dmlcloud.obj_from_cfg

dmlcloud.obj_from_cfg(config, *args, **kwargs)

Creates an object from a configuration dictionary or a string.

This is equivalent to calling factory_from_cfg(config)(*args, **kwargs).

If a string is provided, it is assumed to be the path to the object (class). If a dictionary is provided, it must contain a “factory” key with the path to the object.

Additional keys in the dictionary are passed as keyword arguments to the object constructor.

Parameters:

  • config (Mapping | str) – Configuration dictionary or string with the path to the object.

  • *args – Additional positional arguments to pass to the object constructor.

  • **kwargs – Additional keyword arguments to pass to the object constructor.

Returns:

The created object.

Return type:

Any

Raises:

  • ImportError – If the object cannot be imported.

  • KeyError – If the configuration dictionary does not contain the “factory” key.

Example

>>> dml.obj_from_cfg('datetime.date', 2025, month=1, day=1)
datetime.date(2025, 1, 1)
