I'm getting this error when trying to get the image attribute and set some values according to the content of service_name attribute, both service_name and image_url are attributes of the same model, but I want to set the image according to the content service_name using condition statements.

AllowAny CreateAPIView returns 401 for unauthenticated users
I use DRF with djangorestframework-simplejwt package. In my settings.py: INSTALLED_APPS = [ ... 'rest_framework', ... ] ... REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.AllowAny', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_simplejwt.authentication.JWTTokenUserAuthentication', ), } SWAGGER_SETTINGS = { 'SECURITY_DEFINITIONS': { 'Bearer': { 'type': 'apiKey', 'name': 'Authorization', 'in': 'header', 'description': 'E.g. \'Bearer jwt.token.here\'' } } } And in my apps' views.py: ... class PublicCreateView(generics.CreateAPIView): """ Should be available for unauthenticated users """ serializer_class = PublicThingSerializer def post(self, request, *args, **kwargs): return Response("It works!", 200) ... Yet for some reason this view returns 401 response for unauthenticated users. I tried a lot of things, the best I got was noticing that when I remove the REST_FRAMEWORK config from my settings.py completely, the response code changes to 403 forbidden. Any ideas? -

'No active account found with those credentials' when trying to log in with Django REST + Simple JWT
I'm trying to set up this API with user authentication but I keep getting the error message in the title when trying to log in. Registration seems to work and the super user can log in. I believe it is due to the password hashing, because when I go to the admin panel, every user has the same message: 'Invalid password format or unknown hashing algorithm.' except the super user (which I created in the terminal).

How to load the defualt value in combo box and how can add product to the cart without reloading the page in django?
Problem I want to the following things but am unable to understand that how can I do the following things. Firstly, I want that when the page is loaded the defualt values should be displayed from using the value from the combox. For example pack of 1KG is the defualt value so it's price and other values should be updated when the page is loaded. Secondly, I want that when the product is added to the cart the page is not reloaded or refreshed and a popup is shown that the product is added to the cart. CODE Script $(document).on("change", '.tranactionID', function (event) { event.preventDefault(); //get closest outer div.. var selector = $(this).closest(".productID") //find to get required elements.. selector.find('.id_price').text($(this).children(":selected").attr("price")); selector.find('.price-sale').text($(this).children(":selected").attr("sale_price")); selector.find('.id_discount').text($(this).children(":selected").attr("discount")); let id = $(this).find("option:selected").attr('transID'); let Url = `{% url 'cart:cart_add' 0 %}`.replace(0, id); selector.find("form").attr('action', Url); }); HTML {% regroup transaction by productID as ProductList %} {% for productID in ProductList %} <div class="col-sm-3 productID" > <div class="product"> <a href="{% url 'main:product-detail' productID.grouper.id %}" class="img-prod"><img class="img-fluid" src={{productID.grouper.product_image.url}} alt="" height="200px"> <span class="status id_discount">%</span> <div class="overlay"></div> </a> <div class="text py-3 pb-4 px-3 text-center"> <h3><a href="#">{{productID.grouper}}</a></h3> <div class="d-flex"> <div class="pricing"> <p class="price"><span class="mr-2 price-dc id_price">Rs. </span><span class="price-sale">Rs. </span></p> </div> </div> <select class="tranactionID" id="ItemID" … -
I cant access the files I upload with django inside the website with nginx when I try to download them
In my python Django project I can't figure out how to download .pdf files with nginx. In the site there will be constant uploads from an admin an the site shows the download links for this button in html and I direct to download with href.

Improving API Performance in DRF with select_related and prefetch_related
the below serializer and view which I am using to get data from multiple models is taking around 4 secs to get data.

How to properly kill MySQL/ MariaDB connections in Django using custom connectors
I am currently working on a project and I use the MariaDB connector to run the queries. I can't use ORM so I have to use raw queries. In general, the system works fine, as expected, but when I make a bit 'big' queries I get a Too many connections error message. This has happened to me for both MySQL and MariaDB connectors, but I mainly use MariaDB. Example of my code (truncated / simplified): import mariadb def get_cursor(): conn = mariadb.connect( user="user", password="pass", host="localhost", database="db") return conn, conn.cursor(named_tuple=True) def get_duplicated_variants(): results = [] conn_cursor = get_cursor() cursor = conn_cursor[1] conn = conn_cursor[0] try: cursor.execute("SELECT * FROM `db`.s_data;") columns = [column[0] for column in cursor.description] results = [] for row in cursor.fetchall(): results.append(dict(zip(columns, row))) cursor.close() conn.close() return results except mariadb.Error as e: print(f"Error: {e}") What I've tried: show status like '%onn%'; And also: show variables like 'max_connections'; So the max_used_connections = 152 and I have 2503 Connections. I also tried to execute the following query: SELECT CONCAT('KILL ', id, ';') FROM INFORMATION_SCHEMA.PROCESSLIST WHERE `User` = 'user' AND `Host` = 'localhost' AND `db` = 'db'; As seen in this question. But the number of connections is the same after running the … -
how to make a message model in Django where you can choose more than one person as the recipient
So, I'm trying to make a messaging model(between users) in Django admin where the sender can choose more than one recipient for the message. Models.py: class Message(models.Model): body = models.TextField(verbose_name=") sender = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete = models.CASCADE,editable=False) recipient = models.ManyToManyField(settings.AUTH_USER_MODEL) admin.py: class MessageAdmin(admin.ModelAdmin): def get_queryset(self, request): qs = super().get_queryset(request) if request.user.is_superuser: return qs sender_query = qs.filter(sender=request.user) recipient_query = qs.filter(recipient=request.user) return sender_query | recipient_query My current approach is the code above using a ManyToManyField. But this has created two bugs: The sender will see the same message more than once if more than one recipient are chosen, for example if the sender chooses three recipients, he will have three of the same message in his queryset The sender will not be able to open the message he has sent(if more than one recipient are chosen) because this error will get raised:get() returned more than one Message -- it returned 2!. of course the "2" can be any other number The thing I can't figure out Is that these bugs won't produce if the sender is superuser(And I assume that means there is a problem with my get_queryset code) What am I doing wrong in here? P.S: the reason of sender field being … -

How to set custom primary keys of different models as foreign key and migrate to mysql properly in django?
I created this model for my django project and connected it with mysql. I created customerid as the primary key in the Customer model and used it as a foreign key in the cart to represent the owner. There should not be an id field since django does not create one when primary key is true. Whenever I try to migrate the model, it errors "Cannot drop 'id': needed in a foreign key constraint 'api_cart_owner_id_c65befd7_fk_api_customer_id' of table 'api_cart'"). I tried fake migration but that created an unwanted id field in the mysql schema. And if I leave it like that and make a post request with a customerid I get this error "Incorrect integer value: '' for column 'owner_id' at row 1". I suppose that owner_id is looking for id field from customer model instead of customerid. I believe I have not set the cart model correctly. How do I represent the customerid and itemid (custom primary keys of different model) as a foreign key for the cart model and migrate it properly? class Item(models.Model): itemid = models.TextField(primary_key=True) name = models.TextField() price = models.FloatField() quantity = models.IntegerField() ordered = models.IntegerField(default=0) def __str__(self): return self.name class Customer(models.Model): customerid = models.TextField(primary_key=True) name … -

I'm trying to deploy a Django app in a Docker container. It works well but the first time I open a page I receive these messages: [CRITICAL] WORKER TIMEOUT [INFO] Worker exiting [INFO] Booting worker with pid: 19 The next time I open the same page it's pretty fast. Here's my Dockerfile (generated by wagtail app starter) FROM python:3.8.6-slim-buster RUN useradd wagtail EXPOSE 8000 ENV PYTHONUNBUFFERED=1 \ PORT=8000 RUN apt-get update --yes --quiet && apt-get install --yes --quiet --no-install-recommends \ build-essential \ libpq-dev \ libmariadbclient-dev \ libjpeg62-turbo-dev \ zlib1g-dev \ libwebp-dev \ nano \ vim \ && rm -rf /var/lib/apt/lists/* RUN pip install "gunicorn==20.0.4" COPY requirements.txt / RUN pip install -r /requirements.txt WORKDIR /app RUN chown wagtail:wagtail /app COPY --chown=wagtail:wagtail . .

How to copy a Django SQlite database to a Docker container?

How can I change the Dockerfile for that endeavor? -

Source specified in Javascript not showing up in Django template
Maybe this is a really dumb question, but I'm learning Javascript and Django and can't figure it out. I've spent a few hours on this and maybe it's a syntax error or something else. I want to specify the source of an image in javascript and then display the image in Django HTML template. It's not working, even with simple images Here is my javascript: $(document).ready(function() { var image = document.getElementById("image").src('https://res.cloudinary.com/.../{{ object.id}}'); } Here is my image info: <img src="#" id="image" class="mx-auto" width="250px" onerror='this.onerror = null; this.src="https://res.cloudinary.com/.../image.jpg"'/> What am I doing wrong? It's definitely not working - the image is not showing up even when it exists. I either get the default image or no image.
