I think if we want to go down this path and support this we should add a from_dict static method to all of the user facing objects (i.e. Host.from_dict(...), Group.from_dict(...)).

Basically that from_dict method should mean that a_host == Host.from_dict(a_host.dict()) with one exception; groups should be excluded and post-processed or you might end up in the situation where groups don't exist before trying to create the reference.

Thoughts?

That makes sense. It may take me a little bit longer to get back on that particular update. I also need to check on what is going on with the tests that are failing here now after locally testing.

[dbarrosop]

Re failing tests, you may need to rebase as it's due to some breaking changes github actions did. Kirk fixed those already a few days ago though so hopefully you don't have to do anything about them.

I've still got this on my radar. I've just come down with a bit of a cold that has knocked me out of working much lately...

[dbarrosop]

No worries, get well!

[jvanderaa]

I'm getting this in front of me a bit more. I thought I had something but the tests are not working. So I am going to try to restart the process on another branch.

@jvanderaa What is the status of this?

Is this dead now i.e. should be closed?

[jvanderaa]

Yeah, probably good to close out. Sorry for leaving it for so long @ktbyers

[ktbyers]

@jvanderaa No worries at all.
