Is rolling out Django on WSL a valid option?
I am currently facing the challenge to rollout a Django/MySQL application on a windows computer without internet access. Though rolling out django on windows is possible, having a linux environment would be preferrable, since some mechanisms we would like to use do not run on windows. Sadly, a linux server is not an option for our customer. The question, that came to my mind now is: Would it be possible to host the django application on WSL? I have seen many topics about using wsl for django development. But i wonder if it would be a stable, secure and maintainable option for a django app in production. Do you have any experience with this setup? Are there any show stoppers I am missing? What would your recommendation be regarding django rollouts on windows? Thank you for your input. -
Set MYSQL date format from YYYY-MM-DD to DD/MM/YYYY - Django
I have a Django App with a MYSQL database and wanted to check is it possible to change the date format in MYSQL to accept dates input as DD-MM-YYYY rather than YYYY-MM-DD? I can change the date fine in Django but when I go to save my form data I currently get a date validation error stating that the date must be yyyy-mm-dd. (['“24/05/2022” value has an invalid date format. It must be in YYYY-MM-DD format.']) It works fine if I change the date to the format it wants YYYY-MM-DD but I would like the output to be DD-MM-YYYY. I read a few comment and suggestions saying to alter the settings.py file to allow different date formats (as below) but this did not seem to work either. # Date formats DATE_INPUT_FORMATS = ('%d/%m/%Y') # Internationalization # https://docs.djangoproject.com/en/3.1/topics/i18n/ LANGUAGE_CODE = 'en-AU' TIME_ZONE = 'Australia/Melbourne' USE_I18N = True USE_L10N = True USE_TZ = True Appreciate any help anyone can offer on this. -

Django queryset to show values every month
I'm making a Django APP (required) to calculate every month the profits and losses. There's a feature that I wanted to put that in N months you'll be paying the value/N (i.e: $100/5 that equals to $20 per month).

How to apply an arbitrary filter on a specific chained prefetch_related() within Django?
I'm trying to optimize the fired queries of an API. I have four models namely User, Content, Rating, and UserRating with some relations to each other. I'm going to the respective API to respond all of the existing contents alongside their rating count as well as a the score of given by a specific user to that. I used to do something like this: Content.objects.all() as a queryset but I realized that in the case of the huge amount of data tons of query will be fired. So I've done some efforts to optimize the fired querie using select_related and prefetch_related. However I'm dealing with an extra python searching that I hope remove that by a controlled prefetch_related() — applying a filter just for a specific prefetch in a nested prefetch and select. Here are my models: from django.db import models from django.conf import settings class Content(models.Model): title = models.CharField(max_length=50) class Rating(models.Model): count = models.PositiveBigIntegerField(default=0) content = models.OneToOneField(Content, on_delete=models.CASCADE) class UserRating(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, blank=True, null=True, on_delete=models.CASCADE ) score = models.PositiveSmallIntegerField() rating = models.ForeignKey( Rating, related_name="user_ratings", on_delete=models.CASCADE ) class Meta: unique_together = ["user", "rating"] Here's what I've done so far: contents = ( Content.objects.select_related("rating") .prefetch_related("rating__user_ratings") .prefetch_related("rating__user_ratings__user") ) for c … -
Why is only the first React component rendering in my multi-page in Django app?
I am trying to render a secondary component to a different URL in my React frontend of my Django app. The URLs seem to be set up correctly, as the page title is changing accordingly and no errors are thrown, but the page itself is blank.

How to use media files during deployment (django)?

How to properly catch fetch request in django

But they return to me information only about the first get request which is caused through urls.py. How do I get information that this was a fetch request and its Content-Type attribute.
