# Versioned Seeds [](http://travis-ci.org/simonc/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
Add this line to your `Gemfile` :
gem 'versioned_seeds', :require => false
If you're using Git, as you should, be sure to call this in your shell :
$ echo ".versionned_seeds" >> .gitignore
## Usage
### Get current version
You can get the last imported seeds version :
$ rake vs:status
Last seeds: 0
### Generate a seeding script
The generator will simply generate a timestamped file where you can put anything you want :
$ rails g versioned_seeds:seed_file some_seeding_script
create db/seeds/20111205155806_some_seeding_script.rb
### Loading the scripts
Given two seeds files :
``` ruby
# db/seeds/20111205155801_create_users.rb
User.create!(:username => 'admin', :password => 'password', :admin => true)
User.create!(:username => 'user1', :password => 'password')
# db/seeds/20111205155802_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: 20111205155801_create_users.rb
$ rake vs:status
Last seeds: 20111205155801
Or load all files using the `vs:all` task :
$ rake vs:all
Loading: 20111205155801_create_users.rb
Loading: 20111205155802_import_articles.rb
$ rake vs:status
Last seeds: 20111205155802
Every script imported once will never be loaded again.
