I have this list of users that I capture in a method which is users that  
one individual is responciable for. In my view I iterate through that  
list of users to place the name of each user into a table.

I also have this hashPassword method that takes the username and a key  
and generates the appropriate single sign on hash for a user. My problem  
is that I am iterating through the users in the view and I need to call  
that hashPassword method from the view. I have tried saying:

\<% @hash = hassPassword(. . .) %\>

But rails doesn’t like that. Is there a way to call a method from the  
view? Thanks,

-S

Sure, you can call methods from a view. Where is hashPassword defined?

It’s define in my controller and I thought you could call it too, but I  
get this error:

undefined method `hashPassword’ for #\<#Class:0x4703e48:0x4703e20\>

I got it. I added the method to the application.rb file and all is good.
