Rails - Jun 2006 - controller instance methods available in rhtml?

In rhtml, you have access to controller.  I am trying to set an instance var
in my controller, then retrieve it in my form display.  I know I could do
this through one of the hashes I have access to, but I''m trying to
understand why I can''t do it this way.

No matter what, when I try to output from my rhtml either
<%= controller.whynot || ''Unknown'' %> or <%= 
controller.othermessage ||
''Unknown'' %> I don''t get the values I''m
setting.  Here''s some of the ways I
try:

class ApplicationController < ActionController::Base

  attr_accessor :othermessage

  def whynot=(msg)
    @msg = msg
  end

  def whynot
    @msg
  end

class AgentsController < ApplicationController

  def show
    othermessage = ''show set''
    whynot=''jim''
    @agent = Agent.find(params[:id])
  end

Hi Jim.

I think the controller makes it''s instance variables avaiIable to the
view.  At least you can use it as though it does.  Instead of using
<%= controller.whynot ...-%>

you would just use
<%= @msg | "Whatever" %>

Alternatively if you want to have these methods available in your
views then use


class ApplicationController < ActionController::Base

  attr_accessor :othermessage

  def whynot=(msg)
    @msg = msg
  end


  def whynot
    @msg
  end

helper_method :whynot

...snip ...

That way you can use the whynot method directly in your views.

eg
<%= whynot || "Whatever" %>

Hope this helps ( & is strictly correct.)
