Question

On data import I should apply the following transformation:

if value:
    return hashlib.sha512(value + salt).hexdigest()

How can I use that with import_transform?

Answer 1

The following helped:

import_transform: "lambda x: hashlib.sha512(x.encode('utf-8') + 'actual_salt_value').hexdigest()"

Upd. the following code handles the case, when field is missed in the upload file:

import_transform: "lambda x: None if x is None or x=='' else hashlib.sha512(x.encode('utf-8') + 'actual_salt_value').hexdigest()"
