How Lino Così generates invoices¶
In Lino Così every delivered item will get invoiced.
General functionality for automatically generating invoices is documented in invoicing : Generating invoices.
This document contains code snippets (lines starting with >>>
) that get
tested as part of our development workflow.
>>> from lino import startup
>>> startup('lino_book.projects.cosi5.settings')
>>> from lino.api.doctest import *
Overview¶
The invoice generator is is sales.InvoiceItem
>>> rt.models_by_base(rt.models.invoicing.InvoiceGenerator)
[<class 'lino_xl.lib.trading.models.InvoiceItem'>]
We must explain to Lino how a delivery note turns into an invoice by extending
the models so that they inherit from InvoiceGenerator
.
