如何在w中添加多级菜单支持(支持基于非wa的页面) [英] How to add multi-level menu support to wagtail (with support for non-wagtail based pages)

问题描述

如何添加对自定义菜单的支持，这些菜单也可用于非基于Wagtail的页面.

How can I add support for custom menus which will work also with non-Wagtail based pages.

1. 例如，通过直接向注册页面提供相对网址，例如"/account/registration")
2. 例如，通过直接向外部网页(例如"www.stackoverflow.com")提供绝对网址

我发现了一个非常有趣的项目:https://github.com/rkhleics/wagtailmenus 不幸的是在主菜单中不支持子菜单.

I found this very interesting project: https://github.com/rkhleics/wagtailmenus Unfortunately is does not support submenus in the main menu.

推荐答案

关于Wagtail的一件事是，我所说的数据树仅由页面组成(称为

One thing about Wagtail is that what I would call the data tree is made up only of pages (it's called a page tree). This tree is used as the basis for navigation but, of course, sometimes you might want a navigation item in this tree to be something other than a page. I accomplish what you want to do by subclassing Page:

from django.http import HttpResponseRedirect

class Node(Page):

    subpage_types = [your subpage types]
    parent_page_types = [your parent page types]

    link = models.CharField(max_length=255, default='', blank='True')

    content_panels = Page.content_panels + [
        FieldPanel('link')
    ]    

    def serve(self, request):
        if self.link is not None:
            return HttpResponseRedirect(self.link)
        else:
            pass

在模板中:

{% for item in menu_items %}
    <li>
        <a href="{% if item.specific.link and item.specific.link != '' %}{{ item.specific.link }}{% else %}{% pageurl item %}{% endif %}">{{ item.title }
        </a>
    </li>
{% endfor %}
