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 -%>
nav_bar snippet
<%= nav_bar :fixed => :top, :brand => "Fashionable Clicheizr 2.0", :responsive => true do %>

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'

end
def menu_items_css(menu_items)

css.reject(&:blank?).presence
end
def menu_item_children(menu_item)
within_max_depth?(menu_item) ? menu_item.children : []
end
def within_max_depth?(menu_item)
!max_depth || menu_item.depth < max_depth
end
end
end
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:

Faced for some hours with same issue. Have solution with bit more pretty code (or just more close to refinery standarts), I believe, its better to override base Refinery menu_presenter first of all take a look a bit simmilar quest http://refinerycms.com/guides/menu-presenter and this one too: http://refinerycms.com/guides/extending-controllers-with-decorators
So. Based on that article lets do this
app/decorators/models/refinery/page_decorator.rb:
Refinery::Page.class_eval do
def self.menu_pages
where :show_in_menu => true
end
end
app/helpers/application_helper.rb
module ApplicationHelper
def menu_header
menu_items = Refinery::Menu.new(Refinery::Page.menu_pages)
presenter = Refinery::Pages::MenuPresenter.new(menu_items, self)
presenter.first_css = nil
presenter.last_css = nil
presenter
end
end
in terminal run:
cd /path/to/app/
rake refinery:override presenter=refinery/pages/menu_presenter
It will generate app/presenters/refinery/pages/menu_presenter.rb change it to this:
require 'active_support/core_ext/string'
require 'active_support/configurable'

almost done. add menu_header.to_html to your menu inside container of your menu like this:
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<a class="brand" href="#"><%=Refinery::Core::site_name %></a>
<%= menu_header.to_html %>
</div>
</div>
</div>
PS: RefineryCMS 2.1.0

回答4:
The approach outlined by user1852788 worked for me. If you are using a menu with drop downs don't forget to load the bootstrap js in your application.js manifest file:
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require_tree .
And then call the dropdown function (I have a file called layout.js.coffee):
$('.dropdown-toggle').dropdown()

This Gist worked great for me for the latest of Refinery and Bootstrap https://gist.github.com/npflood/2d3f5fc44518ef231195
回答6:
There is a gem that tries to solve this problem.
https://github.com/ghoppe/refinerycms-bootstrap
But I've been having problems with it personally.
回答7:
I found much easier way to do this for refinerycms 2-0-stable
my solution is the following:
first _menu.html.erb update css variable with bootstrap classes and add necessary html for example I added div to wrap ul
<%
# Collect the root items.
# ::Refinery::Menu is smart enough to remember all of the items in the original collection.
if (roots = local_assigns[:roots] || (collection ||= refinery_menu_pages).roots).present?
dom_id ||= 'menu'
css = [(css || 'pull-right')].flatten.join(' ')
hide_children = Refinery::Core.menu_hide_children if hide_children.nil?
-%>
<nav id='<%= dom_id %>' class='<%= css %>'>
<div class="collapse navbar-collapse">
<ul class="nav nav-pills navbar-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>
</div>
</nav>
<% end -%>
second _menu_branch.html.erb update class with bootstrap classes
<%
if !!local_assigns[:apply_css] and (classes = menu_branch_css(local_assigns)).any?
css = "class='#{classes.join(' ')}'".html_safe
end
-%>
<% if ( (children = menu_branch.children unless hide_children).present? &&
(!local_assigns[:menu_levels] || menu_branch.ancestors.length < local_assigns[:menu_levels]) ) -%>
<li class="dropdown">
<a href="<%= refinery.url_for(menu_branch.url) %>" class="dropdown-toggle" data-toggle="dropdown"><%= menu_branch.title %><b class="caret"></b></a>
<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>
<% else -%>
<li<%= ['', css].compact.join(' ').gsub(/\ *$/, '').html_safe %>>
<%= link_to(menu_branch.title, refinery.url_for(menu_branch.url)) -%>
<% end -%>
</li>
now your menu should display fine. To enable Active you just need to update /config/initializers/refinery/core.rb file by changing the following code:
change selected, to active
# CSS class selectors for menu helper
config.menu_css = {:selected=>"active", :first=>"first", :last=>"last"}
