Include nested json in Rails

Question

I added an object nested in another object using the model. Just like this:

Ingresso model ->

def as_json(options=nil)
  super(:include => [:usuario, :tipo_de_ingresso])
end

In tipo_de_ingresso model, I want to add another object nested. here:

def as_json(options=nil)
  super(:include => :entradas)
end

But when I get the the ingressos.json, I lost entradas. If I get tipo_de_ingressos.json, entradas are nested, ok, but when I get ingressos.json, they are not there.

How can I get entradas nested in tipo_de_ingresso when I call ingresso?

PS: You might find the RABL Gem helpful if you need to do more complex json operations. That way you can define actual views for your json responses instead of bundling it up in the model. — Soup

Try this,

# /app/models/Ingresso.rb

def as_json(options=nil)
  super(:include => [:usuario => {}, :tipo_de_ingresso => { :include => :entradas }])
end

EDIT:

changed [:usuario, ... to [:usuario => {}, ...

It works! I knew that was something like this, but I'm not very familiar with Rails. Thanks again :-)
