python - 从 python 中的函数返回的问题在哪里？

Question

我不明白为什么函数在 python 中不返回，我的函数计算两个日期之间的天数(星期五和星期六)但它不返回。

这是我的代码:

# -*- coding: utf-8 -*-

import datetime
import calendar
calendar.setfirstweekday(calendar.SUNDAY)

from odoo import models, fields, api

class HrMission(models.Model):
    _name = "hr.employee.mission"
    _description = "hr mission"
    _inherit = "hr.employee.mission"

    days_compensation =fields.Float(compute='get_compensation', compstring='Jours de récupération', help="Jours de récupération si la mission contient les jours de repos",
                             required=True, readonly=True,)

    @api.multi
    @api.depends('mission_start_date', 'mission_end_date')
    def get_compensation(self):
        for rec in self:
            if rec.mission_start_date and rec.mission_end_date:
                time1 = datetime.datetime.strptime(rec.mission_start_date, "%Y-%m-%d")
                time2 = datetime.datetime.strptime(rec.mission_end_date, "%Y-%m-%d")
                week = {}
                leave_value = {}
        # Compute Number Of Friday And Saturday
                for i in range((time2 - time1).days):
                    day = calendar.day_name[(time1 + datetime.timedelta(days=i+1)).weekday()]
                    week[day] = week[day] + 1 if day in week else 1                    
                fri = week.get('Friday') if 'Friday' in week else 0  # Result Number 1 Of friday If "Start Date", "End date" --> "02/04/2019", "07/04/2019"
                sat = week.get('Saturday') if 'Saturday' in week else 0 # Same thing that Friday, Numbre 1 for Saturday
                friandsat = fri + sat # Result 2
                rec.days_compensation = friandsat

Answer 1

您需要将其显式放入您的 get_compensation() 函数中:

return friandsat

否则你的函数不知道它需要返回一些东西。
