Hello,
I am using Django admin to create/update some records. Now, I need to
track changes. After somebody updates a record, I need to see what was
changed and then create a text log like:
changed `name`: oldvalue -> newvalue,
changed `email`: [email protected] -> [email protected]
Where is the right place, where I have access to unchanged model values
and validated values from the submit form? The place before the model is
updated by form values? Another approach would be to save all values into
a dictionary after the model is loaded from database and in save() method
compare old and new values, but I don't know how how to call a code after
load.
Thanks,
Martin
