Django CMS：基于所选插件的页内导航菜单

Question

我在 django cms 中有一个模板，它基于我添加到内容占位符的插件创建了一个视差网站。这是我的模板：

{% extends "foundry/base.html" %}
{% load cms_tags %}

{% block title %}{% page_attribute "page_title" %}{% endblock title %}

{% block content %}
    {% placeholder 'content' %}
{% endblock content %}

在base.html中，我使用{% show_menu 0 1 100 100 "foundry/menu.html" %}来生成菜单。我想根据添加到内容占位符的插件将项目添加到此菜单。因为 show_menu 在 cms 呈现占位符之前调用，所以我无法使用 NavigationNode 来注册我的菜单。如果我可以查询内容占位符中使用的插件，我就可以处理这个菜单。但是 Django CMS 数据库太复杂了，我找不到查询。谢谢

Answer 1

Django CMS 提供了几个实用程序来执行此操作；你只需要挖掘源代码就可以找到它们。

from cms.templatetags.cms_tags import _get_placeholder
from cms.utils.plugins import get_plugins

if request and request.current_page:
    placeholder = _get_placeholder(request.current_page, request.current_page,
        template_context, placeholder_name)  # placeholder_name is a string
    plugins = get_plugins(request, placeholder, request.current_page.get_template())

一旦你有了占位符的插件，你就可以通过以下方式在菜单上做任何你需要的定制：http://docs.django-cms.org/en/develop/how_to/menus.html

希望对你有所帮助。

以防万一您仍然对此感兴趣，这是我将 Anchor 插件插入菜单的实现：

from menus.base import Modifier, NavigationNode
from menus.menu_pool import menu_pool
from cms.models import Page
from cms.utils.plugins import get_plugins
from cms.templatetags.cms_tags import _get_placeholder

class AnchorPluginMenuModifier(Modifier):
    """

    """
    def modify(self, request, nodes, namespace, root_id, post_cut, breadcrumb):
        # if the menu is not yet cut, don't do anything
        if post_cut:
            return nodes
        # otherwise loop over the nodes        
        newnodes = []
        for node in nodes:
            try: 
                if "is_page" in node.attr and node.attr["is_page"]:

                    page_obj = Page.objects.get(id=node.id)                    
                    template_context = {
                        "request" : request,
                    }
                    placeholder_name = "content"

                    placeholder = _get_placeholder(request.current_page, page_obj,
                        template_context, placeholder_name)  # placeholder_name is a string
                    plugins = get_plugins(request, placeholder, page_obj.get_template())


                    for plugin in plugins:
                        if type(plugin).__name__ == "AnchorPluginModel":
                            newnode = NavigationNode(
                                plugin.anchor_menutitle,
                                node.url+"#"+plugin.anchor_name,
                                "{}-{}".format(page_obj.id,plugin.id),
                                node
                            )
                            newnode.parent_id = node.id
                            newnodes.append(newnode)
                            setattr(newnode, "selected", False)
                            node.children.append(newnode)                                       
            except Exception, e:
                print e
                # client.captureException()

        return nodes

menu_pool.register_modifier(AnchorPluginMenuModifier)

代码位于 cms_menus.py 文件中。
