Display only days on django template

Question

I'm trying to display the difference between 2 giving dates on django, and i've managed to make it, but now i'm strugling to display only the days, without the time, is there any filter that i can use?

My html template:

<a href="{% url 'edit_contract' contract.id %}">
    {% if contract.status == 'PN'  %}
        {{ today |sub:contract.starting_date  }}
    {% else %}
        TODO
    {% endif %}
</a>

My view:

@login_required
def contract_list(request):
    contracts = Contract.objects.filter(user=request.user)
    total_contracts_value = Contract.objects.filter(user=request.user).aggregate(sum=Sum('value'))['sum'] or 0
    contracts_count = Contract.objects.filter(user=request.user).count()
    today = date.today()
    return render(request, 'list_contract.html', {'contracts': contracts,
                                                       'total_contracts_value': total_contracts_value,
                                                       'contracts_count': contracts_count, 'today':today})

My output:

Answer 1

Days since start is a property of your contract, so you could create an actual property in the Contract model

from datetime import date
from django.db import models

class Contract(models.Model):
    ...
    @property
    def days_since_start(self):
        today = date.today()
        result = today - self.start_date
        return result.days

then refer to the property in your template

    {% if contract.status == 'PN'  %}
            {{ contract.days_since_start }}
    {% else %}
