在[{'True'：True，'False'：False，'None'：None}，{}，{}，
在[{'True'：True，'False'：False，'None'：None}，{}，{}，

我得到了这个错误，在我的应用程序中查找[{'True': True, 'False': False, 'None': None}, {}, {}, ....]中的键[category]失败，我有类别和子类别，这在我的视图中重复了太多，对于每个函数和子类别，我使用了pip install django-mptt，但它是可以的，并且可以工作。所以我决定使用自定义模板标记来代替，但是现在我面临着这个错误
有关更多信息，您可以查看我的代码。myapptags.py
from django import template
from django.db.models import Sum
from django.urls import reverse
from mysite import settings
from order.models import ShopCard
from product.models import Category
register = template.Library()
@register.simple_tag
def categorylist():
return Category.objects.all()views.py的代码

from django.template.loader import render_to_string
from . models import Settings, ContactMessage, FAQ
from product.models import Category, Comment, Images, Product, Variants
from . forms import ContactForm, SearchForm
from product.forms import CommentForm
def index(request):
setting = Settings.objects.get(pk=1)
# category = Category.objects.all()
products_slider = Product.objects.all().order_by('id')[:4] #first 4 product
products_latest = Product.objects.all().order_by('-id')[:4] # latest
products_picked = Product.objects.all().order_by('?')[:4] # random
page = "index"
context = {
'setting': setting,
'page': page,
# 'category': category,
'products_slider': products_slider,
'products_latest': products_latest,
'products_picked': products_picked,
}
return render(request,'index.html',context)包含我的类别及其子类别的侧边栏
{% load myapptags %}
{% categorylist as category %}
{% load mptt_tags %}
<ul class="category-list">
{% recursetree category %}
