Deploying Django Channels application to Heroku and setting Redis up
I've built a simple chat application in Django using Channels and Redis. Now I'm trying to deploy it to Heroku and I'm looking for some guidance on how to set up the Channel Layers using Redis. I've already deployed the application and tested it in the browser. I've managed to resolve my errors, and now the application is fully functional except for the messaging because I haven't set up a Redis server yet. I use Daphne as a web server if this provides any valuable information. I'm looking for an overview of all the steps I have to make to set up the Redis server, and how to configure the Channel Layers to work with it. I'd greatly appreciate any help on this, thank you in advance. -

Animated pictures in JavaScript, problem: flickering screen and resizing
As I mentioned in the title I have a problem properly embedding my animation in my Django project. At some point, I decided to update the logo used by my web page built-in Django. Having small experience with JavaScript I was looking for approaches that fit my needs. I built an animation engine having some inspiration from this StackOverflow answer. (Thanks to user gilly3). My approach is, though, different in this topic because I realised that if I would have a lot of pictures then sticking/concatenating them together in one file might be difficult. I've decided to use another approach and use a bunch of files instead of one. For that sake, I built a function with a generator which I could call in another function to display all pictures in order. This animation engine looks like this: function* indexGenerator() { let index = 1; while (index < 28) { yield index++; } if (index = 28) yield* indexGenerator(); }; var number = indexGenerator(); setInterval(function animationslider() { var file = "<img src=\"../../../static/my_project/logos/media/slides_banner_f/slide_" + number.next().value + ".jpg\" />"; document.getElementById("animation-slider").innerHTML = file; $("#animation-slider").fadeIn(1000); }, 100); $("#animation-slider").fadeIn(1000); doesn't do the trick with values from 10-1000. I record what this looks like: https://youtu.be/RVBtLbBArh0 I … -
Protecting Rest API Routes against expired token using Django Rest Framework and JWT Authentication
I am pretty new to Django Rest Framework and I have created JWT Authentication. I have set the access token expiry time to 4 seconds. After when the token expires, I am still able to access the API route. It is not restricting me, nor it is throwing any error such as 401 unauthorized. Please someone help if you can. This is my SimpleJwt settings: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_simplejwt.authentication.JWTAuthentication', ) } SIMPLE_JWT = { 'ACCESS_TOKEN_LIFETIME': timedelta(seconds=4), 'REFRESH_TOKEN_LIFETIME': timedelta(days=90), 'ROTATE_REFRESH_TOKENS': True, 'BLACKLIST_AFTER_ROTATION': True, 'UPDATE_LAST_LOGIN': False, 'ALGORITHM': 'HS256', 'SIGNING_KEY': SECRET_KEY, 'VERIFYING_KEY': None, 'AUDIENCE': None, 'ISSUER': None, 'JWK_URL': None, 'LEEWAY': 0, 'AUTH_HEADER_TYPES': ('Bearer',), 'AUTH_HEADER_NAME': 'HTTP_AUTHORIZATION', 'USER_ID_FIELD': 'id', 'USER_ID_CLAIM': 'user_id', 'USER_AUTHENTICATION_RULE': 'rest_framework_simplejwt.authentication.default_user_authentication_rule', 'AUTH_TOKEN_CLASSES': ('rest_framework_simplejwt.tokens.AccessToken',), 'TOKEN_TYPE_CLAIM': 'token_type', 'TOKEN_USER_CLASS': 'rest_framework_simplejwt.models.TokenUser', 'JTI_CLAIM': 'jti', 'SLIDING_TOKEN_REFRESH_EXP_CLAIM': 'refresh_exp', 'SLIDING_TOKEN_LIFETIME': timedelta(seconds=4), 'SLIDING_TOKEN_REFRESH_LIFETIME': timedelta(days=90), } This is my route which I am protecting against expired tokens: @api_view(['GET']) @permission_classes([IsAuthenticated]) def get_notes(request): user = request.user notes = user.notes_set.all() serializer = NoteSerializer(notes,many=True) return Response(serializer.data) -
Can I iterate my context at view to put into my template?
I've created this function at my views to iterate through my pages. for chapter in chapters: context["chapter_page"] = math.ceil((changelogs.index(changelog) + 1) / 2) context["chapter"] = chapters return context I am still making a for a loop in my template, so I cannot remove him. I added this context, but the only returned page is the last page, which means, that my context["chapter_page"] is not iterating. {% for chapter in chapters %} <li> <a href="?page={{ chapter_page }}&#{{ chapter.number }}"> {{ chapter.number }} </a> </li> {% endfor %} Of course, I could not add this logic direct to my template, it is not accepted by Django. {% for chapter in chapters %} <li> <a href="?page={{ math.ceil((chapters.index(chapter) + 1) / 2) }}&#{{ chapter.number }}"> {{ chapter.number }} </a> </li> {% endfor %} I am expecting to do a loop and return each iterated number at my href=page -
Referencing a specified attribute in a model using related field
Assuming you have a Person model with attributes id and username amongst others. class Person(models.Model): id = models.AutoField(primary_key=True) username = models.CharField(unique=True) # other fields In Django Rest Framework there exists the PrimaryKeyRelatedField which represent the target of the relationship using its primary key. When using it in a serializer, it would look something like this class PersonSerializer(serializers.Serializer): id = serializers.PrimaryKeyRelatedField( queryset=User.objects.all(), ) username = serializers.CharField(required=True) However I would like a field that would target the username as well. Something similar to class PersonSerializer(serializers.Serializer): username = UsernameRelatedField(queryset=User.objects.all()) One potential solution I have come across is creating a custom relational field but it doesn't seem to work as expected. I would like to check if a username exists for a user. -

How to insert an item into a Queryset which is sorted by a numeric field and increment the value of the field of all subsequent items
Let´s say, there is a Django model called TaskModel which has a field priority and we want to insert a new element and increment the existing element which has already the priority and increment also the priority of the following elements. priority is just a numeric field without any special flags like unique or primary/foreign key queryset = models.TaskModel.objects.filter().order_by('priority') Can this be done in a smart way with some methods on the Queryset itself? -

'DateField' object has no attribute 'value_from_datadict'
