如何解决 excel 上传到模型时的 XLRD 错误

Question

这是我从尝试将 excel 数据文件上传到 Django 模型的视图中得到的错误。

下面是我试图从中得出的观点。我实际上一直无法找到解决此问题的正确方法。我相信我们中的某个人一定在一个或多个实例中发现了这个错误。

def UploadTeacherView(request):
    message=''
    
    if request.method == 'POST':
        form = NewTeachersForm(request.POST, request.FILES)
        if form.is_valid():
            excel_file = request.FILES['file']
            fd, path = tempfile.mkstemp()
            try:
                with os.fdopen(fd, 'wb') as tmp:
                    tmp.write(excel_file.read())
                book = xlrd.open_workbook(path)
                print(book)
                sheet = book.sheet_by_index(0)
                obj=TeacherData(
                    code = sheet.cell_value(rowx=1, colx=1),
                    first_name = sheet.cell_value(rowx=2, colx=1),
                    last_name = sheet.cell_value(rowx=3, colx=1),
                    email = sheet.cell_value(rowx=4, colx=1),
                    phone = sheet.cell_value(rowx=5, colx=1),

                )
                obj.save()
            finally:
                os.remove(path)
        else:
            message='Invalid Entries'
    else:
        form = NewTeachersForm()
    return render(request,'new_teacher.html', {'form':form,'message':message})
