docs: RequestSchema(strict=True) raises TypeError

[ikhlestov]

If you try to run first example from docs, you'll get an TypeError exception:

Traceback (most recent call last):
  File "app.py", line 19, in <module>
    @request_schema(RequestSchema(strict=True))
TypeError: __init__() got an unexpected keyword argument 'strict'

It looks that after marshmallow version >= 3.0 release Schema always strict.

Should we freeze marshmallow version and update docs? Or there should be some kind of another solution.

Code

This is the first snipped from the README

from aiohttp_apispec import (
    docs,
    request_schema,
    setup_aiohttp_apispec,
)
from aiohttp import web
from marshmallow import Schema, fields


class RequestSchema(Schema):
    id = fields.Int()
    name = fields.Str(description="name")

@docs(
    tags=["mytag"],
    summary="Test method summary",
    description="Test method description",
)
@request_schema(RequestSchema(strict=True))
async def index(request):
    return web.json_response({"msg": "done", "data": {}})


app = web.Application()
app.router.add_post("/v1/test", index)

# init docs with all parameters, usual for ApiSpec
setup_aiohttp_apispec(
    app=app, 
    title="My Documentation", 
    version="v1",
    url="/api/docs/swagger.json",
    swagger_path="/api/docs",
)

# Now we can find spec on 'http://localhost:8080/api/docs/swagger.json'
# and docs on 'http://localhost:8080/api/docs'
web.run_app(app)

Save it to app.py file and start with python app.py command
