I need help to integrate duo_python 2FA into Django-mama-cas
I've setup django-mama-cas as a primary central authentication server for serveral department websites. The websites reside in a drupal/php web framework and use phpCAS for the CAS client. I need to integrate duo_python somehow to the django-mama-cas server. I am not sure where to start and any advice on what files or classes to edit is what I am looking for. From what I imagine those [files, classes, etc] to be, are below: settings.py import os import ldap from django_auth_ldap.config import LDAPSearch, GroupOfNamesType, PosixGroupType # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

login_required decorator on a class based view in django
I have a working class based view. But when adding @login_required I get the error: AttributeError: 'function' object has no attribute 'as_view' Something is happening to the ResultListView here: from django.urls import path from .views import ResultListView urlpatterns = [ path('meetings/', ResultListView.as_view(), name='meetings'), ] My views.py: @login_required class ResultListView(ListView): template_name = ... def get_queryset(self): return Result.objects.filter(rider__user=self.request.user) Which is all working fine until I put the decorator in. Very confused now, I don't see why ResultListView should loose its attributes when sending it through the decorator. -
Get the last and unique element of the list based on date
Here is my data and code: [ (datetime.date(2020, 3, 25), 'Raport'), (datetime.date(2020, 3, 24), 'Raport'), (datetime.date(2020, 3, 23), 'Raport'), (datetime.date(2020, 3, 25), 'Document'), (datetime.date(2020, 3, 24), 'Document'), (datetime.date(2020, 3, 23), 'Document'), (datetime.date(2020, 3, 25), 'Analize'), (datetime.date(2020, 3, 24), 'Analize'), (datetime.date(2020, 3, 23), 'Analize'), ] Here is django (2.2) code: sorted(DataSet.objects.values_list('doc_type', flat=True).distinct(), reverse=True) I need to get the last and unique element of each document doc_type together with the date. At the moment I have the same list of documents: ['Raport', 'Document', 'Analize'] but I need: [(datetime.date(2020, 3, 25), 'Raport'), (datetime.date(2020, 3, 25), 'Document'), (datetime.date(2020, 3, 25), 'Analize')] Can someone provide me some hint?

Linking a model in Django
I have two models LeaveType and MyUser class LeaveType(models.Model): type_ = models.CharField(max_length=50, null=False, blank=False) total_leave_per_year = models.IntegerField(null=False, blank=False, default = 0) def __str__(self): return self.type_ Say, Leave types are: 1. Annual Leave of 20 days per year 2. Sick Leave of 5 days per year class MyUser(models.Model): dob = models.DateField(auto_now_add=True) leave = models.ForeignKey(LeaveType, on_delete=models.CASCADE, related_name="lms_leave_type") Now, When a user apply for an annual for 2 days then his/her remaining leave will be 18 days per year. Now how can I manage this? I have tried to use Inline ways but it does not work for me. Another method I tried is building another model containing user object, leave type object and his/her remaining leaves. Is this a better way or we have another better than this? Thank You. :) -

Django Quiz make it repeatable
I found this via google: https://github.com/sibtc/django-multiple-user-types-example I would like to change this quiz so that a checkbox asks if the quiz may be repeated when creating it. I have added the repeat in the models. class Quiz(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name='quizzes') name = models.CharField(max_length=255) subject = models.ForeignKey(Subject, on_delete=models.CASCADE, related_name='quizzes') repeat = models.BooleanField(default=False) and also ind the craete and updateview class QuizCreateView(CreateView): model = Quiz fields = ('name', 'subject', 'repeat', ) Now of course I would like the quiz to be repeated. For this purpose I have in the appropriate view: @method_decorator([login_required, student_required], name='dispatch') class QuizListView(ListView): model = Quiz ordering = ('name', ) context_object_name = 'quizzes' template_name = 'classroom/students/quiz_list.html' def get_queryset(self): student = self.request.user.student student_interests = student.interests.values_list('pk', flat=True) taken_quizzes = student.quizzes.values_list('pk', flat=True) queryset = Quiz.objects.filter(subject__in=student_interests) \ #.exclude(pk__in=taken_quizzes) \ .annotate(questions_count=Count('questions')) \ .filter(questions_count__gt=0) return queryset Here I have temporarily removed the corresponding exclude. Then I see the quiz in the list, but unfortunately I cannot call it up again. Now I get the template error: Exception Type: TemplateDoesNotExist Exception Value: students/taken_quiz.html How can I have the quiz repeated now? -

Web Application preferably in Django or Laravel with fingerprint detection
i got a project for school that asked me this stuff: It is a simple web application for fingerprinting users or visitors. Something similar as this one, except that we don't need to check if fingerprint is unique. https://amiunique.org/fp So the app should be modern and should respond to the visitor details of his device (OS, browser, IP address, country, city - this can be done via API /maxmind/... and some other information from device) Here you can use any framework as you want bootstrap or anything else... Design should be simple - in front page should have one button in the middle which says: Scan me or whatever, after clicking all results should appear on the page in organized way. Here is one example of front page: https://fingerprintjs.com/open-source/ The purpose of app is to detect if OS is outdated or browser is not latest version to inform user in some sort of windows. But that we can discuses later. Can you provide me some sources on how can i start this fingerprint thing, i have good knowledge of web developing html css js back-end and front-end, but implementing fingerprint is first time in my life. THANKS!!!! -
Django Model details displayed in the Bootstrap modal
Not sure if this question was asked before, but even that it is, it's out-dated, so pardon my repetition. I'll jump straight to it - I have a datable which is rendered from a complicated cross tabbed query, and it returns like 10 000+ rows, and in the very table I have a "detail" button which triggers a bootstrap modal, and when it opens it just shows some more unique details about the current object, or row. Now, the problem is, when the page where the table is, gets called, it takes so much time to load, it has 20 megabytes, which is a lot, and it takes like 5 seconds depending on the processor because every object gets loaded with his own modal (its happening inside the for loop). My question is, what is the best approach to load the details(bootstrap modal) only when the "details" button gets pressed. I tried something with Ajax, which was confused for me, so I would appreciate every suggestion. Thank you! This is the html of a table : % block content_row %} {% include 'partials/_alerts.html' %} <div class="card-body container-fluid"> {% include 'opportunity/opp_breadcrumb.html' %} <h2 class="-heading" style="margin-left: 50%">OPTIKA</h2> <table class="table table-bordered table table-hover … -

FDB connection on Python closes itself
I am using FireBird connector for Python in my django app. I have a single connection per session, in order to minimize the loading times and increase the efficiency, but whenever the connection is being alive for more than 10 minutes, the connection "closes" itself. It's quoted because it doesn't really close itself, the object connection is still alive and the attribute closed of the class is set to False. In this state, whenever you try to execute a query, and fdb.fbcore.DatabaseError is thrown. This is my connector class I use to create a connection: class DBConnector(object): def __init__(self): print("Init Connector") self.host = 'the_host' self.database = 'the_database' self.user = 'the_user' self.password = 'the_super_secret_and_secure_key' self.charset = 'the_most_common_charset' self.dbconn = None def create_connection(self): print("Creating Connection") connection = fdb.connect( host=self.host, database=self.database, user=self.user, password=self.password, charset=self.charset, ) return connection def __enter__(self): self.dbconn = self.create_connection() return self.dbconn def __exit__(self, exc_type, exc_val, exc_tb): self.dbconn.close() When I do con = DBConnector() cursor = con.cursor() cursor.execute(MY_SELECT) It works perfect. Now if i let the connection alive for more than 10 minutes and try again to execute a query: cursor.execute(ANOTHER_SELECT) It throws fdb.fbcore.DatabaseError: Error while preparing SQL statement:\n- SQLCODE: -902\n- Unable to complete network request to host .\n- Error writing … -

Travis CI failing flake8 tests despite flake8 tests passing on local development environment?
Background I am building a project using Django, Docker, Travis CI and Flake8. My flake8 file: [flake8] max-line-length = 119 exclude = migrations, __pycache__, manage.py, settings.py, env When I run local flake8 tests using: docker-compose exec app python manage.py test && flake8 I receive an ok message with no error messages. My code is good! The problem When I push my code to master which automatically starts Travis CI, the Travis build fails due to the following errors: ./project/settings.py:94:80: E501 line too long (91 > 79 characters) ./project/settings.py:97:80: E501 line too long (81 > 79 characters) ./project/settings.py:100:80: E501 line too long (82 > 79 characters) ./project/settings.py:103:80: E501 line too long (83 > 79 characters) ./core/models.py:7:80: E501 line too long (93 > 79 characters) ./core/models.py:13:80: E501 line too long (104 > 79 characters) ./core/migrations/0001_initial.py:18:80: E501 line too long (126 > 79 characters) The command "docker-compose run app sh -c "python manage.py test && flake8"" exited with 1. My flake8 file specifically states that the max line length is 119 so these errors should not be happening (like they are not when running the test on my local machine). Does anyone know whats going on? -

Is there a way to combine view functions of similar structures into one? Django
I'm a beginner at Django. Recently, I started writing a web app for inventory management and I realised that when i was writing the views, there were a lot of them with similar structures. For instance: def invoices(request): """The page for displaying invoices.""" invoice_list = Document.objects.filter(type_name__name='Invoice') page = request.GET.get('page', 1) paginator = Paginator(invoice_list, 10) try: invoices = paginator.page(page) except PageNotAnInteger: invoices = paginator.page(1) except EmptyPage: invoices = paginator.page(paginator.num_pages) context = {'invoices':invoices} return render(request, 'imsapp/invoices.html', context) and this one: def credit_notes(request): """The page for displaying credit notes.""" credit_notes_list = Document.objects.filter(type_name__name='Credit Note') page = request.GET.get('page', 1) paginator = Paginator(credit_notes_list, 10) try: credit_notes = paginator.page(page) except PageNotAnInteger: credit_notes = paginator.page(1) except EmptyPage: credit_notes = paginator.page(paginator.num_pages) context = {'credit_notes':credit_notes} return render(request, 'imsapp/credit_notes.html', context) So, I'm just thinking if there is a more elegant way to represent the above functions. Is class based view what I'm looking for? -

I just want to call the permission class in decorator as passed in argument. views.py ''' class MapViewSet(viewsets.ModelViewSet): serializer_class = MapSerializer @permission_decorator(permission_class=MapPermission) def get_queryset(self): return Map.objects.all() ''' utils.py ''' METHODS = {'GET': 'view_permission', 'PATCH': 'add_permission', 'POST': 'add_permission', 'PUT': 'add_permission', 'DELETE': 'delete_permission'} def check_user_permission(permission, user, tag): # logic here return True/False class CustomBasePermissions(permissions.BasePermission): @abstractmethod def has_permission(self, request, view): pass class PermissionError(APIException): status_code = status.HTTP_403_FORBIDDEN default_detail = {'message': "You Don't have required permission"} class MapPermission(CustomBasePermissions): def has_permission(self, request, view): if request.role == "owner": return True else: permission = METHODS.get(request.method) return check_user_permission(permission, request.user, 'map') ''' decorators.py ''' def permission_decorator(permission_class): assert permission_class is not None, ( "@permission_decorator() missing required argument: 'permission_class'" ) def decorator(func): func.permission_classes = permission_class return func return decorator ''' -
Python - Covert enum to Django models.CharField choices tuple
I have this enum: class Animal(Enum): DOG = 'dog' CAT = 'cat' and in a Django model I have this: possible_animals = ( ("DOG", "dog"), ("cat", "cat"), ) animal = models.CharField(choices=possible_animals, ...) I know I can use the enum like this: possible_animals = ( (Animal.DOG.name, Animal.DOG.value), (Animal.CAT.name, Animal.CAT.value), ) but is there any other elegant dynamic way to convert the enum into this kind of nested tuple?
