undefined method `length’ for Enumerable Enumerator on text_helper.rb:50:in `truncate’
With rails 2.0.2 and ruby 1.8.7 you can find this error using rails truncate helper
To solve this problem, paste this code in your enviroment.rb (eof).
module ActionView
module Helpers
module TextHelper
def truncate(text, length = 30, truncate_string = "...")
if text.nil? then return end
l = length - truncate_string.chars.to_a.size
(text.chars.to_a.size > length ? text.chars.to_a[0...l].join + truncate_string : text).to_s
end
end
end
end
Have a nice day!
