Allauth - How to disable reset password for social accounts? - django

I want social users are only able to login without password. Therefore, I want to disable password reset at /accounts/password/reset/ for social users.
I know that I need to add a conditional in this code at allauth.accounts.forms.py
class ResetPasswordForm(forms.Form):
email = forms.EmailField(
label=_("E-mail"),
required=True,
widget=forms.TextInput(attrs={"type": "email", "size": "30"}))
def clean_email(self):
email = self.cleaned_data["email"]
email = get_adapter().clean_email(email)
self.users = filter_users_by_email(email)
if not self.users.exists():
raise forms.ValidationError(_("The e-mail address is not assigned"
" to any user account"))
return self.cleaned_data["email"]
I'm thinking about this solution, but I don't know how to do it properly:
elif SocialAccount.objects.filter(provider='facebook'):
raise forms.ValidationError(_("You are using a social account.")

Allauth extendability is not a problem. self.users contain all users with provided email but if you have setting ACCOUNT_UNIQUE_EMAIL=True or just didn't change it (so it's True by default) then you can take just first user. Every user contain socialaccount_set related manager. So we just filter that set by provider name and if there is any item then this user has related socialaccount. So you can inherit allauth form and put additional check there:
# forms.py
class MyResetPasswordForm(ResetPasswordForm):
def clean_email(self):
email = self.cleaned_data["email"]
email = get_adapter().clean_email(email)
self.users = filter_users_by_email(email)
if not self.users.exists():
raise forms.ValidationError(_("The e-mail address is not assigned"
" to any user account"))
# custom code start
elif self.users.first().socialaccount_set.filter(provider='facebook').exists():
raise forms.ValidationError(_("You are using a social account.")
# custom code end
return self.cleaned_data["email"]
And then override allauth settings to use your form in their reset password view:
# your settings
ACCOUNT_FORMS = {
'reset_password': 'your_app.forms.MyResetPasswordForm'
}
I have not tested this code so it can contain typos so feel free to post any further questions.

#bellum answer is kind off right but now Allauth return a list on filter_users_by_email(email)
So this worked for me
from allauth.account.forms import SignupForm, LoginForm, ResetPasswordForm
from allauth.account.adapter import get_adapter
from django.utils.translation import ugettext_lazy as _
from allauth.account.utils import filter_users_by_email
class MyResetPasswordForm(ResetPasswordForm):
def clean_email(self):
email = self.cleaned_data["email"]
email = get_adapter().clean_email(email)
self.users = filter_users_by_email(email)
if not self.users:
raise forms.ValidationError(_("Unfortunately no account with that"
" email was found"))
# custom code start
elif self.users[0].socialaccount_set.filter(provider='google').exists():
raise forms.ValidationError(_("Looks like the email/password combination was not used. Maybe try Social?"))
# custom code end
return self.cleaned_data["email"]
Note: I am using google social authentication if you are using Facebook then change it to facebook.

Override Django LoginView Error Message With Custom AuthenticationForm

I have a class-based view that subclasses LoginView.
from django.contrib.auth.views import LoginView
class CustomLoginView(LoginView):
def get_success_url(self):
url = self.get_redirect_url()
return url or reverse_lazy('knowledgebase:user_home', kwargs={
'username':self.request.user.username,
})
I want to override the error message if a user's email is not yet active because they have to click a link sent to their email address. The current default message looks like this:
Instead of saying:
Please enter a correct email address and password. Note that both
fields may be case-sensitive.
I want to say something to the effect of:
Please confirm your email so you can log in.
I tried:
accounts/forms.py
from django.contrib.auth.forms import AuthenticationForm
from django.utils.translation import gettext as _
class PickyAuthenticationForm(AuthenticationForm):
def confirm_login_allowed(self, user):
if not user.is_active:
raise forms.ValidationError(
_("Please confirm your email so you can log in."),
code='inactive',
)
accounts/views.py
class CustomLoginView(LoginView): # 1. <--- note: this is a class-based view
form_class = PickyAuthenticationForm # 2. <--- note: define form here?
def get_success_url(self):
url = self.get_redirect_url()
return url or reverse_lazy('knowledgebase:user_home', kwargs={
'username':self.request.user.username,
})
The result is absolutely no effect when I try to log in with a user that does exist, but hasn't verified their email address yet.
AuthenticationForm docs.
Method - 1
Django uses ModelBackend as default AUTHENTICATION_BACKENDS and which does not authenticate the inactive users.
This is also stated in Authorization for inactive users sections,
An inactive user is one that has its is_active field set to False. The
ModelBackend and RemoteUserBackend authentication backends prohibits
these users from authenticating. If a custom user model doesn’t have
an is_active field, all users will be allowed to authenticate.
So, set AllowAllUsersModelBackend as your AUTHENTICATION_BACKENDS in settings.py
# settings.py
AUTHENTICATION_BACKENDS = ['django.contrib.auth.backends.AllowAllUsersModelBackend']
How much does it affect my Django app?
It doesn't affect anything other than the authentication. If we look into the source code of AllowAllUsersModelBackend class we can see it just allowing the inactive users to authenticate.
Method - 2
Personally, I don't recommend this method since method-1 is the Django way of tackling this issue.
Override the clean(...) method of PickyAuthenticationForm class and call the AllowAllUsersModelBackend backend as,
from django.contrib.auth.backends import AllowAllUsersModelBackend
class PickyAuthenticationForm(AuthenticationForm):
def clean(self):
username = self.cleaned_data.get('username')
password = self.cleaned_data.get('password')
if username is not None and password:
backend = AllowAllUsersModelBackend()
self.user_cache = backend.authenticate(self.request, username=username, password=password)
if self.user_cache is None:
raise self.get_invalid_login_error()
else:
self.confirm_login_allowed(self.user_cache)
return self.cleaned_data
def confirm_login_allowed(self, user):
if not user.is_active:
raise forms.ValidationError(
"Please confirm your email so you can log in.",
code='inactive',
)
Result Screenshot
You need to use AllowAllUsersModelBackend
https://docs.djangoproject.com/en/3.0/ref/contrib/auth/#django.contrib.auth.backends.AllowAllUsersModelBackend
Here you will get instruction for setting custom backend
https://docs.djangoproject.com/en/3.0/topics/auth/customizing/#specifying-authentication-backends
Hope it helps.
I'm not convinced setting up a custom backend is the solution when I simply want to override a message. I did a temporary fix by defining form_invalid. Yes it's hacky but for now, it'll do the trick. Doubt this will help anyone but it was interesting to discover form.errors. Maybe someone can build off this to solve their specific problem.
def form_invalid(self, form):
"""If the form is invalid, render the invalid form."""
#TODO: This is EXTREMELY HACKY!
if form.errors:
email = form.cleaned_data.get('username')
if User.objects.filter(email=email, username=None).exists():
if len(form.errors['__all__']) == 1:
form.errors['__all__'][0] = 'Please confirm your email to log in.'
return self.render_to_response(self.get_context_data(form=form))

Django allauth with email as username and multiple sites

Is it possible to use Django allauth with the authentication method set to 'email' when using it on multiple sites?
I'm aiming to allow a user with the email address bob#example.com to create an account at site1.com and a separate account at site2.com.
In order to use email authentication, I need to leave UNIQUE_EMAIL set to True in the settings but this prevents users who already have accounts in one site from creating accounts in the other site.
I am assuming you'd like to allow the same email to be registered separately for each of the sites in your Django setup.
Looking at the allauth code; it appears that it is infeasible to do so at the moment, likely because allauth does not take into account site ID as part of the User signup process.
class AppSettings(object):
class AuthenticationMethod:
USERNAME = 'username'
EMAIL = 'email'
USERNAME_EMAIL = 'username_email'
class EmailVerificationMethod:
# After signing up, keep the user account inactive until the email
# address is verified
MANDATORY = 'mandatory'
# Allow login with unverified e-mail (e-mail verification is
# still sent)
OPTIONAL = 'optional'
# Don't send e-mail verification mails during signup
NONE = 'none'
def __init__(self, prefix):
self.prefix = prefix
# If login is by email, email must be required
assert (not self.AUTHENTICATION_METHOD ==
self.AuthenticationMethod.EMAIL) or self.EMAIL_REQUIRED
# If login includes email, login must be unique
assert (self.AUTHENTICATION_METHOD ==
self.AuthenticationMethod.USERNAME) or self.UNIQUE_EMAIL
One way to do this would be as follows:
- Keep allauth AUTHENTICATION_METHOD as Username
- Store the site alongside the User information, perhaps in a UserProfile or by overriding the User Model.
- Make the combination of Email and Site unique.
- Override the LoginView such that the user enters email; you can translate the combination of Email, Site to a Unique User account and username; which you can pass on to allauth to perform login.
Assuming you use the Sites framework; your code would look something like this:
from allauth.account.views import LoginView
from django.core.exceptions import ObjectDoesNotExist
class CustomLoginView(LoginView):
def get_user():
email = request.POST.get('email')
current_site = Site.objects.get_current()
try:
user = User.objects.get(email=email, site=current_site)
except ObjectDoesNotExist:
pass # Handle Error: Perhaps redirect to signup
return user
def dispatch(self, request, *args, **kwargs):
user = self.get_user()
request.POST = request.POST.copy()
request.POST['username'] = user.username
return super(CustomLoginView, self).dispatch(request, *args, **kwargs)
Then monkey-patch the LoginView with the custom login view:
allauth.account.views.LoginView = CustomLoginView

How to use another field for logging in with Django Allauth?

I have successfully setup django-allauth along with a custom user model which let's users sign in directly using email and password or through Facebook, in which case email is taken from Facebook and saved in the Email field of the custom user model. I have also created a mobile field which stays empty as of now.
I want to allow users to log in using their Facebook, Email or MOBILE. Unfortunately that field is not unique=True in the model. I have thought of capturing the mobile and fetching the associated email address and then use that along with the password to log in any user.
However, I don't know how to extend the SIGN IN form that comes with django-allauth or the block of code that signs a user in where I can change it to meet my need.
As of now I don't find any of my current code relevant to this problem, but if it helps I am willing to provide it upon mention.
The following solution worked for me. I put the code in the forms.py file.
from allauth.account.forms import LoginForm
from auth_project import settings
class CustomLoginForm(LoginForm):
def __init__(self, *args, **kwargs):
super(LoginForm, self).__init__(*args, **kwargs)
if settings.ACCOUNT_AUTHENTICATION_METHOD == "email":
login_widget = forms.TextInput(attrs={'type': 'text',
'placeholder':
('Mobile Number'),
'autofocus': 'autofocus'})
login_field = forms.CharField(label=("Mobile"),
widget=login_widget)
self.fields["login"] = login_field
set_form_field_order(self, ["login", "password", "remember"])
def user_credentials(self):
credentials = {}
mobile = self.cleaned_data["login"]
login = CustomUser.objects.filter(mobile=mobile).values('email')[0]['email']
if settings.ACCOUNT_AUTHENTICATION_METHOD == "email":
credentials["email"] = login
credentials["password"] = self.cleaned_data["password"]
return credentials
# this is to set the form field in order
# careful with the indentation
def set_form_field_order(form, fields_order):
if hasattr(form.fields, 'keyOrder'):
form.fields.keyOrder = fields_order
else:
# Python 2.7+
from collections import OrderedDict
assert isinstance(form.fields, OrderedDict)
form.fields = OrderedDict((f, form.fields[f])
for f in fields_order)
Thanks.

error overiding save method while extending Django-registration app

I am using django-registration app. and have following code in forms.py
from django.contrib.auth.forms import UserCreationForm
from registration.forms import RegistrationFormUniqueEmail
from django import forms
from django.contrib.auth.models import User
from accounts.models import UserProfile
from pprint import pprint

user.userprofile.full_name = self.cleaned_data["fullname"]
user.email = self.cleaned_data["email"]
if commit:
user.save()
return user
I inherited from Django-registraion app's class RegistrationFormUniqueEmail so I when called save method at user = super(UserRegistrationForm, self).save(commit=False) it says, that save attribute doesnot exist. I actually wrote this code with inheritance from UserCreationForm .
I have just read the comment for SuperClass of RegistrationFormUniqueEmail that is :
"""

I just want to know that how can I override save() method or else how can I create new additional fields?
I have found solution of my own posted problem:
I have removed that django-registration app's RegistrationFormUniqueEmail, and instead I am inheriting from UserCreationForm and added the required method into my own UserRegistrationForm so I am able to override save method and able to do the things that I wanted to .

Django: Changing/Allowing User's login username to also use his/her e-mail

As my title says, I want to know if I there's a way to allow a user to use not only his username, but also his user's email to login. I want to standardize the login procedure because at the moment I'm having my users use many different conventions and it gets pretty messy.
You could probably do this if you enforce unique email addresses. Meaning no user can have the same e-mail address. This way you could fetch the user by e-mail address and log them in.
The form might look something like this:
<form method="post" action="{% url myproject.views.login %}">
<p>Username</p>
<input type='text' name='username'/>
<p>Password</p>
<input type='password' name='password'/>
<input type="submit" value="Login"/>
</form>
The view method might look something like this:
def login( request ):
username = request.POST['username']
password = request.POST['password']
user = User.objects.filter( email = username )[0]
if( user is not None ):
# -- the user was retrieved by an email address
# -- now you can authenticate and log them in log them in
from django.contrib import auth
user = auth.authenticate( user.username, password )
if( user is not None ):
auth.login( user, request )
OpenID might be another way to go: http://bit.ly/a2OlHX
Ensure unique e-mail addresses per user: http://bit.ly/aOaAbw
I think I 'solved' my problem, at least it's functional, for now.
I decided to use my own authentication backend. I created a file 'auth_backends.py' and added it to AUTHENTICATION_BACKENDS in my settings.py:
My login form fields only contain 'username' and password. The only way I'm doing to check if the entered username is in fact his username or email, is by doing the .find('#').
Is there a better way to check for it? Would this be enough?
The whole reason I'm doing this is because it's easier for the user to remember his/her email than his username (which is actually an 'id' consisting of numbers).
I'm also going to have to take care of duplicate emails.
