Introduction

This module provides a custom field for storing month (YYYY-MM) as a django field.

This can be useful when dealing with data that relates to a whole month, for example, the total expenditure for a given month.

This module also adds some arithmetic and other functionality for dealing with months.

Usage

Adding a month field to a django model:

from django.db import models
from month.models import MonthField


# Create your models here.

class ExampleModel(models.Model):
    name = models.CharField(max_length=20, blank=True)
    month = MonthField("Month Value", help_text="some help...")

    def __unicode__(self):
        return unicode(self.month)

The module defines a “Month” class which is used to represent the MonthField attribute on the model. The “Month” class can also be used standalone without any django model.

Some examples of funcionality provided by the Month class:

import month

m = month.Month(2017, 3)

print(m)
>"2017-03"

print(m + 2)
>"2017-05"

print(m.last_day())
>"2017-03-31"

m2 = month.Month(2017, 7)

print(m > m2)
>"False"

print(m.range(m2))
>"[2017-03, 2017-04, 2017-05, 2017-06, 2017-07]"
