Hi,

In odoo 17 some attributes are no longer used.

ie,

eg:

instead of attribute, attrs="{'invisible':[('state','=',new)]}"you can use invisible = "state = 'new' "

Hope it helps

 Hello, 

In odoo 17.0 not use “attrs” and “states”  attributes

field name=”demo” attrs=”{‘invisible’:[(‘state’, ‘!=’,‘draft’)] ‘readonly’:[(‘state’ , ‘==’,’done’)]}/ >

 instead of ,  Use attrs and states like Below code,

field name=”demo” invisible=”state != ‘draft’ ”  readonly=”state == ‘done’ ”/ >

 I hope this is helpful to you.

 Thanks & Regards,

Hello!

Attrs is no longer used in v17, now you can directly use, for example, to dynamically set the invisible field the invisible attribute and an expression, like the following:

invisible="marital not in ['married', 'cohabitant']"/>
