Django unittest - How to disable console logging only
I have a test in django (v2.2) that generates an error on purpose to check that errors are logged in the proper log files. But I get also a print in the console which is kind of annoying, I was looking for a way to hide the message. If I disable logging with logging.disable(logging.CRITICAL), it will not log the error in the files. I also tried to use with self.settings(LOGGING=logging) after removing the console handler from the loggers (see settings below) but it does not seem to be taken into account. Also, setting disable_existing_logger to False does not help. Do you have some ideas how to do that? my settings: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { 'msg_filter': { '()': MessageFilter, 'strings_to_be_ignored': [ 'Not Found: /favicon.ico' ], } }, 'formatters': { 'verbose': { 'format': '_____________________________________________________________' '\n%(asctime)s - [%(levelname)s|%(name)s] %(message)s\n' }, 'simple': { 'format': '%(asctime)s - [%(levelname)s|%(name)s] %(message).50s' }, }, 'handlers': { 'warning': { 'level': 'WARNING', 'class': 'logging.FileHandler', 'filename': '/some_folder/warning.log', 'formatter': 'verbose', 'filters': ['msg_filter'] }, 'warning_simple': { 'level': 'WARNING', 'class': 'logging.FileHandler', 'filename': '/some_folder/warning.log', 'formatter': 'simple', 'filters': ['msg_filter'] }, 'info': { 'level': 'INFO', 'class': 'logging.handlers.RotatingFileHandler', 'filename': '/some_folder/info.log', 'maxBytes': 1024 * 1024 * 2, 'backupCount': 9, 'formatter': 'simple', 'filters': ['msg_filter'] }, … -
Validate Post data when not using serializer?
I want to access post data directly in DRF (APIView example): def post(self, request, post_uuid, format=None): used_images = request.data['usedImages'] for image in used_images: print(image) return Response('') The used_images are a simple list containing only strings. I am a little hesitant to access the strings directly since it might be a security risk. Is there any way to validate/clean the strings so that they can be securely used to query the database? Thanks! -

Django DateTimeInput Type 'datetime-local' Not Saving To Database
I'm working on a django app to document trades. All the trade documentation is done on one page with an inline formset that shows all the entries and exits for a trade. All work well up to the datetimeinput field. If I remove the 'type' the form works great but is very non-user friendly. Working entries with no 'type' Non-working entries with 'type': 'datetime-local' So I guess you could say there are several issues datetime-local creates, or maybe it's not datetime-local to blame.

How to remove "unable to load configuration from home/user/project_name/file.py" in django website with PythonAnywhere

How does Django handle the incrementation of the AutoField Primary Key?
In a Django project with postgresql, I once inserted en entry in the db, and one day. Someone else who has access to it, has manually added 36 other rows in the db with pgadmin4. When I want to add new row with the Django project, I got IntegrityError obviously, because Django tries to add 1 to the last entry id added by the Django project (This is what I think it is trying to do). Here is the traceback: duplicate key value violates unique constraint "register_catalog_pkey" DETAIL: Key (id)=(2) already exists. How to tell Django that the last entry id is 36 (the last value manually added with pgadmin4)? I also tried to have the id field in Django Admin so I could edit it, but it did not show up. class RegisterAdmin(admin.ModelAdmin) list_display_links = ['id',] list_display = ('id',) Do I need to remove the primary key handled by Django, and define an IntegerField as primary key? register_id = models.AutoField(primary_key=True) to register_id = models.IntegerField(primary_key=True) -

Django Celery autodiscovery not discovering all apps
I'm using django cookiecutter for my project. When I try to run beat and worker I get this error. Received unregistered task of type 'test_post'. The message has been ignored and discarded. Did you remember to import the module containing this task? Or maybe you're using relative imports? Please see http://docs.celeryq.org/en/latest/internals/protocol.html for more information. I understood that this is due to celery not recognizing all tasks. In fact, if I run celery -A config.celery_app inspect report I get the following: include: ('myapp.users.tasks', 'celery.app.builtins') but the task I'm trying to run is inside myapp.core.tasks My INSTALLED_APPS: LOCAL_APPS = [ "myapp.core.apps.CoreConfig", "myapp.users.apps.UsersConfig", "myapp.dashboard.apps.DashboardConfig", ] I can't understand why it does only discover tasks from users app and not core.

Sharing with generated tokens and magic url in Django with DRF
I am building a file sharing application similar to dropbox with django and vuejs. It was easy to implement the sharing between users for folders but I am struggling to implement it by generating a unique link and access only to that folder. I have tried using django sesame package and it allows for creation of a tokenized url to access a user permitted page but still the folder permissions are managed by owner of them. I am planning to add a list field to a folder model and store generated tokens in that list so only the ones with a matching token in that list will be able to access to that folder. But I am not sure how to apply it. Any help would be appreciated. -

Django - save methode not working on overwrite
