新手Django网址，视图和模板 - 这个难以置信的简单django项目怎么可能会失败？ [英] Newbie Django urls, views, and templates - how can this incredibly simple django project possibly be failing?

问题描述

当用户登陆 http://127.0.0.1:8000/ 时，我想显示一个html页面说欢迎。当用户进入 http://127.0.0.1:8000/time/ 时，我想显示当前时间。我已经按照指示t和点我的每一个。我的设置如下。为什么我继续得到一个TemplateDoesNotExist错误？

When the user lands at http://127.0.0.1:8000/ I would like to display an html page that says "welcome." When the user goes http://127.0.0.1:8000/time/ I would like to display the current time. I have followed instructions to the t and dotted every i. My settings are below. Why do I continue to get a TemplateDoesNotExist error?

views.py

from django.template.loader import get_template
from django.shortcuts import render
import datetime

def current_datetime(request):
    now = datetime.datetime.now()
    current_datetime_template = get_template('current_datetime.html')
    context_dict = {'current_date': now}
    return render(request, current_datetime_template, context_dict)

def welcome(request):
    welcome_template = get_template('welcome.html')
    context_dict = {'username' : 'Sally Jenkins'}
    return render(request, welcome_template, context_dict)

urls.py

from django.conf.urls.defaults import patterns, include, url
from simpletest.views import welcome, current_datetime

urlpatterns = patterns('',
    url(r'^time/$', current_datetime),
    url(r'^$', welcome),
)

< hr>

---

settings.py

... # all defaults ommitted here - I changed nothing.
TEMPLATE_DIRS = (
    os.path.join(os.path.dirname(__file__), 'templates').replace('\\','/'),
)

在我的django项目目录中，我有一个名为 templates ，它包含 base.html ， current_datetime.html 和 welcome.html

In my django project directory I have a directory called templates and it contains base.html, current_datetime.html, and welcome.html just as expected.

请告诉我我忽略了什么。

Please tell me what I have overlooked.

谢谢

更多信息：

我正在使用virtualenv。事实上，我在 / Users / quanda / dev / django-projects / 中有两个django项目有什么区别吗？我不能想像会的。一个被称为开花，是我正在开展的主要项目。另一个被称为简单测试，我使其非常简单，以便我可以隔离我在开花项目中遇到的问题。我正在为这两个项目使用相同的虚拟环境。从django-projects /运行 tree -L 2 提供以下结构：

I am using virtualenv. Does the fact that I have two django projects in the /Users/quanda/dev/django-projects/ make any difference? I can't imagine it would. One is called "blossom" and is the main project I am working on. The other is called "simpletest" and I made it extremely simple so that I could isolate the issue I was having in my blossom project. I am using the same virtual environment for both projects. Running tree -L 2 from django-projects/ gives the following structure:

.

│   ├── __init__.py
│   ├── __init__.pyc

推荐答案

您正在传递模板对象而不是模板名称，如traceback中所示：

You're passing a template object instead of the template name, as shown here in the traceback:

/Users/quanda/dev/django-projects/simpletest/templates/<django.template.base.Template object at 0x102963910> (File does not exist)
...
File "/Users/quanda/dev/django-projects/simpletest/../simpletest/views.py" in current_datetime
  9.     return render(request, current_datetime_template, context_dict)

不要传递变量 current_datetime_template - 只需将'current_datetime.html'作为字符串传递，如下所示：

Don't pass the variable current_datetime_template - just pass 'current_datetime.html' as a string, like so:

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