acts_as_audited

acts_as_audited is an ActiveRecord extension that logs all changes to your models in an audits table.

The purpose of this fork is to store both the previous values and the changed value, making each audit record selfcontained.

Installation

    script/plugin install git://github.com/EmFi/acts_as_audited.git

Generate the migration
- If installing without a previous version of acts_as_audited or you do not mind overwriting your audits table:
```
  script/generate audited_migration add_audits_table
```
- If upgrading from a version of acts_as_audited that does not contain comment functionality:
```
  script/generate audited_migration_update update_audits_table
```
- After running one of the generators:
```
  rake db:migrate
```

Usage

Declare acts_as_audited on your models:

    class User < ActiveRecord::Base
      acts_as_audited :except => [:password, :mistress]
    end

Within a web request, will automatically record the user that made the change if your controller has a current_user method. Comments can be added to an audit by setting model.audit_comments before create/update/destroy. If the :comment_required option is given to acts_as_audited, the save/update/destroy action will fail with add an error on model.audit_comment and triggering a transaction rollback if model.audit_comment is nil.

To record a user in the audits outside of a web request, you can use as_user:

    Audit.as_user(user) do
      # Perform changes on audited models
    end

Caveats

If your model declares attr_accessible after acts_as_audited, you need to set +:protect+ to false. acts_as_audited uses attr_protected internally to prevent malicious users from unassociating your audits, and Rails does not allow both attr_protected and attr_accessible. It will default to false if attr_accessible is called before acts_as_audited, but needs to be explicitly set if it is called after.

  class User < ActiveRecord::Base
    acts_as_audited :protect => false
    attr_accessible :name
  end

Compatability

acts_as_audited works with Rails 2.1 or later.
