我正在尝试使用自定义用户模型，我正在使用AbstractBaseUser类。但是，当我尝试从管理端创建新用户时，我收到此错误：
“无法解压缩不可迭代的NoneType对象”
我能够从管理员端查看用户，但是当我尝试添加新用户时，我收到此错误。
我的自定义用户模型：

('0', 'Unverified'),

Exception Value: cannot unpack non-iterable NoneType object
你的add_fieldsets本身没有被定义为元组/列表，它只是围绕另一个元组的()。因此，您的代码只是将(None, {})视为元组，而它期待元组的元组。
您需要使用方括号或在列表的唯一元素后添加,：
add_fieldsets = (
(None, {
'classes':('wide',),
'fields':('name','username', 'email','phone','country','state','city','address','age','registration_date','password1','password2')
}
), # <-- add this comma!
)
要么
add_fieldsets = [
(None, {
'classes':('wide',),
'fields':('name','username', 'email','phone','country','state','city','address','age','registration_date','password1','password2')
}
)
] # <-- list
