I can''t figure out what is going wrong.
In a helper I have this line:
elsif player.send(next_period) == (''none'' ||
''bench'' )
html_holder << " O"
This works for "none" but doesn''t seem to work for
"bench". I have
double checked to make sure the attribute is set to exactly
''bench'' with
no spaces or case differences.
Is the condition syntax correct? can I go:
if x == (''none'' || ''one'' ||
''two'' || ''three'')
or should I be doing it differently? I suppose I could be using a
regular expression but an even more desirable way would be to test a
string against a simple array of string options. I''ve thumbed through
my ruby books but couldn''t find the answer.

So the above is the same as if x == ''none'' Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
