Get modal data from Django

Question

I have a list of customers on the screen of the responsible person, in case he presses to deny the client, opens a modal with the field Reason for him to fill. I want to take what was typed in this field and save in the table Historico_profile in the database. However, it is not a form, as I do?

Also, I need to take to save also the denied customer id and that of the logged in responsible

py views.

def usuarios_autorizar(request, value=None, user_id=None):
    user = Perfil.objects.get(pk=request.user.id)
    title = "Usuarios nao autorizados"
    grupo_responsavel = Grupo.objects.filter(responsavel=user.id)
    usuarios = Perfil.objects.filter(grupos__in=grupo_responsavel, is_staff=False)
    context = {'lista_usuarios': usuarios}

    return render(request, 'usuarios_autorizar.html', context)
def negar(request, item_id):
    # para negar
    user = User.objects.get(id=item_id)
    user.is_staff = False
    user.save()
    # historico
    historico = Historico_Perfil.objects.create()
    quem = User.objects.get(id=item_id)
    print(quem.id)
    historico.usuario = quem.id
    historico.data = datetime.now()
    historico.acao = "Negado"
    historico.save()
    return redirect("/cadastro/quantities")

py.models

class Historico_Perfil(models.Model):
    acao = models.CharField(max_length=255)
    motivo = models.CharField(max_length=255, blank=True)
    data = models.DateField(default=datetime.now, blank=True)
    usuario = models.ForeignKey(User)
    responsavel = models.ForeignKey(User)
