Add route to generate Open Api Specification
--------------------------------------------
aiohttp_pydantic provides a sub-application to serve a route to generate Open Api Specification
reading annotation in your PydanticView. Use *aiohttp_pydantic.oas.setup()* to add the sub-application
.. code-block:: python3
from aiohttp import web
from aiohttp_pydantic import oas
app = web.Application()
oas.setup(app)
By default, the route to display the Open Api Specification is /oas but you can change it using
*url_prefix* parameter
.. code-block:: python3
oas.setup(app, url_prefix='/spec-api')
If you want generate the Open Api Specification from several aiohttp sub-application.
on the same route, you must use *apps_to_expose* parameters
.. code-block:: python3
from aiohttp import web
from aiohttp_pydantic import oas
app = web.Application()
sub_app_1 = web.Application()
oas.setup(app, apps_to_expose=[app, sub_app_1])
Demo
====
Have a look at `demo`_ for a complete example
.. code-block:: bash
git clone https://github.com/Maillol/aiohttp-pydantic.git
cd aiohttp-pydantic
pip install .
python -m demo
Go to http://127.0.0.1:8080/oas
