i am trying to pass the title form model to a template for nav dropdown but it is working in main html page but not showing others
问题
我正在尝试创建一个导航下拉菜单，其中包含模型标题，但它只在主HTML页面上显示下拉菜单，而在其他页面上不显示，我还尝试创建一个带有标题的头部HTML模板，但标题也不显示，那么我如何将对象传递给多个模板？
我的模板下拉菜单：
<li class="menu-has-children"><a href="#services">所有服务</a>
<ul style="display: inline;">
{% for detailinfo in detail.all %}
<li><a href="{% url 'details' services.slug %}">{{ detailinfo.title }}</a></li>
{% endfor %}
</ul>
</li>
我的视图：
def details(request, services_slug):
q = services.objects.filter(slug=services_slug)
if q.exists():
q = q.first()
else:
return HttpResponse("<h1>页面未找到</h1>")
detail = {'detail': q}
return render(request, 'detail.html', detail,)
我想在详情页面中添加这些对象。
def homepage(request):
aboutinfo = aboutpage.objects
servicesinfo = services.objects
programinfo = prgm.objects
return render(request, 'index.html', {'aboutinfo': aboutinfo, 'servicesinfo': servicesinfo, 'programinfo': programinfo})

你不能。
如果你想在其他页面显示“detail”，那么页面视图必须具有“detail”。
我的方法是收集我在所有视图中使用的变量，并将它们与所有视图组合在一起。
例如;
# general.py
payload = {'detail': x_variable, 'loremipsum': 2}
这是我的通用payload，我在项目的每个视图中导入这个payload。
然后在所有视图中;
# 例如，你的视图
def details(request, services_slug):
......
detail = {'detail': q}
detail.update(my_imported_payload)
return render(request, 'detail.html', detail,)
重要编辑：有一种更好的方法来做这件事。请搜索Django中的上下文处理器！
英文:
You can't.
If you want showing detail for other pages, the pages view must have detail.
My method is to collect the variables I use everywhere and combine them with all views.
For example;
# general.py
payload = {'detail': x_variable, 'loremipsum': 2}
this is my general payload and i import this payload every view in my project.
then in all views;
# your view for example
def details(request, services_slug):
.........
detail = {'detail': q}
detail.update(my_imported_payload)
return render(request, 'detail.html', detail,)
IMPORTANT EDIT : There was a better way to do this. Please search the context processors in django!
