Can you put a context list inside a context in Django and cycle through it?
Currently, my project is taking grouped, query-sorted posts and displaying a for loop of each one. It is a hassle to put down every single for loop. I want to cycle through all the context without copy-and-pasting them in Jinja2. Can I do something like this? parent_context = { 'context': child_context } child_context = { 'object1': object1, 'object2': object2, ... } -

Django, JWT token refreshing: Paradox? or am I missing something?
Using this: https://github.com/Styria-Digital/django-rest-framework-jwt My app uses HttpOnly tokens for security. Let's say the token has 30 seconds of life with 90 minutes to renew -- using JWT_EXPIRATION_DELTA': timedelta(seconds=30) and JWT_REFRESH_EXPIRATION_DELTA': timedelta(minutes=90) So I send my /token-auth request with a user and password. I receive a token back good for 30 seconds. This is from the response header: Set-Cookie: my-token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6InJvbmVubWFnaWQrZmlsbXNpbnRsQGdtYWlsLmNvbSIsImlhdCI6MTU5ODQ3MzIyMiwiZXhwIjoxNTk4NDczMjUyLCJqdGkiOiI3YzEwZTJhMi0wZjQ0LTQ3NjAtOTg3MS0yMmNmNmM4MTI4ZTYiLCJ1c2VyX2lkIjoiNjEyODRjNDItYTdjOS00YWM1LWExZjYtMDY0YzNjOTI1OTVkIiwib3JpZ19pYXQiOjE1OTg0NzMyMjJ9.Y9DIw6ldGog-fsnMFph9ObmVQog1KWhTBjYxnM3u8N4; expires=Wed, 26 Aug 2020 20:20:52 GMT; HttpOnly; Max-Age=30; Path=/; SameSite=None; Secure So I keep sending subsequent requests during the 30 seconds of life, and getting good responses, , all is good. The request header reads: Cookie: my-token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6InJvbmVubWFnaWQrZmlsbXNpbnRsQGdtYWlsLmNvbSIsImlhdCI6MTU5ODQ3MzIyMiwiZXhwIjoxNTk4NDczMjUyLCJqdGkiOiI3YzEwZTJhMi0wZjQ0LTQ3NjAtOTg3MS0yMmNmNmM4MTI4ZTYiLCJ1c2VyX2lkIjoiNjEyODRjNDItYTdjOS00YWM1LWExZjYtMDY0YzNjOTI1OTVkIiwib3JpZ19pYXQiOjE1OTg0NzMyMjJ9.Y9DIw6ldGog-fsnMFph9ObmVQog1KWhTBjYxnM3u8N4 Now the 30 seconds expire.... the next request gets an understandable 401 but when I look at it's request header: The Token is gone, it's not used. It's been erased from Chrome. Given that --- how can I use /token-refresh when it requires the old token which has been erased? It's almost as if you are forced to renew it before it expires. But if this is the case, what's the point of having a longer JWT_REFRESH_EXPIRATION_DELTA if it cannot ever be used? -
Show Django Admin DateTimeField accordingly to User's timezone

I thought of creating custom Widget but in this case I would need to manually add it to each timestamp field, which doesn't sound right, especially, taking into considerations that I wanted to scale in future adding more models with timestamps. Is there any more pythonic solutions? Thanks! -

How to create a folder in Django to store user inputs
Goal of Code: User uploads a video to our django site. Use opencv to split it up into individual frames (this works well). We store the frames in a unique folder on our backend (this is where the problem lies). What we need help with: Creation of a unique folder based on user inputted video with django with correct path. Save the frames of the video into that folder.

This code works on my local computer path however we need to integrate it with django framework try: if not os.exists('exit_folder_path'): os.makedirs('exit_folder_path') except OSError: print ('Error: Creating directory') Here we use opencv to split the video into individual frames and then save them. The imwrite() function saves the frame as a jpeg in path defined by name parameter. We would … -
