ActiveRecord::OverflowSignalizer

One day primary key field will overflow, but if you use this gem, you will know about it before it happens.

Installation

Add this line to your application's Gemfile:

gem 'activerecord-overflow_signalizer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord-overflow_signalizer

Usage

Just place it somewhere in your app:

ActiveRecord::OverflowSignalizer.new.analyse

By default it checks all models in your application and logs if some primary key will overflow soon or overflowed. Also you can use unsafe method #analyse!, so it will raise error.

You can place it in some job and perform it by clockwork or just run it when app starts in a separate thread.

Also you can pass some parameters to the initializer:

Specify logger

ActiveRecord::OverflowSignalizer.new(logger: SomeCoolLogger)

By default ActiveRecord::Base.logger

Specify list of models

ActiveRecord::OverflowSignalizer.new(models: [ModelName])

By default it retrieves all descendants of ActiveRecord::Base

Specify count of days. Gem starts to notify you if some primary key will overflow over the next number of days.

ActiveRecord::OverflowSignalizer.new(days_count: 360)

60 days by default

You can use your own signalizer for notification sending to e-mail, slack, hipchat, etc.

class MyAwesomeSignalizer
  def initialize(some_params)
    @notifier = SomeChatNotifier.new(some_params)
  end

  def signalize(msg)
    @notifier.send_msg(msg)
  end
end

ActiveRecord::OverflowSignalizer.new(signalizer: MyAwesomeSignalizer.new(some_params))

By default it uses only logging

Development

For tests you need a postgresql connection specified in spec/database.yml.
