Hi
I wasn''t able to find this function in Rails. Probably it already
exists somewhere- if not, maybe this will save someone 2 minutes
def human_size(size)
if size < 1.kilobyte
size + " Bytes"
elsif size < 1.megabyte
sprintf("%.0f KB", size / 1.kilobyte.to_f)
elsif size < 1.gigabyte
sprintf("%.1f MB", size / 1.megabyte.to_f)
elsif size < 1.terabyte
sprintf("%.1f GB", size / 1.gigabyte.to_f)
elsif size < 1.petabyte
sprintf("%.1f TB", size / 1.terabyte.to_f)
elsif size < 1.exabyte
sprintf("%.1f PB", size / 1.petabyte.to_f)
else
sprintf("%.1f EB", size / 1.exabyte.to_f)
end
end

It''s even called human_size via an alias. If you had tried it in a view before coding it, it would have worked! That has happened to me a couple times. Rails rocks. FYI: Here''s the implementation. Doesn''t go past TB. # File vendor/rails/actionpack/lib/action_view/helpers/number_helper.rb, line 87 def number_to_human_size(size) case when size < 1.kilobyte: ''%d Bytes'' % size when size < 1.megabyte: ''%.1f KB'' % (size / 1.0.kilobyte) when size < 1.gigabyte: ''%.1f MB'' % (size / 1.0.megabyte) when size < 1.terabyte: ''%.1f GB'' % (size / 1.0.gigabyte) else ''%.1f TB'' % (size / 1.0.terabyte) end.sub(''.0'', '''') rescue nil end --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
