[INSTALLATION] - Django SynchronousOnlyOperation Error

[macmichael01]

Describe the error

I have a Django project that I am working on where I am trying to fetch TikTok user info using a class base view.

I am using gunicorn and Django is throwing an error: SynchronousOnlyOperation error. I added this bit of code to my gunicorn wsgi file os.environ.setdefault("DJANGO_ALLOW_ASYNC_UNSAFE", "true") which fixes the problem but seems like a bad idea.

The buggy code

def get_user_info(username):
    verify_fp = "code here"
    try:
        api = TikTokApi(custom_verify_fp=verify_fp)
        user = api.user(username=username)
        info = user.info_full()
        return info
    except Exception:
        return None

class TikTokAccount(APIView):

    def post(self, request, *args, **kwargs):
        ...
        info = get_user_info(username)
        ...

From what i can see from the error above. Since you're using WSGI which gunicorn is, then you have to use the django provided method after you have defined the function:

**_

from asgiref.sync import sync_to_async get_user_info = sync_to_async(_get_user_info, thread_sensitive=True)

_**

Else, all you need to do is to upgrade your website sandbox from WSGI to ASGI and make the relevant changes on your django project folder. If you find this helpful reachout on Upwork, my Profile name is Ayanlade Olawale, I saw your post on upwork
