Upload and process a file in django admin

Question

I have two models, Course and Student. I want to include a file upload field to the Course form in the admin, to accept a CSV file that I will process and store as one or more records in the Students table. My questions are:

1. How can I add this "transient" field to the Course model, without it being a column or something in the corresponding table?
2. Where should I do the file processing? I was thinking perhaps overriding the save_model method in the CourseAdmin class will do it, am I right?

Answer 1

1 - You can override a form class in admin. Create you own ModelForm and add necessary field there 2 - After that, override form_save or form's save() method and process your file there
