Allows you to create a class that has multiple error surfaces registered but stays within the familiar territory of
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install destination_errors
Here is a contrived example.
You have three models, and a form that interacts with all of them:
class User has_one :profile has_one :account end class Profile belongs_to :user end class Account belongs_to :user end
So you create an admin user form presenter class to handle everything, and you want it to be railsy.
class AdminUserFormPresenter include DestinationErrors attr_accessor :user, :profile, :account has_error_surfaces [nil, :user, :profile, :account] def initialize(*args) @surface_errors_on = nil # nil means errors will be moved onto this instance. end end

This library aims to adhere to Semantic Versioning 2.0.0. Violations of this scheme should be reported as bugs. Specifically, if a minor or patch version is released that breaks backward compatibility, a new version should be immediately released that restores compatibility. Breaking changes to the public API will only be introduced with new major versions.
As a result of this policy, you can (and should) specify a dependency on this gem using the Pessimistic Version Constraint with two digits of precision.
