Dear All,
I am afraid I need a wee bit more help here, which is entirely related to
my limited experience with Django. Apologies.
Here is what I would like to do:
Imagine you have documents uploaded into Mayan EDMS that expire after a
given period of time, such as warranty documents.
So, I should be able to create a metadata set, that contains both the date
the documents gets uploaded into an "valid" folder, and and automatically
completed expiry metatdata field which, in Python speak, would do something
like as a minimum:
from datetime import timedelta
VALIDITY_PERIOD = 365
expiry_date = date_of_purchase + timedelta(days=VALIDITY_PERIOD)
In the stanza above, expiry_date should be calculated from another metadata
field called, for instance date_of_purchase. How can this be achieved (for
dummies!) in Mayan EDMS?
I guess once I have a worknig example on how to include Python functions in
detail, I can easily do other things.
Thanks a million!
Chris
