Question

我正在学习Django的一些教程，用于即将开展的项目，我无法正确加载模板。调试模式返回“ValueError”，表示“需要多于1个值才能解压”。我正在运行Django的捆绑服务器。知道问题是什么？任何帮助表示赞赏。

这是追踪：

Traceback:
File "/Library/Python/2.7/site-packages/django/core/handlers/base.py" in get_response
  111. response = callback(request, *callback_args, **callback_kwargs)

File "/Users/tinwaijosephlee/Sites/djcode/dev2/../dev2/views.py" in hours_ahead
  26. return render_to_response('plus.html', {'offset': offset, 'dt': dt})

File "/Library/Python/2.7/site-packages/django/shortcuts/__init__.py" in render_to_response
  20. return HttpResponse(loader.render_to_string(*args, **kwargs), **httpresponse_kwargs)

File "/Library/Python/2.7/site-packages/django/template/loader.py" in render_to_string
  181. t = get_template(template_name)

File "/Library/Python/2.7/site-packages/django/template/loader.py" in get_template
  157. template, origin = find_template(template_name)

File "/Library/Python/2.7/site-packages/django/template/loader.py" in find_template
  128. loader = find_template_loader(loader_name)

File "/Library/Python/2.7/site-packages/django/template/loader.py" in find_template_loader
  93. module, attr = loader.rsplit('.', 1)

这是我的观看代码：

from django.shortcuts import render_to_response
from django.http import HttpResponse

import datetime
import sys
import os

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

def hours_ahead(request, offset):
    offset = int(offset)
    dt = datetime.datetime.now() + datetime.timedelta(hours=offset)
    return render_to_response('plus.html', {'offset': offset, 'dt': dt})

这是我的urls.py

from django.conf.urls.defaults import *
from dev2.views import *

urlpatterns = patterns('',
    (r'^time/$', current_datetime),
    (r'^time/plus/(\d{1,2})/$', hours_ahead),
)

这是settings.py中的模板加载器配置

TEMPLATE_LOADERS = (
    '/Users/some_user_name/Sites/djcode/dev2/template',
)

这是模板html文件

<html><head></head><body>It is now {{ current_date }}.</body></html>

Answer 1

你在settings.py中设置了错误的内容。 TEMPLATE_LOADERS用于查找和加载模板的Python代码。您希望将目录放入TEMPLATE_DIRS。

当render_to_response时，Django View ValueError
