|
|
* This class provides methods that add validation cababilities to models.
|
2015-03-05 01:21:25 +00:00
|
|
|
* Each of the validations runs when the `obj.isValid()` method is called.

|
|
|
* All of the methods have an options object parameter that has a
|
|
|
|
* `message` property. When there is only a single error message, this property is just a string;
|
|
|
|
* for example: `Post.validatesPresenceOf('title', { message: 'can not be blank' });`

|
|
|
*
|
2015-03-05 01:21:25 +00:00
|
|
|
* In more complicated cases it can be a set of messages, for each possible error condition; for example:
|
2012-03-27 14:22:24 +00:00
|
|
|
* `User.validatesLengthOf('password', { min: 6, max: 20, message: {min: 'too short', max: 'too long'}});`
