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

如果咱们须要用到 Hbase 的话，能够仿照 Mysql 一样，把相干的信息配置写入到 settings 文件中，然而我遇到了一个问题，就是无奈导入。

In [12]: settings.HBASE---------------------------------------------------------------------------AttributeError                            Traceback (most recent call last)<ipython-input-12-22bd47148938> in <module>----> 1 settings.HBASE~\.virtualenvs\twitter-5Z0qCgub\lib\site-packages\django\conf\__init__.py in __getattr__(self, name)     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---------------------------------------------------------------------------AttributeError                            Traceback (most recent call last)<ipython-input-13-1ee0306304e8> in <module>----> 1 settings.HBase~\.virtualenvs\twitter-5Z0qCgub\lib\site-packages\django\conf\__init__.py in __getattr__(self, name)     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'

后果问题的排查发现，在 Django 的配置文件 settings 中，必须应用全副大小能力被导入。

HBase --> HBASE

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

须要改为

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

大小写谬误! 不要的 Django 的配置文件 settings 中混合应用大小写，必须全副是大写!

从上面的文件中能够看到要害代码 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)
