Question

ActiveRecord::Base.include_root_in_json = true doesn’t seem to be working in rails 3.10.rc4 and I don’t see it in the docs.

Since the root element is now off by default how do we re-enable it?

@comments.to_json in rails 3.1 now looks like

[
  {
    comment: "Fun street park.",
    created_at: 2011-06-29T02:28:29Z,
  }
]

And in previous versions it has the root node which I need to get back.

[
  {
    comment: {
      comment: "Fun street park.",
      created_at: 2011-06-29T02:28:29Z
    }
  }
]

Try setting this directly on your Comment model.

class Comment < ActiveRecord::Base
  self.include_root_in_json = true
end
