Global Controls

I’m coming from an ASP.NET background. Perhaps someone with some .net
experience can shed some light on how to best implement this type of
in rails. In .net I usually have global user controls that I embed on
almost every page using a Master page. For example, I’ll have a
PrimaryNav.ascx with has a codebehind file to pull the navigation schema
from the database. I include this user control in the a master page so
default it appears on every page. I’m trying to figure out how in rails
do something like this. I’ve thought about including a partial in a
but I don’t know where the business logic to pull a dynamic navigation
schema would reside. Any help is greatly appreciated, thanks!

Personally, in most cases I would go down the road of a partial in the
layout. You can populate your instance varaible using a before filter
you application controller

class ApplicationController < ActionController::Base

before_filter :set_user_menu

def set_user_menu
logic in here to setup the instance variables for the menu

By using a before filter in your application contoller you can be sure
the data will be available for your partial.

If you have situations in a controller where you don’t want this to
use the skip_before_filter

class MyController < ApplicationController
skip_before_filter :set_user_menu, :only => [ ‘login’, ‘signup’]


Hope that helps…
