Extend User model in Django with jwt authorization
I am trying to extend User model in Django. I already have authorization using jwt Token and I am currently trying to add another field to User model, such as phone number and address. My views.py looks like this: class MyObtainTokenPairView(TokenObtainPairView): permission_classes = (AllowAny,) serializer_class = MyTokenObtainPairSerializer class RegisterView(generics.CreateAPIView): queryset = User.objects.all() permission_classes = (AllowAny,) serializer_class = RegisterSerializer models.py like this: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) phone_number = models.IntegerField(blank=False) address = models.CharField(max_length=500, blank=True) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() In here I'm trying to create another class that will store phone number and address. How can I incorporate my Profile class into User so that it will create new user model and what is more use earlier implemented Token authorization. -
Multiple nested choices in Django models
Forgive me if I'm not describing this correctly - I'm still learning and I've hit a wall with a problem I'm working on. I want to create a way (in the Admin backend for now) for users to show the books they like by fiction/non-fiction, age-range, genre(s) and sub-genre(s). So, a user who liked gothic horror books could select fiction>adult>horror>gothic. Or, a user who likes literally all YA books could select fiction>Young Adult and their selection would cascade down to every genre and sub-genre. I think the Choices field option and the MultiSelectField functionality might be a start, but there doesn't seem to be a way to add 'layers' to the choices beyond the categories below, and it seems like an inelegant solution when there could be hundreds of choices. I also don't know how it could be presented in the Admin - ideally with checkboxes that can 'open up' to show the sub-categories beneath them. GENRE_CHOICES = ( ('Fiction', ( ('FCH', 'Childrens'), ('FMG', 'Middle Grade'), ('FYA', 'Young Adult'), ('FAD', 'Adult'), )), ('Non-Fiction', ( ('NCH', 'Childrens'), ('FMG', 'Middle Grade'), ('FYA', 'Young Adult'), ('FAD', 'Adult'), )), ) genres = MultiSelectField(max_length = 100, choices=GENRE_CHOICES, null=True) I don't even know the name of … -

How do you pass options to Django-flatpickr date picker?
Im trying to implement a datetime picker on a Django app but im having some trouble working out how to pass options to the picker using the django-flatpickr package -->docs here: django-flatpickr. The docs really just get you started but don't go into any detail on how to apply some options and filter provided by the flatpickr.js package. I have successfully implemented the basics with the form fields and passing it to and from the the template which all works fine. However im having difficulty passing options i.e a start date, end date, allowed dates, making sure dates can't be selected I the past etc So the backend: forms.py class DatePickerForm(forms.Form): id = forms.CharField(widget=forms.HiddenInput) date_from = forms.DateTimeField(widget=DateTimePickerInput()) date_to = forms.DateTimeField(widget=DateTimePickerInput()) amount = forms.TypedChoiceField(choices=PRODUCT_QUANTITY_CHOICES, coerce=int) views.py def check_availability(request): #Get date time vals from client, pass to check_availabilty to query db if request.method == 'POST': form = DatePickerForm(request.POST) if form.is_valid(): cd = form.cleaned_data availability = check_availability(cd['id'], cd['date_from'], cd['date_to'], cd['amount']) else: print('Not bloody valid') return HttpResponse(f'Availabilty = {availability}') ClientSide: mytemplate.html <form action="{% url 'check_availability' %}" method="post"> {{ date_form.media }} {{ date_form.as_p }} <input type="hidden" name="id" value="{{ rental.id }}"> {% csrf_token %} <br> <button type="submit" value="Check Dates">Check Availability</button> </form> So what im really looking … -

Django + Django Rest Framework: get correct related objects on intermediate model
I have an intermediate model with the following fields: class UserSkill(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) skill = models.ForeignKey(Skill, on_delete=models.CASCADE, related_name='user_skills') disabled = models.BooleanField(default=False) As you can see, it has two foreign keys, one to the auth user and one to another table called skill. I am trying to get all Skills assigned to an specific user, so I do the following get_queryset in my ViewSet: class AssignedSkillViewSet(viewsets.ModelViewSet): queryset = Skill.objects.all() serializer_class = AssignedSkillSerializer permission_classes = [permissions.IsAuthenticated] def get_queryset(self): user = self.request.user return Skill.objects.filter(user_skills__user=user, user_skills_user__disabled=False)) Now, I also need to include the intermediate model information in the API, which I can access trough users_skills related name in DRF's Serializer, as follows: class AssignedSkillSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Skill fields = [ 'id', 'url', 'title', 'description', 'user_skills', ] But when I try to get that information it returns ALL user_skills related to the assigned skill, no matter if they are assigned to other users. I need the related model information only for that user and that skill. For Example: If I have a skill named Math, and a user named Maria related_skills = Skill.objects.filter(user_skills__user=user, user_skills_user__disabled=False)).user_skills.all() The above code will return: [ <UserSkill: Math+Jenniffer>, <UserSkill: Math+Gabriel>, <UserSkill: Math+John>, <UserSkill: Math+Maria>, ] I only … -

Manually caching a view in Django
I'm using Django 4.0 and I have some few pages that takes a bit to load since they have to load lots of stuff from the database. These pages are static, they never change, and I don't want the users to wait, so I want to cache them as soon as the server goes up. Unfortunately I'm not finding a way to do so (I tried the @cache_page decorator, but it only caches the page after the first visit). How could I accomplish this? Thank you. -

How to set the custom UserModel field value upon creation of the user in Django?
I have a custom UserModel which has a CharField named as pbc_id. I want it to be set as something like below: pbc_id = "PBC-" + str(user.pk) In other words, I want to attach the newly created user's primary key value at the end of the string "PBC-" and then assign this value to the pbc_id field.

Django rosetta problem with changing translations
I am using django-rosetta for translations in my django project and have problem with changing translations using rosetta admin page. On the development environment everything works great. Problem appears on production server where django is run with gunicorn and it's probably related to cache settings in Django. So lets say i have a html file with translated string "Hello" displayed. Word "Hello" is translated to "Witaj", so when i open page in my local language i'll get displayed "Witaj". Then I change this translation to "Cześć" ("Witaj" -> "Cześć") and hit "Save and translate next block" button. Then there is an interesting part. When i reload this page on my local language settings i'll get displayed randomly one of "Witaj" or "Cześć". I've been reading about it and found something like that in rosetta docs Please make sure that a proper CACHES backend is configured in your Django settings if your Django app is being served in a multi-process environment, or the different server processes, serving subsequent requests, won’t find the storage data left by previous requests. and then TL;DR: if you run Django with gunicorn, mod-wsgi or other multi-process environment, the Django-default CACHES LocMemCache backend won’t suffice: use memcache … -

Referencing Attribute from Separate Class/Model
Using Django and PostgreSQL. I'm building a media streaming website. Where I have a Video class/model referencing back to a Broadcaster class/model. I'm attempting to grab an attribute (name) from the Broadcaster class and reference it as either the default value or directly from the ForeignKey relationship. Whenever I try to access/reference the attribute I get "<django.db.models.fields.related.ForeignKey>" Picture of ForeignKey Jargon when referencing Video model/class attribute broadcaster_name. (default=Broadcaster.name) BUT only when using broadcaster_name located in the Video class/model. Instead of the attribute reference of 'video.broadcaster.name', which is the goal. Below is my Python/Django code: ''' class Broadcaster(models.Model): member = models.OneToOneField(Member, on_delete=models.CASCADE, null=True) name = models.CharField(max_length=50, unique=True, null=True) def __str__(self): return str(self.name) def get_name(self): return f'{self.name}' ''' ''' class Video(models.Model): broadcaster = models.ForeignKey(Broadcaster, on_delete=models.CASCADE, null=True) broadcaster_name = models.CharField(max_length=50, default=Broadcaster.name) ''' I've tried several different approaches with no avail... Below is my HTML/Django code: ''' {% for video in media_list %} <div class="card"> <img class="cover_img" src="{{ video.cover_img_url }}" alt="Cover Image"> <p></p> <h2>{{ video.title }}</h2> {# Works #} <h2>{{ video.broadcaster }}</h2> {# Doesn't Work #} <h2>{{ video.broadcaster.get_name }}</h2> {# Doesn't Work #} <h2>{{ video.broadcaster.name }}</h2> {# Doesn't Work #} <h2>{{ video.broadcaster_name }}</h2> {# Returns Object/ForeignKey Jargon #} </div> {% endfor %} ''' Similar … -
respond on post request to the third side, csrf token
I have two servers on Django, each server has its client. I need to send the request from one server to the second. I do it like this: def post(self, request, serial_number): if settings.DEBUG: setattr(request, '_dont_enforce_csrf_checks', True) charger_id = Charger.objects.get(serial_number=serial_number) form = WiFiConfigForm(request.POST) ip = charger_id.public_ip_address if form.is_valid(): data = {"wifi_ssid": request.POST.get('wifi_ssid'), "wifi_pass": request.POST.get('wifi_pass')} url = "http://127.0.0.1" + ":" + PORT + "/wifi_config/" + str(serial_number) + "/" client = requests.session() client.get(url) csrf_token = client.cookies['csrftoken'] payload = { 'csrfmiddlewaretoken': csrf_token } # response = requests.post(url, data=payload) # I tried this variant as well response = client.post(url, data=payload) print("response:", response) else: return Response("Form is not valid", status=status.HTTP_200_OK) return Response({"response": "response", "ip": ip, "serial_number": serial_number}, status=status.HTTP_200_OK) The problem is in csrf tokens, I don't know how to deal with them. The error is KeyError: "name='csrftoken', domain=None, path=None"
