in my view:
<% if @main_singer_1 == @your_singer %>
<% if @main_drummer_1 == @your_drummer %>
i want to have this in a loop so i can change _1
How would I do this.
I have some idea but I am not sure.
[1…20].each do …
and then replace _1 with each of the numbers
or if someone can show the code to do this.
number = “1”
<% if @main_singer_‘number’ == @your_singer %>

Well you can do this with instance_variable_get but it sounds like you
could make things easier for your self by having arrays @main_singers
and @main_drummers
Fred
so if number = 1
you would use <% if @main_singer_instance_variable_get(number) ==
@your_singer %> ?

No, what am I doing, No it doesn’t work I am way to too tired.
opps. I got it
<% if instance_variable_get(@main_singer#{num}) == … %>
thanks Frederick C.
Rather than have your controller create all those individual variables,
have it pass the singers and drummers in arrays. Then you can loop
through the array w/code like this:
<% @main_singer.each do |singer| %>
<% if singer == @your_singer then %>
blah blah blah
<% end %>
<% end %>
