The above code here is a function which takes csv file as an input and converts into python dictionary format and adds into the database. the code was working properly until i added month field into the model . after adding the month field i altered in the forms.py models.py csv_file also i added the month detail.
现在，如果我添加csv文件，我将得到一个错误

这是我上载的csv文件，因为我说过它首先获取了数据，但现在我收到了此错误。
