I'm using rest_framework_simplejwt.authentication.JWTAuthentication in Django to create tokens for our users.
But some users have limited user permissions[in the admin panel]. For example they only allow to get articles and nothing else. But the token that simplejwt creates allow user to get all other data as well.
Is there a way to adjust it? I think simplejwt overwrites the Django permissions.
The token is used just for Authentication purposes, not for Authorisation purposes. You need to use permissions for assigning permissions to different users. Read about django permissions here. If you need to customize permissions, you can extend DjangoModelPermissions class.

I've got a Django site with authentication handled by Auth0 (following this quickstart guide). The issue I have is that users logged in don't have access to Django Admin section:
How can I assign certain Auth0-authenticated users the privileges to login Admin? Somehow link them with current Django-based users perhaps?
You need to use Auth0 roles, or extra data.
The flow works like this:
Log into Auth0 and add in roles or extra data to your user
Create a Django backend in your authentication pipeline to read in the roles/extra data infomration
Have your backend will check this role information and add set "is_staff" to True for the user
I want make sign up and login on the base of their role there admin can add users and approved the request of other two user so that they can login.When user click on the sign up the user see sign up page accorading to their roll and same for login .
Django implements a pretty decent authentication framework inside it, so you already have things such as Users, Groups and Permissions to work on. All of those being managed easily by the admin page.
What you want to do is to assign a set of groups/permissions to a newly created user to determine its role and then build a frontend that manages the different kind of users in terms of templates. If you want an user to have itself validated before start using your page, refer to the is_active attribute of the User object.

I'm using django-allauth for my Django web app. How can I ban certain users from logging in or restrict certain actions after they log in for a period of time?
Should I just deactivate their accounts outright? What are some good solutions?
Normally for django authentication you would set the user object's is_active attribute to False and the user wouldn't be able to log in (into django admin for example). But you're using allauth, so by simply setting the is_staff attribute would be enough to block them from entering django admin for example.
Now, if you're implementing another type of frontend dashboard or need to set rules to how a user logs in, I'd say for you to use AccessMixins if you're using CBVs or decorators if you're using FBV. Specially the UserPassesTest mixin and user_passes_test decorator. With them you can check if a user comply to a certain rule and then allow them to log in or not. Check the docs here.
I've been working on a Django app that authenticates against an LDAP. I've created permissions and groups in the admin interface. In development mode I have both back-ends active
AUTHENTICATION_BACKENDS = (
'django_auth_ldap.backend.LDAPBackend',
'django.contrib.auth.backends.ModelBackend',
)
Django tries authenticating across all of its authentication back-ends. Regardless of where it succeeds it uses the ModelBackend Authorization (permissions and groups) granted to the users.
But when disabling 'django.contrib.auth.backends.ModelBackend' Django does not use the standard Authorization methods. In production environment I want users to authenticate against LDAP only.
My question:
Is there an option to disable ModelBackend authorization but still use ModelBackend Authorization.
EDIT
First note in the docs of django-auth-ldap :
Note LDAPBackend does not inherit from ModelBackend. It is possible to use LDAPBackend exclusively by configuring it to draw group membership from the LDAP server. However, if you would like to assign permissions to individual users or add users to groups within Django, you’ll need to have both backends installed:
But I'm still puzzled. There is no technical reason for this. When both backends activated, and authenticating against LDAP, Django is still able to use the Django permissions.
This was asked quite a while ago, so I hope you found an answer... but to help anyone else who may stumble across this:
"The permissions given to the user will be the superset of all permissions returned by all backends. That is, Django grants a permission to a user that any one backend grants."
https://docs.djangoproject.com/en/1.11/topics/auth/customizing/#handling-authorization-in-custom-backends
This means that it is falling through and checking all permissions/perms methods in all of the backends, even though you were authenticated using the LDAPBackend, Django is pulling permissions/perms from LDAPBackend + ModelBackend and grouping them all together.
If you REALLY REALLY want to be SURE that ModelBackend.authenticate() is never called, you could always just make your own class MyAuth(ModelBackend) inheriting from ModelBackend and override authenticate in that to just always return None. Then you would include this in your settings.py file.
I have a range of models for my Django project. Everyone with a login has a Profile. A Profile will have certain permission access to the different parts of the website... Be able to view or edit certain accounts in the Account model. Be able to view or edit certain accounts in the Module model. Be able to delete or be blocked from accessing other Profiles. etc. People with Profiles do not access the normal Django built-in admin, it's all a custom website-side area where all of this stuff will take place.
Django's built in permissions stuff didn't seem to cover this sort of module/row level permissions. I was thinking of having a simple Permissions model with Profile and Permission Type foreign keys in them. Then all the things I want to be accessable only by Profiles with permissions will have a many to many to this Permissions model. But I'm not sure that's how to go about it?
What is an ideal way of doing permissions for the profiles to restrict access to rows of other models?
Check out Florian Apolloner's Django Advent post on Object Permissions. I found it to be a decent way of doing object-level permissions.
