Odoo如何通过小部件many2many_binary为特定字段设置默认值

class MyModel(models.Model):
    _name = 'my.model'

    name = fields.Char(string='Name')
    images = fields.Many2many('ir.attachment', string='Images', widget='many2many_binary')

    @api.model
    def default_get(self, fields_list):
        defaults = super(MyModel, self).default_get(fields_list)
        default_images = [(0, 0, {'name': 'Default Image 1', 'datas': '/path/to/default_image_1.jpg'}),
                          (0, 0, {'name': 'Default Image 2', 'datas': '/path/to/default_image_2.jpg'})]
        defaults['images'] = default_images
        return defaults
