magpie.constants¶
Constant settings for Magpie application.
Constants defined with format MAGPIE_[VARIABLE_NAME] can be matched with corresponding
settings formatted as magpie.[variable_name] in the magpie.ini configuration file.
Note
Since the magpie.ini file has to be loaded by the application to retrieve various configuration settings,
constant MAGPIE_INI_FILE_PATH (or any other path variable defined before it - see below) has to be defined
by environment variable if the default location is not desired (ie: if you want to provide your own configuration).

Attributes¶
- magpie.constants._get_default_log_level() magpie.typedefs.Str[source]¶
Get logging level from INI configuration file or fallback to default
INFOif it cannot be retrieved.
- magpie.constants.MAGPIE_CONSTANTS = ['MAGPIE_CONSTANTS', 'MAGPIE_ADMIN_PERMISSION', 'MAGPIE_LOGGED_PERMISSION',...[source]¶
- magpie.constants.get_constant_setting_name(name: magpie.typedefs.Str) magpie.typedefs.Str[source]¶
Find the equivalent setting name of the provided environment variable name.
Lower-case name and replace all non-ascii chars by _. Then, convert known prefixes with their dotted name.
- magpie.constants.get_constant(constant_name: magpie.typedefs.Str, settings_container: magpie.typedefs.AnySettingsContainer | None = None, settings_name: magpie.typedefs.Str | None = None, default_value: magpie.typedefs.SettingValue | None = None, raise_not_set: bool = True, raise_missing: bool = True, print_missing: bool = False, empty_missing: bool = False) magpie.typedefs.SettingValue[source]¶

Parameter
constant_nameis expected to have the formatMAGPIE_[VARIABLE_NAME]although any value can be passed to retrieve generic settings from all above mentioned search locations.If
settings_nameis provided as alternative name, it is used as is to search for results ifconstant_namewas not found. Otherwise,magpie.[variable_name]is used for additional search when the formatMAGPIE_[VARIABLE_NAME]was used forconstant_name(i.e.:MAGPIE_ADMIN_USERwill also search formagpie.admin_userand so on for corresponding constants).- Parameters:
constant_name – key to search for a value
settings_container – WSGI application settings container (if not provided, uses found one in current thread)
settings_name – alternative name for settings if specified
default_value – default value to be returned if not found anywhere, and exception raises are disabled.
raise_not_set – raise an exception if the found key is
None, search until last case if others areNoneraise_missing – raise exception if key is not found anywhere
print_missing – print message if key is not found anywhere, return
Noneempty_missing – consider an empty value for an existing key as if it was missing (i.e.: as if not set).
- Returns:
found value or default_value
- Raises:
ValueError – if resulting value is invalid based on options (by default raise missing/empty/
Nonevalue)LookupError – if no appropriate value could be found from all search locations (according to options)
