you will find this by serching in odoo base for invisible and readonly option and how to apply based on condition

In the place of attrs you can use condition directly in the invisible or readonly like this 
Without 'and' or 'or' condition

invisible = "state == 'new' "
readonly ="state != 'in_progress'"

With 'and' or 'or' condition

invisible = "state == 'new'  and martial_status == 'single'"
readonly ="state != 'in_progress' or martial_status == 'single'"

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

so what can be use instead this

 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,
