Couchrest Uniqueness Validation
This is a simple add-on to 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 for more info on views.
Note on Patches/Pull Requests
-
Fork the project.
-
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.
