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.

# Validates that the specified attributes are not blank (as defined by Object#blank?). Happens by default on save. Example:
|
|
#
|
|
# class Person < ActiveRecord::Base
|
|
# validates_presence_of :first_name
|
|
# end
|
|
#
|
|
# The +first_name+ attribute must be in the object and it cannot be blank.
|
|
#
|
|
# If you want to validate the presence of a boolean field (where the real values are +true+ and +false+),
|
|
# you will want to use
|
|
#
|
|
# validates_inclusion_of :field_name, :in => [true, false]
|
|
#
|
|
# This is due to the way Object#blank? handles boolean values:
|
|
#
|
|
# false.blank? # => true
|
|
#
|
|
# Configuration options:
|
|
# * <tt>:message</tt> - A custom error message (default is: "can't be blank")
|
|
# * <tt>:on</tt> - Specifies when this validation is active (default is <tt>:save</tt>, other options <tt>:create</tt>, <tt>:update</tt>)
|
|
# * <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.
