上传fi时的AttributeError

Question

我有一个建议模块，我想添加一个允许用户上载文件的字段：

class file_upload (models.Model):
    _name="mod.progress.fileupload"
    name=fields.Char('name')
    type=fields.Char('type')
    content=fields.Binary()

    @api.model
    def create(self, vals):
         vals.update({            
            'name': base64.encode(self.content.filename),
            'type':base64.encode(self.content.mimetype),
        })
        return super(file_upload, self).create(vals)

class mod_progress(models.Model):
    _name="mod.progress"
    attachement_id = fields.Many2one('mod.progress.fileupload', 'Attachement')

我经常会遇到这样的错误：

Traceback (most recent call last):
return super(JsonRequest, self)._handle_exception(exception)

'name': base64.encode(self.content.filename),
AttributeError: 'bool' object has no attribute 'filename'

我刚才加了这句话vals.update更新地址：

print(type(self.content), dir(self.content))

这是输出：
