How to make django model choice field human readable

So I have django model choice field with months 

class EntrySummary(models.Model):

    JANUARY = '1'
    FEBRUARY = '2'
    MARCH = '3'
    APRIL = '4'
    MAY = '5'
    JUNE = '6'
    JULY = '7'
    AUGUST = '8'
    SEPTEMBER = '9'
    OCTOBER = '10'
    NOVEMBER = '11'
    DECEMBER = '12'

    MONTH_CHOICES = (
        (JANUARY, 'January'),
        (FEBRUARY, 'February'),
        (MARCH, 'March'),
        (APRIL, 'April'),
        (MAY, 'May'),
        (JUNE, 'June'),
        (JULY, 'July'),
        (AUGUST, 'August'),
        (SEPTEMBER, 'September'),
        (OCTOBER, 'October'),
        (NOVEMBER, 'November'),
        (DECEMBER, 'December'),
    )

    name = models.CharField(
        max_length=255
    )
    month = models.CharField(
       max_length=2,
       choices = MONTH_CHOICES,
       default=JANUARY,
    )

Views.py I render it 

def based_onmonth(request, *args, **kwargs):
    monthId = request.GET.get('month')
    monthEntry = EntrySummary.objects.filter(month=monthId)
    return render(request, 'app/js_templates/month_dropdown_list.html', {'MonthItem': monthId})

html template:

<option value="">---------</option>
{% for item in MonthItem %}
    <p>item.name</p>
<option value="{{ item }}">{{ item }}</option>
{% endfor %}

Doing this i receive {'month': '2'} in my select section

My question is how to print just 2 without month

Use the get_<field_name>_display mechanism:

# Return the right thing from your view.
return render(request, 'app/js_templates/month_dropdown_list.html', {'MonthItem': monthEntry})

and in your template:

{% for item in MonthItem %}
    <option value="{{ item.month }}">{{ item.get_month_display }}</option>
{% endfor %}

In your return you will want to send the monthEntry to the frontend:

return render(request, 'app/js_templates/month_dropdown_list.html', {'MonthItem': monthEntry})
