DRF 壮观未发现自定义身份验证扩展类

Question

当从rest_framework_simplejwt.authentication.JWTAuthentication drf-spectaulous swagger-ui 授权按钮扩展新的令牌身份验证类时，授权按钮消失并且无法添加令牌承载者，我想当您子类化时它会出错。
重现步骤：
首先，创建一个 Django 项目，其中安装有 Rest Framework 和 drf-spectaulous 以及简单的 jwt，并按照文档指导进行配置。到达 /swagger-ui/ ，它工作正常。
然后创建 JWTAuthentication 的子类，如下所示：

from rest_framework_simplejwt.authentication import JWTAuthentication as JWTA

class JWTAuthentication(JWTA):
    pass

并在您的设置中：

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

现在，如果您转到 /swagger-ui/ ，则没有授权按钮！!! 我怎样才能解决这个问题？
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'

但无法在任何地方、互联网上或文档中注册它！覆盖身份验证类时如何修复授权按钮？
编辑：按照 JPG 所说的操作并在设置中导入扩展名：

# 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：

来自文档我应该将扩展放在哪里？/ 未检测到我的扩展

扩展会自动注册。只要确保 python 解释器至少看到它们一次即可。为此，我们建议创建一个PROJECT/schema.py文件并将其导入到您的 （与和PROJECT/__init__.py相同的目录）中，并使用. 请不要导入该文件， 因为这可能会导致循环导入问题。settings.pyurls.pyimport PROJECT.schemasettings.py

原答案

这似乎是包本身的错误。在扩展身份验证扩展时，您可以使用实际的类而不是类的路径

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希望有人能从中受益！
