获取序列最小的记录的id

Question

我有这个班级

name = fields.Char("Name")
sequence = fields.Integer("Sequence")
description = fields.Text("Description")

我需要一种搜索​​方法来查找序列较低的id

Answer 1

res = self.env['your.model'].search([], limit=1, order='sequence desc')

应该诀窍

Answer 2

我认为这个搜索功能可以解决问题。

def _find_register(self, operator, value):
    lowest_sequence_id = False
    lowest_sequence = False
    for state in self.env['ags.traffic.operation.state'].search([('id','>',0)]):
        if not lowest_sequence:
            lowest_sequence_id = state.id
            lowest_sequence = state.sequence
        elif state.sequence < lowest_sequence:
            lowest_sequence = state.sequence
    return [('id', '=', lowest_sequence_id)]
