Question

我不明白为什么函数不会在python中返回，我的函数会计算两个日期之间的天数（星期五和星期六），但不会返回

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
                return friandsat

Answer 1

您需要在该字段上分配值。例如， rec.days_compensation = float_number

@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 2

您必须在for循环之外在函数的开头和结尾定义friandsat：

def get_compensation(self):
    friandsat = 0
    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
    return friandsat

Answer 3

删除readonly属性，默认情况下，除非给出相反的指示，否则计算字段为只读。
使字段存储= True
更新代码

@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 rec.days_compensation = fri + sat # Result 2

为什么函数不返回值？
