How to Secure Django Media Files in Production
In my localhost server, I was able to restrict users from accessing pdf media files which they are not supposed to access given that they are not the uploader of the file or the admin of the system. The problem is that when I tried to deploy my application, the restriction on my media files no longer works. This is my urls.py urlpatterns = [ path('media/pdf/<str:path>', views.pdf, name='pdf'), ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root= settings.MEDIA_ROOT) And my MEDIA_URL and MEDIA_ROOT in settings.py: MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') Also my debug is still set to TRUE in deployment, could this also be the problem? -
can Django listen to html events like javascript?
I have a html page with a datalist like this <input list="areas" placeholder="type option here"> <datalist id="areas"> <option>TV</option> <option>LAPTOP</option> <option>PHONE</option> </datalist> My objective is to create another list of selectable options using the information the user selected on this one, for example, if he chooses TV I'd like to either a) send a request to django and get the JsonResponse and render the next datalist using that Json. b) send a request to django and get the JsonResponse and make it return another page just like the previous but with the next data I learned that when Django renders and HTML page, I can send a context python Dict, so html has access to those variables. However, I am struggling to make the HTML call Django view functions and either render their result on the same page or open a new page with those results. I heard that HTML has some events that can be "listened" (don't know how that works) and the listener can make things happen, Javascript seems to be built exactly for this purpose since so many intuitive funtions like (onclick("makeSomething") / onchange("makeSomething")/ onhover("makeSomething")) Can I do something like this using only Django and HTML ? -

Django throws AttributeError: 'str' object has no attribute '_meta' when trying to migrate
I'm working on a small project on my own, and I have some problems with the migrations. I managed to migrate everything well so far, but I removed a field from my models.py and now there are problems somehow. I had a field called tags that was referencing to a model from taggit, but I decided to remove this field and do it on my own, so the field tags still exists but its not referencing to the tagablemanager of taggit anymore, but on my own tag model now Nevermind everytime I excecute python manage.py migrate to make the database, this error is thrown: Applying inventory_app.0014_item_tags...Traceback (most recent call last): File "/Users/ilianhaesler/Documents/Work/inventory/inventory/manage.py", line 22, in <module> main() File "/Users/ilianhaesler/Documents/Work/inventory/inventory/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/core/management/__init__.py", line 419, in execute_from_command_line utility.execute() File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/core/management/__init__.py", line 413, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/core/management/base.py", line 354, in run_from_argv self.execute(*args, **cmd_options) File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/core/management/base.py", line 398, in execute output = self.handle(*args, **options) File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/core/management/base.py", line 89, in wrapped res = handle_func(*args, **kwargs) File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/core/management/commands/migrate.py", line 244, in handle post_migrate_state = executor.migrate( File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/db/migrations/executor.py", line 117, in migrate state = self._migrate_all_forwards(state, plan, full_plan, fake=fake, fake_initial=fake_initial) File "/Users/ilianhaesler/Documents/Work/inventory/inventory-env/lib/python3.10/site-packages/django/db/migrations/executor.py", line 147, in _migrate_all_forwards state = self.apply_migration(state, migration, fake=fake, fake_initial=fake_initial) … -
Union of non-model serializers in Django Rest Framework
Through serializers, I'm trying to describe that a field could be serialized as one of N options (similar to typing.Union). The goal of this is to use DRF Spectacular to generate Union Types. For example: From the following serializers class SerializerA(serializers.BaseSerializer): a_field = serializers.CharField() class SerializerB(serializers.BaseSerializer): b_field = serializers.CharField() I want to describe: class CombinedSerializer(serializers.BaseSerializer): combined_field = <either_serializerA_or_serializerB> Which, through DRF spectacular, I would be able to generate into export interface SerializerA = { a_field: string; } export interface SerializerB = { b_field: string; } export interface CombinedSerializer = { combined_field: SerializerA | SerializerB } I've looked into https://github.com/denisorehovsky/django-rest-polymorphic but that seems to support model serializers. https://github.com/tfranzel/drf-spectacular/issues/382 also doesn't seem to support this use case - any suggestions? -

How to share memory using gunicorn+uvicorn workers or Daphne+supervisor
I have a Django web application that uses Daphne web server. I have a problem when running multiple instances of app using supervisor (that corresponds to running app with multiple uvicorn workers using gunicorn). I tried to solve it by sharing memory using Redis DB to save user instances so that every worker can access logged in users but then I came across the problem. There is threading inside of User class and I can't pickle _thread.lock object so I can't use Redis. If I separate threading from my User class, I don't profit from it at all because then worker has to do same job again, that is, make a thread, when I send request. Is there a workaround to this problem? I.e. using internal shared memory or something like that? -

Django doesn't save ManyToManyField field. Why?
I have been searching for the answer everywhere but haven't managed to find it. Django doesn't save a ManyToManyField (Categories). Please let me know why if you know. So, it saves everything except the Category - ManyToManyField. Everything other works well. There is no any errors.

Django Rest Framework - What to return from a custom filter function for Django Rest Multiple Models

the checking out doesnt work properly , the error is always != 0 but it cannot be so
the idea is that while checking out, if you dont fill in the info, you will get stuck there until you fill in all the info and then you can continue I suppose that the problem is that the error is constantly != 0.

Safely remove a field from django model

I don't want to delete all the migration files, since they are in the git and it's not my project.
