[FE-discuss] Can formencode raise invalid for some valid value:

[deepak v. <yes...@gm...>]

Hi all,

The subject of this email may not seems obvious to some people but I could
resist myself from being asked this question. Please accept my apologies:

My Question is:

Is there any any support to raise Invalid exception for some values when
validation them ?


For e.g.
Suppose I have to validate email using email validatior.
Then want to raise Invalid exception to some emails like:
no...@ex... some emails like these.


example:
*    from formencode import validators*
*    from formencode.api import Invalid*
*    invalid_emails = ['no...@ex... <no...@ex...>',
'bl...@gm... <bl...@gm...>']*
*    email = 'no...@ex... <no...@ex...>'*
*    try:*
*        email_validator = validators.Email(invalidate=invalid_emails)*
*        email_validator.to_python(email)*
*    except Invalid, e:*
*        logger.log("An Invalid Exception Occurred", e)*
*        raise e*

In the above code, this should raise Invalid exception the we try to
validate invalid_emails.
Do we have support for this in future release.

In order to achieve this I have to do something like this:
*    from formencode import validators*
*    from formencode.api import Invalid*
*    invalid_emails = ['no...@ex... <no...@ex...>',
'bl...@gm... <bl...@gm...>']*
*    email = 'no...@ex... <no...@ex...>'*
*    try:*
*        if email in invalid_emails:*
*             raise Invalid*
*        email_validator = validators.Email(invalidate=invalid_emails)*
*        email_validator.to_python(email)*
*    except Invalid, e:*
*        logger.log("An Invalid Exception Occurred", e)*
*        raise e*

But I have to do this for all validators.
