Autlib vs OAuthlib: Are these libraries the same?
I am a beginner in the world of the OAuth2.0 and OpenID Protocols. I would like to implement a custom server - provider for multiple applications. So, to use it for Single Sign-On (SSO). I would like to work with python. Till now I have found four packages, for an OAuth2.0 and an OpenID Connect server implementation, in Python: pyoidc, django-oidc-provider, Django OAuth Toolkit (DOT) by OAuthlib and Authlib. I tried to read and understand pyoidc, but it was not so helpful and easy, basic things were missing. I have tried django-oidc-provider and I was really satisfied, and the whole implementation was really easy. So, after those trials, I am left with Django OAuth Toolkit (by OAuthlib) and Authlib. Has anyone tried them? Are these packages the same? Is Authlib an updated version of the OAuthlib library? The only information I know till now, is that Flask-OAuthlib is deprecated, and Authlib is was its new version. *Every answer or advice or personal experience would be really helpful and always appreciated! Thank you again for your help. -

Django count sub-objects with ntext on SQL Server
I have a Claim object with ClaimAttachment with a simple foreign key. I want to filter Claims that have more than x attachments. Normally, I would just do: Claim.objects.annotate(att_count=Count("attachments")).filter(att_count__gt=5) Easy. Except that Claim has several ntext fields and that results in: django.db.utils.ProgrammingError: ('42000', '[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator. (306) (SQLExecDirectW)') That is because Django is making an outer join between Claim and ClaimAttachment and is grouping on all fields from Claim. Several of those fields being ntext, they can't be grouped by. I tried to work around the issue by doing a subquery myself: att = ClaimAttachment.objects.filter(claim_id=OuterRef("id")).aggregate(count=Count("id")) Claim.objects.annotate(att_count=Subquery(att)).filter(att_count__gt=5) But the aggregate cannot be done on the OutRef query. I can move the Count to the annotate(att_count=Count(Subquery(att))) but I'm back to square one because it's trying to group by all fields again. I know that this is not really Django's fault but rather another SQL Server annoyance but I don't control this data model, let alone the database server setup. How can I work around this limitation and get my attachment count ? -

Authentication bypassing using browser cookies in Django UI
I have a view in Django which renders html page. I need to do authentication before rendering the page. The link to open this page would be provided in another application built using groovy. On clicking the link, the UI should be rendered directly without any login page. At present I am using the @login_required decorator which opens the login page before rendering the UI. I want to bypass or use another mechanism which would do the authentication without showing the login page. PS: I don't have much knowledge regarding authentication. -

Grabbing object instance id from request.POST when using javascript e.preventDefault()
I am using a bootstrap modal to list object instances and perform CRUD operations. I wrapped the entire list in a form and pass the id of each object instances to the view using buttons names and value. When I delete the object without using Javascript, the view works fine, but as soon as I add the line e.preventDefault(); then the id of the object is not captured in the request anymore. why is that ? In more detail, the template looks like this: <form action="{% url 'delete_habit' %}" method="POST" id="deleteForm">{% csrf_token %} <div class="row"> <div class="col-12 pb-3"> <table class="modal-table border" id="habitsTable"> <tbody> {% for habit in habits %} <tr class="border js-row-{{habit.id}}"> <td class="border"> <img src="{% static 'img/bars_icon.svg' %}"> </td> <td class="text-left border px-3">{{habit.name}}</td> <td class="border"> <button id="delete-{{habit.id}}" type="submit" value="{{habit.id}}" name="habit_id" class="btn"> <img src="{% static 'img/minus_icon.svg' %}"> </button> </td> </tr> {% endfor %} </tbody> </table> </div> </div> </form> the view: def delete_habit(request): habit_id = request.POST.get('habit_id') --> this fails when e.preventDefault() data = {'habit_deleted': int(habit_id)} habit_to_delete = Habit.objects.filter(id=int(habit_id)).filter( user=request.user) habit_to_delete.delete() return JsonResponse(data) the javascript: var deleteForm = document.getElementById('deleteForm'); if (deleteForm !== null){ deleteForm.addEventListener('submit', function(e){ var formData = new FormData(deleteForm); e.preventDefault(); --> this empties the request (except the csrf token) var request … -
