include root in json for array?

问题

rails 3: include_root_in_json = true allows to have a root property for json response. But it doesn't work with array of object, there is a property like include_root_in_array_json? actually I have this response:

[ {"model": {"a":"a_value"}}, {"model": {"b":"b_value"}}]

but I want a response like that:

{"models":[ {"model": {"a":"a_value"}}, {"model": {"b":"b_value"}}]}

xml response has a root property 'models' which include the array, but json not...

回答1:

You can try:

{models: Model.all}.to_json

It's not a very elegant solution but it does its job fine.
