python的openapi生成器不适用于子类型或anyOf/allOf

Question

这是我的yaml（setup.yml）：

openapi: 3.0.2
info:
  title: "My Setup"
  description: "Some old nonsense"
  version: 1.0.0
  contact:
    name: "Tom Riddle"
    email: "tom@not-a-muggle.co.uk"
    url: "https://deatheaters-anonymous.org"
  termsOfService: MIT
servers: []
paths: {}
components:
  schemas:
    CodeValue:
      type: integer
      minimum: 200
      maximum: 302
    AgeGroup:
      type: string
      enum: [baby, child, teen, adult, old]
    Age:
      anyOf:
        - type: string
          enum: [baby, child, teen, adult, old]
        - type: integer

运行openapi生成器（从https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/4.3.1->；openapi-generator-cli-4.3.1.jar下载）并使用java -jar openapi-generator-cli.jar generate -g python -i setup.yml -o src运行cli，我得到以下结果：

1. src/openapi_client/models包含age.py和age_group.py。。。但是没有{}--><为什么
2. 文件age_group.py看起来不错。枚举在那里，我可以看到值，等等。太好了
3. 文件age.py甚至与yaml定义不相似（见下文）。没有检查值是整数还是字符串（即anyOf没有正确实现），也没有提及枚举的痕迹。事实上，在生成的项目结构中找不到它---&燃气轮机<为什么
