as always, the documentation on the rails side is pretty bad. what you need to do is call either call to_json
with options or override the models to_json
method: http://apidock.com/rails/ActiveRecord/Serialization/to_json
activemodel return json with associated model data

in rails 4, I can not figure out how to fetch model and associated models together.
For example, I have a User model which has_many Message
The following code work properly.
@user = User.find 29, include: :messages
@messages = @user.messages
However, when I try to return @user with @messages in json
render :json @user
The returned result does not contain @messages, only the @user data is returned.
One workaround I can do is to construct a hash with
{user: @user, messages: @messages}
But the problem is messages are not nested or associated to user.
Is there a activemodel/activerecord buildin method to render associated data in a easier way?
