HttpResponseRedirect('readerwelcome')
#check if user is not staff(client), redirect to client welcome
elif user is not None:
auth.login(request, user)
return HttpResponseRedirect('clientwelcome')
#if login details not found, return error page
else:
return HttpResponseRedirect('invalid')

How can I get user's model fields 'first_name' and others? comment.email and comment.name gives me 'e-mail' field, comment.first_name gives me nothing. Thx!
According to built-in comment model documentation, you could access a user posted comment via {{ comment.user }} in your template. Consequently, you could access MyUser model fields like this {{ comment.user.email }} or {{ comment.user.first_name }}, etc.
