AttributeError: 'AdminSite' 对象没有属性 'Register'

当我进行迁移并打开我的管理部分以添加虚拟信息和图像时，我收到错误消息。

admin.site.Register(Bet, BetAdmin)

到目前为止，我所做的是删除并按回车键，看看它是否是类上的缩进错误。

我还安装了 pylint 以根据建议的答案查看有关错误的更多详细信息。

Class has no objects member

pip install pylint-django

然后我添加到我的settings.json

   {
    "terminal.integrated.shell.windows": "C:\\WINDOWS\\Sysnative\\WindowsPowerShell\\v1.0\\powershell.exe",
    "workbench.colorTheme": "PowerShell ISE",
    "python.pythonPath": "C:\\Users\\taylo\\AppData\\Local\\Programs\\Python\\Python38-32\\python.exe",
    "json.schemas": [

    ],
    "python.linting.pylintArgs": [
        "--load-plugins=pylint_django"
    ],

    "[python]": {

    }

}

但它并没有解决任何与问题相关的问题。

仅供引用:我在堆栈上进行了大量搜索和查看，但解决方案看到了拼写错误的位置，例如拼写错误的单词，例如 reqister 而不是 register 拼写错误，并且没有拼写错误。

Answer 1

admin.site.register() - R 必须是小写
