Answer 1

Your write method should pass field value in dictionary datastructure like

write({'is_art_approved', True})

Instead of passing it like:

write('is_art_approved', True)

And in write method ids is required param but that depends how code is written. more about write methods is here

Bests,

Answer 2

create or write methods in odoo requires a dictionary (key:value pairs) of data to be written in the database. From you error code, it shows the wrongly called write method. It should be as follows:

obj.write(cr, uid, ids, {'key':'value'}, context=<<your context>>)

where ids are the record ids for which you need to update data in the database.

Answer 3

You forgot some parameters or you used too many. the write method should contain the following parameters:

 cr #used database cursor
 uid #logged in user
 ids #id from the object youŕe writing to
 data #dictionary of data that has to be written
 context #the given context
