Add Canadian (.ca) localflavor

Canadian postal code re pattern:

'^[A-Z]\d[A-Z] \d[A-Z]\d$'

Note: The RE is valid after normalizing the case to upper case and forcing a single space character between character groups).

Can you add a patch for this? i.e. add a new dir. in django.contrib.localflavor for ca and plug this into a "forms.py" file? - see one of the others for examples (e.g. AUPostCodeField in au/forms.py would be close)

Addition of .ca localflavor code

$ svn stat
A      ca
A      ca/ca_provinces.py
A      ca/__init__.py
A      ca/forms.py

See submitted patch for details.

Needs tests.

I think the regex used for postal codes is a little too generous. Here's what I'm using in my code :

'[ABCEGHJKLMNPRSTVXY]\d[A-Z] \d[A-Z]\d'

I don't think this is where I got it from, but it does seem to match : http://www.forta.com/blog/index.cfm?mode=entry&entry=A61BA033-3048-80A9-EFF8935E41AB9FE2

Addition of tests and modifications to .ca localflavor

Changed terminology "PostCode?" to "PostalCode?" to stay consistent with other localflavors Modified CAPostalCodeField regex as per cbrand's advice Modified CAPhoneNumberField to match USPhoneNumberField Added CASocialInsuranceNumberField Added CAProvinceField Added tests for CAPostalCodeField, CAPhoneNumberField, CAProvinceField, CAProvinceSelect, CASocialInsuranceNumberField

Forgot to do an svn add before the svn diff

The patch looks good. Let a core dev look at it and get it in!

(In [6202]) Fixed #3988: added a localflavor for our friends to the north (i.e. Canada). THanks, Tyler Tarabula.
