Convenient fields and classes for handling measurements
Project description
Easily use, manipulate, and store unit-aware measurement objects using Python and Django.
Note: Currently, this is not compatible with Django 1.6 or later. For more information, please follow the issue tracking this limitation.
django.contrib.gis.measure has these wonderful ‘Distance’ objects that can be used not only for storing a unit-aware distance measurement, but also for converting between different units and adding/subtracting these objects from one another.
This module provides for a django model field and admin interface for storing any measurements provided by python-measurement.
Example use with a model:
from django_measurement.fields import MeasurementField
from measurement.measures import Volume
from django.db.models import Model
class BeerConsumptionLogEntry(Model):
name = models.CharField(max_length=255)
volume = models.MeasurementField()
def __str__(self):
return '%s of %s' % (self.name, self.volume, )
entry = BeerConsumptionLogEntry()
entry.name = 'Bear Republic Racer 5'
entry.volume = Volume(us_pint=1)
entry.save()These stored measurement objects can be used in all of the usual ways supported by python-measurement too:
>>> from measurement.measures import Weight
>>> weight_1 = Weight(lb=125)
>>> weight_2 = Weight(kg=40)
>>> added_together = weight_1 + weight_2
>>> added_together
Weight(lb=213.184976807)
>>> added_together.kg # Maybe I actually need this value in kg?
