How to get JSON body as a params in action?

[nilcolor]

I've create really simple Lotus app (https://gist.github.com/nilcolor/21ead88d1517e824f103). And I'd like to receive JSON data (via POST's body). But... controller receives request, responds with OK but params are empty... (not really empty - it's full Rack params hash but without data I need).
If params are posted in URL - they are readable via params arg. Even if action is accept :json btw

Some things appeared when @brennovich and I were investings this.

Probably @nilcolor didn't configure the body_parsers of his app. If he configure the body_parsers for json the params passed to the action will start to be available.

But some things aren't clear, and maybe @joneslee85 can help us to figure them out.

• The purpose of body_parsers configuration is: Define different parsers that will be used when a request is received on specific MIME types
• The purpose of accept is: block requests that aren't on the defined MIME types

Are this assumptions right?

ps: accept is currently not doing what it should, because if we configure a controller to accept only json requests, it doesn't return status code 406 for requests with different content-types

Yep, as @carloslopes said @nilcolor, please make sure to uncomment this option in your application.rb:

Once you get this done you'll start to get your params :)
