Instance Method Details
#to_json(*a) ⇒ Object
Return a JSON string representing an array of all objects in this dataset. Takes the same options as the instance method, and passes them to every instance. Additionally, respects the following options:
- :array
-
An array of instances. If this is not provided, calls #all on the receiver to get the array.
- :root
-
If set to :collection, only wraps the collection in a root object. If set to :instance, only wraps the instances in a root object. If set to :both, wraps both the collection and instances in a root object. Unfortunately, for backwards compatibility, if this option is true and doesn’t match one of those symbols, it defaults to both. That may change in a future version, so for forwards compatibility, you should pick a specific symbol for your desired behavior.
