# Outpost::Breadcrumbs
#
# Super-simple breadcrumbs for you and me.
# Include it into a controller
#
# Arguments:
# Pairs of strings. Title of breadcrumb, Path
#
# Usage:
# In the controller:
#
# class PostsController < ApplicationController
# def new
# breadcrumb "New", outpost_new_post_path
# @post = Post.new
# end
# end
#
# This module then makes the "breadcrumbs" helper
# available to you (and me), which can be used in
# your view:
#
# <% breadcrumbs.each do |crumb| %>
# <%= link_to crumb.title, crumb.link %>
# <% end %>
#
# You can also define multiple breadcrumbs at once.
# Every 2 arguments is a new breadcrumb:
#
# breadcrumb "Edit",
# outpost_edit_post_path(@post.id),
# @post.title, outpost_post_path(@post)
#
# Don't want the crumb to be linked? Just leave the
# second argument off, or +nil+ if you're defining
# multiple breadcrumbs:
#
# breadcrumb "Edit", nil, @post.title
#
module Outpost
class Breadcrumb
attr_accessor :title, :link
end
#---------------
module Breadcrumbs
extend ActiveSupport::Concern
included do
attr_reader :breadcrumbs
if self < ActionController::Base
helper_method :breadcrumbs
end
end
#--------------
# Use this method to add breadcrumbs.
# See Outpost::Breadcrumbs
# for usage.
def breadcrumb(*args)
@breadcrumbs ||= []
args.each_slice(2).map do |pair|
crumb = Outpost::Breadcrumb.new
crumb.title = pair[0]
crumb.link = pair[1]
@breadcrumbs.push crumb
end
end
end
