How to remotely enter email credentials in django?
My web app is deployed by the computer team but developed by me. It is essential that the emails are sent using my team's email id. Hence, I am using a form to enter credentials into a safe file only accessible to my user. This is my settings file from config parser import ConfigParser EMAIL_CREDENTIAL_CONFIG = "credentials.ini" def credential(attr): config = ConfigParser() try: config.read(EMAIL_CREDENTIAL_CONFIG) return config["DEFAULT"][attr] except KeyError: pass EMAIL_HOST_USER = credential("EMAIL_HOST_USER") EMAIL_HOST_PASSWORD = credential("EMAIL_HOST_PASSWORD") The issue is that these values are loaded only when the server starts and I cannot remotely update it without using an ssh terminal and manually entering the file location. Can you suggest alternatives to either reload the email credentials automatically or to keep the creds safe from anyone having access to the server pc? -

How to avoid duplicate data in Django Template

Nginx redirect to Sphinx docs for Django app in Docker
I've added Sphinx documentation to a Django project, and want to serve the generated Sphinx pages from the /docs uri, but I can't seem to get my uris and directories aligned to serve the right stuff.

Update/merge data instead of replacing it with PUT method in Django Rest Framework
In a Django app (that uses DRF), I have a user profile model. To update the profile info, I want to use PUT. However, I have a field called "meta", that is an object/dict itself. If I am missing any of its properties (gender, mobile, birthday), I will lose that data since the whole "meta" is replaced with the new one. That does not happen with any of the fields (e.g., if I do not specify the first name, the field will just stay the same). Here's an example of a PUT request body: { "id": 1, "first_name": "Jane", "last_name": "Doe", "email": "jane@example.com", "meta": { "gender": "female", "mobile": 123456789, "birthday":"01-01-1970" } } What can I do to assure that the missing properties are not lost? Is there a way to implement or force a merge/update of the previous data with the one in the request? Here's the method: def put(self, request, pk): user = User.objects.get(id=pk) serializer = UserSerializer(user, data=request.data, context={'request': request}) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) And here's the serializer: class UserSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = [ 'id', 'url', 'first_name', 'last_name', 'email', 'meta' ] -
