Importing from Django- Trying to find all fields needed for successful import

I have a fairly large database of about 2000 questions and answers(comments that I will convert to answers) that is in a custom django database. I have imported all the fields in wpposts and wppostmeta except in postmeta I imported history field as blank. Then I realized you use a custom table for ap_meta. So I was wondering if you could suggest fields I need to make it successful. Any tips would be greatly appreciated. Also as many are requesting, I would love an import tool…
