Rails - Apr 2006 - acess local variables from helper?

if I call a helper method from inside a partial, it doesn''t appear to
have
access to the partials local variables. is there a way to make them avilable 
without passing them as parameters?

here''s a simple example

# in the view
<%= render :partial => "my_partial", :locals => :value =>
2%>

# _my_partial.rhtml  - raises "undefined local variable or method
`value''"
<%= show_value %>

# helper method
def show_value
    value
end

My first thought is that you could make value an attribute (though that
means they''re no longer local), so you''d have

# in the view
<% @value = 2 %>
<%= render :partial => "my_partial" %>

# _my_partial.rhtml  - raises "undefined local variable or method
`value''"
<%= show_value %>

# helper method
def show_value
    @value
end


But to me it seems better to just pass your values in as parameters.

I''m not sure if instance variables are practical in this case because
the
partial gets rendered many times (as a collection). Thanks for your 
suggestion though.
