module Admin::BreadcrumbHelper |
|
# BREADCRUMB HELPER |
|
# |
|
# This module is useful anywhere you want to create a basic bread crumb |
|
# I generally use it |
|
# INSTALLATION for ADMIN DASHBOARD |
|
# 1. Save this file to app/helpers/admin/breadcrumb_helper |
|
# |
|
# INSTALLATION for NORMAL USE |
|
# 1. Save this file to app/helpers/breadcrumb_helper |
|
# 2. Change the module definition from |
|
# module Admin::BreadcrumbHelper |
|
# to simply |
|
# module BreadcrumbHelper |
|
# |
|
# USAGE |
|
# 1. Make sure all of your models have a 'name' attribute. |
|
# (If not, just make an alias in your model that points to another attribute |
|
# class SomeClass < ActiveRecord::Base |
|
# def name |
|
# title |
|
# end |
|
# end |
|
# |
|
# 2. In a view (I put it in app/views/layouts/admin.html.erb) call this: |
|
# <%= get_bread_crumb %> |
|
# |
|
# OPTIONS |
|
# You'll note I am using @breadcrumb_base_override to add a |
|
# link to the root path. This works well for me in admin dashboards, |
|
# since I can use it to link to the root path. If you don't need this, take it out |
