Used by all pre-defined validators to build an error message that is present
in validators/message or declared in your i18n solution.
If we extended our default messages to include uniqueUsername: '{username} already exists',
we can use this method to generate our error message.
validate(value, options) {
var exists = false;
get(options, 'description') = 'Username';
get(options, 'username') = value;
// check with server if username exists...
if(exists) {
return this.createErrorMessage('uniqueUsername', value, options);
}
return true;
}
If we input johndoe and that username already exists, the returned message would be 'johndoe already exists'.
