Scrutanize

This library assists in auditing a database for consistency.

Specifically, it aids in the setup/organization of auditor classes and adds a simple UI for viewing audit logs.

If you're using Rails 3.2.x, you must use version ~> 0.0.1 of this gem.

in Gemfile... gem 'scrutanize'

Install the gem with rails g scrutanize:install

This will copy a migration to your project and create two files:

1. config/schedule.rb

Use this file to configure when you would like to run your audits. See
https://github.com/javan/whenever for configuration options. By default it
will run all of the audits configured in `app/models/auditors`
once a day at 4:30 am.

Once you have configured the file to your liking, write the job to your
cron file by running `whenever -w`.

If you do not want to use cron jobs to run your audits, delete this file.

2. config/initializers/scrutanize.rb

This file allow you to easily configure the back button in the audit reports view to redirect to a path of your choosing. By default it takes you to '/'.

It also has an option to override the results per page pagination.

Finally, mount the engine in your config/routes.rb mount Scrutanize::Engine => "/scrutanize"

Create auditors in app/models/auditors

Example:

# app/models/auditors/contract_auditor.rb
class ContractAuditor < Scrutanize::Auditor
  def records_to_audit
    Contract.all
  end

  def valid_record?(contract)
    contract.contract_dependency.present?
  end

  def audit_error_message
    "Contract does not have a dependency"
  end
end

Configure each auditor by specifying the records_to_audit, what makes a record valid, and the error message to log should a record fail the audit.

Whenever a record fails an audit, a entry is logged. These are viewable at 'scrutanize/audit_logs' by default but you can mount the engine where you like.

Audit logs can be deleted and undeleted.

Note: If you need to add authorization to the audit_logs views, then run rails g scrutanize:views which will copy over the controller and view files for editing.
