我是Django CMS的新手,我正竭尽所能避免发问,但这使我发疯。我制作了一个带有主题和类别模型的Wiki应用程序。我将其挂接到CMS上的站点,并将其添加到菜单中。现在,我希望能够在菜单上显示所有顶级类别,其子类别和主题以及这些子类别,等等。
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来在我的Wiki上获得一个Custom SubMenu(您在上面看到的一个):
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)
我的类别模型:
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,是否可以为所有带有子级,子级,子级和子级的类别创建Sub-SubMenu?
感谢您的帮助,对不起,英语不好
- 编辑 : -
我刚发现:
docs.django-cms.org/en/3.0.6/extending_cms/app_integration.html#integration-modifiers
(已删除直接链接以添加2个新链接,对此表示抱歉)
我认为这是我正在寻找的东西,我有点盲目未找到。我会尝试一下,如果可以解决,请发布答案。
-编辑(再次):-
修改器对我不起作用,但我又做了整整一遍,再次阅读了文档,发现可以给NavigationNodes一个可选的attr字典,这样我就可以用parent = c填充所有类别我有了所需的数据,然后我发现了真正不错的bootstrap下拉菜单,它确实可以满足我的需求。所以到目前为止,我的代码如下所示:
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
和我的模板:
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 %}
我的下一步将是从模板中的方法中编写整个“ for”循环,并使用while循环或类似内容使其递归,并将结果发布为Answer。
我希望我可以帮助某人:)
WOHO!我终于做到了!
base.html
<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 :(递归的内容从这里开始)
{% 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!
