How about the follow code snippet? where we can query if row with the same title exists? if yes, update it. Of course, to be able to do the query, we need to rely on the uniqueness of the title field.
def post_init_func(row):
c = Category.query.filter_by(name=row['category']).first()
result = Post.query.filter_by(title=row['title']).first()
if result:
result.body = row['body']
result.pub_date = row['pub_date']
result.category = c
p = result
else:
p = Post(row['title'], row['body'], c, row['pub_date'])
return p
