我遇到通過簡單地添加到INSTALLED_APPS可以「解決」（不migrate）的錯誤：爲什麼Django Rest Framework試圖驗證請求？
'django.contrib.auth',
'django.contrib.contenttypes',
根據調試輸出，似乎這個錯誤發生，因爲Django的REST框架試圖驗證請求，該請求需要Auth應用程序，該應用程序需要權限和ContentTypes，所有這些都已被刪除。 APIView只使用query_params從request，沒有別的。它接受如圖全球DRF設置：
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES':(),
'DEFAULT_PERMISSION_CLASSES':(),
'DEFAULT_RENDERER_CLASSES': ('common.rest.JSONRenderer',),
'DEFAULT_CONTENT_NEGOTIATION_CLASS': 'common.rest.IgnoreNegotiation',
}
調試輸出：
RuntimeError at /mac/pins/
Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

爲什麼是嘗試進行身份驗證的要求？我怎樣才能阻止它？
