V.15 migration

Modules

Manifest
__manifest__.py

QWEB import is moved to 'assets' dict

JS import is moved to 'assets' dict

Previous declaration will not work: neither for views nor for widgets

Views

XML
templates rendering

t-raw is deprecated : use t-out

mail data might be prepared using QWEB

Need to redefine all mail templates and make sure all tags are safe

Scripts

Python
fields & methods

xmlid_to_res_id is renamed to _xmlid_to_res_id

render_template should define engine

Check all methods

JavaScript

Instead of require: use 'import from'

New logic is already implemented to many widgets, services, and views

Check whether model has attribute

if hasattr(MODEL, ATTR):
​# do something 
​pass 

Model - object, e.g. self.env["sale.order"]

Attr - field or method name, e.g. "active", "name_get"

RecordSet Operations

record in recset1 # include
record not in recset1 # not include
recset1 + recset2 # extend
recset1 | recset2 # union
recset1 & recset2 # intersect
recset1 - recset2 # difference
