Django and Subprocess: Development Server is Terminated on signal.SIGTERM
I am using subprocess.Popen in a Django application. I then store the pid in a database. The user can then send a rest request to /api/task/task.id/stop/ in order to kill the task.

I have a problem with nested self-referential objects. I have field responses which is children of this Message. It looks like tree but I'd like do this in one level. Is it possible in a simple way? How can I solve this? It's my serializer: class RecursiveField(serializers.Serializer): def to_representation(self, value): serializer = self.parent.parent.__class__(value, context=self.context) return serializer.data class MessageSerializer(serializers.ModelSerializer): message_id = serializers.SerializerMethodField() sender_user_id = serializers.SerializerMethodField() sender_user_fullname = serializers.SerializerMethodField() sender_user_email = serializers.SerializerMethodField() read = serializers.SerializerMethodField() attachments = serializers.SerializerMethodField() responses = RecursiveField(many=True) class Meta: model = Message fields = [ 'message_id', 'sender_user_id', 'sender_user_fullname', 'subject', 'body', 'created_at', 'read', 'read_at', 'attachments', 'responses' ] My present result looks like this: { "results": [ { "message_id": 115, "sender_user_id": 1, "sender_user_fullname": "user1", "subject": "Temat", "body": "<p>Wiadomość</p>", "created_at": "2019-09-28T19:33:40.846822Z", "read": true, "read_at": "2019-09-28T19:35:58.889000Z", "attachments": {}, "responses": [ { "message_id": 116, "sender_user_id": 1, "sender_user_fullname": "user1", "subject": "Re: Temat", "body": "<p>Odpowiedź</p>", "created_at": "2019-09-28T19:35:52.485656Z", "read": true, "read_at": "2019-09-28T19:36:21.932000Z", "attachments": {}, "responses": [ { "message_id": 117, "sender_user_id": 1, "sender_user_fullname": "user1", "subject": "Re: Re: Temat", "body": "<p>Odpowiedź do odpowiedzi</p>", "created_at": "2019-09-28T19:36:20.717966Z", "read": true, "read_at": "2019-09-28T19:36:20.714495Z", "attachments": {}, "responses": [], } ] } ] } ] } I'd like sth like this: { "results": [ { "message_id": 115, "sender_user_id": 1, "sender_user_fullname": "user1", "subject": "Temat", "body": …
