将 Django 从 1.6.5 升级到 1.8.4 时出现问题

Question

我是 Django 升级的新手，我尝试将版本从 1.6.5 升级到 1.8.4。我使用 sudo python setup.py install 手动安装了 1.8.4。当我开始 pycharm 时，出现以下错误。我检查了 __init__.py 以检查错误并试图找出 1.8.4 的示例文件以供参考。有人可以解释一下 - 如何逐步解决这些错误。

django.core.exceptions.ImproperlyConfigured: The TEMPLATE_DIRS setting must be a tuple. Please fix your settings.

TEMPLATE_DIR:

import os
CURRENT_PATH = os.path.dirname(os.path.dirname(__file__))
TEMPLATE_DIRS = (
 CURRENT_PATH + '/templates'
)

Answer 1

这个：

TEMPLATE_DIRS = (
     CURRENT_PATH + '/templates'
)

是不是一个tuple，它只是CURRENT_PATH + 'templates'字符串。构成 tuple 的不是括号而是逗号，即：

>>> t = ("aaa")
>>> t
'aaa'
>>> type(t)
<type 'str'>
>>> t = "aaa", "bb"
>>> t
('aaa', 'bb')
>>> type(t)
<type 'tuple'>
>>> t = "aaa",
>>> t
('aaa',)
>>> type(t)
<type 'tuple'>
>>>

唯一的例外是空 tuple 的乱码表达式（我假设是出于可读性原因？）拼写为 () 而不是 ,

除此特殊情况外，tuple 文字周围的括号在技术上是无用的，仅用于提高可读性。
