Declarative containers
|
|
----------------------
|
|
|
|
.. currentmodule:: dependency_injector.containers
|
|
|
|
:py:class:`DeclarativeContainer` is inversion of control container that
|
|
could be defined in declarative manner. It should cover most of the cases
|
|
when list of providers that would be included in container is deterministic
|
|
(container will not change its structure in runtime).
|
|
|
|
Declarative containers have to extend base declarative container class -
|
|
:py:class:`dependency_injector.containers.DeclarativeContainer`.
|
|
|
|
Declarative container's providers have to be defined like container's class
|
|
attributes. Every provider in container has name. This name should follow
|
|
``some_provider`` convention, that is standard naming convention for
|
|
attribute names in Python.
|
|
|
|
.. note::
|
|
|
|
Declarative containers have several features that could be useful
|
|
for some kind of operations on container's providers, please visit API
|
|
documentation for getting full list of features -
|
|
:py:class:`dependency_injector.containers.DeclarativeContainer`.
|
|
|
|
Here is an simple example of defining declarative container with several
|
|
factories:
