Looking for some help with extending existing classes. In a view I have <td><%=h bmevent.node %></td>. I need further processing on the output and added a helper: module ApplicationHelper class String def a self[ /^[^\0]*/ ] end end end and <td><%=h bmevent.node.a %></td> results in an undefined method `a' for #<String:0xb6c8105c> error. What am I doing wrong? The helper is correctly found, since module ApplicationHelper def b(text) text[ /^[^\0]*/ ] end end and <td><%=b bmevent.node.a %></td> produce the desired result, but this is (for other reasons) not what I want. I want to extend class string and use the postfix notation as in the first example. Any ideas ?

I would have a method like that in a file somewhere in lib (eg lib/ my_extensions.rb) and require that from an initializer. You could 'fix' it by pulling that out of the ApplicationHelper module and putting it at the bottom of the file but that's a bit horrible. Fred
