【Django】模型delete返回值判断

例子：

result = DmsSysUser.objects.filter(id=request.POST.get('id')).delete()

print(type(result))

print(result)

删除成功，结果如下：

<class ‘tuple’>

(1,{‘DMS.DmsSysUser’:1})

 

删除失败，结果如下：

<class ‘tuple’>

(0,{‘DMS.DmsSysUser’:0})

 

result = DmsSysUser.objects.filter(id__gt=1).delete()

print(type(result))

print(result)

结果如下：

<class ‘tuple’>

(4,{‘DMS.DmsSysUser’:4})

 

Performs an SQL delete query on all rows in the QuerySet and returns the number of objects deleted and a dictionary with the number of deletions per object type.

 

综上可直接这样判断：

if DmsSysUser.objects.filter(id=deleteID).delete()[0] :
       print('成功')

else:

      print('失败')
