1.服务记录(service)模块

1.1.models.py 设定

1.1.1.论次服务记录

当订单售出论次服务类商品，或是售出包含论次服务类商品的套盒类商品时，系统会自动抛一笔论次服务记录，当顾客来享受服务时，再用更新的方式完成该笔论次服务记录，并且在完成该笔服务记录时，系统会在自动抛一笔手工费用明细，记录哪家合作门店该支付给哪位员工多少手工费用。

class Cervice(models.Model):updated = models.DateTimeField(verbose_name='服务时间', null=True)order_detail = models.ForeignKey(OrderDetail, verbose_name='订单单身', on_delete=models.PROTECT)good = models.ForeignKey(Good, verbose_name='商品', on_delete=models.PROTECT)store = models.ForeignKey(Store, verbose_name='服务门店', on_delete=models.PROTECT)employee = models.ForeignKey(Employee, verbose_name='理疗师', on_delete=models.PROTECT,related_name='cervice_employee', null=True)customer = models.ForeignKey(Customer, verbose_name='顾客', on_delete=models.PROTECT)notes = models.CharField(max_length=64, blank=True, verbose_name='其他说明')created = models.DateTimeField(auto_now_add=True, verbose_name='建立时间')create_user = models.ForeignKey('auth.User', verbose_name='建立人员', on_delete=models.PROTECT,related_name='cervice_create_user')update_user = models.ForeignKey('auth.User', verbose_name='异动人员', on_delete=models.PROTECT,related_name='cervice_update_user', null=True)def __str__(self):return '{}'.format(self.pk)class Meta:verbose_name = '论次服务记录'verbose_name_plural = verbose_name

1.1.2.有效期间服务

同论次服务记录，当订单售出有效期间服务类商品，或是售出包含有效期间服务类商品的套盒类商品时，系统会自动抛一笔有效期间服务。
有效期间服务的意思是在一段时间内，顾客可以不限次数的来店享受该项服务，用订单售出有效期间服务类商品后，要先开卡，才会开始计算时间。

class Pervice(models.Model):created = models.DateTimeField(verbose_name='建立时间', default=datetime.now())order_detail = models.ForeignKey(OrderDetail, verbose_name='订单单身', on_delete=models.PROTECT)good = models.ForeignKey(Good, verbose_name='商品', on_delete=models.PROTECT)start_date = models.DateField(verbose_name='有效时间起', blank=True, null=True)end_date = models.DateField(verbose_name='有效时间讫', blank=True, null=True)customer = models.ForeignKey(Customer, verbose_name='顾客', on_delete=models.PROTECT)create_user = models.ForeignKey('auth.User', verbose_name='建立人员', on_delete=models.PROTECT,related_name='pervice_create_user')updated = models.DateTimeField(verbose_name='异动时间', null=True)update_user = models.ForeignKey('auth.User', verbose_name='异动人员', on_delete=models.PROTECT,related_name='pervice_update_user', null=True)def __str__(self):return '{}'.format(self.pk)class Meta:verbose_name = '有效期间服务'verbose_name_plural = verbose_namepermissions = (('active_pervice', '开卡权限'),)

1.1.3.有效期间服务记录

有效期间服务与有效期间服务记录的差别是，有效期间服务记录的是顾客购买了哪项服务商品，而有效期间服务记录则是记录顾客来享受服务的相关数据。

class PerviceDetail(models.Model):pervice = models.ForeignKey(Pervice, verbose_name='有效期间服务', on_delete=models.PROTECT)store = models.ForeignKey(Store, verbose_name='服务门店', on_delete=models.PROTECT)employee = models.ForeignKey(Employee, verbose_name='理疗师', on_delete=models.PROTECT,related_name='pervicedetail_employee')notes = models.CharField(max_length=64, blank=True, verbose_name='其他说明')created = models.DateTimeField(auto_now_add=True, verbose_name='服务时间')create_user = models.ForeignKey('auth.User', verbose_name='建立人员', on_delete=models.PROTECT,related_name='pervicedetail_create_user')updated = models.DateTimeField(verbose_name='异动时间', null=True)update_user = models.ForeignKey('auth.User', verbose_name='异动人员', on_delete=models.PROTECT,related_name='pervicedetail_update_user', null=True)def __str__(self):return '{}'.format(self.pk)class Meta:verbose_name = '有效期间服务记录'verbose_name_plural = verbose_name

在顾客来享受服务之后，可以把论次服务记录打印成纸本让顾客签名保存。

1.2.3.PerviceDetailAdmin呈现画面

当登入人员在PerviceAdmin新增单身的有效期间服务记录后，再到这里来打印纸本让顾客签名，因此add/change/delete权限都是关闭的。

1.3.urls.py 设定

打印论次服务记录与有效期间服务记录会用到的url设定。

app_name = 'service'urlpatterns = [path('cervice/<int:id>/download/', views.download_cervice_page, name='download_cervice_page'),path('pervice_detail/<int:id>/download/', views.download_pervice_detail_page, name='download_pervice_detail_page'),

1.4.views.py 设定

urls.py对应的功能实作。
