Django Foreign Key Data saving issue

[mohit basantani]

Hello All,

I am new to Django and my problem is there are two tables Namely
Masterlist and Partlist. In masterlist i am uploading data using the
import export plugin and in my db I have created a foreign key with
refrence to partlist.

Partlist Table Columns
1. id
2. partlist_name - this is the name of the uploaded file

Now whenever i import the file, I want that first the filename should be
saved in the partlist table and then the id of that particular row is saved
in the masterlist table. But if I am doing so I am getting an error Column
'partlist_name': invalid literal for int() with base 10:
'Mastertable-2018-10-26 (2)(1).xls'

Please help as I am stuck with this!
