Hi, I am glad to see the UUID field coming to 1.8
Bellow is how we do it now in 1.7.
The advantages:
- it only uses 21 chars (instead of 32)
- chars are safe for URLs
- uuid is created when default is called
I advocate to have the short websafe representation. What do you think?
code:
> def safe_uuid():
> return uuid.uuid4().bytes.encode('base64').rstrip('=\n').replace('/',
> '_')
>
> class UUIDField(CharField) :
> """
> UUIDField stored in 21 Chars
> Example: uuid = UUIDField(primary_key=True, editable=False)
> """
> description = "UUIDField stored in 21 Chars"
> def __init__(self, *args, **kwargs):
> kwargs['max_length'] = kwargs.get('max_length', 22 )
> kwargs['default'] = safe_uuid
> CharField.__init__(self, *args, **kwargs)
>
> def deconstruct(self):
> name, path, args, kwargs = super(UUIDField, self).deconstruct()
> return name, path, args, kwargs
