# Versioned Seeds

Versioned Seeds is an alternative to Rails seeds. It allows to store your seeds in several files and prevent from re-seeding.

Rails seeds are great when you create a project but what about new ones when the project is already running ? When you have to import some data from a CSV file ?

Versioned Seeds provides a simple, conventions based, way to do that.

## Installation

    gem 'versioned_seeds', :require => false

## Usage

You can get the last imported seeds version :

    $ rake vs:status
    Last seeds: 0

Given two seeds files :

``` ruby
# db/seeds/001_create_users.rb
User.create!(:username => 'admin', :password => 'password', :admin => true)
User.create!(:username => 'user1', :password => 'password')

# db/seeds/002_import_articles.rb
require 'csv'

CSV.foreach('/some/file.csv') do |line|
  # ...
end
```

You can import only the first one by using the `vs:next` task :

    $ rake vs:next
    Loading: 001_create_users.rb

    $ rake vs:status
    Last seeds: 1

Or load all files using the `vs:all` task :

    $ rake vs:all
    Loading: 001_create_users.rb
    Loading: 002_import_articles.rb
    
    $ rake vs:status
    Last seeds: 2

Once you're at some version, any file with a version equal or inferior to that version will not be imported next time.
