How can we send a Django User object and a list of users?

[Rajeev R]

Hello All,

I have two django applications and I want to send a user object from one django application to other django application through gRPC. I have seen string and integer types working fine. Please find the code attached.

service Usermanagement {
  rpc UserLogin (UserRequest) returns (UserResponse) {}
}

// The request message containing the user's name.
message UserRequest {
  string username = 1;
  string password = 2;
}

// The response message containing the greetings
message UserResponse {
  string message = 1;
  string fullname = 2;
  string token = 4;
  int32 status = 5;
}

This is my Django application code.

import grpc

from userservice import userservices_pb2
from userservice import userservices_pb2_grpc
from usermanagement.models import AppUser as User
from django.contrib.auth import authenticate
from rest_framework.authtoken.models import Token
from google.protobuf import any_pb2

class Usermanagement(userservices_pb2_grpc.UsermanagementServicer):

    def UserLogin(self, request, context):
        User = authenticate(username=request.username, password=request.password)
        if User is not None:
            (token, created) = Token.objects.get_or_create(user=User)
            User.authentication_token = token.key
            return userservices_pb2.UserResponse(message='success', status=0, fullname=User.fullname, token = token.key)
        else:
            return userservices_pb2.UserResponse(message='Incorrect Username/Password', status=1)

Please anyone can help me "How can I include the User object or user list" in the return response.

Actually I found the answer. https://developers.google.com/protocol-buffers/docs/proto3#nested

message UserResponse {
  string message = 1;
  string fullname = 2;
  string token = 4;
  int32 status = 5;
}

message UserListRequest {
   
}

message UserListResponse {
    message Result {
    string fullname = 1;
  }
  repeated Result results = 1;
}

in my django application code,

    def UserList(self, request, context):
        UserListRes = User.objects.all().values('fullname')
        return userservices_pb2.UserListResponse(results=UserListRes)

Hi. Please could you tell me how you got the grpc server to run with the django process?
