i want to put null many2one field in my condition , how should i write ?


def wtc_approval(self, cr, uid, ids,vals, context=None):
        user = self.pool.get("res.users").browse(cr, uid, uid)['groups_id']
        line = self.browse(cr, uid, ids, context=context)
        for x in line.app_line :

@ajeng yes that is what I have suggested, if you don't have any value in the "x.pelaksana" then the way I have shown, it will work.. Let me know if I got it right. else we can work it out.

you can just write as

if y == x.group_id and not x.pelaksana:

    <<your code>>

If there will not be any value in "pelaksana" then according to this, your code will be executed.


Hope this helps!!
