[Cppcms-users] Reporting validation failure reasons back to users

[doug l. <bi...@gm...>]

Hi -- I was just wondering if there's a mechanism for reporting detailed
form validation failure reasons back to the user?
I've been digging around in the tutorials and API docs & haven't found one.
The tutorial on forms shows how to set up validation on a form, but that
form just redisplays if the validation fails.
In RoR, validation also adds errors to a collection whenever a validation
constraint fails.
Is there something like this in cppcms, or is this something the framework
user should implement themself?
If so, is there a recommended way of reporting validation errors back to
the user?
Thanks,
   Doug.

Ah, brilliant, cheers!
So are those ever set automagically by constraints set on widgets (like
range()), or does the developer set those?
& thanks very much for your help.

No, you must set it your self. So when you have range(5,10), you set your
error_message to something like "Minimum 5, Maximum 10". If you want to
automate it, you have to write it your self. That should be pretty easy
though
