Ensure Rack::MethodOverride

[ChanChar]

Similar to #926, Rails API mode doesn't include the middleware that converts POST to PUT calls leading to Routing Errors.

Possible solutions:

1. Create a custom controller and set the parent to that.
2. Generator checks for all required middleware and adds them to the application.

I don't think we can fix only our controller, middlewares are global to the application, right?

Maybe we could just change all the PUTs to be POSTs. We don't really pass in data, I don't think it even fits the semantics of HTTP.

true, i was thinking if there's a way to check for existing middleware within the app, the library could fast-fail.

That works too :)
