[0.4] Keystone should use the Mongoose validate

I think it would be cool if keystone can make use of a field’s schema validate function that may be configured in the field. The issue with letting mongoose process it is that input values are all cleared upon a fail validation as well as auto focus of an invalid field does not work. For example:

    description: {
        type: Types.Html,
        validate: {
            validator: function(v) {
                    return (v && v.length > 0)
            },
            message: 'Please provide a description!'
        }
    },

keystone should check if a validate/validator is defined and make use of it so that it may address the issues above.

Is there ANY way to show a custom error message with the Mongoose validator?

I see no value in having KS swallow the validator. I prefer seeing an explicit mongoose validator, since I know what it does. The less API surface for Keystone the better, since it’s yet another thing less to a) maintain, document etc b) learn when starting out with KS. If it’s not a facade or adapter it’s not valuable IMO.

I.e. close this muthafucker! 😉 Close all the issues! MUHAHAHAAA Sorry, got a bit carried away.
