[web2py] Re: requires questions

[niknok]

Thanks for the suggestion. I tried it but I was unable to make use of
it. Your suggestion did force me to rethink the design so I discarded
the full IS_MATCH  string(can't even remember why I went for that),
and simply kept the expression string itself (i.e. '^\\d{3}-\\d{4}-\
\d{4}-\\d{1}?$')

And now it works and looks much cleaner without eval() ...

requires=[IS_MATCH(str(db.agency[int(request.vars.issuer or
1)].regex)),CRYPT(auth.settings.hmac_key),IS_NOT_IN_DB(db,'card.id_number')]

Thanks

Maybe the IS_EXPR() validator?

IS_EXPR
IS_EXPR

Its first argument is a string containing a logical expression in terms of a 
variable value. It validates a field value if the expression evaluates to 
True. For example:

1.
2.

requires = IS_EXPR 
('int(value)%3==0',
   error_message=T 
('not divisible by 3'))
