Counting array elements in Ruby (unexpected results by the count( ) function) -

-

in understanding following ruby expressions should produce same result.
apparently missing something, way serious bug go unnoticed...

# returns number of elements in array count = @quotation.quotation_items.count { |x| x.placement == current_placement}  # expect count = (@quotation.quotation_items.find_all { |x| x.placement == current_placement }).length

quotation_items above activerecord has_many association

#count not take block that.

if want use conditions on count, do:

@quotation.quotation_items.count(:conditions => "placement = #{current_placement}")
