Question

I have a Place model and a PlacesController. Currently the controller responds to JSON with certain objects. I would like to add more fields to the responded objects. For example, I would like to add every place’s tags, queried by the method Place.tags.

I’m thinking in two solutions: convert the list of objects to a list of hashes and add the attributes that I want, or add a new column in the model, filling it in the controller iterating the list of objects. I’m not sure if there is a better way to do this.

Answer 1

I’m assuming:

 class Place < ActiveRecord:Base
   has_many :tags

If so, are you simply trying to add the associated tags to the place object’s json? If so, you can use (where ‘place’ is a Place object):

 place.to_json(:include=>:tags)
