Changes you will need to make: * In your environment.rb, you will need to update references to a few files per environment.rb.tmpl * In your environment.rb, you will need to specify the local time zone of the computer that is running your Tracks install. Other notes on my changes: * Modified our code to take advantage of Rails 2.1's slick time zone support. * Upgraded will_paginate for compatibility * Hacked the Selenium on Rails plugin, which has not been updated in some time and does not support Rails 2.1 * Verified that all tests pass on my machine, including Selenium tests -- I'd like confirmation from others, too.

# Encapsulates the pattern of wanting to validate the acceptance of a terms of service check box (or similar agreement). Example:
|
|
#
|
|
# class Person < ActiveRecord::Base
|
|
# validates_acceptance_of :terms_of_service
|
|
# validates_acceptance_of :eula, :message => "must be abided"
|
|
# end
|
|
#
|
|
# If the database column does not exist, the <tt>:terms_of_service</tt> attribute is entirely virtual. This check is
|
|
# performed only if <tt>:terms_of_service</tt> is not +nil+ and by default on save.
|
|
#
|
|
# Configuration options:
|
|
# * <tt>:message</tt> - A custom error message (default is: "must be accepted")
|
|
# * <tt>:on</tt> - Specifies when this validation is active (default is <tt>:save</tt>, other options <tt>:create</tt>, <tt>:update</tt>)
|
|
# * <tt>:allow_nil</tt> - Skip validation if attribute is +nil+. (default is +true+)
|
|
# * <tt>:accept</tt> - Specifies value that is considered accepted. The default value is a string "1", which
|
|
# makes it easy to relate to an HTML checkbox. This should be set to +true+ if you are validating a database
|
|
# column, since the attribute is typecasted from "1" to +true+ before validation.
|
|
# * <tt>:if</tt> - Specifies a method, proc or string to call to determine if the validation should
|
|
# occur (e.g. <tt>:if => :allow_validation</tt>, or <tt>:if => Proc.new { |user| user.signup_step > 2 }</tt>). The
|
|
# method, proc or string should return or evaluate to a true or false value.
|
|
# * <tt>:unless</tt> - Specifies a method, proc or string to call to determine if the validation should
|
|
# not occur (e.g. <tt>:unless => :skip_validation</tt>, or <tt>:unless => Proc.new { |user| user.signup_step <= 2 }</tt>). The
|
|
# method, proc or string should return or evaluate to a true or false value.
