I have a nested method that I'd like to output via to_json:
Venue has a method called published_events that returns events that are published:
def published_events
events_array = []
self.events.each do |event|
if event.published
events_array << event
end
end
events_array
end
Event has a to_param method on it that I'd like to include in the json rendering of Venue:
format.json { render :json => @venue.to_json(:methods => :published_events => {:include => :to_param}) }
This, of course, doesn't work to include the to_param method of events. Is there another way I should go about this or will I need to build my own json? Is there a way in the published_events method that I can include the to_param method?

We need to find some values from that nested collections of details. That collection is known as the JSON object and the information inside object are known as nested JSON object. Example 1: We create the nested JSON objects using JavaScript code.
Instead, we can use the tree structure of a JSON so that we can navigate to any node via a path. We have already covered parsing a simple JSON Object, Nested JSON Object and simple JSON Array as JsonNode previously.
A JSON array may be a collection of JSON objects or JSON arrays. Below is also a valid example of a JSON array. We need to use class ObjectMapper provided by Jackson API.
In the .net world, the go to library is Newtonsoft.Json, so we will be using that. For other methods of creating Json take a look here for an idea of how easy the Newtonsoft solution actually is.
@venue.to_json(:include => {:published_events => {:method => :to_param}})
