Rails Bootstrap Navbar and refineryCMS

Does anyone have implemented the Rails Bootstrap Navbar in refineryCMS?

I'm having a hard time trying to figure out how to render the dropdown menu.

which should be the right way of accomplish this?

_menu.html.erb

<%    
  if (roots = local_assigns[:roots] || (collection ||= refinery_menu_pages).roots).present?
    dom_id ||= 'menu'
  css = [(css || 'menu'), 'clearfix'].flatten.join(' ')
    hide_children = Refinery::Core.menu_hide_children if hide_children.nil?
-%>
<div class="navbar">
  <div class="navbar-inner">
    <div class="container">

      <nav id='<%= dom_id %>' class='<%= css %> nav'>
        <ul class="nav">


          <%= render :partial => '/refinery/menu_branch', :collection => roots,
                     :locals => {
                       :hide_children => hide_children,
                       :sibling_count => (roots.length - 1),
                       :menu_levels => local_assigns[:menu_levels],
                       :apply_css => true #if you don't care about class='first' class='last' or class='selected' set apply_css to false for speed.
                     } -%>

        </ul>
        </nav>
    </div>
    </div>
</div>
<% end -%>

_menu_branch.html.erb

<%
  if !!local_assigns[:apply_css] and (classes = custom_menu_branch_css(local_assigns)).any?
    css = "class='#{classes.join(' ')}'".html_safe
  end

-%>
<li class="dropdown">
<% if menu_branch.children.present? &&  menu_branch.ancestors.length < 1 %>
<%= link_to(menu_branch.title, refinery.url_for(menu_branch.url), class: "dropdown-togle", data: { toggle: "dropdown" }) -%>
<% else %>
<%= link_to(menu_branch.title, refinery.url_for(menu_branch.url)) -%>
<% end %>
  <% if ( (children = menu_branch.children unless hide_children).present? &&
          (!local_assigns[:menu_levels] || menu_branch.ancestors.length < local_assigns[:menu_levels]) ) -%>


      <ul class="dropdown-menu">
      <%= render :partial => '/refinery/menu_branch', :collection => children,
                 :locals => {
                   :apply_css => local_assigns[:apply_css],
                   :hide_children => !!hide_children,
                   :menu_levels => local_assigns[:menu_levels]
                  } -%>

    </ul>
</li>
<% end -%>

Solution

Refinery 2.1.0 with Bootstrap 3

None of the solutions above worked for me. So I had to adapt from Valentine Konov's answer. Below you can find all of my files. You can always leave me a comment if you need any help. Here we go!

1) Check your RefineryCMS and Bootstrap versions

Gemfile

gem 'bootstrap-sass', '~> 3.1.1'
gem 'refinerycms', '~> 2.1.0'

2) Save a few lines of code

a. You actually have no need to create an app/decorators/models/refinery/page_decorator.rb file.

b. You can forget the menu_header method as well. This way, you'll have:

app/helpers/application_helper.rb

module ApplicationHelper
end

3) Now let's get to the real work

a. Override your default header with:

$ rake refinery:override view=refinery/_header.html

And change its code to:

app/views/refinery/_header.html.erb

<nav class="navbar navbar-default" role="navigation">
    <div class="container-fluid">

        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#"><%=Refinery::Core::site_name %></a>
        </div>

        <!-- Collect the nav links, forms, and other content for toggling -->
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <%= Refinery::Pages::MenuPresenter.new(refinery_menu_pages, self).to_html %>
        </div>
    </div>
</nav>

b. Now go to terminal and run rake refinery:override presenter=refinery/pages/menu_presenter. It will generate a menu_presenter.rb file. Change it to this:

app/presenters/refinery/pages/menu_presenter.rb

require 'active_support/core_ext/string'
require 'active_support/configurable'
require 'action_view/helpers/tag_helper'
require 'action_view/helpers/url_helper'

    module Pages
        class MenuPresenter
            include ActionView::Helpers::TagHelper
            include ActionView::Helpers::UrlHelper
            include ActiveSupport::Configurable

            config_accessor :roots, :menu_tag, :list_tag, :list_item_tag, :css, :dom_id,
                                            :max_depth, :selected_css, :first_css, :last_css, :list_first_css,
                                            :list_dropdown_css, :list_item_dropdown_css,
                                            :list_item__css, :link_dropdown_options, :carret

            # self.dom_id = nil
            # self.css = "pull-left"
            self.menu_tag = :section
            self.list_tag = :ul
            self.list_first_css = ["nav", "navbar-nav", "navbar-right"]
            self.carret = '<b class="caret"></b>'
            self.list_dropdown_css = "dropdown-menu"
            self.link_dropdown_options = {class: "dropdown-toggle", data: {:toggle=>"dropdown"}}
            self.list_item_tag = :li
            self.list_item_dropdown_css = :dropdown
            self.list_item__css = nil
            self.selected_css = :active
            self.first_css = :first
            self.last_css = :last

            def roots
                config.roots.presence || collection.roots
            end

            attr_accessor :context, :collection
            delegate :output_buffer, :output_buffer=, :to => :context

            def initialize(collection, context)
                @collection = collection
                @context = context
            end

            def to_html
                render_menu(roots) if roots.present?
            end

            private
            def render_menu(items)
                content_tag(menu_tag, :id => dom_id, :class => css) do

                            buffer << render_menu_item(item, index)
                        end
                    end
                end
            end

            def render_menu_item(menu_item, index)
                content_tag(list_item_tag, :class => menu_item_css(menu_item, index)) do
                    @cont = context.refinery.url_for(menu_item.url)
                    buffer = ActiveSupport::SafeBuffer.new

            end

            # Determines whether any item underneath the supplied item is the current item according to rails.
            # Just calls selected_item? for each descendant of the supplied item

            def descendant_item_selected?(item)
                item.has_children? && item.descendants.any?(&method(:selected_item?))

end

c. Restart your server and see the results. If you already have some pages created, your navbar should look similar to the one below:
