Django - Query on overridden save() method cached or something
I am overriding the default save() method of my model in Django 4. The problem is that I am making queries related to an instance of the model with the overridden save() method, but the queries seem not to be updated during the method execution. Example: class Routine(models.Model): exercises = models.ManyToManyField(Exercise) def save(self, *args, **kwargs): e = self.exercises.all() # 3 exercises returned super().save(*args, **kwargs) # I call to super deleting 1 exercise and adding a new one e = self.exercises.all() # same 3 exercises returned, not updated with the previous save() call Once all the code has been executed the routine.exercises have been properly updated, the problem is that I am not being able to get this query updated during the save() override. -

Celery error when a chord that starts a chain has an error in the group
I have a Chord. After the chord, we chain another task. If one of the tasks in that group of that chord raises an exception, I get a mess of an exception that looks like a bug in celery or django_celery_results.

In Wagtail, how to prevent page deletion by editors, or set a minimum number of pages of a kind
The site we developed has 2 type of pages, let's call them... "Static" ones: Home, Contact, About us, the general Catalog page, the general Blog page... "Dynamic" ones: each Collection in the catalog, each Blog entry. We, as developers, provide the final customer with all the structure for the Static ones, meaning they don't have to create them at all. There are many reasons for it but mainly because the site structure counts on these pages to always exist (in a Published state btw, but let's leave that aside). And we let and teach the client's editor to do, among other stuff.. Just edit the existing "static"pages. Create, edit and delete child pages in Catalogue and Blog. But we want to prevent them from deleting any of the other pages. Things might blow up, like, the Home shows some information collected from some of the other sections etc... but mainly because it doesn't make sense in our situation, that is: the only case in which they might delete one of the "static" pages is by accident. If they really want to delete any of these pages, that's a decision design that will involve other people (managers, designers and developers) and … -

Pycharm virtual environment only displays html of my project, no CSS
I've managed to set up a virtual environment in Pycharm in order to edit my Django app, and the associated website that it interacts with. The interpreter recognizes Django, and I can make edits to my app, but for some reason it can't seem to find my css files that are in my 'static_files' directory. Here are the instructions in my settings.py file, which Django should be able to access:STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static_files') Here are my directories in my project, maybe something is in the wrong place? I've tried adding STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static_files'),], and still nothing changes, can't find CSS. Not sure what to do about this, Pycharm seems to run into consistently run into problems that don't exist on my regular server for hosting my site and app. -
How to Create a Profile to an user
im relative new to django, before i only created simple applications that did not require any user stuff, now however i need to create a website with users, for now i created user register, log in and log out, but im struggling to create the profile for the user, should i create an app only for profile ? or maybe put the profile together on the models inside the user app where is the user authentication is, how do i go about the views on this matter ? if someone has a simple example that even a dumb person like me can understand i would appreciate a lot, thanks in advance.

Django - get model instance from a custom field
For a new project I defined a custom field EncryptedField. In this field, I use the methods get_prep_value and from_db_value. In these methods, I have access to the value of the field, so I can encrypt and decrypt it. I also need the value of another field of the model where EncryptedField is used for the encryption/decryption. So is it possible to have access to the instance of the model that calls my custom field EncryptedField. Like that I can have access to the other field value. Or there is an other way to get the other field value in these methods? I tried to use contribute_to_class but it seems to not be adapted to get the model instance. Thanks for your help -

Unable to create new objects of a model after referencing a field on another model as FK - django
I have overrided django auth model to a custom one, where I declare the USERNAME_FIELD as phone_number. OTPLog model is intended to keep a log record of the messages sent to the clients. To remove duplication of keeping phone numbers in db, I referenced the phone_number field in OTPLog to phone_number field in User as FK. class User(AbstractUser): phone_number = models.CharField( unique=True, max_length=11, validators=[RegexValidator(regex=consts.PHONE_REGEX_PATTERN)] ) USERNAME_FIELD = 'phone_number' class OTPLog(models.Model): created_at = models.DateTimeField(auto_now_add=True) expiry_date = models.DateTimeField(default=default_otp_duration) phone_number = models.ForeignKey(settings.AUTH_USER_MODEL, to_field='phone_number', on_delete=models.DO_NOTHING, db_index=True) Now making an object of OTPLog with phone_number is not possible any more, as the following exception is risen: otplog = OTPLog.objects.create(phone_number='01145279126') will give ValueError: Cannot assign "'01145279126'": "OTPLog.phone_number" must be a "User" instance. After making an object of User and calling otplog = OTPLog.objects.create(phone_number=user) the object is created successfully, but that is not the way I expect it work. I would simply need a FK constraint, where if a user with a given phone_number does not exist, the otplog object could not be created. How would I resolve the issue? -

Django Tailwind theme refresh - won't load
I have successfully installed [django tailwind][1] on my project. The problem is with the preview. As the installation guide advised, i tried 'python manage.py tailwind start', but the usual port http://127.0.0.1/ says: This site can’t be reached. If I start with my usual command of 'python manage.py runserver 127.0.0.1:8080', I can see the site and the new css, but it does not reload the page with reload-worker.js If I try to reload the browser with the button, it just goes into a spinning icon in the tab, never reloads and i have to restart the browser and also the server. So i can't really see the css changes, which is very annoying. What am i missing here? Reload listener seems to be working: HTTP GET /static/django-browser-reload/reload-listener.js 200 [0.01, 127.0.0.1:52032] HTTP GET /static/css/dist/styles.css 200 [0.01, 127.0.0.1:52031] HTTP GET /static/django-browser-reload/reload-worker.js 200 [0.00, 127.0.0.1:52031] -

Slice on the queryset argument of a Django Prefetch object and got "Cannot filter a query once a slice has been taken."
I did a slice on the queryset argument of a Django Prefetch object and got "Cannot filter a query once a slice has been taken." from django.db.models import Prefetch queryset = SomeModel.objects.filter(some_field=some_value).order_by('id')[:5] prefetch_obj = Prefetch('related_field', queryset=queryset) some_queryset.prefetch_related(prefetch_obj) Is there any way to slice only the first 5 query sets to be cached by prefetch?
