I assume you call the eruby program as the cgi handler from your webserver
(apache?).
The eruby program doesn't have a 'feature' to modify http headers that it
outputs with -Mc if I am not mistaken.
An easy solution would be to write a small wrapper:
---------------- myeruby.rb ---------------------
require 'erb'
require 'cgi'
class ErbSpace
def set_cookie(a_cookie)
@cookie ||= []
@cookie << a_cookie
end
def get_cookies
@cookie || false
end
def get_binding
binding
end
end
template = ERB.new(File.read(ARGV[0]))
es = ErbSpace.new
content = template.result(es.get_binding)
cgi = CGI.new
cgi.out('cookie'=>es.get_cookies) { content }
-----------
Now I have a set_cookie method in the erb template that I can call anywhere in
the script:
------------- test.rhtml ------------------
<% set_cookie(CGI::Cookie::new('username', 'someone')) %>
<html>
<%= "A ruby string".reverse %>
</html>
<% set_cookie(CGI::Cookie::new('another_cookie', 'test')) %>
-----------
----------- See if it works: ---------------
$ ruby myeruby.rb test.rhtml
Content-Type: text/html
Content-Length: 36
Set-Cookie: username=someone; path=
Set-Cookie: another_cookie=test; path=
<html>
gnirts ybur A
</html>
-------------------
Now just change your webserver to call myeruby.rb instead of eruby for .rhtml
files. Also this provides you a good starting point to add more methods to
ErbSpace if you need.
