When I change the prices of Price List Item, I need log these operations.
Does erpnext have logger for specific doctype?
maybe I should use hooks? something like this?
doc_events = {
"Item Price": {
"on_update": ""
}
}
but it seems not right. I need to log price_before and price_after.
You can hook to validate
, you will get old values from db.
And… How can I get both old value and new value at one time?
you will get both values on validate.
How can get before and after values?
before_value: use frappe.db,get_value
funciton
after values: you can directly access from current obj, most likely doc.fieldname
Thanks !!
