[英]Verify a Django model field inside a Django model
我有一个名为Attendance的Django模型,该模型具有雇员的进场时间和进场时间以及该条目的状态,以查看其是否被授权。 然后,我正在制作另一个称为薪资的模型。 我希望它可以检查“出勤”条目内部以查看所有“授权”条目,然后对它们进行一些操作。 如何检查出勤中所有条目的所有状态字段?
编辑:更新以更好地阐述我的问题。
为了更好地阐述我的问题,这是我如何设置出勤模式:
class CWorkAttendance(models.Model):
AUTO_ATT = "AU"
MANUAL_ATT = "MA"
WORK_ENTRY_TYPES = (
(AUTO_ATT, "Auto-Attendance"),
(MANUAL_ATT, "Manual-Attendance"),
)
AUTHORIZED = "AU"
UNAUTHORIZED = "UA"
WORK_ENTRY_STATUSES = (
(AUTHORIZED, "Athorized"),
(UNAUTHORIZED, "Un-Authorized"),
)
#Thank you motatoes
def face_locations_in(self, instance):
now = datetime.datetime.now()
return "attendance/{}/{}/in".format(instance.work_employee, now.strftime("%Y/%m/%d"))
def face_locations_out(self, instance):
now = datetime.datetime.now()
return "attendance/{}/{}/out".format(instance.work_employee, now.strftime("%Y/%m/%d"))
work_employee = models.ForeignKey('CEmployees', on_delete=models.CASCADE,)
work_start_time = models.DateTimeField()
work_end_time = models.DateTimeField(null=True)
work_duration = models.IntegerField(null=True)
work_entry_type = models.CharField(max_length=2,choices=WORK_ENTRY_TYPES)
work_entry_status = models.CharField(max_length=2, choices=WORK_ENTRY_STATUSES, default=WORK_ENTRY_STATUSES[1][0])
employee_face_captured_in = models.ImageField(upload_to=face_locations_in,)#////////
employee_face_captured_out = models.ImageField(upload_to=face_locations_out,)
如果您仔细查看work_entry_status
,则选择CharField它将包含条目的状态(默认情况下为work_entry_status
)。
我想创建一个薪资模型,该模型将检查CWorkAttendance
模型中的所有行,并检查其work_entry_status
字段以查看它们是否已被授权,这就是我想学习的方法。
如果这些字段被授权,我想从雇员的原始CEmployees
行中获取行的work_employee
, work_duration
以及一些详细信息。
这是我希望我的薪资单/薪资模型看起来像这样:
class Payslip(models.Model):
GENERATED = "GEN"
CONFIRMED = "CON"
PAYSLIP_STATUS = (
(GENERATED, "Generated-UNSAVED"),
(CONFIRMED, "Confirmed-SAVED"),
)
payslip_number = models.IntegerField()#MM/YY/AUTO_GENERATED_NUMBER(AUTO_INCREMENT)
payslip_employee = models.ForeignKey('CEmployees', on_delete=models.CASCADE,)#Choose the employee from the master table CEmployees
payslip_generation_date = models.DateTimeField(default=datetime.datetime.now())#Date of the payroll generation
payslip_total_hours = models.IntegerField()#Total hours that the employee worked
payslip_from_date = models.DateField()"""The date from when the payslip will be made. The payslip will be manual for now, so generate it after choosing a a date to generate from."""
payslip_total_basic_seconds = models.IntegerField()#Total seconds the employee worked
payslip_total_ot_seconds = models.IntegerField()#Total overtime seconds the employee worked
payslip_basic_hourly_rate = models.IntegerField()#The basic hourly rate of the employee mentioned here. Take from the master employees table.
payslip_basic_ot_rate = models.IntegerField()#Taking the basic overtime rate from the master table
payslip_total_amount = models.FloatField()#The total amount of the payslip
payslip_entry_status = models.CharField(max_length=3, default=GENERATED)#The status of the pay slip.
谢谢,
不知道我是否很好地理解了您的要求,所以如果我误解了,请告诉我。
# `employee` is the work_employee in question
# if you don't want to filter by employee, remove `work_employee=employee`
attendances = CWorkAttendance.objects.filter(work_entry_status=CWorkAttendance.AUTHORIZED, work_employee=employee)
for attendances in attendances:
# do things with this attendance record
attendance.work_duration
attendance.employee
# ....
由于您希望手动进行操作,因此建议您使用一个单独的视图来生成薪资单。 重要的是要知道此工资单的date_from
和date_to
。 我想象是经理将有权访问此视图,因此您需要为其设置适当的访问控制。 我还认为,即使要在当前日期之前生成它,也需要有一个payslip_to_date
,这对于保存记录很有用。 我假设您在下面的代码中有该列。
views.py:
from django.views import View
class GeneratePayslip(View):
"""
make sure you have the right access controls set to this view
"""
def post(self, request, **kwargs):
employee_id = kwags.POST.get("employee_id")
date_from = kwargs.POST.get("from_date")
date_to = kwargs.POST.get("to_date")
# we fetch all the objects within range
attendances = CWorkAttendance.objects.filter( \
work_entry_status=CWorkAttendance.AUTHORIZED, \
work_employee_id=employee_id, \
work_start_time__gte=date_from, \
work_end_time__lte=date_to \
)
hours = 0
for attendance in attendances:
# perform calculations to compute total sum and rate
pass
# create the payslip object here ..
# redirect to a success page and return
如果您想稍后自动执行此操作,则可能希望每月一次自动生成工资单。 为此,您可以使用Celery之类的方法让每位员工在后台运行定期任务。 如果是这种情况,您可以将上面的代码移动到utils.py
的文件中。 您可以创建一个使用employee_id,from_date,to_date的方法,然后生成payslip对象,将payslip_id返回给调用方法
