Display media files with Django
I learn Django and I have a problem with display img in settings I add: MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "moje_media") and in url.py I add static urlpatterns = [ //routing ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Problem is that img is uploading correctly but I have a problem with display that. For example - in my template I have img tag: <img src="{{MEDIA_URL}}{{film.plakat}}"> But it doesn't display that. I inspect img that and src contain "/media/plakaty/test.jpg". I go to Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: admin/ filmy/ login/ [name='login'] logout/ [name='logout'] ^media/(?P<path>.*)$ The current path, media/plakaty/test.jpg, matched the last one.

A better solution for the increasing number game?
I am remaking the question I made here based on the feedback given to me. If there is still something unclear in my question please let me know. Explanation for the game: Increasing number game where the user has to guess before the number is going to stop increasing. This is purely a random chance and is done by clicking on a button by the user. Number is calculated on the server side after each game. Number will be increasing by 0.01 starting from 1.00 until the number calculated on the server side. Solution I have come up with: Running a background process using apischeduler. Executing the number increasing function every 0.1 seconds which adds 0.01 to the current state of number and sends the state result to frontend using Django Channels. I am pulling and updating the state using database queries. When the end result (number) is reached, new number will be calculated and there will be a timer running before new game begins. That all this seems odd considering I am calling a function in the background every 0.1 seconds forever. I can not figure out how to complete the task differently though. Is there a better solution/more … -
How to set allowed characters in Django forms?

Should I use .values_list(), .exists() or something else to check for existence?
I have a model with a string as primary key class Player(models.Model): player_tag = models.CharField(max_length=9, primary_key=True) [...] The player tag is unique to each player, and I retrieve batches of up to 30 player tags before either creating or updating them. However doing so requires me to check if the player tag already exists, and for that I know Django has .exists() method, that checks for the presence of an item inside a queryset. However I figured that would hit the database each time I looked for a player, which sounds less than ideal. I also thought about using a line like this : player_ids = models.Player.objects.values_list('player_tag', flat=True) Which would hit the db once and then I'd check against this list for presence. But I doubt this scales. (The player list can get very lengthy) Is there a better solution for this, something that would allow me to check for the existence of a string primary key while keeping the impact on the database minimal ? -

Django Storages (GCP) returns NULL if the app is deployed in Cloud Run
I am using Django Storages to upload images on GCP's cloud storage bucket and I accomplished this on localhost by following these steps - Created a private bucket on Cloud Storage. Created a service account with Storage Admin privileges and also generated a JSON key. Installed Django Storages for GCP and Pillow. Created relevant environment variables like GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT and GS_BUCKET_NAME. Wrote a POST & GET request and it works like a charm on local machine. However, when I deployed this on Cloud Run I am able to upload the images but I get NULL instead of the image's Authenticated URL in response while fetching the image via GET request. As, Cloud Run uses Compute Engine Default Service account So I decided to give it a Cloud Storage Admin permission and then I tried again but still no luck. How can I make this work? -
