Python, Django: django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'accounts.Usuarios' that has not been installed
Good morning! Although questions similar to this have been posted here, I have not been able to resolve my issue yet. I have tried all proposed solutions. The problem started after I put, or at least tried to put, "email" as the username, removing the username from the model. I will share the points that I think are relevant. If you need more, you can ask. problem: PS C:\SocialFacil\socialfacil_web> python manage.py runserver Watching for file changes with StatReloader Exception in thread django-main-thread: Traceback (most recent call last): File "C:\SocialFacil\lib\site-packages\django\apps\config.py", line 235, in get_model return self.models[model_name.lower()] KeyError: 'usuarios' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\SocialFacil\lib\site-packages\django\contrib\auth\__init__.py", line 170, in get_user_model return django_apps.get_model(settings.AUTH_USER_MODEL, require_ready=False) File "C:\SocialFacil\lib\site-packages\django\apps\registry.py", line 213, in get_model return app_config.get_model(model_name, require_ready=require_ready) File "C:\SocialFacil\lib\site-packages\django\apps\config.py", line 237, in get_model raise LookupError( LookupError: App 'accounts' doesn't have a 'Usuarios' model.

Is it possible to save a class using django redis cache to use it after the user reconnects
I need to save a class to use it if the websocket disconnects and assign it to the websocket again if it reconnects. But when saving i get this error: "Exception inside application: Can't pickle local object" which i think is because i cant save a class to the cache. Is it possible to overcome this and save the class in the cache? -
How can I give input with getpass to a Django app when deploying using Nginx, Gunicorn and systemd?
I have a Django app that has key on disk which is encrypted using AES Cypher, and must be unencrypted in memory for use during the processes.

Django threaded comments (MPTT) optimization issue
I'm using MPTT model to build a nested comments system in my Django Rest project. Everything works so far but I experience a huge performance issue when querying a database for API response. The schema of comments layout: Root Comment / \ Comment Comment / \ Child Child Whenever I'm querying all comments as an array in API response recursively: { "comments": [ { "id": 1, "children": [ "id": 4, "children": [ "id": 5, "children": ... ] ] } In this case even with "prefetch_related" and "select_related" I'm getting over 50 queries for 2 parent(root) comments (which have children comments and so on). Is there an efficient way to optimize this query? Even 2 levels comments system is acceptable for me but I can't figure out the right implementation for this: Comment \ Child1, Child2, Child3, Child4 My code for reference: class Comment(MPTTModel): profile = models.ForeignKey(Profile, related_name="comments", on_delete=CASCADE) post = models.ForeignKey(Post, related_name="comments", on_delete=CASCADE) parent = TreeForeignKey("self", related_name="children", null=True, on_delete=models.CASCADE) text = models.TextField(max_length=350) date_published = models.DateTimeField(auto_now_add=True, verbose_name="Date published") comments = Comment.objects.filter(level=0) \ .select_related("profile", "post", "profile__specialization") \ .prefetch_related("children", "parent") \ .order_by("-date_published") -

Why i can't use migrations with user_account in my INTERNAL APPS
When creating a custom model, when I register the app in INTERNAL APPS, the program doesn't allow me to perform migrations and throws an error: "ModuleNotFoundError: No module named 'user_account'." (Python Django). I have tried cleaning the database as we did in the class and recreating it, but with the 'user_account' line in INTERNAL APPS, it refuses to perform the migration, and without it, it says that 'user_account' is uninstalled. -
What options are available for performance tuning a soundx query?
I was recently asked about improving website performance for a peers website. What options are typically used for performance tuning sites enabled with Soundx? Overview Using the homophones Smith/Smythe, I was able to reproduce the behavior of the website query response time described. These are measured at the browser so there's a lot that could go into the number, but generally speaking the values were what we would expect, less for the non-Soundex search and more for Soundex search. Smith - Not Soundex - (1705 results) - 6.62s server wait Smythe - Not Soundex - (8 results). - 5.51s server wait Smith - Soundex - (4446 results) - 9.47s server wait Smythe - Soundex - (4446 results) - 10.85s server wait Technical Stack language - python - 2.7.5 framework - Django - 1.3 database - not yet known - not yet known NOTE: Database type and version will most likely play a role in what solutions are viable.

join() argument must be str, bytes, or os.PathLike object, not 'NoneType' with Django
I'm running into an issue on my Django app. The issue is when I click on Add a Record the app returns the error: join() argument must be str, bytes, or os.PathLike object, not 'NoneType' but it shouldn't since I'm not doing any joining in my code. The view for this is: def add_job_record(request): add_form = AddJobTrackerForm(request.POST or None) if request.user.is_authenticated: if request.method == "POST": if add_form.is_valid(): add_job_record = add_form.save() messages.success(request, 'Job Tracker added') return redirect('core:home') return render(request, 'applications/add_record.html', {'add_form': add_form}) else: messages.danger(request, "You must be logged in") return redirect('core:home') I found a post here (I forgot to save the link) where the answer was to remove {'add_form': add_form} from my code but the form doesn't show up on the page when I removed it -

Why is Invoke task reexecuted on code change?
I have defined Invoke task that runs foo function and then starts my Django app. Whenever I change the code, the whole task is reexecuted. I don't understand why reload mechanism triggers the task. I want foo function to be called only on docker-compose up. Can somebody explain? Setup: docker-compose.yml: version: '3' services: backend: entrypoint: ["invoke", "my_task"] volumes: - .:/code tasks.py: from invoke import task import os import django os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.settings") django.setup() @task def my_task(context): foo() management.call_command("runserver", "0.0.0.0:8000") -

How to change user password from Cognito Forgot Password using Lambda and triggers?
I'm building an SSO process to integrate an app with Cognito. For that I'm using Django (the app), Mozilla OIDC (for integration with Cognito) and AWS Cognito. I'm able to migrate users from the already existing app to Cognito User Pool. I need to contemplate the situation where a user clicks on "Forgot Password", which should trigger a Lambda, and allows me to update the user's password (hashing it) into the Database by writing the lambda_handler code. Now I don't understand how to achieve this. More specifically, the flow and which trigger to use. So far, when a user clicks on Forgot Password, it sends an email with a confirmation code, which the user has to enter along with the new password and new password confirmation.

This image gets pulled up when the lambda gets triggered (I think there are generic triggers …
