ArTruncator

Now you can do tablename.truncate. This was not incorporated into AR as a patch because SQLite does not support truncate statements. See this pull request for more detail:

https://github.com/rails/rails/issues/5510

I'm releasing this as a gem, so I don't have to add it to my config/initializers.

This has so far only been tested for mysql2 adapater/MySQL DB.

Why truncate versus delete * ? Its more performant and it resets the primary key ID to 1. Useful when you're re-seeding/testing.

Installation

Add this line to your application's Gemfile:

gem 'ar_truncator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ar_truncator

Usage

If you have a model called Dummy, to truncate it do:

Dummy.truncate

This will execute the following sql:

"Truncate tabel Dummies".
