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

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)
正文完
