<class 'Salesman.admin.UsrUserAdmin'>: (admin.E012) There are duplicate field(s) in 'fieldsets[0][1]'.

ieldsets = (
['Main', {
'fields': ('user_name', 'real_name', 'concat_name','phone_no','charge_person','charge_phone', 'status', 'status',),
}],
['Advance', {
'classes': ('collapse',), # CSS
'fields': ('nick_name', 'certificate_no','city','email','login_count'),
}]
)

注意上面有两个status 去掉一个就可以了。
