- """ PLEASE NOTE! I just realized that I need to have a __str__ method on User
- to get it to write the usernames back in the form when it redisplays them, since
- this validator turns them into user objects instead. This fact actually sounds dangerous
- to me in the future, since it means I proably shouldn't be changing the data input
- by the user right here in the validator, or the user will see the post-mangled data instead
- of what they actually typed. Hm.
-
- One solution to this could be to only look up the users after normal validation is over,
- and then manually add validation errors to the form if that fails. But I think that kind of
- sucks. Perhaps the ideology in Formish, where they keep Validation and Conversion as
- separate tasks, is a better way of doing it? That way there is less risk of changing the user's
- input -- you do that at the conversiot stage -- yet it is still encapsulated in the form workflow.
- Hm. But that means I'd have to query for the users in the validation step and throw them away,
- or something equally stupid. Guess there's no perfect solution here, but I thought it was
- worth discussing.
-
- Btw, this is meant to be used by a field with multi user autocompletion on it (like on stackoverflow tags),
- so the user should never actually submit anything invalid unless they disable javascript and force it.
