Re: Model user with pk 1L does not exist at Admin

What python version are you using, and with what django version.  Also, please show an example of what code you are using/typing to update/add a group.

Here is my model:

class UserSIMS(models.Model):

    TATA_USAHA = 0

    DOSEN = 1

    MAHASISWA = 2

    TYPE_CHOICES = ((TATA_USAHA, 'Tata Usaha'), (DOSEN, 'Dosen'), (MAHASISWA, 'Mahasiswa'))

    user = models.OneToOneField(User)

    type = models.IntegerField(choices=TYPE_CHOICES) # 0 = TU 1 = dosen 2 = mahasiswa

class Group(models.Model):

    name = models.CharField(max_length=100)

    lecturer = models.ForeignKey(User, null=True, blank=True, limit_choices_to={'usersims': UserSIMS.DOSEN})

    company = models.ForeignKey(Company, null=True, blank=True)

    tor = models.FileField(upload_to='tor', null=True, blank=True)

    logact = models.FileField(upload_to='logact', null=True, blank=True)

    document = models.FileField(upload_to='document', null=True, blank=True)

    created_at = models.DateTimeField(null=True, blank=True)

    updated_at = models.DateTimeField(null=True, blank=True)

    def save(self, *args, **kwargs):

        if not self.id:

            self.created_at = datetime.datetime.today()

        self.updated_at = datetime.datetime.today()

        super(Group, self).save(*args, **kwargs)

And this is my group admin model

class GroupAdmin(admin.ModelAdmin):

    list_display = ("name", "lecturer", "company")

    def formfield_for_foreignkey(self, db_field, request, **kwargs):

        if db_field.name == "lecturer":

            kwargs["queryset"] = User.objects.filter(usersims__type=UserSIMS.DOSEN)

        return super(GroupAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

admin.site.register(Group, GroupAdmin)

When i tried to update the group or add a new group, there are error like this "Model user with pk 1L does not exist". 

What should I do? Thanks in advance. :D
