This change prevents a certain class of user error which results when
mistakenly using the `validate` class method instead of the `validates`
class method.
Only apply when all arguments are symbols, because some validations use
the `validate` method and pass in additional options, namely the
`LenghValidator` via the `ActiveMode::Validations::validates_with`
method.
These methods may cause confusion with the `reset_changes` that
behaves differently
of them.
Also rename undo_changes to restore_changes to match this new set of
methods.
This method name is causing confusion with the `reset_#{attribute}`
methods. While `reset_name` set the value of the name attribute for the
previous value the `reset_changes` only discard the changes and previous
changes.
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

Extract **notable changes**, **deprecations** and **removals** from
each CHANGELOG.
I tried to reference the commits and pull requests for new features
and deprecations.
In the process I also made some minor changes to the CHANGELOGS.
The 4_1_release_notes guide is declared WIP.
of an instance. When using the attribute_will_change! method, you must
supply a string and not a symbol or the *_changed? method will break
(because it is looking for the attribute name as a string in the keys
of the underlying hash). To remedy this, I simply made the underlying
hash a HashWithIndifferentAccess so it won't matter if you supply
the attribute name as a symbol or string to attribute_will_change!.
it only cleared the validations that created :validate callbacks. This
didn't include the validates created by validates_with, so I've added a
method to clear all validations.
Closes#9535.
With 692b3b6 the `password=` setter does no longer set blank passwords.
This triggered validation errors when assigning empty Strings to `password`
and `password_confirmation`.
This patch only sets the confirmation if it is not `blank?`.
