Roo cannot display spreadsheet, method unfound

Question

I am using roo and would like to preview a spreadsheet by following the document says:
<%= spreadsheet @rspreadsheet, ["Tabelle"] %>
But the error says "undefined method `spreadsheet' " I don't know if i missed any gem.

BTW, I've added the 'spreadsheet' gem, while i feel it it nothing to do with this problem.

That's a different thing. You have to `require` file for working with it. — WarHog, Nov 25 '11 at 05:14
You use `spreadsheet` in you view, you shouldn't require it in your controller. Try to add `<% require 'roo' %>` in the beginning of you view. — WarHog, Nov 25 '11 at 06:58

Roo doesn't seem to require the rails helper module.

require 'roo/roo_rails_helper'

in the controller works for me.

If you use Rails 3, you need to write

<%= raw spreadsheet @rspreadsheet, ["Tabelle"] %>

in the view.
