POST method of request returns the name whose value has been truncated after spaces
I am trying to create a calories app in which the user will select from a list of values (dropdown list) and then total calories consumed will be returned. Now I have a form in which there are certain food items and the user can select them and they will be added to food items consumed by the user in the database. The index.html file responsible for this action is as under: <div class="container"> <form method="POST"> {% csrf_token %} <select class="form-control" id="food_consumed" name="food_consumed"> {% for item in items %} <option value={{item.item_name}}> {{item.item_name}} </option> {% endfor %} </select> <button type="submit" class="btn btn-success m-3"> Add </button> </form> </div> The following view processes the data and stores it in the database: def index(request): if request.method == "POST": food_item_name = request.POST.get('food_consumed') food_item = FoodModel.objects.filter(item_name = food_item_name) food_consumer = request.user food_item_consumed = Consumer(food_consumer = food_consumer, food_consumed = food_item) food_item_consumed.save() food_items = FoodModel.objects.all() return render(request, 'CaloriesApp/index.html', context={'items':food_items}) However, I am encountering a weird error. The value of the food_item_name gets truncated after spaces, that is to say that for instance I have a food item called Egg, raw (147g), the name returned will be: "Egg,". However, when there are no spaces in food items names, there … -
Use django auth with WordPress
I want to make a website with Django as backend for most of the task, but for the frontend I want to use WordPress for page management and also to use Elementor as GUI page builder. But problem is that I want to make a single login system for both WordPress and Django with of course Django default user table. I have read a lot of articles about it they all somehow revolve wp-api but I don't require this in my case. I just want to sign-in into WordPress with Django table. And also if user is logged in into Django it must be logged into WordPress with same session (I am using same domain). -
Limit field permissions on Graphene Django
Lets say I got a user Type class UserType(DjangoObjectType): class Meta: model = User fields = [ "fieldA", "fieldB", "relationshipA", "relationshipB" ] And I want fieldB and relationshipB to be visible only to the owner (user). What is the best strategy to do this? Initially Ive created a PublicUserType excluding private fields, but quickly I realized that it might not be scalable because not only I'll have to create private representation for UserType I'll might also create private representation for any relationship (relationshipA etc), and proper resolvers, and duplicate fragments etc. Is there a best practice here? -
How to have a page/view have a different session duration in django?
I have a django project for which I must set the SESSION_COOKIE_AGE setting to 15 minutes, and I can not change that. In this project there also is a JS editor on a page: users can use the editor to make modification to something, and then hit the "save" button to save the result. The page is handled by a view. The editing can be time-consuming, so often happens that when the user clicks save, his session is already ended. How can I make that page and only that page have an unlimited session duration? Will a <script> making like a request each 5 min refresh the session successfully and keep it alive? -

How to serialize the many-to-many fields in DRF?
I have three tables in models.py: class literature_info(models.Model): pmid = models.CharField(primary_key=True,max_length=25) publication = models.CharField(max_length=50, blank=True, null=True) def __str__(self): return self.pmid class dataset_info(models.Model): dataset_id = models.CharField(primary_key=True,max_length=25) literature = models.ManyToManyField(literature_info, through='literature_dataset', blank=True) def __str__(self): return self.dataset_id class literature_dataset(models.Model): literature_info = models.ForeignKey(literature_info, on_delete=models.CASCADE) dataset_info = models.ForeignKey(dataset_info, on_delete=models.CASCADE) When I try to access the literature id from dataset_info table, I serialize the fields like this: class literature_info_serializer(serializers.ModelSerializer): class Meta: model = literature_info fields = "__all__" class dataset_literature_serializer(serializers.ModelSerializer): literature = literature_info_serializer(many=True) class Meta: model = dataset_info fields = ('dataset_id','literature',) It works well, and i get the literature info via dataset. Now I want to get the literature's datatset from literature_info table, i try to serialize the filed like this: class dataset_info_serializer(serializers.ModelSerializer): class Meta: model = dataset_info fields = ('dataset_id',) class literature_dataset_serializer(serializers.ModelSerializer): dataset_info = dataset_info_serializer(many=True) class Meta: model = literature_info fields = ('pmid', 'dataset_info',) However, it doesn't work this time.

The script launched by the apscheduler does not update the sqlite3 database on the server, but everything works ok on the localhost
I have a django application in which apschaduler periodically runs scripts that receive data from several emails and insert it into the sqlite3 database. When I run the project on localhost, everything is OK, but when I run it on the server, only the update_db_html function works.

ReactDOM not rendering in Django template
I am trying to integrate a React frontend into my Django project. I'm using Babel (ver 7.22) and webpack to bundle everything into index-bundle.js Currently, the index-bundle.js file is being fetched (according to the GET requests in terminal), but nothing is being loaded into the actual Django template. When I inspect the page, there is nothing from the js file being loaded. Everything was working until I tried adding in react components, but now nothing is working at all. File structure: -myproject --frontend ---index.js ---App.js --static ---css ---js ---index-bundle.js --templates my idex.js is literally just ReactDOM.render(<h1>help</h1>, document.getElementById("root")) I've already ensured that the template is loading the index-bundle.js file and has <div id="root"></div> -

Where is my blocking code? I do not receive WebSocket message - Django Channels
So I have setup a simple web app with Django Channels, that handles some WebSocket connections. It works almost perfect, however it does not receive messages, after I send messages initiated by another connection. This is my consumers: class CPConsumer(AsyncWebsocketConsumer): async def connect(self): self.cp_id = self.scope["url_route"]["kwargs"]["cp_id"] self.cp = charge_point(self.cp_id, self) await self.channel_layer.group_add(self.cp_id, self.channel_name) await self.accept() async def disconnect(self, _): await self.channel_layer.group_discard(self.cp_id, self.channel_name) async def receive(self, text_data): print(f"CP {self.cp_id} sent: {text_data}") await self.cp.route_message(text_data) async def get_config(self, _): print(f"CP {self.cp_id} updates firmware") await self.cp.call(call.GetConfigurationPayload()) print(f"CP {self.cp_id} sent response") class CPUserConsumer(AsyncWebsocketConsumer): async def connect(self): self.cp_id = self.scope["url_route"]["kwargs"]["cp_id"] await self.accept() async def disconnect(self, _): pass async def receive(self, text_data): print(f"User {self.cp_id} sent: {text_data}") await self.channel_layer.group_send(self.cp_id, {"type": "get.config"}) The CPConsumer isolated works perfect. It receives the messages, and routes them through the charge_point class. The charge_point object returns a message (it calls the consumers send method), and it is received by the client. So far so good. Now I want the CPUserConsumer to initiate a message to the connection in the CPConsumer. The charge_point object needs to handle sending that messages. So when the CPUserConsumer client sends a message, I can se that it is forward to the get_config method in the CPConsumer. The first … -

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).

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.

Adding fields to ModelForm programatically not showing in django admin
I have a usecase where I want to add fields to a modelform in django admin, but when trying to add them in the __init__function like this: class PackageFileInlineForm(forms.ModelForm): class Meta: model = File fields = '__all__' def __init__(self, *args, **kwargs) -> None: super().__init__(*args, **kwargs) self.fields['test'] = forms.CharField(max_length=100) Nothing shows up in the form. However if I do the form like this: class PackageFileInlineForm(forms.ModelForm): test = forms.CharField(max_length=100) class Meta: model = File fields = '__all__' Why does the init version not work? -
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.
