Re: How to access DataChannelMetaData from templates

Thanks for your help, I really appreciate this, now I can use the "comment" to pass additional metadata and use it at runtime.

 Hi,

If you really need to get access to model metadata at runtime, you
could get it by
configuring ServerRuntime like this:

ServerRuntime.builder().addModule(binder -> {
  binder.bind(DataChannelMetaData.class).to(DefaultDataChannelMetaData.class);
  binder.bind(HandlerFactory.class).to(ExtensionAwareHandlerFactory.class);
  ProjectModule.contributeExtensions(binder).add(InfoExtension.class);
})
...
You also need to add 'cayenne-project' dependency to your project.

After that, you can use DataChannelMetaData in your service at runtime:

  @Inject DataChannelMetaData metadata;

It could be tricky to get this in cgen's templates, as it's not that
configurable as server runtime.
We have a task for that [1], but no estimate though.
