About django, each user information save to database

Question

I want to save the database attendance data daily of each user,

but my no error no saved why? please help me this is my full code below:

this is my views.py:

def staffs(request):
    args = {}
    args.update(csrf(request))
    args['staffs'] = User.objects.all()
    return render_to_response("staffs.html", args)

def staffdetail(request, user_id=1):
    user = get_object_or_404(User, pk=user_id)
    return render_to_response("staffdetail.html",
                         {"user": User.objects.get(id=user_id) })

def attendance(request, user_id):
    if request.method == "POST":
        attendance = Attendance_data(user = request.user.id)
        form = AttendancekForm(request.POST, instance = attendance)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/articles/get/%s' % user.id)
    else:
        form = AttendanceForm()
    return render_to_response('attendance.html', context_instance = RequestContext(request, {'form': form}))

def leave_work(request, user_id):
    if request.method == "POST":
        leave_work = Leave_work(user = request.user.id)
        form = Leave_workForm(request.POST, instance = leave_work)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/articles/get/%s' % user.id)
    else:
        form = Leave_workForm()

    last_kana  = models.CharField(max_length=255)
    employee_number = models.CharField(blank=True, max_length=22)
    created_at = models.DateTimeField(auto_now_add=True)

    def __unicode__(self):
        return self.user_name

class Attendance_data(models.Model):
    user_name = models.CharField(max_length=255)
    employee_number = models.CharField(blank=True)

    def __unicode__(self):
        return self.user_name, employee_number

class Leave_work(models.Model):
    user_name = models.CharField(max_length=255)
    employee_number = models.CharField(blank=True, max_length=22)

    def __unicode__(self):
        return self.user_name, employee_unmber

class ArticleForm(forms.ModelForm):

    class Meta:
        model = User
        fields = ('user_name','first_kana', 'last_kana', 'employee_number')
    user_name = forms.CharField( label="name",error_messages={'required': ''})
    first_kana = forms.CharField(label="firstname",error_messages={'required': ''})
    last_kana = forms.CharField(label="lastname",error_messages={'required': ''})
    employee_number = forms.CharField(label="number", required=False)

class Attendance_dataForm(forms.ModelForm):

    class Meta:
        model = Attendance_data
        fields = ('user_name','employee_number')

You are doing a lot of wrong thing in your views. If you look at your model Attendence_data, it has two fields user_name and employee_number. so its constructor would accept two arguments, user_name and employee_number or any other fields that are set not to be NULL and have no default value, so passing request.user.id to the its constructor would not make it a valid object. Same is the case with Leave_work model. So if you need to do this, you need to overload the default constructor. But seems like you are not being able to understand the basic concepts of how Django works so I'd suggest you to go trough this tutorial as this will clear a lot of basic concepts.

and what is the argument work that you are passing to the instance parameter of the AttendenceForm constructor.

>>form = AttendancekForm(request.POST, instance = work) this is a mistake to write, It was corrected to attendance, but can not be saved
