Django Guardian user.has_perm false现有数据

Question

我试图使用Django Guardian授予许可。当我尝试授予现有数据的权限时，它会向我显示一个错误的消息，但是当我创建一个新对象时，它的表现为真。我做错了什么？

我的代码：

>>>from django.contrib.auth.models import User
>>>from print.models import *
>>>from guardian.shortcuts import assign_perm
>>>user = User.objects.create(username='tanvir',password='antu')
>>>excel = ExcelData.objects.all()
>>>assign_perm('delete_exceldata', user, excel)
>>>user.has_perm('delete_exceldata', excel)
>>>False

，但是如果我做

>>>from django.contrib.auth.models import User
>>>from print.models import *
>>>from guardian.shortcuts import assign_perm
>>>user = User.objects.create(username='tanvir',password='antu')
>>>excel = ExcelData.objects.create(order_number='01245632145214')
>>>assign_perm('delete_exceldata', user, excel)
>>>user.has_perm('delete_exceldata', excel)
>>>True

Answer 1

excel = ExcelData.objects.all()

会给您一个QuerySet和

excel=ExcelData.objects.create(order_number='1245632145214')

会给你一个对象..

您只能将权限分配给对象

如果要分配QuerySet的权限，请在循环中

user = User.objects.create(username='tanvir',password='antu')
excel = ExcelData.objects.all()
for obj in excel:
    assign_perm('delete_exceldata', user, obj)
    user.has_perm('delete_exceldata', obj) # this will give you status for each obj
