OD305 attrs-states-removed¶

attrs and states are removed; use invisible, readonly and required expressions.

What it reports¶

An element of a view's arch that carries an attrs or states attribute, and an <attribute name="attrs"> or <attribute name="states"> spec in an inherited view that sets one.

Why it matters¶

Odoo 17.0 dropped both attributes. Each modifier is now its own attribute holding a Python expression on the record's fields: invisible, readonly, required and column_invisible. Odoo checks every view it loads for the old ones and stops the install with Since 17.0, the "attrs" and "states" attributes are no longer used. A module ported from 16.0 without rewriting its views cannot be installed at all. A demo file differs: see load failures.

A states attribute on a button listed the states that show it, so states="draft,sent" becomes invisible="state not in ('draft', 'sent')". Modules of 16.0 and earlier are not checked, since the attributes are the only way to write modifiers there.

Example¶

<field name="payment_term_id" position="after">
    <field name="client_order_ref" attrs="{'required': [('state', '=', 'sale')]}"/>
</field>

Odoo 17.0 and later refuse the view; the domain becomes a Python expression in required.

<field name="payment_term_id" position="after">
    <field name="client_order_ref" required="state == 'sale'"/>
</field>
