How to restrict AuthenticateCallbackView in django-microsoft-auth only to registered accounts?
I am using django-microsoft-auth in my Django project. I am trying to restrict this option only to registered users so only people who have already registered themselves are allowed to use Log in with Microsoft button. I found in AuthenticateCallbackView method called _authenticate. Code below: def _authenticate(self, code): if "error" not in self.context["message"]: if code is None: self.context["message"] = {"error": "missing_code"} else: # authenticate user using Microsoft code user = authenticate(self.request, code=code) if user is None: # this should not fail at this point except for network # error while retrieving profile or database error # adding new user self.context["message"] = {"error": "login_failed"} else: login(self.request, user) I am wondering how can I restrict authentication only to those who have accounts. In case someone doesn't have an account it would send a message: Please register your account first. -
django how to fetch upload folder path
I know how to upload multiple files through Django, but I have a problem when uploading a folder if there are subfolders in it. So I want the user to upload the folder and I get the root, dirs, and files of that folder the user upload.

Allow Celery Worker to consumes messages from non task queue
I have a django backend which is running Celery for distributed tasks. I have created a Service bus queue which stores temperature data coming from hundred of frontend devices. I am running Celery periodic task every 5 seconds to consume those messages. But the problem is the tasks will be scheduled even if there are no messages in the TEMPERATURE queue. Is there a way I can set up a Celery worker that can listen to the this queue and operate on it when there is a new task available? Keep in mind this queue is not a tasks queue. -

Data class serialization with blank string in Django
I have a data class in Django using the rest framework, that has a string field and a serializer for it. class Foo: string_field:str class FooSerializer(Dataclass): class Meta: dataclass = Foo My problem is that, if the string_field is blank, the serializer cannot be validated. The JSON I am calling with: {'string_field': ''} And the error: {'string_field': [ErrorDetail(string='This field may not be blank.', code='blank')]} Declaring the fields in the serializer and not using a data class is a solution, but I'd prefer to use the data class way if its possible. In my project I am using Django 3.0.5, Python 3.8 and 3.11 of the rest framework. -

Django: Create a dynamic sidebar template and use it in other templates
NOTE: This question is not about creating or using a base template! I'm creating a products app in my project, using only django and html/css, and all pages in this part has a sidebar nav menu that categorizes different product models and types. So this sidebar will be used in all other product pages. Inorder to categorize products, I've created this view for the sidebar: def sidebar_data(request): usage_queryset = Usage.objects.all() sub_usage_queryset = SubUsage.objects.all() main_model_queryset = MainModel.objects.all() pump_type_queryset = PumpType.objects.all() context = { "usage_queryset": usage_queryset, "sub_usage_queryset": sub_usage_queryset, "main_model_queryset": main_model_queryset, "pump_type_queryset": pump_type_queryset, } return render(request, "products/products_sidebar.html", context) And the sidebar template is as shown below: <ul class="nav flex-column list-unstyled my-3 ms-3"> {% for usage_item in usage_queryset %} <li class="nav-item p-2 ms-4"> <a href="#" class="text-decoration-none nm-text-color fw-semibold" data-bs-toggle="collapse" data-bs-target="#usage_{{ usage_item.usage_name_fa }}"> <i class="fa-solid fa-angle-left me-2 icon-selector"></i> الکتروپمپهای {{ usage_item.usage_name_fa }} </a> <ul class="submenu collapse" id="usage_{{ usage_item.usage_name_fa }}" data-bs-parent="#nav_accordion"> {% for sub_usage in sub_usage_queryset %} {% if sub_usage.usage == usage_item %} <li class="my-2 ms-4"> <a href="#" class="text-decoration-none nm-text-color fw-semibold"> {{ sub_usage }} </a> </li> {% endif %} {% endfor %} </ul> </li> {% endfor %} </ul> And now I'm creating a proucts main page for example, which should implement this sidebar.

how to filter by date with datetimefield in Django with MYSQL
Datetimefield in MYSQL cannot be filtered by date. class Data(models.Model): created_at = models.DateTimeField(default=timezone.now) As docs, it could be filtered by date: qs = Data.objects.fitler(created_at__date__lte='2022-01-01') It works fine with sqlite3, but it always return empty queryset with MYSQL. -
Override Django Slug
I have a blog in wagtail. Wagtail's default Page model already has a slug field defined. Full Example is here slug = models.SlugField( verbose_name=_("slug"), I have a Subclass AddStory of the Page class, so I am unable to define slug there. And I am getting a clashing error. Problem: The slug field automatically generates a slug from the Title. So There are some kind of event whose title will be same always. Like Jokes of the day, So for the first 10 or 20 days, editors will know that they have added 20 posts with day_1,day_2... at the end of the slug and when these days will increase it will be impossible for them to remember how many they have entered?! Probable Solution So if I can automate the slug as it will generate a slug from random ids or strings and it will be unique. I tried this in the subclass AddStory def pre_save(self): def randomid1(self): return(get_random_string(length=10)) self.slug = randomid1 How can I define that it will not generate slug from the title instead it will generate a slug from given random strings? -

django queryset filter with back reference
I'm a C++ developer and noob of python, just following django tutorials. I want to know how to filter queryset by its back references' information. Below is my models. # models.py import datetime from django.db import models from django.utils import timezone class Question(models.Model): pub_date = models.DateTimeField('date published') class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) Now, I want to get query set of Question which pub_date is past from now AND is referenced by any Choice. The second statement causes my problem. Below are what I tried. # First method question_queryset = Question.objects.filter(pub_date__lte=timezone.now()) for q in question_queryset.iterator(): if Choice.objects.filter(question=q.pk).count() == 0: print(q) # It works. Only @Question which is not referenced # by any @Choice is printed. # But how can I exclude @q in @question_queryset? # Second method question_queryset = Question.objects.filter(pub_date__lte=timezone.now() & Choice.objects.filter(question=pk).count()>0) # Not works. # NameError: name 'pk' is not defined # How can I use @pk as rvalue in @Question.objects.filter context? Is it because I'm not familiar with Python syntax? Or is the approach itself to data wrong? Do you have any good ideas for solving my problem without changing the model? -
Pass a variable to another function and render an html template at the same time in django
We want to access the same variable in every function inside our views.py. Since it is not constant, we cannot use it as a global variable. Is it possible to pass a variable to another function while also rendering an HTML template? What are the alternatives if none exist? This is our login function in views.py def loginpage(request): errorMessage = '' # Applicant Login if request.method=="POST": if request.POST.get('username') and request.POST.get('pwd'): try: currentUser=Applicant.objects.get(username=request.POST['username'],pwd=request.POST['pwd']) currentUser=Applicant.objects.get(username=request.POST['username']) first = currentUser.firstname middle = currentUser.middleinitial last = currentUser.lastname AppDashboard = ApplicantDashboardPageView(currentUser, request) except Applicant.DoesNotExist as e: errorMessage = 'Invalid username/password!' return render(request, 'home.html') The currentUser variable inside our login function is the variable we want to pass in this function def ApplicantdashboardPageView(currentUser, request): appPeriod = ApplicationPeriod.objects.all() exam = ExaminationSchedule.objects.all() posts = Post.objects.all().order_by('-created_on') form = PostForm() name=userNaCurrent print('from storeCurrentUser', name) if request.method == "GET": try: posts = Post.objects.all().order_by('-created_on') form = PostForm() #applicantID=currentUser.id #applicantNotification = Applicant.objects.get(id=applicantID) return render(request, 'applicantdashboard.html', context={'UserName' : name, 'posts':posts, 'appPeriod':appPeriod, 'exam':exam}) except ObjectDoesNotExist: return render(request, 'applicantdashboard.html', context={'UserName' : name, 'posts':posts,}) return render(request, 'applicantdashboard.html', context={'UserName' : name, 'posts':posts, 'appPeriod':appPeriod, 'exam':exam}) I am new to Django so please bear with me if my question seem too basic. Thank you
