我已经deadsnakes在我的 Ubuntu 20.04 机器上安装了 Python 3.10。

如何使用它？python3 --version返回Python 3.8.10并python3.10 -m venv venv返回错误（我python3-venv也安装了）。

因此，要使用电子邮件作为用户名，我会像这样重写内置User模型（受到Django 源代码的启发）

模型.py

class User(AbstractUser):
    username = None
    email = models.EmailField(unique=True)
    objects = UserManager()
    USERNAME_FIELD = "email"
    REQUIRED_FIELDS = []

    def __str__(self):
        return self.email

管理员.py

@admin.register(User)
class UserAdmin(admin.ModelAdmin):
    fieldsets = (
        (None, {"fields": ("email", "password")}),
        (("Personal info"), {"fields": ("first_name", "last_name")}),
        (
            ("Permissions"),
            {
                "fields": (
                    "is_active",
                    "is_staff",
                    "is_superuser",
                    "groups",
                    "user_permissions",
                ),
            },
        ),
        (("Important dates"), {"fields": ("last_login", "date_joined")}),
    )
    add_fieldsets = (
        (
            None,
            {
                "classes": ("wide",),
                "fields": ("email", "password1", "password2"),
            },
        ),
    )
    list_display = …
