我是Django CMS的新手,我尽我所能避免询问,但这个让我发疯。 我创建了一个带有Topic和Category模型的Wiki应用程序。我将它连接到CMS上的网站并将其添加到我的菜单中。现在我希望能够显示所有顶级类别,他们的子类别&主题,以及这些主题的子类别,等等,在我的菜单上。
Menu/Navigation should look like this:
Wiki
Category1
Category1.1
Topic
Category1.2
Topic
Category2
Topic
Category3
...
Right now i can only show the Top categories:
Wiki
Category1
Category2
Category3
我已经创建了一个menu.py来获取我的Wiki上的自定义子菜单(您在上面看到的那个):
menu.py
class WikiSubMenu(CMSAttachMenu):
name = _("Wiki Sub-Menu")
def get_nodes(self, request):
nodes = []
categories = Category.objects.filter(parent_id__isnull=True)
for c in categories:
node = NavigationNode(
mark_safe(c.name),
c.get_absolute_url(),
c.id,
)
nodes.append(node)
return nodes
menu_pool.register_menu(WikiSubMenu)
我的分类模型:
class Category(models.Model):
''' Category model. '''
name = models.CharField(max_length=100)
slug = models.SlugField(unique=True)
description = models.TextField(blank=True)
parent = models.ForeignKey(
'self',
null=True,
blank=True,
related_name='children'
)
sort = models.IntegerField(default=0)
class Meta:
ordering = ['sort', 'name']
def __unicode__(self):
return self.name
@models.permalink
def get_absolute_url(self):
return ('topics:categories_category_detail', (), {'slug': self.slug})
def get_all_children(self):
return Category.objects.filter(parent=self)
现在,是否可以为包含Childs的所有类别及其Childs及其Childs创建Sub-SubMenu,等等?
感谢您的帮助&抱歉英文不好

我刚发现:
docs.django-cms.org/en/3.0.6/extending_cms/app_integration.html#integration-modifiers
(删除直接链接添加2个新链接,对不起)
我认为这就是我正在寻找的,我有点失明,我没有找到它。如果问题解决了,我会尝试并发布答案。

改编者对我没有用,但我得到了更多的东西, 我再次阅读Docs,发现我可以给NavigationNodes一个可选的attr dictonary,我用parent = c填充所有类别,就这样我有我需要的数据,然后我发现真的很好bootstrap dropdown menu,这确实是我想要的。所以我的代码到现在为止看起来像这样:
menu.py
class TopicsSubMenu(CMSAttachMenu):
name = _("Wiki Sub-Menu")
def get_nodes(self, request):
nodes = []
categories = Category.objects.filter(parent_id__isnull=True)
for c in categories:
node = NavigationNode(
mark_safe(c.name),
c.get_absolute_url(),
c.pk,
attr=dict(
subcategories=Category.objects.filter(parent=c),),
)
nodes.append(node)
return nodes
我的模板:
menu.html
{% for child in children %}
<li>
{% if child.children %}
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
{{ child.get_menu_title }}
<span class="caret">
</span>
</a>
<ul class="dropdown-menu multi-level" role="menu" aria-labelledby="dropdownMenu">
{% for child in child.children %}
{% if child.attr.subcategories.count %}
<li class="dropdown-submenu">
<a tabindex="-1" href="#">{{ child.get_menu_title }}</a>
<ul class="dropdown-menu">
{% for subcategory in child.attr.subcategories %}
<li>
<a tabindex="-1" href="{{ subcategory.get_absolute_url }}">{{ subcategory }}</a>
</li>
{% endfor %}
</ul>
</li>
{% else %}
<li><a href="{{child.get_absolute_url}}">{{ child.get_menu_title }}</li></a>
{% endif %}
{% endfor %}
</ul>
{% else %}
<a href="{{ child.get_absolute_url }}">
<span>
{{ child.get_menu_title }}
</span>
</a>
{% endif %}
</li>
{% if class and forloop.last and not forloop.parentloop %}
{% endif %}
{% endfor %}
我的下一步是写整个&#34; for&#34;从方法中的模板循环,使用while循环或其他东西递归,并将结果发布为Answer。
我希望我能用这些东西帮助别人:)
答案 0 :(得分:5)
WOHO!我终于做到了!
base.html文件
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
{% show_menu 0 100 100 100 "menu.html" %}
</ul>
</div>
menu.html:
{% for child in children %}
<li class="child{% if child.selected %} selected{% endif %}{% if child.ancestor %} ancestor{% endif %}{% if child.sibling %} sibling{% endif %}{% if child.descendant %} descendant{% endif %}{% if child.children %} dropdown{% endif %}">
<a {% if child.children %}class="dropdown-toggle" data-toggle="dropdown"{% endif %} href="{{ child.attr.redirect_url|default:child.get_absolute_url }}">
<span>{{ child.get_menu_title }}</span>{% if child.children|length %}<span class="caret"></span>{% endif %}
</a>
{% if child.children %}
<ul class="dropdown-menu multi-level" role="menu" aria-labelledby="dropdownMenu">
{% show_menu from_level to_level extra_inactive extra_active "dropdownmenu.html" "" "" child %}
</ul>
{% endif %}
</li>
{% if class and forloop.last and not forloop.parentloop %}{% endif %}
{% endfor %}
和我的dropdownmenu.html: (递归的东西从这里开始)
{% load i18n menu_tags cache mptt_tags %}
{% for child in children %}
<li {% if child.children %}class="dropdown-submenu"{% else %} {% endif %}>
<a tabindex="-1" href="{{ child.attr.redirect_url|default:child.get_absolute_url }}">{{ child.get_menu_title }}</a>
{% if child.children %}
<ul class="dropdown-menu">
{% show_menu from_level to_level extra_inactive extra_active "dropdownmenu.html" "" "" child %}
</ul>
{% endif %}
</li>
{% endfor %}
最重要的是menu.py:
class TopicsSubMenu(CMSAttachMenu):
name = _("Wiki Sub-Menu")
def get_nodes(self, request):
nodes = []
categories = Category.objects.all()
for c in categories:
node = NavigationNode(
mark_safe(c.name),
c.get_absolute_url(),
c.pk
)
if c.parent:
node.parent_id = c.parent_id
nodes.append(node)
topics = Topic.objects.all().exclude(category__isnull=True)
for t in topics:
node = NavigationNode(
mark_safe(t.title),
t.get_absolute_url(),
t.pk,
t.category.all()[0].id,
parent_namespace="TopicsSubMenu"
)
nodes.append(node)
return nodes
menu_pool.register_menu(TopicsSubMenu)
就是这样!
