Rendering local web pages as an iFrame in Django
I have a view that uploads a zip file, checks if it contains an index.html file, and unzips it in a specific folder in the static directory. I want to be able to view this by going to a page where there is an iFrame pointing to this directory, and the user will be able to navigate inside this html page. But I can't seem to get it to work. Here is the function that uploads the zip file, and the view that uses it: views.py: @user_passes_test(lambda u: u.is_staff or u.is_superuser) def createCategory(request): if request.method == "POST": name = request.POST.get("name_kw") lang = request.POST.get("lang_kw") moduleid = request.POST.get("module_kw") zip = request.FILES.get("zip_kw") category = Category() category.name = name category.lang = lang category.module = Module.objects.get(id=moduleid) category.zip = zip category.created_by = request.user try: if zip.name.endswith(".zip"): rtn = publish_doc(category.name, zip) if rtn == "No index file found": messages.error( request, "Pas de fichier index.html détecté. Assuez-vous qu'un fichier index.html est présent dans votre fichier ZIP", ) return redirect("categoryList") else: category.root = rtn category.save() messages.success(request, "Catégorie créée avec succès") print("categorie et zip créées") return redirect("categoryList") else: messages.error( request, "Seuls les fichiers .ZIP sont acceptés", ) return redirect("categoryList") except IntegrityError: print("erreuuuuuuuur") messages.error( request, "Une erreur s'est produite.

Using templatetag "get_comment_list" from view, in Django comments?
I have a template expression {% get_comment_list for data.post as comment_list %}, it uses get_comment_list from Django-comments. It gets a list of comment objects for a specified object (in this case the Post object through data.post) However, I'm currently working on client side Ajax API to retrieve the comments and its related user data. So I cannot use the template html way to get/render the data, but in a view, Python script. I found that the tag get_comment_list is defined as follows: # django_comments/templatetags/comments.py @register.tag def get_comment_list(parser, token): return CommentListNode.handle_token(parser, token) I know how to import custom template tag to a view so Python can use it, like: @register.simple_tag def addFoo(value=""): return value + "Foo." The above type of tag is simply passing a string value, but the get_comment_list(parser, token) tag requires two parser thing and object thing object, it's not a plain string type. Now, I have no idea how I can construct that parser and token or pass a model to get_comment_list to get the comment objects. Is it possible to use this type of template tag in a view? Thanks. -
Connection to the postgres refused in Github Actions
I have a Django app with Postgres default database, running in docker. I also use Github actions as a CI.

Class-Based View of 'User' model auto-authenticates user
I've made a class-based view (DetailView) of app user's profile and for some reason anyone who visits the view is automatically considered authenticated even without entering any credentials. This happens without adding any extra logic in neither view nor template, just basic DetailView. The code is below: views.py from django.views.generic import DetailView from django.contrib.auth.models import User class ProfileDetail(DetailView): model = User template_name = 'index.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) return context urls.py from django.urls import path from .views import ProfileDetail urlpatterns = [ path('<int:pk>/', ProfileDetail.as_view()) ] template (index.html) {{ user.is_authenticated }} {# returns True #} {{ user }} {# returns the user with the corresponding id #} The question is why does Django do it and is there any way to circumvent it except of using function-based view? I've looked through the docs, but couldn't find an answer. -

Why LoginRequiredMixin don't stop my dispatch flow, when user is not authenticated
I have no clue why in this View, dispatch does not end after super(): class CreateBookView(LoginRequiredMixin, CreateView): template_name = 'library/create_book.html' form_class = BookForm def dispatch(self, request, *args, **kwargs): result = super().dispatch(request, *args, **kwargs) if self.request.user.is_authenticated and not self.request.user.contactform.is_completed: return redirect(reverse_lazy('edit_contacts') + f"?next={self.request.path}#edit") return result def form_valid(self, form): form.instance.owner = self.request.user form.instance.category = self._set_category(form) return super().form_valid(form) def get_success_url(self): pk = self.request.user.pk default_redirect = reverse_lazy('show_books_dashboard', kwargs={'pk': pk}) next_page = self.request.GET.get('next') return next_page if next_page else default_redirect @staticmethod def _set_category(form): category = form.cleaned_data.get('category') category_name = form.cleaned_data.get('category_name') if category or not category_name: return category new_category, created = Category.objects.get_or_create(name=category_name) return new_category But in this it works as I expected and end it: class DetailsNotificationView(LoginRequiredMixin, AuthorizationRequiredMixin, DetailView): model = Notification context_object_name = 'notification' template_name = 'common/notifications/notifications_details.html' authorizing_fields = ['recipient'] def dispatch(self, request, *args, **kwargs): result = super().dispatch(request, *args, **kwargs) notification = self.get_object() notification.is_read = True notification.save() if notification.offer: return redirect('show_offer_details', pk=notification.offer.pk) return result I expect LoginRequiredMixin to handle error immediately after super() when the user is not authenticated and stop dispatch flow. I cannot figure out why it does not work as expected in CreateBookView. Any ideas ? -

Django csrf token + react
I'm using django for my API and react for my frontend app. My problem is I do not know how to get csrf token which is needed to submit the login form (I do not need registrition form, just few users). This is the code for handling the /accounts/login : from django.contrib.auth import authenticate, login from django.http import JsonResponse from json import loads def login_user(request): body_unicode = request.body.decode('utf-8') body = loads(body_unicode) username = body['username'] pwd = body['pwd'] user = authenticate(request, username=username, password=pwd) try: if user.is_authenticated: login(request, user) email = User.objects.get(username=username).email return JsonResponse({"username":username, \ "pwd":pwd, \ "email":email }, \ status=200)` except Exception as expt: return JsonResponse({"error": str(expt)}, status=401) And in my react app I'm trying to make a request for logging /accounts/login using the X-CSRFToken header and the csrf token goten by the getCookie() function (found here), but it is always null and the response always rejected with 403 status code. Could you please show me how I can handle that situation please ? (I do not want to use csrf_exempt which pose security issues). -

what on_delete option to use in django app?
I have an Article model that allows admins to publish articles. Each article is assigned to a user that is creating this article. I want to make sure that all articles will stay untouched even if I delete the author of this particular article. I chose on_delete=models.DO_NOTHING to be sure that nothing except user account will be removed but I am not quite sure that is the most effective way. class Article(models.Model): id = models.AutoField(primary_key=True) author = models.ForeignKey(User, blank=True, null=True, on_delete=models.DO_NOTHING) title = models.CharField('Title', max_length=70, help_text='max 70 characters') body = models.TextField('Description') Question Should I use another option to use or DO_NOTHING is good enough. Obviously the most important to me is that author's name will be visible in the article after deletion and the article itself cannot be removed. -
Django admin prepopulated fields and fieldsets
I am using Django 3.2 I have the following model: class Foo(models.Model): title = models.CharField() slug = models.SlugField() # remaining fields listed below In Admin manager, I have the model: class FooAdmin(admin.ModelAdmin): fieldsets = [ ('General', { 'fields': [ 'title', 'description', 'information', 'cover_photo', 'gallery', ] }), ('Details', { 'fields' : [ 'is_cancelled', 'start', 'finish', 'video_url', ] }), ] prepopulated_fields = {'slug': ('title',), } admin.site.register(Foo, FooAdmin) When I attempt to create a new Foo in the admin manager, I get the error: KeyError: "Key 'slug' not found in 'FooForm'. Choices are: cover_photo, description, finish, gallery, information, is_cancelled, start, title, video_url." When I add the slug field to the list of fieldsets, it works, but then the slug field is shown on the form (which I don't want). I know that I can solve this by overriding Foo.save(), but I want the admin manager to handle this for me. So, how do I use fieldsets with prepopulated fields that are not supposed to appear on the form? -

python calculate rating by percent of complete
Let say, when student completed the course then he will get the percentage of his completion. Then we implement the max ratings is 5 stars which following these rules: 0%-4% => 0 star 5%-19% => 1 star 20%-39% => 2 stars 40%-59% => 3 stars 60%-79% => 4 stars 80%-100% => 5 stars So, based on student score: 0% percent complete will get 0 rating star. 10% percent complete will get 1 rating star. Also, another conditionals it can be 30% percent complete will get 2.5 rating stars. NOTE: The max 5 stars is dynamic value, it can be 10 stars. how we can accomplish this? -

Django Taggit - insert hyperlink if the word in body matches with tag
I am using django-taggit to handle tags in my app. I am also using django-ckeditor in my body field. I'd like to implement a function or a decorator or anything that will look at the text in the body field, find automatically tags in the text, and insert hyperlink like this one: http://127.0.0.1:8000/tag/test1/. I am not sure where should I start and how to implement such a feature. I know that CKEditor offers such a feature and it can be found here but I believe that I need a premium version of CKEditor5, right? If it is free is there any other way to handle CKEditor configuration than React, Angular, and Vue? Can I use Boostrap to for setting up the link feature?
