This is like a reference table which doesnt need a controller :|
And it is a reftable for what links to display on screen.
This is what I did finally.
class Navbar < ActiveRecord::Base
def self.all_modules
NavBar.find (:display_name, :url, :conditions => {:name =>
'module_bar'}, :order => 'sort_order')
end
def self.associated_quick_links (selected_module)
NavBar.find (:display_name, :url, :default_link, :conditions =>
{:name => 'quick_links_bar', :group_by_module =>
selected_module}, :order => 'sort_order')
end
def self.associated_module (selected_quick_link)
NavBar.find (:group_by_module, :conditions => {:name =>
'quick_links_bar', :display_name => selected_quick_links})
end
end
And I am still getting
undefined local variable or method `navbar' for #<ActionView::Base:
0x4be1140>
Extracted source (around line #2):
1: <div id="content">
2: <%= debug navbar.all_modules %>
Please help
