如何从Odoo8中的另一个函数字段中定义one2many字段的域？

from openerp import models, fields, api

class ModelA(models.Model):
    _name = 'model.a'

    name = fields.Char(string='Name')
    model_b_ids = fields.One2many(comodel_name='model.b', inverse_name='model_a_id', string='Model B')

    @api.multi
    def compute_model_b_ids(self):
        for record in self:
            # 根据需要的条件筛选model.b记录
            domain = [('field_name', '=', record.name)]
            model_b_records = self.env['model.b'].search(domain)
            record.model_b_ids = [(6, 0, model_b_records.ids)]

class ModelB(models.Model):
    _name = 'model.b'

    name = fields.Char(string='Name')
    model_a_id = fields.Many2one(comodel_name='model.a', string='Model A')
