解决方案
Refinery 2.1.0 with Bootstrap 3
以上解决方案都不适合我.所以我不得不适应瓦伦丁科诺夫的回答.您可以在下面找到我的所有文件.如果您需要任何帮助，您可以随时给我留言.来了！
1) 检查您的 RefineryCMS 和 Bootstrap 版本
Gemfile
gem 'bootstrap-sass', '~>3.1.1'gem 'refinerycms', '~>2.1.0'
2) 节省几行代码
一个.您实际上无需创建 app/decorators/models/refinery/page_decorator.rb 文件.
B.您也可以忘记 menu_header 方法.这样，您将拥有:
app/helpers/application_helper.rb
module ApplicationHelper结尾
3) 现在让我们开始真正的工作
一个.使用以下内容覆盖默认标题:
$ rake 炼油厂:覆盖视图=炼油厂/_header.html
并将其代码更改为:
app/views/refinery/_header.html.erb
<div class="container-fluid"><!-- 品牌和切换被分组以获得更好的移动显示--><div class="navbar-header"><button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"><span class="sr-only">切换导航</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span><a class="navbar-brand" href="#"><%=Refinery::Core::site_name %></a>
<!-- 收集导航链接、表单和其他用于切换的内容--><div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><%= Refinery::Pages::MenuPresenter.new(refinery_menu_pages, self).to_html %>
</nav>
B.现在转到终端并运行 rake精炼厂:override presenter=refinery/pages/menu_presenter.它将生成一个 menu_presenter.rb 文件.改成这样:
app/presenters/refinery/pages/menu_presenter.rb
需要'active_support/core_ext/string'需要'active_support/configurable'需要'action_view/helpers/tag_helper'需要'action_view/helpers/url_helper'模块炼油厂模块页面类 MenuPresenter包括 ActionView::Helpers::TagHelper包括 ActionView::Helpers::UrlHelper包括 ActiveSupport::Configurableconfig_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 = "拉左"self.menu_tag = :sectionself.list_tag = :ulself.list_first_css = ["nav", "navbar-nav", "navbar-right"]self.carret = '<b class="caret"></b>'self.list_dropdown_css = "下拉菜单"self.link_dropdown_options = {class: "dropdown-toggle", data: {:toggle=>"dropdown"}}self.list_item_tag = :liself.list_item_dropdown_css = :dropdownself.list_item__css = nilself.selected_css = :activeself.first_css = :firstself.last_css = :last定义根config.roots.presence ||集合.roots结尾attr_accessor :context, :collection委托 :output_buffer, :output_buffer=, :to =>:语境def 初始化(集合，上下文)@collection = 集合@context = 上下文结尾def to_htmlrender_menu(roots) 如果roots.present?结尾私人的def render_menu(items)content_tag(menu_tag, :id => dom_id, :class => css) 做render_menu_items(items)结尾结尾def render_menu_items(menu_items)如果 menu_items.present?content_tag(list_tag, :class => menu_items_css(menu_items)) 做menu_items.each_with_index.inject(ActiveSupport::SafeBuffer.new) do |buffer, (item, index)|缓冲< menu_item_css(menu_item, index)) 做@cont = context.refinery.url_for(menu_item.url)缓冲区 = ActiveSupport::SafeBuffer.new如果 check_for_dropdown_item(menu_item)缓冲<
c.重新启动服务器并查看结果.如果您已经创建了一些页面，您的导航栏应该类似于下面的:

解决方案
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 Refinery
module Pages

: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
render_menu_items(items)
end
end
def render_menu_items(menu_items)
if menu_items.present?
content_tag(list_tag, :class => menu_items_css(menu_items)) do
menu_items.each_with_index.inject(ActiveSupport::SafeBuffer.new) do |buffer, (item, index)|
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
if check_for_dropdown_item(menu_item)
buffer << link_to((menu_item.title+carret).html_safe, "#", link_dropdown_options)
else
buffer << link_to(menu_item.title, context.refinery.url_for(menu_item.url))
end
buffer << render_menu_items(menu_item_children(menu_item))
buffer
end
end
def check_for_dropdown_item(menu_item)
(menu_item!=roots.first)&&(menu_item_children(menu_item).count > 0)
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
# unless it first quickly determines that there are no descendants.
def descendant_item_selected?(item)
item.has_children? && item.descendants.any?(&method(:selected_item?))
end
def selected_item_or_descendant_item_selected?(item)
selected_item?(item) || descendant_item_selected?(item)
end
# Determine whether the supplied item is the currently open item according to Refinery.

path = path.force_encoding('utf-8') if path.respond_to?(:force_encoding)
# Ensure we match the path without the locale, if present.
if %r{^/#{::I18n.locale}/} === path
path = path.split(%r{^/#{::I18n.locale}}).last.presence || "/"
end
# First try to match against a "menu match" value, if available.
return true if item.try(:menu_match).present? && path =~ Regexp.new(item.menu_match)
# Find the first url that is a string.
url = [item.url]
url << ['', item.url[:path]].compact.flatten.join('/') if item.url.respond_to?(:keys)
url = url.last.match(%r{^/#{::I18n.locale.to_s}(/.*)}) ? $1 : url.detect{|u| u.is_a?(String)}
# Now use all possible vectors to try to find a valid match
[path, URI.decode(path)].include?(url) || path == "/#{item.original_id}"
end
def menu_items_css(menu_items)
css = []
css << list_first_css if (roots == menu_items)
css << list_dropdown_css if (roots != menu_items)
css.reject(&:blank?).presence
end
def menu_item_css(menu_item, index)
css = []
css << list_item_dropdown_css if (check_for_dropdown_item(menu_item))
css << selected_css if selected_item_or_descendant_item_selected?(menu_item)
css << first_css if index == 0
css << last_css if index == menu_item.shown_siblings.length
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:
