Hi all,

I am teaching myself rails and I can’t figure out why the following  
code does not work: ‘say’ part works, but nothing shows up for  
‘get\_new’ part.

Here is my chat\_controller.rb file:

class ChatController \< ApplicationController

def index  
end

def say  
@line = params[:say\_so]  
end

def get\_new  
end

end

* * *

Here is my index.rhtml file:

\<%= form\_remote\_tag :update =\> “put\_here”, :url =\> {:action =\> ‘say’}  
%\>  
\<%= text\_field\_tag ‘say\_so’ %\>

\<%= submit\_tag 'Say' %\> \<%= end\_form\_tag %\>

\<%= periodically\_call\_remote :url =\> {:action =\> ‘get\_new’ }, :update  
=\> ‘put\_there’, :frequency =\> 2.0 %\>

* * *

say.rhtml and get\_new.rhtml files are simply:

\<%= @line %\>

Each request gets a separate instance of ChatController, so setting  
@line to something in the say action has no effect on the value of  
@line when the get\_new action is called.
