DRF: Upload many similar files
I have created a user API for uploading documents. The link to the file is stored in license_* type fields, the document status is stored in license_*_status. models.py @deconstructible class User_directory_path(object): def __init__(self, prefix): self.prefix = prefix def __call__(self, instance, filename): return f'{instance.id}/{self.prefix}_{filename}' class Profile(models.Model): class DocumentStatus(models.TextChoices): NOT_UPLOADED = 'NOT_UPLOADED' ON_REVIEW = 'ON_REVIEW' ACCEPTED = 'ACCEPTED' id = models.CharField(primary_key=True, max_length=36, default=uuid.uuid4) license_0 = models.FileField(verbose_name='License(1)', storage=MinioBackend(bucket_name='django-backend-profiles-private', replace_existing=True), upload_to=User_directory_path('license_0'), max_length=255, null=True, blank=True) license_0_status = models.CharField(verbose_name='License(1) Status', max_length=15, choices=DocumentStatus.choices, default=DocumentStatus.NOT_UPLOADED) license_1 = models.FileField(verbose_name='License(2)', storage=MinioBackend(bucket_name='django-backend-profiles-private', replace_existing=True), upload_to=User_directory_path('license_1'), max_length=255, null=True, blank=True) license_1_status = models.CharField(verbose_name='License(2) Status', max_length=15, choices=DocumentStatus.choices, default=DocumentStatus.NOT_UPLOADED) license_2 = models.FileField(verbose_name='License(3)', storage=MinioBackend(bucket_name='django-backend-profiles-private', replace_existing=True), upload_to=User_directory_path('license_2'), max_length=255, null=True, blank=True) license_2_status = models.CharField(verbose_name='License(3) Status', max_length=15, choices=DocumentStatus.choices, default=DocumentStatus.NOT_UPLOADED) license_3 = models.FileField(verbose_name='License(4)', storage=MinioBackend(bucket_name='django-backend-profiles-private', replace_existing=True), upload_to=User_directory_path('license_3'), max_length=255, null=True, blank=True) license_3_status = models.CharField(verbose_name='License(4) Status', max_length=15, choices=DocumentStatus.choices, default=DocumentStatus.NOT_UPLOADED) license_4 = models.FileField(verbose_name='License(5)', storage=MinioBackend(bucket_name='django-backend-profiles-private', replace_existing=True), upload_to=User_directory_path('license_4'), max_length=255, null=True, blank=True) license_4_status = models.CharField(verbose_name='License(5) Status', max_length=15, choices=DocumentStatus.choices, default=DocumentStatus.NOT_UPLOADED) In this example, the user can submit 5 licenses. The field names are similar, only the postfix changes. Should I use this approach when uploading a large number of similar files? -

Django - models with relations to possibly nonexisting users
I am working on an enterprise LMS powered by Django REST framework. Authentication is done via Google OAuth 2.0 using the package drf-social-oauth2, and the target organizations for my software are schools and universities. Some models have foreign keys to the user model; however, due to the nature of my application, oftentimes a user may want to reference a user that isn’t present in the database yet. This happens because users are created in the database upon their first login in the application via OAuth, yet the person who wants to create a specific model instance referencing another user may want to do so before they’ve logged in for the first time: for example, a teacher may want to pre-enroll a list of students into their new course, but those users might not have logged in for the first time yet, and therefore might not exist in the database. I’ll give a concrete example with a model in my application: class UserCoursePrivilege(models.Model): """ Represents the administrative permissions a user has over a course. See logic.privileges.py for the available permissions. """ user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="privileged_courses", ) course = models.ForeignKey( Course, on_delete=models.CASCADE, related_name="privileged_users", ) allow_privileges = models.JSONField(default=list, blank=True) deny_privileges = … -
How to force link opening oustide of embedded browser / webview?
I setup a simple authentication system using python-social-auth-django. Everything is working fine on my computer and my mobile phone, but when I try to open login link from Messenger app with another phone (Huawei brand), the link opens inside Messenger's embedded browser and I get belows (same for Facebook and Google oauth). Searching around it has something to do with new policy disabling authentication from embedded browser such as Messenger embedded browser. What should I do either to force my login link to open outside of Messenger embedded browser or allow login with Facebook/Google oauth from WebViews browser ? You can't sign in from this screen because this app doesn't comply with Google's secure browsers policy. If this app has a website, you can open a web browser and try signing in from there. From my browser and own phone I open home link (from messenger app). This opens a browser window and login works fine. From another phone, when I click the messenger link, it opens in embedded browser. -

I have one table with a foreign key to another table? is it possible to populate the foreign key and another field from the same tabe?
I have a table properties_numBed, Each of our properties has a bedroom number assigned to it.

Are Django models "db_tablespace" equivalent to Postgres Schemas?
I just stumbled with the Django docs reference to db_tablespace option in Meta(), and I'm unsure: Are "tablespaces" (as defined in Django) somewhat equivalent to "schemas" (as defined and used in Postgres)? For example: Would the following models: from django.db import models class Person(models.Model): name = models.CharField(max_length=100) age = models.IntegerField() class Meta(): db_table = 'person' db_tablespace = 'people' class Book(models.Model): author = models.ForeignKey(Person) title = models.CharField(max_length=100) class Meta(): db_table = 'book' db_tablespace = 'books' ... be mapped to Postgres schemas / tables people.person and books.book? -

Django, Celery, and Celery beat via Copilot. Use Sidecars or multiple services?
I am able to easily deploy a Django application via Copilot. But now I need a Celery worker and beat. Sidecars sounds like what I want. Basically, define two new sidecars: one for a Celery worker and another for a Celery beat. But then I came across Developing an application based on multiple microservices using AWS Copilot and AWS Fargate. This takes the approach of deploying the other docker containers as their own services. It's not exactly clear to me which approach is best for my needs. Sidecars seems simpler and more straight forward. The only thing unclear to me on how to establish with it is the image (required) parameter. Why a URL? Why not a reference to the Dockerfile to build the worker and another one for the beat? -

Why is django-autocomplete-light single-select badly styled and broken when multi-select is working?
I have a screen in Django with a single-select autocomplete and multi-select autocomplete to the same model object (but different model fields). The multi-select is working perfectly, the single-select is functional, but poorly styled and also slightly broken (takes an extra click to get into the box to type). Help? EDIT: If I remove the multi-select box from the form, the single-select is still poorly styled and broken. So, while the multi-select shows something can work, it is likely otherwise unrelated.

cannot import name 'Categories' from partially inisialized module 'categories.models' (most likly due to a circular import)
I try to create 2 database categories and sous_categories in Django. in these 2 database a categories can have many sous_categories and sous_categories has only one categories. When i test my code i got the 'cannot import name 'Categories' from partially initialized module 'categories.models' (most likely due to a circular import)'. I think the error occurs to a circular dependency and the most solution i see int the web is: it can be resolved by moving the imported classes to a third file and importing them from this file. But i don't know how to do it with my code. here part of my categories model: class Categories(models.Model): nom_categorie = models.CharField(max_length=200) marchand = models.ManyToManyField(Marchands) sous_categorie = models.ManyToManyField(Sous_Categories) slug = models.SlugField(default='') images = models.TextField(blank=True, null=True) created_at = models.DateTimeField(auto_now=True) updated_at = models.DateTimeField(null=True)``` ` and my sous_categories model: ``from django.db import models from django.template.defaultfilters import slugify from categories.models import Categories class Sous_Categories(models.Model): nom_souscategorie = models.CharField(max_length=200) categorie = models.ForeignKey(Categories, on_delete=models.SET_NULL, null=True, blank=True) slug = models.SlugField(default='') images = models.TextField(blank=True, null=True) created_at = models.DateTimeField(auto_now=True) updated_at = models.DateTimeField(null=True)`` -
Django localhost default port already in use with postgres
I am receiving a error when running postgres, pgadmin and django. Port is already in use. I know how to use the sudo command to kill the server, however I am not being shown my databases in postgres. It just shows running when I start the server. When I create a new port database shows but doesn't migration the data. Also when I run migrations to django I get error, table already exist and or table doesn't exist. This happens everytime as if there is a duplicate database and it's not connected to the one showing in pgadmin. I tried dropping and deleting tables in pgadmin, and still get table exist. How do i fix this? How do I show all databases connected and delete the one that overrides my default port and have postgres show database servers in the app. Thank you in advance. Long post but I'm stressing and cant find a solution. Deleting tables in pgadmin, change port number, open postgres first than start pgadmin. -
Django save_m2m() in a separate, delayed transaction
I'm facing a vexing issue in which two adjacent lines of code seem to be committed separately to the database- with one of them hanging out for a full day or more before getting committed. if form.is_valid(): instance = form.save(commit=False) if form.cleaned_data['assigned_to_mtm'].count() <= 0: instance.status = "Unassigned" elif instance.status == 'Unassigned': instance.status = "Assigned" instance.save() form.save_m2m() With the above, I am finding the assigned_to_mtm reflected right away in the database. The status, however, isn't. Instead, when a separate save (even happening the next day) updates the status to something else, then this saved status comes in right afterward with the same timestamp, reverting its value to what it should have been at the time the mtm was saved. I'm astonished that I can't get these two to just happen in a single transaction (I tried the @transaction.non_atomic_requests decorator and doing it myself- that didn't help), let alone that the instance.save() hangs out uncommitted for so long, then gets committed only when the status is updated again separately. I might not even care, if the order of saves was at least preserved, but confoundingly, my earlier save is always committed after the next save. What am I doing wrong here? Can … -

djangochannelsrestframework problem with elastickbeanstalk and @model_observer
I have a consumers in which there is tracking of model changes using @model_observer. I subscribe to the event via @action and track its changes, everything works perfectly locally, the model has changed, I immediately received a change. But as soon as I try to put it on aws elastic beanstalk, I can subscribe/unsubscribe, but I don't get changes about events, although I see that the session is not broken. I thought that the problem was in queues or sessions, but I checked this together with technical support, they told me that everything was working correctly and the connection was made correctly. Maybe you know at least in which direction I should look and dig?

When I pass the payload to the post method, the points and de code fields are loaded but the shopper and card fields, which are both Foreing Keys, are not loaded and a null value is passed, as they are required fields I ended up getting an error. I did check, and the values for self.shopper.pk and self.card.pk are correct. MYCARDS_URL = reverse('mycards:mycards-list') def test_create_mycards(self): """Test creating a mycards""" payload = { 'shopper': self.shopper.pk, 'card': self.card.pk, 'points': 0, 'code': "code", } res = APIClient().post(MYCARDS_URL, payload) I did check to see if was something related to my serializer, but it is all good as you can see: class MycardsSerializer(serializers.ModelSerializer): """Serializer for cards.""" class Meta: model = MyCards fields = ['id', 'shopper', 'card', 'updated', 'created'] read_only_fields = ['id', 'created'] class MycardsDetailSerializer(MycardsSerializer): """Serializer for card detail view.""" class Meta(MycardsSerializer.Meta): fields = MycardsSerializer.Meta.fields + [ 'points', 'code'] Here is also my viewset which seems to be ok: class MycardsViewSet(viewsets.ModelViewSet): """View for manage card APIs.""" serializer_class = serializers.MycardsDetailSerializer queryset = MyCards.objects.all() authentication_classes = [TokenAuthentication] permission_classes = [IsAuthenticated] def … -
Django - can't delete rows when migrating backwards
I have a problem. I implemented a migration to create another option on my model (add the preview textchoice) and implemented a RunPython method to create rows on a table that matches my requirements. This works. The part that doesn't work is the reverse code. I simply query and filter the instances that I want to delete and try to delete them. In doing so, I get this weird error: Unapplying applications.0012_alter_mediatype_name...Traceback (most recent call last): File "/usr/local/lib/python3.10/runpy.py", line 196, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/local/lib/python3.10/runpy.py", line 86, in _run_code exec(code, run_globals) File "/root/.vscode-server/extensions/ms-python.python-2022.20.2/pythonFiles/lib/python/debugpy/adapter/../../debugpy/launcher/../../debugpy/__main__.py", line 39, in <module> cli.main() File "/root/.vscode-server/extensions/ms-python.python-2022.20.2/pythonFiles/lib/python/debugpy/adapter/../../debugpy/launcher/../../debugpy/../debugpy/server/cli.py", line 430, in main run() File "/root/.vscode-server/extensions/ms-python.python-2022.20.2/pythonFiles/lib/python/debugpy/adapter/../../debugpy/launcher/../../debugpy/../debugpy/server/cli.py", line 284, in run_file runpy.run_path(target, run_name="__main__") File "/root/.vscode-server/extensions/ms-python.python-2022.20.2/pythonFiles/lib/python/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_runpy.py", line 321, in run_path return _run_module_code(code, init_globals, run_name, File "/root/.vscode-server/extensions/ms-python.python-2022.20.2/pythonFiles/lib/python/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_runpy.py", line 135, in _run_module_code _run_code(code, mod_globals, init_globals, File "/root/.vscode-server/extensions/ms-python.python-2022.20.2/pythonFiles/lib/python/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_runpy.py", line 124, in _run_code exec(code, run_globals) File "/code/ews/manage.py", line 22, in <module> main() File "/code/ews/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/usr/local/lib/python3.10/site-packages/django/core/management/__init__.py", line 446, in execute_from_command_line utility.execute() File "/usr/local/lib/python3.10/site-packages/django/core/management/__init__.py", line 440, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/local/lib/python3.10/site-packages/django/core/management/base.py", line 414, in run_from_argv self.execute(*args, **cmd_options) File "/usr/local/lib/python3.10/site-packages/django/core/management/base.py", line 460, in execute output = self.handle(*args, **options) File "/usr/local/lib/python3.10/site-packages/django/core/management/base.py", line 98, in wrapped res = handle_func(*args, **kwargs) File …
