Good afternoon friends I have a slight problem, and I do not see the solution, I'm trying to save a search value by rank of fronts in the database using a form, all right, but when I try to save it gives me this error :

'FiltroFechas' object has no attribute 'save'

I've seen some solutions and it's changing the class in form.py to ModelForm but I really do not want to use a model but my own form

I leave you my view.py and my template, thanks in advance

view.py

def inicio(request):
    plan_gral = jovenclub.objects.aggregate(sum=Sum('plan_gral'))
    juridic_gral = ingresos.objects.aggregate(sum=Sum('juridico'))
    natural_gral = ingresos.objects.aggregate(sum=Sum('natural'))
    general = juridic_gral['sum']+natural_gral['sum']
    porciento_general = general*100/plan_gral['sum']
    ingreso = ingresos.objects.all()
    if request.method == "POST":
        formulario = FiltroFechas(request.POST)
        if formulario.is_valid():
            consulta = formulario.save(commit=False)
            consulta.hasta = timezone.now()
            consulta.save()
    else:
        formulario = FiltroFechas()
        args = {}
        args.update(csrf(request))
        args['form'] = formulario
    return render_to_response('index.html', {'form': formulario, 'porciento':porciento_general, 'general':general, 'plan_gral':plan_gral,'suma':plan_gral['sum'],'juridico':juridic_gral['sum'], 'ingreso':ingreso, 'natural':natural_gral['sum']}, context_instance=RequestContext(request))

index.html

<form action="" method="POST"> {% csrf_token %}
Desde:{{ form.desde }}&nbsp;&nbsp; Hasta:{{ form.hasta }}<br/>
<input  type = "submit" name = "submit" value = "Ver resultados">
</form>

Form.py

# encoding:utf-8 
from django.forms import ModelForm
from django import forms
from principal.models import jovenclub
from functools import partial
DateInput = partial(forms.DateInput, {'class':'form-control bs-datepicker'})

class FiltroFechas(forms.Form):
    desde = forms.DateField(widget=DateInput())
    hasta = forms.DateField(widget=DateInput())

python django

I do not understand where you want to "save" , but there is something that is clear:

Class forms.Form inherits its properties and methods from two classes:

DeclarativeFieldsMetaclass - used to obtain the fields that will be used in the form, and
BaseForm - which contains the most basic logic of the Django forms. This class provides, among others, the following methods: order_fields , is_valid , add_prefix , as_table , as_ul , as_p . You can check the source code at this address .

What I'm going to do is that, effectively, the class FiltroFechas does not have any method save() where to store the values.

Alternatives

If you add the changes to your model, you can save them.
Save them to a text file on your server.
Save them in the browser's localStorage.
