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.

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.

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")
