Django: CSRF verification failed. Request aborted. in production without domain name
I am running a Django app behind Nginx in a Docker environment. My problem is sort of the same from this thread: Django returning "CSRF verification failed. Request aborted. " behind Nginx proxy locally. Upon learning that I have to add CSRF_TRUSTED_ORIGINS in settings, since I am using Django version 4.X, I added my localhost CSRF_TRUSTED_ORIGINS = [ 'http://localhost', 'http://localhost:3000', 'https://example.com', ] I can login to my admin when the container is deployed locally. However, when I deployed it to production, I still get the error: CSRF verification failed. Request aborted. I deployed it in a Google compute engine. The app does not have a domain name yet. Thus, I visit the app using its external address of the machine: http://XX.XX.XX.XX/admin. Should I add this address to my CSRF_TRUSTED_ORIGINS? My understanding is that this is the same as adding the localhost http://localhost since I am visiting the host machine's address. CSRF_TRUSTED_ORIGINS = [ 'http://localhost', 'http://localhost:3000', 'https://example.com', 'http://XX.XX.XX.XX' ] What if I deployed it to another machine with a different address? Should I again add it? Is there any other way to allow the CSRF without specifically adding the address since it would be tedious if I would be changing/migrating in … -

Disabling syntax highlighting in Python/Django Shell
With Django, you can start a Python shell in your project directory with python manage.py shell. Great, but can I disable that syntax highlighting somehow? Having every word colored some way makes it very hard to read anything. Removing termcolor.py as well commenting out every function of it fails, because django then can't import it and fails execution. The documentation sugggests that highlighting is not intended to be disabled. Is there no way to do this? -
Youtube API & Django integration
I have a function in Django that uses the youtube API to return the video_id, title and thumbnail_url based on the web_url that is provided by the user through the user create Video object form. The reason I did this was to make it easy for users to upload youtube videos to my app. def get_video_info(pk): print('get_video_info called') video = Video.objects.get(id=pk) web_url = video.web_url # Parse the video ID from the URL parsed_url = urlparse(web_url) query_params = parse_qs(parsed_url.query) video_id = query_params["v"][0] # Create a YouTube Data API client api_key = settings.YOUTUBE_API_KEY youtube = build('youtube', 'v3', developerKey=api_key) # Call the YouTube API to get the video details video_response = youtube.videos().list( part='id, snippet', id=video_id, maxResults=1 ).execute() # Extract the video details from the API response video_snippet = video_response['items'][0]['snippet'] thumbnail_url = video_snippet['thumbnails']['medium']['url'] title = video_snippet['title'] return { 'video_id': video_id, 'thumbnail_url': thumbnail_url, 'title': title, } I then have a signal function that triggers the get_video_info function when a Video object is created and then updates the Video fields with the return values of the function. @receiver(post_save, sender=Video) def create_video_info(sender, instance, created, **kwargs): print('create signal called') if created: # if the instance is being created video_id, thumbnail_url, title = get_video_info(instance.pk).values() instance.video_id = video_id instance.thumbnail_url = … -
How do I upload a local file to django-storages storage buckets?
I am trying to upload a file that is pre existing and has been modified on the server after upload, and then needs to be uploaded to the bucket.

Django set homepage at http://127.0.0.1:8000

Roles and Permissions between users and organizations
I'm building an application that allows users to belong to multiple organizations and can perform specific operations within each of these organizations as long as they have the required roles and permissions to do so. However, I kind of have issues implementing a satisfiable model that suits this requirement, especially given that roles and permissions in Django are typically related to the user's model and so it's impossible for them to vary with a particular user per organization. What I have done so far is implement a third model that records the role of a user with a particular organization in a separate table: class OrgUserPerms(models.Model): organization = models.ForeignKey(Organization, on_delete=models.CASCADE) user = models.ForeignKey("accounts.CustomUser", on_delete=models.CASCADE) user_role = models.CharField(max_length=25, choices=[ ("organization_admin","admin"), ("organization_manager", "manager"), ("organization_member", "member") ]) The problem with this model is that a user can have multiple OrgUserPerms referencing the same organization, I currently handle this by filtering the last saved OrgUserPerm object as the user's latest role in an organization then throw away the remaining OrgUserPerm objects with the same user&organization occurrence. I however feel this might eventually lead to operational bottlenecks in speed, security e.t.c and would deeply appreciate advice/suggestions from people with experience implementing something similar, thank you! -
