Need to convert python dict in proto message format for gRPC

Question

I have a format like this and want to convert my python dict to this proto format proto code:

message template{

 message NicSettings{
    string network_adapter = 1;
    string network_name = 2;
 }

 message NetConfig{
    bool keep_mac_address =1;
    bool same_as_source = 2;
   repeated  NicSettings nic_settings = 3;
 }

 NetworkConfig network_config = 3;

}

python dict:

 template:
  { keepMacAddress: true, 
    sameAsSource : false, 
    nicSettings: [ {networkAdapter: "ethernet0", 
                    networkName: "Calpal1"
                    } ,
                    {networkAdapter: "ethernet1", 
                    networkName: "Calpal2"
                    } 
                 ] 
   }

How do I convert this to a proto message to pass it to gRPC.

It's not entirely clear that your .proto is correct (or are there typos in it?) but this looks like it should be something along the lines of

my_template_message = my_message_module_pb2.template( keep_mac_address=my_dictionary['keepMacAddress'], same_as_source=my_dictionary['sameAsSource'], nic_settings=tuple( my_message_module_pb2.template.NicSettings( network_adapter=my_subdictionary['networkAdapter'], network_name=my_subdictionary['networkName']) for my_subdictionary in my_dictionary['nicSettings'] ) ) . It's also a little odd in your .proto content that you've nested two message definitions inside another message definition - that doesn't look necessary at all.
