python - Odoo 12 无法启动自定义模块 - TypeError: unsupported operand type(s) for -: 'tuple' and 'datetime.timedelta'

Question

我是 odoo 的新手，我想要做的是，我想减去从 license_renewal_date = (2021,6,6) 开始的 90 天的 datetime.timedelta(days = 90) 怎么做，但是当我尝试时，我得到了这个以下错误

before_90_days = datetime.datetime.now().date() - datetime.timedelta(days = 90)
datetime.date(2020, 3, 11)

license_renewal_date = (2021,6,6)

exp_90_days = license_renewal_date - datetime.timedelta(days = 90)

错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for -: 'tuple' and 'datetime.timedelta'

在 Odoo py 文件中：

license_renewal_date = fields.Date("Renewal Date",track_visibility='onchange')

def exp_date1(self):
    before_90_days = datetime.datetime.now().date()- datetime.timedelta(days = 90)
    exp_90days = self.env['(crm.lead.extended)'].search([('(license_renewal_date)','=',before_90_days)])
    template = self.env.ref('crm_extended.create_crm_lead_mail_template')
    template.send_mail(rec.id, force_send=True)   

更新：我有更新仍然得到同样的错误有人帮我解决他的问题

@ api.multi
def exp_date1 (self):

    testDateOnly = license_renewal_date.date;

    before_90_days = testDateOnly - datetime.timedelta (days = 90)

    # before_90_days = datetime.datetime.now (). date () - datetime.timedelta (days = 90)

    exp_90days = self.env ['(crm.lead.extended)']. search ([('(license_renewal_date)', '=', before_90_days)])

    template = self.env.ref ('crm_extended.create_crm_lead_mail_template')

    template.send_mail (self.id, force_send = True)

您不能datetime仅使用元组创建对象(2021,6,6)

 license_renewal_date = (2021,6,6)

你必须为此使用datetime对象

 license_renewal_date = datetime.datetime(2021, 6, 6).date()

这都是你的问题。

现在它可以正常工作了：

import datetime

before_90_days = datetime.datetime.now().date() - datetime.timedelta(days=90)

print(before_90_days)

license_renewal_date = datetime.datetime(2021, 6, 6).date()

exp_90_days = license_renewal_date - datetime.timedelta(days=90)

print(exp_90_days)
