带有计算字段的过滤器不起作用 [Odoo 8]

Question

我必须在树视图中显示发票的附件数量。没关系，我正在用计算机来做。

我还必须能够过滤附有文件的发票，这就是问题所在。我无法在搜索中使用此字段，因为它没有 store=True 属性，如果我添加它，计算属性将停止工作

我正在调查，有一个 search=" " 属性可以放在字段上 我现在就是这样，但出于某种原因，它对我不起作用。

attachment_count = fields.Integer(string="QAF", compute='count_attachments', search='_search_att_count')

    @api.one
    def count_attachments(self):
        # code

    def _search_att_count(self, operator, value):
        field_id = self.search([])
        if operator == '=':
            field_id = [x.id for x in field_id if x.attachment_count == value]
        return [('id', 'in', field_id)]

我收到此错误：

且数连续

Answer 1

您的“if”条件代码很好。

此行中的问题：

field_id = self.search([])    # return a list of recordsets

改成

field_id = self.search([]).ids   # return a list of record ids
