= Couchrest Uniqueness Validation
This is a simple add-on to {couchrest}[http://github.com/couchrest/couchrest] gem
Validates that the specified attribute is unique across documents with the same
couchrest-type using a view.
== Install
gem install couchrest-uniqueness-validation
== Usage
require 'rubygems'
require 'couchrest'
require 'couchrest-uniqueness-validation'
class User < CouchRest::ExtendedDocument
include CouchRest::Validation
property :nickname
property :login
view_by :nickname
# assumes that a view :by_nickname is present
validates_uniqueness_of :nickname
# uses a different from default view
validates_uniqueness_of :login, :view => 'my_custom_view'
# a call to valid? will return false unless no other document exists with
# the same couchrest-type, nickname and login
end
Note: at least two views should exist in the User design doc for this example to work -
:by_nickname and :my_custom_view.
See {CouchRest Views docs}[http://rdoc.info/rdoc/couchrest/couchrest/blob/1b34fe4b60694683e98866a51c2109c1885f7e42/CouchRest/Mixins/Views/ClassMethods.html#view_by-instance_method]
for more info on views.
== Note on Patches/Pull Requests
* Fork the {project}[http://github.com/crhym3/couchrest-uniqueness-validation].
* Make your feature addition or bug fix.
* Add tests for it. This is important so I don't break it in a
future version unintentionally.
* Commit, do not mess with rakefile, version, or history.
(if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
* Send me a pull request. Bonus points for topic branches.
