django-iban

Validated Django model fields for International Bank Account Numbers (IBAN - ISO 13616-1:2007) and SWIFT-BIC (ISO 9362:2009).

Author: Ben Konrath

Features:

• Support for all currently active and planned to be active IBAN countries / numbers.
• Optional validation for IBANs included the Nordea IBAN extensions.
• Validates IBAN using the official validation algorithm.
• Basic validation for SWIFT-BIC.
• Python 3.2 and 3.3 support for Django >= 1.5.

Usage:

Use the model fields IBANField and/or SWIFTBICField in your models:

from django.db import models
from django_iban.fields import IBANField, SWIFTBICField


class CustomerModel(models.Model):
    iban = IBANField()
    swift_bic = SWIFTBICField()

Use the form fields IBANFormField and/or SWIFTBICFormField in your forms:

from django import forms
from django_iban.forms import IBANFormField, SWIFTBICFormField


class CustomerForm(forms.Form):
    iban = IBANFormField()
    swift_bic = SWIFTBICFormField()

If you want to validate the Nordea IBAN extensions, the model and form fields can be setup like this:

class CustomerModel(models.Model):
    iban = IBANField(use_nordea_extensions=True)


class CustomerForm(forms.Form):
    iban = IBANFormField(use_nordea_extensions=True)

Development:

Coding style: PEP8 with 120 character lines.

Ideas for new features include:

• SWIFT-BIC validation using referenced IBANField (SEPA requires both IBAN and SWIFT-BIC to be correct).
• Translation of validation error messages using Transifex.
