I can do this case my_variable when "1", "3" "5" ..... when "8", "9" ..... else .... end but I can not do this in the view. Am I missing something here or do I have to use nested IF in the view.

yes, sorry
<% case my_variable %>
tried <%= case my_variable %>
neither one worked.
i will look at the code as to having it in the model or in the
controller, but i don''t think it would work.
eventually i did if [ "1", "3", "8",
"15"].any? { |x|.....}
and got it to work.

Just for reference, you use <% %> to simply evaluate the code and <%= %> when you want the evaluation rendered into the view. Depending on what you''re trying to inject into the view, you could put the case in the controller and use it to put the name of a partial in an instance variable, then use a render :partial=>@my_partial_view as an alternative. BTW, Phlip was right -- you didn''t get quick responses because there was not enough info for us to help.

OhMyRuby wrote:> yes, sorryYou _still_ didn''t post enough code!> neither one worked.eRB can''t interpret code structured like this. I think you did this: <% case %> <% when %> <% ... %> <% when %> <% ... %> <% when %> <% ... %> <% end %> Think of eRB as a way to declare HTML inside strings delimited by %> < %. This might work: <% case when %>... <% when %>... <% when %>... <% end %> If you don''t see the difference yet, compare to an if statement! -- Phlip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
