How to use Django roles for a SaaS product with an admin portal?
I would try to explain our desired product idea as clear as possible but feel free to ask further questions. So, basically what we want to build is a SaaS product that will be used by multiple clients. For now, we're not interested in custom domains like (cust1.myproduct.com, cust2.myproduct.com) and we will simply be using one database to manage all customers' data. So far so good. Our SaaS product will be sold to enterprise organizations which will then be used by their employees. So for any one customer organization, there are three types of roles that we would like to provide their users, as follows: Admin: An organization's admin that should be able to do all the settings for that particular organization Manager: An organization's manager that can manage the users that are under his/her team Employee: A normal user with bare minimal permissions that can only manage his own data Now, to provision customers for this SaaS product and to set their global settings (e.g. maximum allowed users, license type etc), we also plan to create an admin portal and APIs that will be used by our internal employees only. For this portal, we also want to define roles … -

How to set an owner of created object by default in DRF?
I want to save my car object with request.user as owner (field in Car model). My code: views.py class CarViewSet(viewsets.ModelViewSet): serializer_class = CarSerializer queryset = Car.objects.all() lookup_field = 'slug' permissions_classes = [IsAuthenticated] def perform_create(self, serializer): serializer.save(owner=self.request.user) def get_queryset(self, *args, **kwargs): print(self.request.user.email) print(self.request.user.is_authenticated) return self.queryset.filter(owner=self.request.user.pk) When I visit my frontend page, I have a list of my cars displayed. email and is_authenticated (True) fields are printed correctly. Everything is ok until I try to refresh the page - the data disappears and I get an error: print(self.request.user.email) AttributeError: 'AnonymousUser' object has no attribute 'email' is_authenticated field is set to False respectively. I have also tried including owner field to CarSerializer: owner = serializers.HiddenField(default=serializers.CurrentUserDefault()) But nothing changed. How can I fix that? -

How can I use function based view to make operations in a object with a modal?
I'm creating a website with a list of candidates where staff members can increment the grade of candidates by clicking in validate. I would like to increment the value of grade when I click on validate in the modal. It works because I can see in the admin panel that the grade of the candidate has been incremented but it does not redirect me in the list of candidates that was before. How can I do to redirect to the list of candidates that was before ? Here is the template displaying the list of candidates and the script displaying the modal : <table id="students-table" class="table"> <thead> </thead> <tbody> {% for student in student_list %} <tr> <td> <button type="button" class="validate-student bs-modal btn btn-sm btn-primary" data-form-url="{% url 'students:validate_grade' student.pk %}"> <span class="fa fa-eye"></span> </button> </td> </tr> {% endfor %} </tbody> <script type="text/javascript"> $(function () { $(".validate-student").each(function () { $(this).modalForm({ formURL: $(this).data("form-url")}); }); }); Here is the modal : {% load widget_tweaks %} <form method="POST" action=""> {% csrf_token %} <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel"><strong>{{ student.user.firstname }} {{ student.user.lastname }}</strong></h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> <p>Are you sure to validate this candidate ? ? </p> </div> <div class="modal-footer"> <button type="submit" … -

Django problem accessing a field from view in the autocomplete
I'm using django-autocomplete-light in my project, but I'm with some problems passing an argument from my view (the argument is also in my URL) to the autocomplete Select2QuerySetView. What is the correct way to do it?

Inside the Select2QuerySetView I'm always getting the value as None: class CalibrationAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): print(self.forwarded.get('period_id', None)) // Here I get None ... Can someone please help me with this? How can I get the period_id inside the Select2QuerySetView? Im struggling to find this solution. -

Conditional rendering of the Bookmark Button in React + Django Rest Framework
Hello? I am working on an ecommerce project and I want to render the Bookmark button conditionally to display that if a user saves a product the Bookmark button innerHTML changes from "Not Saved" to "Saved" in the frontend (React). The backend (Django) is working and user's bookmarks are being saved in the backend. In React I have used the following approach. {product.bookmarks && product.bookmarks.find(bookmark => bookmark.id === user.id) ? <p>Saved</p> : <p>Not Saved</p>} So it matches the Bookmark ID with the logged User's ID. The button is working and if a user saves a product it returns "Saved" in the frontend and if not saved it returns "Not Saved". Is this the best approach to use or there's a better method? I have also tried this approach in Django and it returns the data but I'm not sure how to use the data in React to render the button. @api_view(['POST']) @permission_classes([permissions.IsAuthenticated]) def add_bookmarks(request, id, *args, **kwargs): saved = bool product = get_object_or_404(Product, id=id) if product.bookmarks.filter(id=request.user.id).exists(): saved = False product.bookmarks.remove(request.user) else: saved = True product.bookmarks.add(request.user) data = { 'saved': saved } print(data) return Response(data, status=status.HTTP_200_OK) -

That also didn't work, so know I need help. -

Here is my code: #views.py def pull_feeds(request, pk): if request.user.is_superuser: source = Autoblogging.objects.get(pk=pk) url = requests.get(source.url) soup = BeautifulSoup(url.content, "html.parser") length = source.items items = soup.find_all('item')[:length] contents = soup.find_all('content:encoded')[:length] for i in range(length-1, -1, -1): content = contents[i].text title = items[i].title.text body = content[content.find('<p>'):] #the problem is here .. when i comment this, everything works fine category = Category.objects.get(pk=source.category.id) if not Post.objects.filter(title=title).exists(): post = Post(title=title, body=body, #the problem is here .. when i comment this, everything works fine category=category) link = content[content.find('src=')+5:content.find('alt')-2] img_data = requests.get(link).content with open('temp_image.jpg', 'wb') as handler: handler.write(img_data) with open('temp_image.jpg', 'rb') as handler: file_name = link.split("/")[-1] post.cover.save(file_name, files.File(handler)) os.remove("temp_image.jpg") return redirect("news:autoblogging") else: return HttpResponse("Sorry you are not allowed to access this page") Does anyone know how to fix this error? Thanks. -
What should be the error code 400 or 500, for the given scenario?
I am just starting on Django rest framework and i was creation a function based Rest API as below: @api_view('POST') def temp_view(request): #do something ..... ..... ..... command to copy a static file from a server if command fails: return Response ..... ..... return Response If my API fails at the 'copy command line' then what should be the status code for the response(400 or 500). And if 500 should i send error message as: command to copy ...file failed or is this not recommend to share any message with 500 error code? I know its a very naive question but i am bit confused. Thanks in advance. -
ChoiceFields to give two different forms or different fields in html template and django
I am trying to make a registration form for a dentist and a student, where I have a choice field for a dentist and a student. What I want to happen is, when dentist is picked, I should be able to see the specialties field in the html as well as Django to pick that form, and for student, to pick student_email and institution. I am confused to how to write its code in the template and I looked almost everywhere and couldn't find anything that could help with what I want.
