DRF 壮观没有发现自定义身份验证扩展类

Question

当从 rest_framework_simplejwt.authentication.JWTAuthentication drf-spectacular swagger-ui 扩展一个新的令牌认证类时，授权按钮消失并且无法添加令牌持有者，我猜当你子类化时它会出错。
重现步骤：
首先，创建一个 Django 项目，其中包含 rest 框架和 drf-spectacular 和简单的 jwt，并使用文档指导进行配置。到 /swagger-ui/ 并且它工作正常。
然后创建一个 JWTAuthentication 的子类，如下所示：

from rest_framework_simplejwt.authentication import JWTAuthentication as JWTA

class JWTAuthentication(JWTA):
    pass

在您的设置中：

REST_FRAMEWORK = {
    'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema',
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'path_to_your_module.JWTAuthentication',
    ),
}

现在如果你去 /swagger-ui/ 那里没有授权按钮！！！我该如何解决这个问题？
我什至尝试创建一个 AuthenticationExtension，例如：

from drf_spectacular.contrib.rest_framework_simplejwt import SimpleJWTScheme

class SimpleJWTTokenUserScheme(SimpleJWTScheme):
    target_class = 'path_to_your_module.JWTAuthentication'

但是没有办法在任何地方、在互联网上或在文档中注册它！ 覆盖身份验证类时如何修复授权按钮？？
编辑：做 JPG 所说的并在设置中导入扩展：

# settings.py
from path.to.custom.extension import SimpleJWTTokenUserScheme
REST_FRAMEWORK = {
    'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema',
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'path_to_your_module.JWTAuthentication',
    ),
}

引发异常：

来自文档Where should I put my extensions? / my extensions are not detected

扩展会自动注册。只要确定 python 解释器至少看到它们一次。为此，我们 建议创建一个PROJECT/schema.py 文件并将其导入您的 PROJECT/__init__.py（与settings.py 和urls.py 相同的目录） 与import PROJECT.schema。 请不要将文件导入 settings.py，因为这可能会导致循环导入问题。

原答案

这似乎是包本身的一个错误。您可以在扩展 auth 扩展 时使用 实际类 而不是 类路径 >

from drf_spectacular.contrib.rest_framework_simplejwt import SimpleJWTScheme
from path.to.custom.jwt.auth import JWTAuthentication

class SimpleJWTTokenUserScheme(SimpleJWTScheme):
    target_class = JWTAuthentication

我在这里创建了一个简单的例子，drf-spectacular-example，希望有人从中受益！！！
