Update Nested User Serializer With Image avatar
I want to add an avatar image to my profile serializer which is nested in the User Serializer as a one-to-one field. Im having issues getting the file to upload on the front end and I want to make sure I have everything correct in my backend Django DRF. I am using Djoser for the urls with DRF API. Please take a look and let me know if there is anything I might be missing.

How to update Celery tasks in production?
I have a Django application and some scheduled tasks handled by Celery. I use RabbitMQ as a message broker. Locally, everything works as supposed, but in production, celery worker runs old tasks that don't even exist anymore. I've tried adding worker restart to my celery worker Kubernetes-deployment -file, but that didn't make any difference. Here's what I tried: spec: containers: - name: celery-worker command: ["/bin/sh"] args: - -c - >- celery -A project_name -b 10.0.240.179 worker -l info && celery restart -A project_name -b 10.0.240.179 worker -l info This runs the worker pod without errors but it still uses the old, already deleted tasks. Is there a way how I could get updated tasks from Django's settings.py? -

django modeltranslation doesn't work with such queryset

How to loop through values in JSON and assign to another dictionary
I am developing a Python/Django web app. I am trying to parse JSON into a python dictionary, read the values in the dictionary, and assign the values to another dictionary if certain conditions are met. JSON is structured like this: {content: {cars: [0, 1, 2]}, other_stuff: []} Each car has multiple attributes: 0: {"make", "model", "power"...} Each attribute has three variables: make: {"value": "Toyota", "unit": "", "user_edited": "false"} I am trying to assign the values in the JSON to other dictionaries; car_0, car_1 and car_2. In this case the JSON response is otherwise identical considering each car, but the 'make' of the first car is changed to 'Nissan', and I'm trying to then change the make of the car_0 also to 'Nissan'. I'm parsing JSON in the following way: local_cars = [car_0, car_1, car_2] # Dictionaries which are already initialized. print(local_cars[0]['make']['value']) # Prints: Toyota (yes) print(local_cars[1]['make']['value']) # Prints: Toyota (yes) print(local_cars[2]['make']['value']) # Prints: Toyota (yes) counter = 0 if request.method == 'POST': payload = json.loads(request.body) if bool(payload): print(len(local_cars)) # Prints: 3 print(counter, payload['cars'][0]['make']['value']) # Prints: Nissan (yes) print(counter, payload['cars'][1]['make']['value']) # Prints: Toyota (yes) print(counter, payload['cars'][2]['make']['value']) # Prints: Toyota (yes) print(counter, local_cars[0]['make']['value']) # Prints: Toyota (yes) print(counter, local_cars[1]['make']['value']) # Prints: Toyota … -

Why Django modelform is submitted with enter key
I'm using Django modelform and it's submitted by pressing the enter key. This is what I wanted, but I don't know why it works. I didn't add any JS codes related to keydown but other codes to practice Ajax. Also, I found out that when there's only one input inside the form, it's submitted with the enter key, but my form has two inputs. What I'm doing is to add a comment on a post like instagram. I used Ajax to create a comment instance. models.py class Comment(models.Model): parent_post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name="comments") author = models.CharField(max_length=10) content = models.CharField(max_length=100) forms.py class CommentForm(ModelForm): class Meta: model = Comment exclude = ["parent_post"] HTML {% for post in posts %} <form method="POST" data-id="{{post.id}}" class="d-flex align-items-center w-100 mt-2"> {% load widget_tweaks %} <!-- this is a django package for easy CSS --> {% csrf_token %} {{ form.non_field_errors }} <div class="fieldWrapper"> {{ form.author.errors }} {{ form.author|add_class:"form__author"|attr:"placeholder:name" }} </div> <div class="fieldWrapper w-100"> {{ form.content.errors }} {{ form.content|add_class:"form__content"|attr:"placeholder:content" }} </div> <button class="btn btn-sm btn-warning w-auto">Write</button> </form> {% endfor %} JS (Here I didn't put the codes after getting JSON response from views.py) const forms = document.querySelectorAll("form"); forms.forEach((value) => { const post_id = Number(value.getAttribute("data-id")); value.addEventListener("submit", (e) => { … -
Django memory leak after network disconnected?
The question is Django 2.2 DRF 3.8.2 When the connection is disconnected after a REST request, the RAM is not cleared. That is, data from the database is unloaded and remains in RAM, somewhere deep in Django. How can such a problem be overcome ? -
Migrating Django TextChoices to IntegerChoices
In Django (3.2.8), I have a set of TextChoices, which I would like to change to IntegerChoices. I will keep the keys the same, just the values in the database stored will just differ. I do this for consistency and I'm fixing some legacy code. Naturally, I changed the TextChoices to IntegerChoices, and the corresponding field to an IntegerField. As expected however, upon migrating, I get a django.db.utils.DataError: invalid input syntax for type integer: "option1". I feel like there should be a way that I can define a mapping for this migration to happen, but wasn't able to find any documentation on this. -

Default storage delete method not working under windows [WinError 123]
I have the following issue. I wrote a unit test which works great under UNIX but breaks for Win10. I am uploading a file using Djangos default_storage: from django.core.files.storage import default_storage uploaded_file = SimpleUploadedFile(self.testfile_name, file.read(), content_type='multipart/form-data') response = self.client.post(url, {'file': uploaded_file}, *args, **kwargs)) testfile_new_path = response.data.get('file') ... default_storage.delete(testfile_new_path) When I want to remove the file after my test, I get an [WinError 123] error stating that the file doesn't exist. Actually this is true because testfile_new_path looks like this: C:\workspace\project\media\http:\testserver\media\path\to\my_file.txt Obviously, something is broken. I wonder how to do this properly. After all, I am using default Django methods. Thx!
