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

Django custom configuration error: AttributeError:'Settings' object has no attribute'HBase'

If we need to use Hbase , we can imitate the Mysql and write the relevant information configuration into the settings file, but I encountered a problem, that is, it cannot be imported.

In [12]: settings.HBASE

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

The results of the investigation to find the problem, in Django profile settings , you must use the full size in order to be imported.

HBase --> HBASE

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

Needs to be changed to

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

Django error! Do not mix capitalization in the configuration file settings , it must be all uppercase!

You can see the key code 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)
