breadcrumbs_on_rails rendering twice

Question

I am trying to get my breadcrumbs to follow my navigation history through different controllers

Application Controller

add_breadcrumb 'Home', root_path

In my public_pages controller

class PublicPagesController < ApplicationController


def index

end

def news
 add_breadcrumb "News", news_path
 add_breadcrumb "Contact us", contact_path
end

def contact_us
add_breadcrumb "News", news_path
add_breadcrumb "Contact us", contact_path
end

so i have another controller called private_pages which is only accessible when a user logs in, and this has its own root_path,

How would i show breadcrumbs when accessing different actions in different controllers

Thanks

Answer 1

First, add the home breadcrumb to your ApplicationController as that should be registered for every request. If your application is not publicly accessible in this regard, then disregard that, and keep the home breadcrumb in your PublicPagesController before the methods.

Then, update your PublicPagesController:

class PublicPagesController < ApplicationController

  def index
  end

  def news
    # to show Home / Contact Us / News
    add_breadcrumb "Contact Us", news_path
    add_breadcrumb "News", news_path
  end

  def contact_us
    add_breadcrumb "Contact Us", news_path
  end

end

The above assumes that add_breadcrumb "Home", news_path is called in your ApplicationController.

In regards to bootstrap conflicts or integration, see these two:

If you want to amend the home breadcrumb based on whether user is logged in or not, add a before_filter to your ApplicationController:

before_filter :set_home_breadcrumb

def set_home_breadcrumb
  if user_signed_in?
    add_breadcrumb "Home", :user_home_path
  else
    add_breadcrumb "Home", :root_path
  end
end
