Overriding of catalogs
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
Catalogs can be overridden by other catalogs. This, actually, means that
|
||
|
|
all of the providers from overriding catalog will override providers with the
|
||
|
|
same names in overridden catalog.
|
||
|
|
|
||
|
|
There are two ways to override catalog by another catalog:
|
||
|
|
|
||
|
|
- Use ``di.AbstractCatalog.override(AnotherCatalog)`` method.
|
||
|
|
- Use ``@di.override(AnotherCatalog)`` class decorator.
|
||
|
|
|
||
|
|
Example of overriding catalog using ``di.AbstractCatalog.override()`` method:
|
||
|
|
|
||
|
|
.. literalinclude:: ../../examples/catalogs/override.py
|
||
|
|
:language: python
|
||
|
|
|
||
|
|
Example of overriding catalog using ``@di.override()`` decorator:
|
||
|
|
|
||
|
|
.. literalinclude:: ../../examples/catalogs/override_decorator.py
|
||
|
|
:language: python
