(Quick Reference) ## respond ### Purpose Attempts to return the most appropriate type for the requested content type (specified by either the `Accept` header or file extension) ### Examples
    // pick the best content type to respond with
    respond Book.get(1)

    // pick the best content type to respond with from the given formats
    respond Book.get(1), formats: ['xml', 'json']
### 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
--- | --- | ---
`respond Book.list()` | `java.util.List` | `bookList`
`respond Book.get(1)` | `example.Book` | `book`
`respond( [1,2] )` | `java.util.List` | `integerList`
`respond( [1,2] as Set )` | `java.util.Set` | `integerSet`
`respond( [1,2] as Integer[] )` | `Integer[]` | `integerArray`
Parameters: `object` - The object to render `arguments` - Named arguments. Supported `arguments`: `view` - The view to use in case of HTML rendering `model` - The model to use in case of HTML rendering `status` - The response status `formats` - A list of formats to respond with `includes` - Properties to include if rendering with the converters API `excludes` - Properties to exclude if rendering with the converters API
| 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.
