Examples
Description
The respond method uses Content Negotiation to respond with the most appropriate content type. See the documentation on REST support for more information.
If a view is picked for rendering then a model will automatically be calculated to pass to the view.
The following table summarizes this convention:
| Example | Argument Type | Calculated Model Variable |

Due to the way Groovy works, while responding with a Map and arguments it is important to respond in this manner respond([:], status: 200) instead of this manner respond([:], [status: 200]). Failure to do so will result in the arguments being reversed.
