Hey guys,
My scenario:
A have a Custom DocType name GoodsSummary
with a Field:Link to Purchase Order. For this I need to map (or pre-populate) a child table named BookItems
(items with Purchase Receipt) and another one ‘UnBookItems’ (items without Purchase Receipt) onchange of Purchase Order:Link:Field.
I have seen the same functionality to Purchase Receipt with the button ‘Get Items’ form Purchase Order. In the source code I see a erpnext.utils.map_current_doc
that calls erpnext.buying.doctype.purchase_order.purchase_order.make_purchase_receipt
and inside there i see from frappe.model.mapper import get_mapped_doc
(frappe/mapper.py at develop · frappe/frappe · GitHub)
Basically I need to create something similar I can’t understand from get_mapped_doc
function the table_maps argument how it should be structured.
For example I see in apps/erpnext/erpnext/buying/doctype/purchase_order/purchase_order.py
I see some postprocess
and condition
or even add_if_empty
.
May I have some explanation about the get_mapper_doc
or a simplified usage example?
