Nice solution, but not very flexible. For such things I developed a
plugin
(site_map) which is hosted on rubyforge. You can install it with:
./script/plugin install
svn://rubyforge.org/var/svn/site-map/trunk/site_map
The basics are:
- in routes.rb define your site map:
SiteMap.draw do |map|
map.area 'public do
map.section ‘about_us’, :controller => ‘frontend’, :action =>
‘about_us’
map.section ‘signup’, :controller => ‘account’
map.location :controller => ‘frontend’ # not bound to any
particular
section
end
map.area ‘admin’ do
map.section ‘users’, :controller => ‘/admin/users’
map.section ‘posts’ do
map.location :controller => ‘/admin/posts’
map.location :controller => ‘/admin/comments’
end
end
end
- Then in the views there is a current_location helper which returns an
object that describes current location. It has all the location
attributes
(area name, section name, etc) initialized based on current request
params
(including controller and action names)
You can use any attributes you want (zone / area / section / etc), there
is
no predefined ones (except you can’t use “location” attribute, because
it is
reserved keyword).
In your views you can use some helpers like
<%= section_link ‘users’, ‘User management’, :controller =>
‘/admin/users’
%>
which is defined in helpers as:
def section_link(section_name, title, url_options)
if current_location.section == section_name
# selected section
link_to title, url_options, :class => ‘selected’
else
# normal section
link_to title, url_options
end
end
This saves me from adding new stylesheets if I add new subdivisions to
my
web applications. It also gives greater flexibility in mapping
controllers
AND actions to different “locations”. Also, you can render selected e.g.
“section” with simple text (not a link). With css solution you can’t do
that.
