Validates that the attributes’ values are not included in a given list. All comparisons are done using strict equality so type matters! For range, the value type is checked against both lower and upper bounds for type equality.
Examples:
validator('exclusion', {
in: ['Admin', 'Super Admin']
})
validator('exclusion', {
range: [0, 5] // Cannot be between 0 (inclusive) to 5 (inclusive)
})

Build options hook. Merges default options into options object. This method gets called on init and is the ideal place to normalize your options. The presence validator is a good example to checkout
Returns:

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'.
Parameters:
Returns:
The generated message
Wrapper method to value that passes the necessary parameters
