我需要将数据放入侧边栏中。除了 context_processors 之外，还没有找到任何其他解决方案。这是最干净、最佳的方法吗？
任何帮助表示赞赏。我觉得有点奇怪，很难找到相关信息。这个问题。所以也许这对其他人也有帮助。
# animals/context_processors.py
from animals.models import Cows, Horses
from django.shortcuts import render
def allcows(request):
cows = Cows.objects.all()
return {"cows": cows}
def lasthorses(request):
horses = Horses.objects.all().order_by("-id")[:2]
return {"horses": horses}
Sidebar.html
<h1>Sidebar</h1>
<h3>All cows:</h3>
{%for cow in cows%}
<div>
The name is {{ cow.name }}, and the age of {{ cow.name}} is {{ cow.age }}.
</div>
{%endfor%}
<h3>last 2 horses:</h3>
{%for horse in horses%}
<div>
The name is {{ horse.name }}, and the age of {{ horse.name}} is {{ horse.age }}.
</div>
{%endfor%}

如果您总是需要
cowshorses# animals/context_processors.py
from animals.models import Cows, Horses
from django.shortcuts import render
def all_animals(request):
cows = Cows.objects.all()
horses = Horses.objects.order_by('-id')[:2]
return {'cows': cows, 'horses': horses}并且由于
QuerySetcowshorses注意：通常 Django 模型会被赋予一个 singular 名称 [django-antipatterns]，所以
而不是Cow。Cows
