Dependency provider
|
|
===================
|
|
|
|
.. currentmodule:: dependency_injector.providers
|
|
|
|
:py:class:`Dependency` provider is a placeholder for the dependency of the specified type.
|
|
|
|
The first argument of the ``Dependency`` provider specifies a type of the dependency. It is
|
|
called ``instance_of``. ``Dependency`` provider controls the type of the returned object to be an
|
|
instance of the ``instance_of`` type.
|
|
|
|
The ``Dependency`` provider must be overridden before usage. It can be overridden by any type of
|
|
the provider. The only rule is that overriding provider must return an instance of ``instance_of``
|
|
dependency type.
