Steps to reproduce:

class Venue
field :coordinates, type: Array
index(

{coordinates: '2d'}

,

{min: -180, max: 180}

)
end

Have ran rake db:mongoid:create_indexes

Tried calling:

Venue.geo_near([@lat, @long])

And got:

Moped::Errors::OperationFailure:
The operation: #<Moped::Protocol::Command
@length=135
@request_id=3
@response_to=0
@op_code=2004
@flags=[]
@full_collection_name="encore_backend_test.$cmd"
@skip=0
@limit=-1
@selector={:geoNear=>"venues", :near=>[43.670906, -79.393331], :query=>{}, :spherical=>true}
@fields=nil>
failed with error "no geo index "

Any suggestions?
