:description: Dict provider helps to inject a dictionary of the dependencies. This page demonstrates
|
|
how to use Dict provider.

.. currentmodule:: dependency_injector.providers
|

|
:py:class:`Dict` provider provides a dictionary of values.

``Dict`` provider handles keyword arguments the same way as a :ref:`factory-provider`.
|
|
|
|
To use non-string keys or keys with ``.`` and ``-`` provide a dictionary as a positional argument:
|
|
|
|
.. code-block:: python
|
|
|
|
providers.Dict({
|
|
SomeClass: providers.Factory(...),
|
|
"key.with.periods": providers.Factory(...),
|
|
"key-with-dashes": providers.Factory(...),
|
|
})
|
|
|
|
Example:
|
|
|
|
.. literalinclude:: ../../examples/providers/dict_non_string_keys.py
|
|
:language: python
|
|
:lines: 3-
