Rails - Jan 2008 - Passing data to a view: How prevent the instance variables ?

Greetings, i want pass data to my view without using instace variables.
Usually I  make renders to partials for pass local variables and
preventing use instace variables :

Example:

render( :partial => "filename",  :locals => {:paramName =
@anyVar} )

I''ve this method in my controller(controller.rb):

def anyMethod

var1=5
var2=6

end

There''s any way to pass var1 and var2 to the default view
anyMethod.rhtml  without use instace variables?


Thanks for any answer, Juan Pablo

I have to ask... why are you so keen on avoiding instance variables? 
Sorry, I am just curious because they are so widely the standard way of 
passing data between controller and view. I actually don''t know of any 
other way but that might be simply that I never had a need.

I just want work in a  very modular way (OO mode). And I don''t need
than
all my variables have to be with public access, that''s the reason

There is nothing wrong with passing instance variables to the view.
However, I do think its good practice to limit the number of variables
you use.  If your passing a large number of variables they can
probably be wrapped into an object, then you can just pass the
object.  For example:

def some_controller_method
  @height = 5
  @width = 10
  @depth = 2
end

compared to:

def some_controller_method
  @box = Box.new(:height => 5, :width => 10, :depth => 2)
end

Then your view calls @box.height, etc...
