Should/can schema coerce datatype?

[proximous]

Is it possible to use a schema to coerce a datatype with querystring_schema or match_info_schema?

For example:

class MyBool(Schema):
    mybool = fields.Boolean()

@querystring_schema(MyBool)
async def my_func(request: web.Request):
    mybool = request.query.getone('mybool')
    dtype = type(mybool)  # this will be a string not a bool`

example call:
curl http://localhost:8080/my_func_url?mybool=true

Should/can the schema coerce 'mybool' to a type bool? Ideally the schema would coerce the datatype rather than me having to do so within my function.

Figured out I was using the wrong dereference and should have been using:

mybool = request["querystring"]
