Why are my json attributes bouncing off in POST in Sinatra? - json

Question

I hope someone can share their knowledge with me. I have a small Sinatra app that I want to POST json data to it. The record is being created, thankfully, but none of the attributes make it. I've read several JSON examples using curl but they all yield the same result. So it makes me think it's my model. I can create records using tux fine so perhaps it's not my model.
curl command:
curl -XPOST -H "Content-Type: application/json"
"localhost:4567/date" -d
'{ "post": { "title": "different tile here"}}'
curl output:
=> {"id":13,"title":null,"body":null,"created_at":"2014-04-21T18:13:53Z",
"updated_at":"2014-04-21T18:13:53Z"}
sinatra output:

I've left off my layout files since I'm testing this POST via this rudimentary API. I've bounced around the few examples of Sinatra API's on the web and don't know what I'm not seeing. What am I overlooking here? It's almost like Strong Parameters in Rails 4, but if so why does tux allow me to create records? thanx, sam
