A tiny framework for helping solve the common problem when using caches_action in rails apps: Still needing to show custom info for the current user, order, etc.
First it loads the JSON of the current session info, by default from /session/info.json. All the augmentations are then called with this information.
app/assets/application.js:
//= require augmentations/application
//= require augmentations
app/assets/javascripts/augmentations.js.coffee:
class Augmentations.AdminMenu extends Augmentations.Base
url: =>
'/admin/augmentations/menu.html'
# only attaches if selector exists
# @root() gives a jquery object of this selector
selector: =>
'#hd_menu'
# make a test on the session info
test: =>
@session.is_admin
# load the menu and add it to the top menu
augment: =>
$.get(@url()).success (data)=>
$(data).appendTo(@root())
$(->
# listen for sessionLoad
(new Augmentations.AdminMenu).attach()
)
