# so ive outlined this function
# def order_statistics_by_str(some_items_statistics)
#     some_items_statistics.sort do |one, another|
#         ones_str = one[:str]
#         another_str = another[:str]
#         -ones_str <=> another_str
#     end
# end
# however this
# ones_str = one[:str] and  another_str = another[:str]
#...

no problem, you got the idea.
try both sort and sort_by. see wc you prefer.

eg,

> sorted_hash = stats_hash.sort {|a,b| b[1][:str] <=> a[1][:str]}
=> [["first", {:str=>90.0, :total_completed=>1, :total_sold=>0}], ["second", {:str=>50.0, :total_completed=>1, :total_sold=>0}], ["third", {:str=>25.0, :total_completed=>1, :total_sold=>0}], ["fourth", {:str=>0.0, :total_completed=>1, :total_sold=>1}]]

> sorted_hash = stats_hash.sort_by {|a| -a[1][:str]}
=> [["first", {:str=>90.0, :total_completed=>1, :total_sold=>0}], ["second", {:str=>50.0, :total_completed=>1, :total_sold=>0}], ["third", {:str=>25.0, :total_completed=>1, :total_sold=>0}], ["fourth", {:str=>0.0, :total_completed=>1, :total_sold=>1}]]

if you'll note, ruby will convert the hash member into an array (see params a and b) but will not drilldown convert the subs, thus we were still able to refer to [:str]. The conversion is required since hashes are by nature unsorted/unsortable.

if you want a "sorted" hash form, you need to create another hash fr the created array, and you'll have to use ruby 1.9, eg ;)

irb(main):009:0> new_hash={}
=> {}

irb(main):010:0> stats_hash.sort_by{|a| -a[1][:str]}.each{|k,v| new_hash[k]=v}
=> [["first", {:total_completed=>1, :total_sold=>0, :str=>90.0}], ["second", {:total_completed=>1, :total_sold=>0, :str=>50.0}], ["third", {:total_completed=>1, :total_sold=>0,:str=>25.0}], ["fourth", {:total_completed=>1, :total_sold=>1,:str=>0.0}]]

irb(main):011:0> new_hash
=> {"first"=>{:total_completed=>1, :total_sold=>0, :str=>90.0}, "second"=>{:total_completed=>1, :total_sold=>0, :str=>50.0}, "third"=>{:total_completed=>1, :total_sold=>0, :str=>25.0}, "fourth"=>{:total_completed=>1, :total_sold=>1, :str=>0.0}}

irb(main):012:0> RUBY_VERSION
=> "1.9.0"

is that ok?
kind regards -botp
