Django authencation problem- two different authencation one for custom admin and other for worker
I am facing this problem again n again. lemme explain you i am working on a complaint management site for my college, I have designed a separate customized admin panel which is working good, but the problem is occurring in making another admin panel for worker, where they can see allotted complaints and other things related to that, but I am not getting my desired result.

why does self.filefield_field.path of an instance of a django model does not match the path where the file was actually uploaded
I am building an app in django (Django==3.1.14). the app should allow the user to upload zip files (in particular, they are shapefiles). I want django to upload and manage these files by storing them inside a model, having a FileField t host the file. I want each file to be uploaded at a specific path, like this: MEDIA_ROOT/shp/<timestamp>/<file_name>.zip NOTE: timestamp has seconds precision. my model has a field shp_file_folder_path that must have value equal to the path of the folder in which <file_name>.zip is stored, so MEDIA_ROOT/shp/<timestamp> Now, I have written the following model def generate_current_timestamp(): return datetime.datetime.now().strftime("%Y%m%d%H%M%S") def generate_uploaded_shp_file_relpath(): UPLOADED_SHP_FILES_DIR = 'shp' uploaded_shp_files_relpath_from_media_root = UPLOADED_SHP_FILES_DIR timestamp = generate_current_timestamp() current_file_subfolder = timestamp # relative path of the folder which will contain the uploaded file uploaded_shp_file_relpath = os.path.join( uploaded_shp_files_relpath_from_media_root, current_file_subfolder ) return uploaded_shp_file_relpath # Create your models here. class Shp(models.Model): name = models.CharField(max_length=50) description = models.CharField(max_length=1000, blank=True) shp_file = models.FileField(upload_to=generate_uploaded_shp_file_relpath()) # this is a file, but in postgres is represented as path uploaded_date = models.DateField(default=datetime.date.today, blank=True) shp_file_folder_path = models.CharField(default='undefined', max_length=1000, blank=True) # this is to be not visible nor editable by admins # this defaultvalue is not required the function to be correct because it will be overwritten by the … -

API for dota player information using Django
Good afternoon, I might be mistaken as I am new to Django and API, but hopefully someone can correct me if I am wrong. I have this task to create a webpage here is the sample https://impactosolardota.com/. I have to create a website for something similar like this is Cuban leaderboard and I want to do one for Colombia. How can I obtain the player information that updates constantly. As far as my understanding goes, I need an API to send information from another website to mine. My plan is to build a Django website and the frontend in React. However, I am starting to think that I might not need Django at all and maybe do only with React?. -
Django Admin automatically logs me out when i click the save button and won't allow me log in again
Whenever I click the save button to add user on the django admin interface, it automatically logs me out and won't re-authenticate me despite being the superuser. The design pattern: I created a class called CustomUser which inherited the django AbstractUser and another class UserProfile model which has OneToOneField to the settings.AUTH_USER_MODEL(main.CustomUser) and added some common fields among the student, parent and staff(e.g other_name), then student, staff and parent class inherited the UserProfile and I added their specific field. So I do add a user first, then go to the student model to add the user as a student. main is my app_name. Kindly help with on this as I have deadline which is near. I'll provide more details and code on request settings.py file from pathlib import Path import os import secrets from django.conf.urls import handler403 # Build paths inside the project like this: BASE_DIR / 'subdir'.

I'm having problems with the layout of a web page using the django framework
I'm taking a course at ww3school and in part of the course I see that it didn't look the same in the proposed exercise, I'm going to put two images to reference my problemIn this image the page layout is correct, this image was my result I'm using Visual Studio Code on Windows 10 Django version: I've made sure I'm using the same version of Django as the course. I made sure the project settings (like settings.py) are correct. I checked that I followed the same customization steps. I tried clearing the browser cache or opening the page in an incognito/incognito window. -
How to make content fetched during login persist even if the user logs out and logs in again?
I currently am working on a project where a user authenticates, and when they are redirected to the home page, a GET request to an API is made: def home(request): url = f'https://icanhazdadjoke.com/' headers = { "Accept": "application/json" } #Putting the application/json in the header to get a JSON result r = requests.get(url,headers=headers) #Making a get request to get a random dad joke data = r.json() #Converting JSON data to a python dictionary required_joke = {'joke': data['joke']} return render(request,'test_section/Home.html',required_joke) Now, I mainly have two requirements: When the user presses the refresh button, a new joke should be generated (satisfied). If the user logs out, and logs back in again, the same joke that was being shown on the screen previously should be shown. For example, if the user logs out now, and logs back in, he should see this same joke displayed. I will be very grateful if someone can guide me regarding how to tackle this. It looks simple but I do not understand where to start. -
Updating a django table, hashing a specific field in a table
I have a table that looks something like class PodUsage(models.Model): pod_id = models.CharField(max_length=256, db_index=True) pod_name = models.CharField(max_length=256) start_time = models.DateTimeField(blank=True, null=True, default=timezone.now) end_time = models.DateTimeField(blank=True, null=True) anonymised = models.BooleanField(default=False) user = models.ForeignKey("accounts.ServiceUser", null=True, blank=True, on_delete=models.CASCADE) As part of our GDPR requirement, we need to anonymize data after a certain period, which I could absolutely do as a loop: count = 0 records = PodUsage.objects.filter( anonymised=False, start_time__lte=timezone.now() - timedelta(weeks=settings.DATA_ANONYMISING_PERIOD_WEEKS) ) for record in records: record.pod_name = hashlib.sha256(record.pod_name.encode('utf-8')).hexdigest() record.user = None record.anonymised = True record.save() count += 1 # Log count somewhere however I think I should be able to do it with an update function: count = PodUsage.objects.filter( anonymised=False, start_time__lte=timezone.now() - timedelta(weeks=settings.DATA_ANONYMISING_PERIOD_WEEKS) ).update( pod_name = hashlib.sha256(pod_name.encode('utf-8')).hexdigest(), user = None, anonymised = True ) # Log count somewhere ..... but I can't figure out the correct incantation to reference the field in the update portion as given, pod_name is not defined sha256("pod_name".encode('utf-8')) obviously just encodes the string "pod_name" sha256(F("pod_name").encode('utf-8')) breaks the code with 'F' object has no attribute 'encode' Any suggestions? -

creating custom validators for fields in Django REST framework serializers.Serializer
I am writing a serializer for a complicated put API with a large validate function. To simplify the logic and make it more readable, I want to create validators for individual fields (I want to make my serializer class as small as possible and hence don't want to write individual validate methods for each field). I am passing context to my serializer from the view and each of my fields share a common context. I want to use that context in the validator to perform the required checks. This is how I am attempting to create custom validators: My validator class: class MyCustomValidator: requires_context = True def __call__(self, value, serializer_field): context = serializer_field.context print(f"got this context: {context}") my serializer: class MySerializer(serializers.Serializer): my_field = serializers.IntegerField(required=True, validators=[MyCustomValidator()]) sending context in my view: def get_serializer_context(self): context = super().get_serializer_context() context.update({'test_context': {'key': 'value'}}) return context But when I am calling this API, I get the following error: __call__() missing 1 required positional argument: 'serializer_field' Can someone please tell me what am I missing here? Thank you... -
Trying to filter "managers" field to only show managers in the currently logged in user's department
I have 3 models The base User model that Django provides UserProfile, a model that has 2 fields: a foreignkey field with the user table a department field thats a choicefield with a dropdown, every user has 1 department And finally and Event model that contains a Manager field, a manytomany with the user model. I am trying to filter the manager field on the backend to only show managers that share the same department, since we don't want people to be able to add other departments as managers in their events This is the function that I'm trying to overwrite in my admin.py (using Django 5.0) def formfield_for_manytomany(self, db_field, request, **kwargs): if db_field.name == "managers": kwargs["queryset"] = Data.objects.filter(managers.userprofile.department == request.user.userprofile.department) return super().formfield_for_manytomany(db_field, request, **kwargs) I keep getting errors about the managers field not having a attribute of userprofile -
How serializer field can be set without showing it to enduser in DRF?
I have url like doc/<int:doc_id>/price/ for get and post and doc/<int:doc_id>/price/<int:id> for delete and patch or retrieve. My problem is, when creating a new price I want to set price.doc_id=self.kwargs['doc_id'] but at the same time I want that serializer field to be hidden in swagger documentation(I use drf-spectacular). The end-user should not be aware of that field. I know I can overwrite the create function of serializer and explicitly set the price or use serializers.save(doc=doc). But I ask this question to get a better solution. I tried hiddenfield as well but apparently it only takes default value and I do not know how to pass doc_id to it. class DocPriceOutHistorySerializer(ModelSerializerWithValidator): currency_name = serializers.CharField(read_only=True) type_price_name = serializers.CharField(read_only=True) class Meta: model = models.DictPriceList fields = ( 'id', 'dat', 'price', 'currency', 'currency_name', 'type_price', 'type_price_name', 'obj', 'doc', ) and in views.py data = request.data data['doc'] = self.kwargs['doc_id'] serializer = self.get_serializer(data=data) serializer.is_valid(raise_exception=True) self.perform_create(serializer) this will work but I do not want to manually write a request schema for swagger. -
how to use AsyncIOScheduler in django?

Creating a new thread in an API in django and calling another API in that thread
I was told that creating a thread for running background tasks will cause problems because in production gunicorn will kill a thread once the response is recieved. So, if I create a thread and inside that I call another api which is defined in the same app in django, will gunicorn create another thread for this api and thus wait for it to finish processing ? -
Huey process stuck, but why?
I'm trying to debug why our huey queue seems to freeze. We have a huey queu with 4 threads, however since a few days it seems to freeze. My hypotheses is that there is a method/task that keeps on running, and is stopping other tasks from processing. However it's a rather large project with a lot of stuff going into the queue. Huey settings: 'huey_class': 'huey.PriorityRedisHuey', 'name': 'queue', 'result_store': True, 'events': True, 'store_none': False, 'always_eager': False, 'store_errors': True, 'blocking': False, 'connection': { 'host': 'localhost', 'port': 6379, 'db': 0, 'connection_pool': None, 'read_timeout': 1, 'url': None, }, 'consumer': { 'workers': 4, 'worker_type': 'thread', 'initial_delay': 0.1, 'backoff': 1.15, 'max_delay': 10.0, 'utc': True, 'scheduler_interval': 1, 'periodic': True, 'check_worker_health': True, 'health_check_interval': 1, }, How can I debug this? Perhaps there is a setting that I can use to kill any task after x-time and log this somehow? Or perhaps something else I'm missing? Or perhaps there is a command to see what is currently being processed? -
How to Resolve Null Field Errors in Django When Creating a Task with Subtasks and Users
I'm encountering issues when trying to create a task with subtasks and users in my Django application. The task creation fails due to validation errors, specifically with the subtasks and users fields.

Django OperationalError: MySQL Connection not available
I'm encountering an issue with connecting Django to MySQL using mysql.connector.django. Here are the details: Error Message: OperationalError: (-1, 'MySQL Connection not available.', None) I'm setting up a Django project (WanderSight) with MySQL as the database backend. I've configured DATABASES in settings.py as follows: DATABASES = { 'default': { 'ENGINE': 'mysql.connector.django', 'NAME': 'seyedbe6_WanderSight', 'USER': 'seyedbe6_WanderSight', 'PASSWORD': '^uqQBK0*Fv59', 'HOST': 'localhost', 'PORT': '3306', } } Steps Taken: Verified MySQL server is running and accessible via command line (mysql -u seyedbe6_WanderSight -p). Installed mysql-connector-python in my virtual environment. Restarted Django development server (python manage.py runserver). Despite these steps, I'm still encountering the "MySQL Connection not available" error when running Django management commands like python manage.py createsuperuser. Django version: 4.1.10, MySQL version: Ver 14.14 Distrib 5.7.43, Python version: 3.9.16, I would appreciate any insights into what might be causing this issue or additional steps I could take to diagnose and resolve it -

Can Celery Be Used for Background Tasks Without Redis in Production?
I have an API that needs to upload large files to S3, with file sizes close to 10GB. I want to handle this as a background task and am considering using Celery. However, the client won't accept the additional cost of using a Redis service. Is it possible to implement this background task without using Redis? Any resources for this would be appreciated.
