buildOptions
(
  • options
  • defaultOptions
  • globalOptions
)
Object

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

Parameters:

Returns:

createErrorMessage
(
  • type
  • value
  • options
)
String

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'.
