To Reproduce

my models.py

from datetime import date
from pydantic import BaseModel, Field
from pydantic.generics import GenericModel
from typing import Generic, TypeVar, Optional

T = TypeVar('T')


class RespModel(GenericModel, Generic[T]):
    code: int = Field(description="business code", example=0, default=0)
    data: T = Field(description="business data")
    msg: str = Field(description="msg", example="success", default="success")


class Test(BaseModel):
    foo: str = Field(description="Foo Description", example="FOOO")
    bar: str = "test"

@openapi.definition(
    summary="Test post api",
    parameter=[
        # query
        Parameter(name="test", schema=str, location="query"),
        # cookie
        Parameter(name="cookie", schema=str, location="cookie"),
        # header parameter
        Parameter(name="token", schema=str, location="header")
    ],
    body=RequestBody(
        {'application/json': Test.schema()}, required=True
    ),
    response=[
        Response(
            {'application/json': RespModel[Test].schema()},
            description="success",
            status=200
        )
    ],
)

Additional context
If I am using the wrong method, please point it out, thank you

This is not a bug.

I think you need to do two things:

1. Add Test as a component:

openapi.component(Test)

2. Built the RespModel with the correct ref template:

    response=[
        Response(
            {
                "application/json": RespModel[Test].schema(
                    ref_template="#/components/schemas/{model}"
                )
            },
            description="success",
            status=200,
        )
    ],

Looking at it closer, I think there is an even better solution since Pydantic is including Test inside the RespModel spec. This way, you do not need to add the Test component.

    response=[
        Response(
            {
                "application/json": RespModel[Test].schema(
                    ref_template="#/definitions/{model}"
                )
            },
            description="success",
            status=200,
        )
    ],

What/where is this #5 coming from?

[Adam Hopkins]

What is the question?

[pahrohfit]

What is the question?

In your last response, you have a ref_template value that begins with "#5" ... what is that "5", how is it resolving to anything valid?
