如何在没有Django的其余部分的情况下使用Django模板？

pip install djangorestframework django-template-engine

django-admin startproject django_app
cd django_app/

# Settings

# MEDIA

# TEMPLATES

from django.template import engines
from django.contrib.admin.helpers import MediaHelper

    sources = []
    template_source, _, template_name = template_name.lower().partition("_")
    
    try:
        template_string, context_instance = engines['django'].from_string(template_name), {}
    except Exception as e:
        print(f"Error loading: {e}")
        return sources
    
    if template_source:
        sources = [
            MediaHelper(source=template_source) if any([
                '__media__' in source.name.lower()
                for source in sources])
            else
            MediaHelper(source=template_source.replace("admin", "admin_").replace("app_settings", ""))
        ]
        
    return (template_string, template_name, True, sources)
