Python 创建多个销售订单

我正在尝试根据crm.lead中的输入字段（产品数量）创建多个销售订单

@api.multi
def create_sale(self):
    values = {
        'opportunity_id': self.id,
        'state': 'draft',
        'date_order': datetime.now(),
        'partner_id': self.partner_id.id
    }

    print '###############', self.product_quantity
    for i in range(0, self.product_quantity):
        print '$$$$$$$$$$$$$$$$'
        res = self.env['sale.order'].create(values)
        print res

我收到以下弹出的错误消息

Error, a partner cannot follow twice the same object.

---

我也遇到了同样的问题，在深入搜索之后，我在邮件模块中发现了一个独特的约束，

addons/mail/models/mail\u followers.py

_sql_constraints = [
    source of problem =====>   ('mail_followers_res_partner_res_model_id_uniq', 'unique(res_model,res_id,partner_id)', 'Error, a partner cannot follow twice the same object.'),
    ('mail_followers_res_channel_res_model_id_uniq', 'unique(res_model,res_id,channel_id)', 'Error, a channel cannot follow twice the same object.'),
    ('partner_xor_channel', 'CHECK((partner_id IS NULL) != (channel_id IS NULL))', 'Error: A follower must be either a partner or a channel (but not both).')
]

然后，我使用SQL查询创建我的记录，在您的例子中：

@api.multi
def create_sale(self):
    opportunity_id: self.id,
    state: 'draft',
    date_order: datetime.now(),
    partner_id: self.partner_id.id
    current_uid = self.env.user.id

    print '###############', self.product_quantity
    for i in range(0, self.product_quantity):
        print '$$$$$$$$$$$$$$$$'
        res = self.env['sale.order'].create(values)
        result = self.env.cr.execute(("""INSERT INTO sale_order""" 
        """ (opportunity_id, state, date_order, partner_id, create_date, create_uid)"""
        """ VALUES (%s, '%s', '%s', %s, '%s', %s)""")% (
        opportunity_id, state, date_order, partner_id, date_order, current_uid))

@Khelili，谢谢分享。添加上下文对我来说很好。我通过谷歌搜索找到了它

    for i in range(0, self.product_quantity):
        values = {
            'name': self.env['ir.sequence'].next_by_code('sale.order'),
            'opportunity_id': self.id,
            'state': 'draft',
            'date_order': datetime.now(),
            'partner_id': self.partner_id.id,
            'count_total': self.total_count,
            'product_categ': self.product_categ.id
        }
        res = self.env['sale.order'].with_context(mail_create_nosubscribe=True).create(values)

在我的例子中，我的模型有一个名为“channel\u id”的字段，它与追随者channel\u id混淆了。我花了一段时间才弄清楚。

这很好，这是一个重要的答案，谢谢分享，请接受你的答案。
