Simple spacial not working.

[paterson]

I've code like this:

field :geo, type: Array, spacial: true
spacial_index :geo

I've run rake db:mongoid:create_indexes and I keep getting :

Problem:
    Invalid index specification on CarPark: [[:geo, "2d"]], {}
Summary:
    Indexes in Mongoid are defined as a hash of field name and direction/2d pairs, with a hash for any additional options.
Resolution:
    Ensure that the index conforms to the correct syntax and has the correct options.

I'm sure I'm missing something really simple, what is it? :)
