设置模板的路径：setting.py
TEMPLATE_DIRS = (
'/home/django/mysite/templates',
)

动态模板路径
import os.path

TEMPLATE_DIRS = (
os.path.join(os.path.dirname(file), 'templates').replace('\','/'),
)

get_template动态加载模板
from django.template.loader import get_template
from django.template import Context
from django.http import HttpResponse
import datetime

def current_datetime(request):
now = datetime.datetime.now()
t = get_template('current_datetime.html')
html = t.render(Context({'current_date': now}))
return HttpResponse(html)

render_to_response:::::::
from django.shortcuts import render_to_response
import datetime

def current_datetime(request):
now = datetime.datetime.now()
return render_to_response('current_datetime.html', {'current_date': now})

内嵌模板：
{% include 'nav.html' %}
{% include "nav.html" %}
