I''m using hivelogic''s email enkoder and need help with a
simple if/else
statement. If there is a value for participant.student.email I would
like to create the hyperlink for the email address, if not I would just
like to list their name with no link. Can someone tell me how to do
this? I can''t seem to get it to work or find any good information on
using nil with IF/ELSE statements.
[code]@name = "#{participant.student.last_name},
#{participant.student.first_name}"
@email = participant.student.email
if !@email.nil?
enkode_mail(@email, @name)
else
@name
end[/code]

Looks OK to me, but I don''t know how enkode_mail works. Maybe you meant to assign the result of enkode_mail(..) to @email? @email = enkode_mail(@email, @name) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

In all likelihood, what''s happening is you''re getting an empty string back from the database when it''s not present. Also, you might consider using unless instead of if !: unless @email.blank? enkode_mail @email, @name else @name end Ben --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
