I have the following associations in my ActiveRecord models 1) Groups 2) Users Each Group has and belongs to many users There is an api endpoint - <Site>/api/v1/groups which returns a list of the groups. In the controller when I am sending a list of 20 groups, the Users property is not populated beforehand in the json structure. Anyway to include the Users property in the json response.
