# Key Transforms
|
|
|
|
Key transforms modify the keys in serialized responses.
|
|
|
|
Provided key transforms:
|
|
|
|
- `:camel` - ExampleKey
|
|
- `:camel_lower` - exampleKey
|
|
- `:dashed` - example-key
|
|
- `:unaltered` - the original, unaltered key
|
|
- `nil` - use the adapter default
|
|
|
|
Key translation precedence is as follows:
|
|
|
|
##### SerializableResource option
|
|
|
|
`key_transform` is provided as an option via render.
|
|
|
|
```render json: posts, each_serializer: PostSerializer, key_transform: :camel_lower```
|
|
|
|
##### Configuration option
|
|
|
|
`key_transform` is set in `ActiveModelSerializers.config.key_transform`.
|
|
|
|
```ActiveModelSerializers.config.key_transform = :camel_lower```
|
|
|
|
##### Adapter default
|
|
|
|
Each adapter has a default key transform configured:
|
|
|
|
- `Json` - `:unaltered`
|
|
- `JsonApi` - `:dashed`
|
