        tempt=[]
        for record in self:
            tempt.extend([record.batch_id])

        culling = self.env['estate.nursery.cullinglinebatch'].search([('batch_id', '!=', list(tempt))])

        return {
             'domain': {'batch_id': [('batch_id','not in',culling),('qty_abnormal','>',0)]}

        }

回答1:

In ODOO8/9 search method always return object not the Id of object.

culling = self.env['estate.nursery.cullinglinebatch'].search([('batch_id', '!=', list(tempt))])

Here culling is the object of model 'estate.nursery.cullinglinebatch'

Your domain should be look like

 'domain': {'batch_id': [('batch_id','not in',culling.ids),('qty_abnormal','>',0)]}

here i have uses culling.ids instead of culling.

I hope this will help you.
