Yves Senn 7d196cf360 #to_param returns nil if to_key returns nil. Closes #11399. 
The documentation of `#to_key` (http://api.rubyonrails.org/classes/ActiveModel/Conversion.html#method-i-to_key)
states that it returns `nil` if there are no key attributes. `to_param` needs
to be aware of that fact and return `nil` as well.

Previously it raised the following exception:

```
  1) Error:
ConversionTest#test_to_param_returns_nil_if_to_key_is_nil:
NoMethodError: undefined method `join' for nil:NilClass
    /Users/senny/Projects/rails/activemodel/lib/active_model/conversion.rb:65:in `to_param'
    /Users/senny/Projects/rails/activemodel/test/cases/conversion_test.rb:34:in `block in <class:ConversionTest>'
```

  • Ability to specify multiple contexts when defining a validation.

    Example:

    class Person
  include ActiveModel::Validations

  attr_reader :name
  validates_presence_of :name, on: [:verify, :approve]
end

person = Person.new
person.valid?                           # => true
person.valid?(:verify)                  # => false
person.errors.full_messages_for(:name)  # => ["Name can't be blank"]
person.valid?(:approve)                 # => false
person.errors.full_messages_for(:name)  # => ["Name can't be blank"]

  • attribute_changed? now accepts a hash to check if the attribute was changed :from and/or :to a given value.

    Example:

    model.name_changed?(from: "Pete", to: "Ringo")

  • Fix has_secure_password to honor bcrypt-ruby's cost attribute.

    T.J. Schuck

  • Updated the ActiveModel::Dirty#changed_attributes method to be indifferent between using symbols and strings as keys.

    William Myers

  • Added new API methods reset_changes and changes_applied to ActiveModel::Dirty that control changes state. Previsously you needed to update internal instance variables, but now API methods are available.

    Bogdan Gusiev

  • Fix has_secure_password not to trigger password_confirmation validations if no password_confirmation is set.

    Vladimir Kiselev

  • inclusion / exclusion validations with ranges will only use the faster Range#cover for numerical ranges, and the more accurate Range#include? for non-numerical ones.

    Fixes range validations like :a..:f that used to pass with values like :be. Fixes #10593.

    Charles Bergeron

  • Fix regression in has_secure_password. When a password is set, but a confirmation is an empty string, it would incorrectly save.

    Steve Klabnik and Phillip Calvin

  • Deprecate Validator#setup. This should be done manually now in the validator's constructor.
