gisele-validation

Validation extension to Gisele model library

Adds validation capabilities to any Gisele.Model instances

Usage

var User = Gisele.Model.create({
    name: { type: String, required: true, minlength: 15 },
    age: { type: Number, min: 18 }
});
 
var bob = new User({
    name: 'Bob',
    age: 15
});
 
// runs the validation rules of each field
bob.$$.validate();
 
console.log(bob.$$invalid);
// true
 
console.log(bob.$$errors);
//  {
//     name: { minlength: true },
//     age: { min: true }
//  }
 

Validation of custom fields

New field types must implement a validate() method that either returns true (is valid) or an object with the validation errors.

In the builtin fields they are key/value pairs with the key being an error and the value being true, as same as bob.$$errors above.

Example:

 
class Foo() { }
 
class FooField extends Gisele.Field {
    parse(value) { return new Foo(value); }
 
    validate(value) {
        // any validation rule can be applied
        if (this.required && value instanceof Foo) {
            return { required: true };
        }
 
        return true;
    }
}
 
Gisele.Field.add(Foo, FooField);
