Unique: true validation rule #9

Hey there,

Thanks for the tutorials. I learned a lot about sails.js because of you.

Anyway, I'm confused with the unique: true model attribute for validation. It returns a different format than other validators like maxLength etc.. this is the error being returned by unique:true - MongoError: E11000 duplicate key error index: sails_twitter.user.$username_1 dup key: { : "ken" } while maxLength etc.. returns - { ValidationError: { password: [ [Object], [Object] ] } } . Because of that I can easily render the error messages for maxLength, minLength etc.. but having a hard time on how to display the error message for unique: true; rule because the error message is a different format.

Also, I can't see the unique rule in anchor.js w/c is used by waterline.js for validation - https://github.com/balderdashy/anchor/blob/master/lib/rules.js

is unique rule really supported?

Where did you find the unique attribute? it's not mention in the doku any more (i use it too and have problems thanks to your question i had a good idea, but i need the part again where the mentiont unique adapter attr.) looks like the removed it again?

If I'm not mistaken, the app level (validator - Anchor) doesn't really validate that the model attribute like username is unique, if unique: true is set, it validates in the database level like if you're using MongoDB it just creates a unique index to ensure that it will be unique, I think that's why it throws a different error message format.
