AttributeError: ''module'' object has no attribute ''_create_unverified_context''

Python脚本提示如下错误：

Traceback (most recent call last):
  File "XXX.py", line 7, in <module>
    ssl._create_default_https_context = ssl._create_unverified_context()
AttributeError: ''module'' object has no attribute ''_create_unverified_context''

_create_unverified_context属性在Python2.7.9版本后才加入，如果你用的2.7.9之前的版本出现上述错误，则下载安装2.7.9之后的版本即可解决该问题。目前Python2.7的最新版本号是2.7.17。

AttributeError: ''Settings'' object has no attribute ''HBase''

django 自定义配置报错： AttributeError: ''Settings'' object has no attribute ''HBase''

如果我们需要用到 Hbase 的话，可以仿照 Mysql 一样，把相关的信息配置写入到 settings 文件中，但是我遇到了一个问题，就是无法导入。

In [12]: settings.HBASE
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

     81         if self._wrapped is empty:
     82             self._setup(name)
---> 83         val = getattr(self._wrapped, name)
     84
     85         # Special case some settings which require further modification.

AttributeError: ''Settings'' object has no attribute ''HBASE''

In [13]: settings.HBase
---------------------------------------------------------------------------

     84
     85         # Special case some settings which require further modification.

AttributeError: ''Settings'' object has no attribute ''HBase''

结果问题的排查发现，在 Django 的配置文件 settings 中，必须使用全部大小才能被导入。

HBase --> HBASE

HBase = {
    ''default'': {
        ''HOST'': ''192.168.31.245'',
        ''PORT'': 9090
    }
}

需要改为

HBASE = {
    ''default'': {
        ''HOST'': ''192.168.31.245'',
        ''PORT'': 9090
    }
}

大小写错误! 不要在 Django 的配置文件 settings 中混合使用大小写，必须全部是大写!

从下面的文件中可以看到关键代码 if setting.isupper():

django/conf/__init__.py

class Settings:
    def __init__(self, settings_module):
        # update this dict from global settings (but only for ALL_CAPS settings)
        for setting in dir(global_settings):
            if setting.isupper():
                setattr(self, setting, getattr(global_settings, setting))

        # store the settings module in case someone later cares
        self.SETTINGS_MODULE = settings_module

        mod = importlib.import_module(self.SETTINGS_MODULE)

        tuple_settings = (
            "INSTALLED_APPS",
            "TEMPLATE_DIRS",
            "LOCALE_PATHS",
        )
        self._explicit_settings = set()
        for setting in dir(mod):
            if setting.isupper():
                setting_value = getattr(mod, setting)

                if (setting in tuple_settings and
                        not isinstance(setting_value, (list, tuple))):
                    raise ImproperlyConfigured("The %s setting must be a list or a tuple. " % setting)
                setattr(self, setting, setting_value)
                self._explicit_settings.add(setting)

AttributeError: 'Settings' object has no attribute 'TEMPLATE_CONTEXT_PROCESSORS'

使用Xadmin，执行makemigrations和migrate时运行报错提示：

AttributeError: ''Settings'' object has no attribute ''TEMPLATE_CONTEXT_PROCESSORS''

第一个解决办法：

setting.py文件添加以下信息：

TEMPLATE_CONTEXT_PROCESSORS = (
 ''django.contrib.auth.context_processors.auth'', ''django.core.context_processors.auth''
 ''django.core.context_processors.debug'', ''django.core.context_processors.media'', ''django.core.context_processors.static'', ''django.core.context_processors.tz'', ''django.contrib.messages.context_processors.messages'', ''learn_models.context_processors.test'',)

第二个解决办法：

https://github.com/sshwsfc/xadmin下载源码，因为github该Bug被修复了，而pypi没有更新导致的。
