- A motherfucking django model field to bring
base64
encoded key to models. - It uses
base64
fromdjango.utils.baseconv
for encoding. - Tested on Python2.7, Python3.3 .
Base64Field
is useful where you need a base64 encoded value from model's Primary Key a.k.a PK which is available on every django application model by default. Sine base64 encoder works with integer value then PK should be also integer, Fortunately again PK field is integer by nature.
When a model gets saved, post_save
signal will be emitted, This is where a base64
encoded key will be generated/encoded from model's PK
, Then model will gets updated not getting save again. this operation happens just on the first time model gets saved. In next time model gets saved or updated base64
won't be generated.
You wanna know more about how django-base64field
works? Then get da fuck out of README.rst
and look inside the django_base64field.tests.py
.
Here is simple usage of Base64Field
:: >>> from django.db import models >>> from django_base64field.fields import Base64Field >>> >>> class MyModelianto(models.Model): >>> ek = Base64Field() >>> >>> modelia = MyModelianto.objects.create(pk=314159265358979323) >>> modelia.ek >>> u'' >>> refreshed_modelia = MyModelianto.objects.get(pk=modelia.pk) >>> refreshed_modelia.ek >>> u'HS7Y_sdg3x'
As You can see ek
in not available on returned instance from MyModelianto.objects.create()
, It will be available after retrieving refreshed_modelia
from database which is same record as modelia
here.
This behavior can be easily controlled with implementing a simple helper method on MyModelianto
. You can find out more about this solution on django_base64field.tests.py
, Which it doesn't require to retrieving the instance from database after first creation just for getting ek` field. Installation ------------
