Validates the associated casted model. This method should not be used within your code as it is automatically included when a CastedModel is used inside the model.

Validates if the field is unique for this type of document. Automatically creates a view if one does not already exist and performs a search for all matching documents.

Example:

  class Person < CouchRest::Model::Base
    property :title, String

    validates_uniqueness_of :title
  end

Asside from the standard options, you can specify the name of the view you‘d like to use for the search inside the +:view+ option. The following example would search for the code in side the all view, useful for when unique_id is used and you‘d like to check before receiving a RestClient Conflict error:

  validates_uniqueness_of :code, :view => 'all'

A +:proxy+ parameter is also accepted if you would like to call a method on the document on which the view should be performed.

For Example:

  # Same as not including proxy:
  validates_uniqueness_of :title, :proxy => 'class'

  # Person#company.people provides a proxy object for people
  validates_uniqueness_of :title, :proxy => 'company.people'
