Rails - Aug 2006 - [Markaby] Using cycle?

I can''t figure out how to get cycle to work:

  tr :class=>@helpers.cycle(''odd'',
''even'') do
  tr :class=>@helpers.cycle(''odd'',
''even'', :name=>''rows'') do
  tr.@helpers.cycle(''odd'', ''even'') do

The first two output only one ''class="odd"'', the
last causes an error.

Any help?

Thanks,
Joe

I believe cycle contains a closure that remembers what the last state was 
called with. So:
cycle(''odd'',''even'')
cycle(''odd'',''even'')

Would return
''odd''
''even''

You can try it out in the console. Each call "cycles". So if you put
it
into a loop, it will cycle through the options until the loop is exited.

[0,1,2].each{ |e| cycle(''odd'',''even'') }
odd
even
odd

Hope that helps.
