[@action Django restframework ]: execute commands when a new client is registered

Question

good night. I am developing a customer registration API, and I would like it that every time a new client is registered, runs something, and I tested a code and it didn’t work. someone can help me?

```
from rest_framework.decorators import action
import requests

@action(methods=['post'], detail=True)
def update_status(self, request):
    if(request.method == 'POST'):
        ## do something
```
