// Dispatch completes the `kataras/iris/mvc#Result` interface.

// If its ID is zero or less then it returns a 404 not found error
// else it returns its json representation,
// (just like the controller's functions do for custom types by default).
//
// Don't overdo it, the application's logic should not be here.
// It's just one more step of validation before the response,
// simple checks can be added here.
//
// It's just a showcase,
// imagine the potentials this feature gives when designing a bigger application.
//
// This is called where the return value from a controller's method functions
// is type of `Movie`.
// For example the `controllers/movie_controller.go#GetBy`.

// For those who wonder `iris.Context`(go 1.9 type alias feature) and
// `context.Context` is the same exact thing.
