I am trying to create a comment feature on my post .At initial level I just made a table comment and post.

Save data to Django's model from HTML form without forms.py
I'm trying to save some data to database from html form, not django's form. So I'm not using forms.py at all (I don't want to be blocked by all that abstraction and same fields in models.py and forms.py) So I'm using standard generic view like this #views.py class EnigmaView(LoginRequiredMixin, View): def get(self, request, *args, **kwargs): return render(request, "main/enigma.html") def post(self, request, *args, **kwargs): posted_data = request.POST if posted_data['type_'] == "暗号化": random_len = randint(3, 30) generated_pass_list = array.array("b", ()) for _ in range(random_len): numb = RandomNumber(1, 9).get() generated_pass_list.append(numb) data_to_encode = ''.join(str(e) for e in generated_pass_list) Enigma.decoded = posted_data['value'] Enigma.encoded = data_to_encode Enigma.save(self) return render(request, "main/enigma.html") and trying to save it to the model like this #models.py from django.db import models class Enigma(models.Model): encoded = models.CharField(max_length=100) decoded = models.CharField(max_length=100) def __str__(self): return self.decoded which throws me an Error AttributeError: 'EnigmaView' object has no attribute '_meta' Is this mean I need to define form in forms.py with MetaClass ? Is there a way to save thge data without it? -

Python Django - returning posts to a user based on their group
I am trying to create my own Learning Management System (LMS) as a project to learn a range of programming languages. So far users can login/logout and register. However what i want the system to do is to return a post to the user specific to the group I have assigned to them in the admin page. EXAMPLE user:'Steve' is assigned to group:'Maths' When 'Steve' logs in, if there are any posts assigned to 'Maths' then i want only those posts to be shown on their homepage. Further to this, if 'steve' is in other groups, I want posts from those groups to also be displayed. Below is html of the homepage which i have created. with this i can only show all posts to a user if they are in a very specific group. I understand that somewhere i will need to do some python programming to get this to work. If you need to see any more of my code I will be more than happy to provide. Thank You :) <div class="row"> {% for group_for in request.user.groups.all %} {% if group_for.name == "Science" %} {% for work in homework %} <div class="row"> <div class="col s12 m6 14"> … -
2 Forms on same model not saving as same user - Django

Last messages from every (sender, receiver) pair - django

Here is my code to generate that list: def get_queryset(self): users = set() msgs = Message.objects.filter(Q(sender=user) | Q(receiver=user)).order_by('-sent') res = [] for msg in msgs: if msg.sender == user and msg.receiver.id not in users: users.add(msg.receiver.id) res.append(msg.id) elif msg.receiver == user and msg.sender.id not in users: users.add(msg.sender.id) res.append(msg.id) self.queryset = Message.objects.filter(pk__in=res).order_by('-sent') Above code is working, but looking for more professional and clean python (django orm) code Is there any optimal solution?? -
get Django "self.request.user" with Token authentication
I have a Django Rest/ Vue.js application. I was using basic Django authentication but since it is a Single Page Application, I switched to Token Authentication so I can manage login/logout/register through an endpoint and get a more consistent application. Overall is working fine but my main problem is that I made some permissions and override some viewsets. I have to disable them in order to have my app to work with token authentication: My permissions: from rest_framework import permissions class IsOwnReviewOrReadOnly(permissions.BasePermission): def has_object_permission(self, request, view, obj): if request.method in permissions.SAFE_METHODS: return True return obj.restaurant_review.review_author == request.user class IsAuthorOrReadOnly(permissions.BasePermission): def has_object_permission(self, request, view, obj): if request.method in permissions.SAFE_METHODS: return True return obj.review_author == request.user And my viewset: class RestaurantReviewViewset(viewsets.ModelViewSet): queryset = models.RestaurantReview.objects.all().order_by("-created_at") def get_serializer_class(self): if self.request.method == 'GET': return serializers.RestaurantReviewGETSerializer else: return serializers.RestaurantReviewSerializer permission_classes = [IsAuthenticatedOrReadOnly,IsAuthorOrReadOnly] def perform_create(self, serializer): serializer.save(review_author=self.request.user) So my guess is that Django can't find request.user, is it related to my new authentication? Can Token Authentication provide it? -

Declare multiple Django relationships using the same column as the foreign key
Using Django ORM I want to declare multiple relationships that use the same column to reference entities from different tables. Though it looks quite strange it's a necessary measure. class First(models.Model): uuid = models.UUIDField(unique=True, default=uuid.uuid4) second = models.OneToOneField( 'Second', ondelete=models.DO_NOTHING, db_constraint=False, related_name='uuid', ) third = models.OneToOneField( 'Third', ondelete=models.DO_NOTHING, db_constraint=False, related_name='uuid', ) class Second(models.Model): first_uuid = models.UUIDField(primary_key=True) class Third(models.Model): first_uuid = models.UUIDField(primary_key=True) The code above doesn't work because Django complains it can't use the same column twice or something like this. Is there a legit way to do this without introducing additional columns? -

Cannot get Cookie value set by django
I have a page that refreshes with data based on cookie set by django. I am using XMLHTTPRequest with AJAX to refresh page. I have a view that should fetch data based on cookie but when get request is made to that url, request.COOKIE returns None not even csrf. How can I get cookie set by django in this scenario? Thanks
