我有一个视图，单击该视图即可接受请假并完成这两件事。 扣除申请的叶子数量。如果只有1位用户，则该代码可以正常工作，但是一旦添加了另一位用户，该代码就会发疯。
我尝试了以下方法，但是没有运气
form = Leave_Form(request.POST or None)
if form.is_valid():
abc = form.save(commit=False)
abc.employee_leaves = request.user.employee
abc.save()
form = Leave_Form
# context = {'employee': employee, 'form': form}
context = {'form': form}
return render(request, 'projectfiles/reqleave.html', context)
def accept_leave(request,id): # accept email
all_item = Leave.objects.get(id=id)
employee = Employee.objects.get(id=id)
context = {'employee': employee, 'all_item': all_item}
leave = employee.leave_set.last()
#Annual Leave
if leave.leave_Type == 'Annual_leave':
employee.Annual_leave -= leave.leave_qty
leave_status = "Accepted"
employee.save()
#other conditions are here as well
else:
subject = "Leave Accepted" # email subject
email_from = "settings.EMAIL_HOST_USER" # email from
to_email = ['talhamurtaza@clickmail.info'] # email to
with open("C:/Users/Bitswits 3/Desktop/Intern Work/LMS/LMS/projectfiles/templates/projectfiles/email/accept_email.txt", 'rb') as f:
msgbody = f.read()
msg = EmailMultiAlternatives(
subject=subject, body=msgbody, from_email=email_from,to=to_email)
html_template = get_template("...").render()
msg.attach_alternative(html_template, "text/html")
msg.send()
return render(request, 'projectfiles/email.html', context)
def reject_leave(request, id): # reject email
all_item = Leave.objects.get(id=id)
all_item.leave_status = "Rejected"
all_item.save()
context = {'all_item':all_item}
subject = "Leave Rejected" # email subject
email_from = "settings.EMAIL_HOST_USER" # email from
to_email = ['talhamurtaza@clickmail.info'] # email to
with open(
"C:/Users/Bitswits 3/Desktop/Intern Work/LMS/LMS/projectfiles/templates/projectfiles/email/reject_email.txt", 'rb') as f:
msgbody = f.read()
msg = EmailMultiAlternatives(
subject=subject, body=msgbody, from_email=email_from, to=to_email)
html_template = get_template(
"C:/Users/Bitswits 3/Desktop/Intern Work/LMS/LMS/projectfiles/templates/projectfiles/email/reject_email.html").render()
msg.attach_alternative(html_template, "text/html")
msg.send()
return render(request, 'projectfiles/rejectemail.html',context)
但是我无法这样做，它给我URL错误和查看错误/ 例如 1. accept_leave（）恰好接受2个参数（给定1个） 2. quereyset不存在 3.没有匹配的querey等

我希望代码将状态更改为“已接受”，并扣除所选的请假金额并在db中为申请请假的用户更新。
