Hello web2py users : Validating if numbers or decimals are entered on a form seem to be very straight forward and easy enough ! whether it is a phone number or a US postal code : Like for example a US postal code would go like this :
requires = IS_MATCH('^\d{5}(-\d{4})?$',error_message='not a zip code') > > however, a Canadian postal code on the other hand is another story : a Canadian postal code is configured like this : Letter#Letter #Letter# an example would be : A1B 2C3, or A1B-2C3, or again A1B2C3 : All these 3 postal codes are the same and equivalent in the Canadian postal code scheme ! How would I go about validating such input into a field on a form in python / web2py ??? it seems that there is no easy simple way to do this ! ... is there a set of alphabetic characters only .... without numbers in python / web2py ? I only found alpha numeric characters that take numbers as characters !! and it is not what I want !! .. Please help ! thank you Don --
