A simple Ruby on Rails plugin to let model auto do something (like strip, downcase, etc.) before validation.
Before validation do strip, in your model:
auto :strip, :for => :field
For many fields:
auto :strip, :for => [:field1, :field2, ...]
Before validation do substr (with one argument):
auto :, :with => 0...10, :for => :field_or_fields
Or if you want with more argument:
auto :, :with => [0, 10], :for => :field_or_fields
An example from spec:
class Item < ActiveRecord::Base auto :strip, :for => [:nickname, :email, :info] auto :downcase, :for => :email auto :, :with => 0...10, :for => :info # or auto :, :with => [0, 10], :for => :info end user = User.new(:nickname => ' ayaya ', :email => ' AYAYA@EXAMPLE.COM ', :info => ' hello world! ') user.valid? # or save user.nickname.should == 'ayaya' user.email.should == 'firstname.lastname@example.org' user.info.should == 'hello worl'
Just include AutoDoSomething in model class then use it like in ActiveRecord, see full example in spec/spec_helper.rb.
