Odoo 13：通过创建功能创建多个记录

Question

这是我在 Odoo13 中编写的第一个创建函数。我想得到 begin_date 和 end_date 两个日期之间的时间段，日期应保存在列表中。从这个列表中，我想为列表中的每一天为单个员工创建记录。但我的代码似乎不正确，我收到这种错误：AttributeError: 'NoneType' object has no attribute 'id'

这是我的代码：

from datetime import timedelta, datetime, date
from calendar import monthrange


from odoo import api, fields, models, tools
from odoo.exceptions import UserError, AccessError, ValidationError
from odoo.tools import date_utils


class TimeOff(models.Model):
    _name = 'project.timeoff'
    _rec_name = 'employ_id'

    employ_id = fields.Many2one('hr.employee', string='Employee', required='1')

    date = fields.Date('Date', required=True, index=True,
                       default=fields.Date.context_today)

    begin_date = fields.Datetime(
        'First Day of Leave', required='1')

    day_hours = fields.Integer('Off hours per day', default='8', required='1')
    end_date = fields.Datetime(
        'Last Day of Leave')

###### create function #######
    @api.model
    def create(self, vals):
        range_date = []    # empty list
        if self.employ_id: # check if field has value
            if self.begin_date and self.end_date: # check if field has value
                range_date = self.calc_dates(
                    self.begin_date, self.end_date, mode='date') # call custom function and expect a list to be returned
                if range_date is None:
                    raise ValidationError("Something went wrong") # list is empty
                else: # iterate through list and create record for each date 
                    for day in range_date:
                        vals = {
                            'employ_id': self.employ_id,
                            'begin_date': day}
                        return super(TimeOff, self).create(vals)

### custom function to get all dates between begin_date and end_date #####

    def calc_dates(self, date1, date2, mode='date'):
        date_from = fields.Date.from_string(date1)
        date_to = fields.Date.from_string(date2)

        delta = date_to - date_from

        if delta.days < 0: 
            return None

        dates = []

        for n in range(delta.days + 1):
            if mode == 'date':  # returns dates as date format
                dates.append(date_from + timedelta(days=n))
            if mode == 'string': # returns dates as string format
                dates.append(fields.Date.to_string(
                    date_from + timedelta(days=n)))
        return dates

所以当我按下创建时，我得到了这个错误：

    return result.id if isinstance(args[0], Mapping) else result.ids

要么我不能在这个问题中使用 self 要么返回有问题

对于遇到相同问题并希望自动创建记录的每个人，这是我的解决方案：

from datetime import timedelta, datetime, date
from calendar import monthrange


from odoo import api, fields, models, tools
from odoo.exceptions import UserError, AccessError, ValidationError
from odoo.tools import date_utils


class TimeOff(models.Model):
    _name = 'project.timeoff'
    _rec_name = 'employ_id'

    employ_id = fields.Many2one('hr.employee', string='Employee', required='1')

    date = fields.Date('Date', required=True, index=True,
                       default=fields.Date.context_today)

    begin_date = fields.Datetime(
        'First Day of Leave', required='1')

    day_hours = fields.Integer('Off hours per day', default='8', required='1')
    end_date = fields.Datetime(
        'Last Day of Leave')
############################################ create um zw periode von datum, records zu erstellen ##############################################

    def update_record(self):
        range_date = []
        for rec in self:
            if rec.employ_id:
                if rec.begin_date and rec.end_date:
                    range_date = rec.calc_dates(
                        rec.begin_date, rec.end_date)
                    if range_date is None:
                        raise ValidationError("Something went wrong")
                    else:
                        for day in range_date:
                            val = {
                                'employ_id': rec.employ_id.id,
                                'begin_date': day}
                            self.create(val)
                            self._cr.commit()


################################################### funktion um periode mit datum zw begin und end_date auzugeben (als liste) ########################################################################


    def calc_dates(self, date1, date2):
        date_from = date1
        date_to = date2

        delta = date_to - date_from

        if delta.days < 0:
            return None

        dates = []

        for n in range(delta.days + 1):
            dates.append(date_from + timedelta(days=n))

        return dates 

不要忘记创建自定义按钮并调用函数：

  <record id="project_timeoff_tree_view" model="ir.ui.view">
          <field name="name">view.project.timeoff.tree</field>
          <field name="model">project.timeoff</field>
          <field name="arch" type="xml">
            <tree string="TimeOff">
              <field name="employ_id" string="Employee"/>
              <field name="begin_date"/>
              <field name="end_date"/> 
              <field name="day_hours"/>
              <!-- <field name="requested_hours"/> -->
              <button name="update_record" string="Update" class="btn-primary" type="object" />
            </tree>
          </field>
  </record>

PS：树形视图中每条记录后都会显示该按钮，我还没有找到将其放在标题中的解决方案

由于self是一个空记录集，self.employ_id将被评估为False，Odoo不会执行if语句，然后将返回默认值None。

您可以使用 val 列表调用 super（不返回结果），但这会改变 create 方法的行为，它应该从 vals 变为 return the created record。

您可以使用向导创建project.timeoff 记录。
