Module Sequel::Plugins::JsonSerializer::DatasetMethods
In: lib/sequel/plugins/json_serializer.rb

Methods

to_json  

Public Instance methods

to_json(*a)

Return a JSON string representing an array of all objects in this dataset. Takes the same options as the 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.
