How to make breadcrumbs_on_rails render a Bootstrap compatible breadcrumb navigation
# The BootstrapBreadcrumbsBuilder is a Bootstrap compatible breadcrumb builder.
# It provides basic functionalities to render a breadcrumb navigation according to Bootstrap's conventions.
#
# BootstrapBreadcrumbsBuilder accepts a limited set of options:
# * separator: what should be displayed as a separator between elements
#
# You can use it with the :builder option on render_breadcrumbs:
# <%= render_breadcrumbs :builder => ::BootstrapBreadcrumbsBuilder, :separator => "&raquo;" %>
#
# Note: You may need to adjust the autoload_paths in your config/application.rb file for rails to load this class:
# config.autoload_paths += Dir["#{config.root}/lib/"]
#
class BootstrapBreadcrumbsBuilder < BreadcrumbsOnRails::Breadcrumbs::Builder
def render
@context.content_tag(:ul, :class => 'breadcrumb') do
@elements.collect do |element|
render_element(element)
end.join.html_safe
end
end
def render_element(element)
current = @context.current_page?(compute_path(element))
@context.content_tag(:li, :class => ('active' if current)) do
link_or_text = @context.link_to_unless_current(compute_name(element), compute_path(element), element.options)
divider = @context.content_tag(:span, (@options[:separator] || '/').html_safe, :class => 'divider') unless current
link_or_text + (divider || '')
end
end
