I am not a ruby person, but the project requires ruby. I have a 6 year old
piece of code I am attempting to update. I have recompiled the protobuf
files and protoc decodes a captured input stream correctly; however, the
code no longer works. I wrote a very simple ruby program to show the
issue. The issue is how do I reference the 2nd level of nested protobuf
messages that use proto2 syntax.
My simple code:
*input_stream = STDIN.readsvkmh = TelemetryStream.decode(input_stream)puts
"Device : #{svkmh.system_id}"svkmh_ent = svkmh.enterpriseputs "Level 1 :
#{svkmh_ent}"svkmh_jn = svkmh.enterprise.juniperNetworksputs "Level 2 :
#{svkmh_jn}"*
The output from it:
*Device : Q5Level 1 : <EnterpriseSensors: >../test.rb:17:in
`method_missing': undefined method `juniperNetworks' for
<EnterpriseSensors: >:EnterpriseSensors (NoMethodError) from
../test.rb:17:in `<main>'*
In the origin 6 year old code, this line worked:
*svkmh_jn = svkmh.enterprise.juniperNetworks*
And yet, protoc decodes it correctly:
*$ protoc --decode TelemetryStream telemetry_top.proto < ~/data.gpb | head
-25system_id: "poc-qfx5110-31"component_id: 65535sub_component_id:
0sensor_name: "jti_3_1:/system/:/system/:jsd"sequence_number:
27420timestamp: 1703006625404version_major: 1version_minor: 0enterprise {
[juniperNetworks] { 210 { 151 { 151 {*
