Django GraphQL subscription returns 400 Bad Request
I have a django v4.2.3 backend. Since graphene doesn't natively support subscriptions, I am using DjangoChannelsGraphqlWs (1.0.0rc6 pre-release version, since I need it to support my version of graphene). I have copy-pasted the default subscription given in the tutorial: class MySubscription(channels_graphql_ws.Subscription): notification_queue_limit = 64 event = graphene.String() class Arguments: arg1 = graphene.String() arg2 = graphene.String() @staticmethod def subscribe(root, info, arg1, arg2): return ["group42"] @staticmethod def publish(payload, info, arg1, arg2): """Called to notify the client.""" return MySubscription(event="Something has happened!") class Subscription(graphene.ObjectType): my_subscription = MySubscription.Field() defining the schema, like usual: schema = graphene.Schema(query=Queries, mutation=Mutations, subscription=Subscription) with a default consumer given in the tutorial class MyGraphqlWsConsumer(channels_graphql_ws.GraphqlWsConsumer): schema = schema async def on_connect(self, payload): print("New client connected!") This is the routing I used: urls.py urlpatterns = [ path("graphql/", csrf_exempt(GraphQLView.as_view(schema=schema, pretty=True, graphiql=True))) ] asgi.py application = channels.routing.ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": channels.routing.URLRouter([ django.urls.path("graphql/", MyGraphqlWsConsumer.as_asgi()), ]) }) I then tried to test my subscription using Apollo, Graphql Playground, etc. and always run into a similar error message: "Could not connect to websocket endpoint wss://paris2022.fr/graphql. Please check if the endpoint url is correct." Anyone has any idea what this can be? -
How to increase max redis channel layer load?
My websocket keeps disconnecting if I run a more resource heavy process. The websocket consumer processes a file and checks if it is in the correct format and returns and a status update, eg "Correct format", "Missing columns", etc. If I delete 20% of the rows from a file that caused the websocket to disconnect it works. I managed to narrow it down to around 500Kb is where the limit is. And also other consumers work too. CHANNELS: The issue occured when I changed from the dev InMemoryChannelLayer to RedisChannelLayer so thats why I think that the error is somewhere in that area and not with the specific consumer or process. The channel layers config is pretty simple, just the basic Redis example fromt the docs: CHANNEL_LAYERS = { "default": { "BACKEND": "channels_redis.core.RedisChannelLayer", "CONFIG": { "hosts": [(os.environ.get("REDIS_HOST"), 6379)], }, }, } I tried setting stuff like capacity, expiry, group_expiry, channel_capacity but nothing worked.\ REDIS: The redis server is running, if i do redis-cli ping it returns PONG. Configs: maxmemory: 0 tcp-keepalive: 300 maxclients: 10000 timeout: 0 ERROR: There isn't too much information in the daphne logs.

Packaged django apps installed from Pypi on new django project doesnt show the apps folders and files
In a former django project i have packaged an app for reusing it later in another django project. The app was packaged in both formats, source (tar.gz) and wheel and uploaded to Test Pypi. Then I have installed this app in a new project. Though the functionality of the app works... tested in the dev server, its files and folders are not shown in the VS Code editor, I would like to have them for editing purposes.

in ajax get a value upon clicking a button but it is in a loop

Adding fields to ModelForm programatically not showing in django admin

Django Multiple User's Authentication, SignUp Serializer and Views
I'm practicing creating multiple user types of authentication (in this scenario, Client and Driver like Uber) along with JWT. Currently, I am trying to write the SignUp Serializer for each corresponding user type (or if there is any more elegant way to do this), after signing up, I would love the user to have a Token.

Django IntegrityError: duplicate key value violates unique constraint ... DETAIL: Key ... already exists
In a Django app with Postgres db i have a model named Block. It is used in other models as ForeignKey class Block(models.Model): name = TranslatedField(models.CharField(max_length=200),) color = models.IntegerField(choices=BLOCKCOLOR_CHOICES, null=True, blank=True) blocktype = models.CharField(max_length=20, choices=BLOCKTYPE_CHOICES, default="break") def save(self, *args, **kwargs): self.name = self.name.capitalize() return super().save(self, *args, **kwargs) def __str__(self): return f"{self.name} ({self.blocktype})" I use django-translated-fields to translate the name in 4 languages. These are the relevant lines in admin: class BlockAdmin(TranslatedFieldAdmin, admin.ModelAdmin): pass admin.site.register(Block, BlockAdmin) I can create a new instance of Block in the admin interface and also in the view. When I edit the model and try to save I get the above mentioned error. It happens in the admin interface and in the view as well. I can manually delete the model and create a new one, it gets a new id. It doesn't matter if the model is already bound via ForeignKey to another model or if it's standalone. Can somebody give me an advice? Thank you in advance! I have tried manipulating the id in the database, as a final solution I have also deleted the database completely. It happens again. I have a feeling that it has something to do with the django-translated-fields package. … -
ORA-00955 error with django migrate but no tables in Oracle database
I'm trying to deploy a Django application on an Apache webserver and Oracle DB. When I get to trying to create the database tables using manage.py migrate I get an error ORA-00955: name is already used by an existing object. It doesn't tell me what the object is (which is frustrating). Looking at the database I don't have any tables in my schema. I have run migrate more than once due to an earlier failure, but there's nothing there that I can see (I'm looking at the database in DBeaver). I've tried SELECT table_name FROM all_tables WHERE owner = 'MYUSERNAME'; but that doesn't return anything. Is there some way to find out what the blocking object is? Is there some way to make migrate force its way through? What am I missing that means I can't see the tables that the database sees? -

Django - How to improve performance when model contains a large JSONField?
I am working on trying to figure out how to enhance performance when filtering on a queryset that has a JSONField with large data (thousands of lines). Even when querying and returning an estimated 100 objects, the return is extremely slow. 10-20 seconds. I have come to realize that the issue is the JSONfield, and the fact that large datasets are being stored in this field. I was reading about Djangos .only() and .defer() methods, because I don't need any data in this JSONField, but the performance seems to be the exact same without using these methods. I am just looking for some guidance on how to improve some performance here. -

Warning - Certain functionality requires requests_html, which is not installed
when I run my django server everything works fine. However right before the normal prompt that comes from running the server, I get this message Warning - Certain functionality requires requests_html, which is not installed.

Install using: pip install requests_html After installation, you may have to restart your Python session. And then my django server goes on and runs fine. I'm worried that when I deploy my website this error will be a problem. Btw I know where this is coming from. I'm using yahoo_fin and requests_html is a dependency, however I'm not using and won't use the yahoo_fin methods that require this dependency, so I guess what I'm asking is for a way to ignore this random Warning. I've tried installing the requests_html library but I still get the same error, even after I restart my Python session like the message says. -

Django Template Error: KeyError: "'test'=='test'" (string == string)
This one has even stumped Chat GPT who thinks there is nothing wrong with my code. I will slowly dissect my code till I get to the bottom of what is happening but given how bizarre it is, I wanted to document it here. I am building using Django and have a Django template. The main template calls a second template and it's on that second template the issue is happening: {% include "kb/select_file_dialog.html" %} {% if 'test'=='test' %} <script> var dialog = document.getElementById('my_modal_2'); dialog.showModal(); </script> This gives me the error: KeyError: "'test'=='test'" I have no idea why it thinks it's working with a dictionary. Without the problematic line {% if 'test'=='test' %} the code runs fine. -
