ruby on rails - mongoid .limit does not work in mongoid 3.1.x -

i tried in rails mongoid 3.1.0 , lastest 3.1.3. .limit not work. below should return 1 row returns (4)

code:

@go = gallery.limit(1) logger.info "count: #{@go.count}" 

output:

 count: 4  moped: 54.234.11.193:10055 query database=mongohqtestdatabase collection=galleries selector=  {"$query"=>{}, "$orderby"=>{:_id=>1}} flags=[:slave_ok] limit=-1 skip=0 batch_size=nil fields=nil (276.2010 

ms)

which version of mongoid limit() ?

the limit command works fine, reason count ignores limit. if cast array you'll see limit working.

array(gallery.limit(1)).length  # gives 1 

also, if iterate through objects you'll see limit working.
