Usage

Below is a simple example for usage with schemata and save:

 
var schemata = require('schemata')
  , createCropValidator = require('validity-cf-crop-integrity-validator')
  , crops = [ { name: 'Rectangle' } ]
 
  var requiredCrops = crops.map(function(crop) {
    return crop.name
  })
 
  var schema = schemata(
    { images:
      { type: Object
      , defaultValue: {}
      , validators:
        { all: [ createCropValidator(requiredCrops) ]
        }
      }
    }
  )

API

var validate = createUniqueValidator(Array: requiredCrops)

Create a validate function. requiredCrops should be an array of image crops that require selection.

validate(String:key, String:keyDisplayName, Object:object, Function:cb)

This is a validity compatible function, which in turn is used by schemata for schema validation.

The callback signature cb(err, errorMessage).

err is an Error object if something bad happened and null otherwise. errorMessage is a String if a validation error happened and undefined otherwise.
