Django makemirgations not updating database
When I make changes to models.py, I am expecting django to update the database structure for me when I run python3 manage.py makemigrations or python3 manage.py makemigrations appname. It doesn't detect any changes. I have had this issue once before and had to delete everything in the database to update it, which seems a bit drastic. What am I doing wrong?

Show different pages based on user - django
I'm building a web app IMDB's like. Each (logged) user views the same exact homepage, but they can flag/unflag every movie they want to save them in a "seen list". I've done that but I've noticed that every user logged can view the other user's flagged movies. Of course this is a problem, so I'd like to build a page relative to each user, so that everyone would have different "seen films" page based on the movies flagged as seen. The main idea behind this, is that whenever a user adds a movie to the database, he can flag it as seen with a simple models.BooleanField in the model of the film. I have then another model "Seen" where there are all the movies flagged. models.py class Films(models.Model): ... seen = models.BooleanField(default=False) class Seen(models.Model): ... views.py films = Films.objects.all() for film in films: flag = 0 seen_films = Seen.objects.all() for _ in seen_films: if film.name == _.name: flag = 1 break if not flag and film.seen: act_seen = Seen(image=film.image, name=film.name, description=film.description) act_seen.save() I need to add that for the user, I use the default class provided by django: from django.contrib.auth.models import User I get that the error is everyone can … -

I want the table to be visible only after the submit button clicks. But It's not staying on the screen as it is supposed to be.

Selenium authentication without sharing credentials
Isn't it bad to use actual credentials when testing log in pages with selenium webdriver? I am not very sure how security works but if someone is able to access the source code of the program together with its tests, then they would get a dummy test credentials that would still allow them to access the website. How do people go about this? -

How long class attributes live in python (Django)
I have this class in my Django app: class MyClass: property_1 = [] def add_elem(self): self.property_1.append(1) print(self.property_1) MyClass().add_elem() MyClass().add_elem() The output will be: [1] [1, 1] That means that when I start Django server, all the scripts(all app) are loaded to memory and as property_1 is a class attribute, every time I call add_elem(), I add a new '1' to the property? And property_1 will be cleaned only after restart server? -
Error H12 Heroku with Django bot scraping app
I have a bot made in Django and I want to run it on Heroku. The project's HTML template opens in Heroku just fine. This template has a form and a submit button. When I press the button, what is written in the form is sent to the main function of the bot and uses it during scraping. The problem is that the bot takes about 4 minutes to perform the functions and the Heroku router only executes requests for 30 seconds. I have searched for a thousand solutions on the internet but no matter how much I apply one after another I can't find it. I have also contacted Heroku support and they told me that I can use New Relic for long-runninf actions and use a background worker as well. I've tried setting both and I can't get around the H12 error either. Could someone tell me how to configure the worker and New Relic correctly? Many answers I find with this are old or I can't optimize it for my project. Thank you.

How to handle multiple lists with get_or_create in python?
At my Django application, I have a celery task that imports objects from an S3 Bucket. To make sure that I don't import objects twice, I use get_or_create, please also see the corosponding code: ... for key in keys: files_obj, created = Files.objects.get_or_create(file_path=key, defaults={'file_name': Path(key).name, 'libera_backend': resource_object}) if created: files_obj_uuids.append(files_obj.pk) resource_objects.append(resource_object.pk) if not files_obj_uuids and not resource_objects: print("No new objects found, everything already imported.") else: print(f'{len(files_obj_uuids)} new objects found. Importing now!') # Building-up task-group try: group([extract_descriptors.s(resource_object, key, files_obj_uuid) for (resource_object, key, files_obj_uuid) in zip(resource_objects, keys, files_obj_uuids)]).delay() return "Import jobs started" As you can see, I first fetch all objects (keys), then I check if the object already exists at the Database using get_or_create. If not I append files_obj and resource_object each to a seperate list. Later on I build a group task where I pass over resource_object, key and files_obj_uuid. At the extract_descriptors tasks I call with these parameters, the actuall error occours: django.db.utils.IntegrityError: (1062, "Duplicate entry 'some_uri/some_file_123' for key 'App_files_descriptor_080cec4f_uniq'") please also see the corosponding code: ... if json_isvalid: try: Files.objects.filter(pk=files_obj).update(descriptor=strip_descriptor_url_scheme(descriptor)) To get a better understanding please dont focus on the "descriptor" here.

I'm using django rq for some long running task, which I would like to provide some feedback about its progress. I hence created a function which is enqueued as a new task and set some model's attribute and save them. Here is a simplified view: class Status(models.Model): progress_a = models.PositiveIntegerField(default=0) class MyObject(models.Model): status = models.OneToOneField(Status) @django_rq.job('low-short') def set_status(self, progress_name, progress): setattr(self.status, progress_name, progress) self.status.save() def set_status_a(self, progress): self.set_status.delay(self=self, progress_name="progress_a", progress=progress) @django_rq.job('default') def long_running_job(): my_instance.set_status_a(100) Now, executing this give me the following output : 2022-05-16 15:50:03 app-85c8459c79-mrkhg rq.worker[1] INFO low-short: api.models.MyObject.set_status(progress=0, progress_name='progress_a', self=<MyObject: MyObject object (129)>) (c13480ca-a25b-4463-af9a-a0a0dd67de61) 2022-05-16 15:50:03 app-85c8459c79-mrkhg root[41] WARNING Import error for 'api.models.MyObject' Traceback (most recent call last): File "/usr/local/lib/python3.9/site-packages/rq/utils.py", line 141, in import_attribute module = importlib.import_module(module_name) File "/usr/local/lib/python3.9/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1030, in _gcd_import File "<frozen importlib._bootstrap>", line 1007, in _find_and_load File "<frozen importlib._bootstrap>", line 981, in _find_and_load_unlocked ModuleNotFoundError: No module named 'api.models.MyObject'; 'api.models' is not a package api is a package api.models a module models.MyObject a class. I don't get why it doesn't work. What am I doing wrong ? long_running_job starts as a job flawlessly. Note: when removing self=self, it complains about missing self.
