See All Options

Creates an alias between a single attribute's validations to another. This copies all messages, errors, etc., to the current attribute as well as its validation state (isValid, isValidating, etc.)

Examples

validator('alias', 'attribute')
validator('alias', {
  alias: 'attribute',
  firstMessageOnly: true
})

Normalized options passed in.

validator('alias', 'attribute')
  // Becomes
  validator('alias', {
    alias: 'attribute'
  })
  

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. `javascript 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:

  • type String
    The type of message template to use
  • value Mixed
    Current value being evaluated
  • options Object
    Validator built and processed options (used as the message string context)

Returns:

String: The generated message
getValue () Mixed private
Wrapper method to value that passes the necessary parameters

Returns:

Mixed: value
