Django rest 框架 - 在设置 subb 应用程序名称中设置的问题

Question

我遇到了与this question 相同的问题，我们正在做相同的教程 .我正在研究python 3.10.1、Django 4.0、django rest framework 3.13.0。当我尝试像 Ankit Tiwari 写的那样更改我的类别 apps.py 中的名称时，我收到一个错误：

ImportError: cannot import name '_Descriptor' from 'functools' (C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.496.0_x64__qbz5n2kfra8p0\lib\functools.py)

但是当我像 Jeet Patel 那样尝试时，什么也没有发生

我的应用程序.py

from django.apps import AppConfig


class CategoryConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'category'

settings.py

INSTALLED_APPS = [
     #other basic install
    'corsheaders',
    'rest_framework',
    'rest_framework.authtoken',
    'api',
    'api.category',
]

我认为这是我设置api.category.name = api.category 时来自_Descriptor 的完整回溯，但如果我错了，我应该粘贴什么？ ：

During handling of the above exception, another exception occurred:

Answer 1

CategoryConfig 中的name 应该是api.category

class CategoryConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'api.category'
