Hi @Chaanto

There are several ways that you could use to get that task done. Here I give you 2. Hope it will help you

1- Using Model load method that accept 2 arguments, fields and data. were fields is a list of fields that match the elements in the data rows meaning that the argument with the data need to be a list of rows and every row will be the list of values of the fields in the same order

Model = self.env['model.name']
result = Model.load(
    ['name', 'value'],
    [
        ['A', '1'],
        ['B', '2'],
        ['C', '3']
    ],
)

fields = ['name', 'value']
self.env.cr.copy_from(io.StringIO(
    u'\n'.join(
        u"%s\t%s\t%s\t%d" % (
            rec.name,
            rec.value
        )
        for rec in bla
    )),
    table='model_table',
    columns=fields,
)
