Odoo migration Cheatsheet

v17

(xml) attrs

The field "attr" is not supported since v17. Replace it with :

• invisible : invisible="{PYTHON}"
• readonly : readonly="{PYTHON}"

(py) group_expand

The related function now takes only two arguments after self. The last one (order) has been removed.

v18

(xml) tree

<tree> is replaced by <list>. This implies :

• You might want to update all your <xpath>

• Also replace it in all your custom views

• Also update your action records, the view_mode field

v19

(py) model._sql_constrains

The models field _sql_constrains has been removed. Replace it by several attributes using models.Constraint, models.Index and models.UniqueIndex
