ruby on rails - include_root_in_json from controller

Question

I'm trying to return a result to a view where the json does not include the root.

I don't want to set this on all actions for this model,so therefore am trying to avoid setting

ActiveRecord.Base.include_root_in_json = false

I was hoping that I could do

@task = Tasks.all
@task.include_root_in_json = false

To get the response I need, but that doesn't seem to be working, returning an 'undefined method include_root_in_json= for #

Is there a nice way of doing this??

Answer 1

It's an old question now, but the answers were not updated, and Rails 3.2 filled the gap (Rails source)

With Rails 3.2, you can now use:

my_model.to_json(:root => false)

if you don't want the root key to be included.

It gets even better as I just tested it with an array, so you can do:

Model.all.to_json(:root => true)
