django import_export ..创建视图导入数据

我试图使用django导入导出模块..以下文档here ..我能够使导出视图..但导入视图不工作..这里是我的代码django import_export ..创建视图导入数据

---- views.py -----

def dataset_export(request): 
     ds=StudentResource().export() 
     response=HttpResponse(ds.xls,content_type="xls") 
     response['Content-Disposition']='filename=students.xls' 
     return response 

def dataset_import(request): 
    dataset=tablib.Dataset(['', 'New book'], headers=['usn', 'name']) 
    result=StudentResource().import_data(dataset,dry_run=False) 
    response=HttpResponse(result,content_type="xls") 
    return response

这里的学生模型

----- models.py-

class Student(models.Model): 
    name=models.CharField(max_length=30) 
    usn=models.CharField(max_length=10) 
    email=models.EmailField() 

    def __str__(self): 
     return '%s(%s)'%(self.name,self.usn) 
    class Meta: 
     ordering=["usn"]

和模型资源

class StudentResource(resources.ModelResource): 
    class Meta: 
     model=Student 
     fields = ('usn', 'name', 'email') 
     import_id_fields = ['usn','name','email']
