Specific model not visible for staff account in Django admin. Other models displaying as expected
I have several models in my project. All models are visible from the staff account if I add permissions for them, but one particular model is not displayed and I can't figure out why. This model is not displayed even if I add direct permissions to the user or add to a certain group with the necessary permissions, however, if I check the "Superuser status" box in the user settings, then this model appears. What could be the matter? -

My localhost:8000 just stopped to work. How can I get it back?
I am using ubuntu 20.04 I do not know if it matters, but I tried to see if the 8000 PORT was being used before I tried to run, and it was not. I was working on my Django project, running my localhost:8000 last night, but it stopped. Everything I have is a infinite loading. So, I returned today and I could not run my project. I do not know what happened. So, I started a new branch from the working code to check if it stopped because of me, but nothing changed. I've tried to restart and turn off my computer, I've erased my cache, I've tried in 4 different browsers (chrome, firefox, opera, brave), I've tried to re-run, and I've tried to use my local IP, but nothing happened. I am expecting to run again my project and I do not know if is related to my computer. -

DRF Api-Key missing Attribute

What is the difference between response.COOKIES and request.session to handle cookies in DJango?
Disclaimer: I am a beginner, following the Django for everybody course on Coursera and I've looked around for explanations on Google but I can't wrap my head around this. I'm confused; request.COOKIES.get('foo', 0) and response.set_cookie('foo', 'bar') seems to be a long way round of getting and setting cookies when one can simply do: request.session.get('foo', 0) or request.session['foo'] = 'bar'. It seems like a long way around because with the response.set_cookie method I need to start a HttpResponse but with request.session. It seems that if i stick to just request.session i don't need to switch inbetween request.COOKIES and starting HttpResponses to use response.set_cookie to handle cookies. Can someone please explain what is the difference between these approaches to handling cookies and when you would/should use one or the other? -

Logging in Python Django: INFO not logging onto file
I have setup a logger in my Django project for 4 different cases: info messages, debug messages, error messages, ad gunicorn logging.

Django save form with foreign key
I am currently trying to create a form where users get to fill in their details after creating an account.

Use a form in Django running locally to get folder/file path
Task: I am running a python Django web app locally. I would like to use an input form to get the path of a folder or file for use in further programming. Problem: I don't want to have users need to copy/paste the full path string; which is inconvenient, slow and clunky. The files are large and so I do not want to upload and store a copy. Is this possible given that the app is run on the same machine as the files? -
Django DRF Api Key Override Length expiry
I can see the following on the DRF page stating the key length can be overridden but being new at Django I really dont know how to use this? https://florimondmanca.github.io/djangorestframework-api-key/guide/#creating-and-managing-api-keys This package ships with a key generation algorithm based on Django's password hashing infrastructure (see also Security). The .key_generator attribute on BaseAPIKeyManager allows you to customize key generation. For example, you can customize the length of the prefix and secret key using: from rest_framework_api_key.models import BaseAPIKeyManager from rest_framework_api_key.crypto import KeyGenerator class OrganizationAPIKeyManager(BaseAPIKeyManager): key_generator = KeyGenerator(prefix_length=8, secret_key_length=32) # Default values class OrganizationAPIKey(AbstractAPIKey): objects = OrganizationAPIKeyManager() # ... I dont understand where this would go, how it would link to the admin view, or what comes after # ... Any help would be most appreciated -

Django - Filter on ManyToManyField
I have two models: class Student(models.Model): first_name = models.CharField() last_name = models.CharField() class Group(models.Model): name = models.CharField() students = models.ManyToManyField(Student) Some data (first_name and last_name concatenated): Group #1 | Blak Coleman Group #1 | Miguel Scott Group #2 | Jordan Barnes Group #2 | Jordan Gustman Group #2 | Jekson Barnes Group #3 | Jordan Smith As you can see theres three students by name Jordan.

ManyToMany field to same model without allowing the same object
I am using Django with a model that has a ManyToMany field to the same model. class Job(models.Model): name = models.CharField(_('Name'),max_length=80, blank=True, default="") related_jobs = models.ManyToManyField('self') this works fine. I can create Job objects and add jobs to related_jobs. The problem is that I can associate the same object to himself like this: job1 = Job.objects.create(name='Java') job2 = Job.objects.create(name='Python') job1.related_jobs.add(job2) job1.related_jobs.add(job1) #I don't want this to be possible Is there anyway to restrict this on the models? -
