Please provide a full example for non ruby developper about evil-seed HOT 2 CLOSED

@jrweb247, hi!

This gem is not a standalone solution and aimed to be used with existing applications that are using ActiveRecord (Ruby on Rails or Sinatra or anything).

In case of Rails, this gem is intended to use an existing configuration of your application. So just configure your database.yml or specify DATABASE_URL environment variable.

If you want to use it as a standalone application, you can place exerything in single file like this:

#!/usr/bin/env ruby

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'activerecord'
  gem 'evil-seed'
  gem 'mysql2'
end

require 'tempfile'

class Category < ActiveRecord::Base
  has_many :translations, class_name: "Category::Translation"
end

class Category::Translation < ActiveRecord::Base
  belongs_to :category, inverse_of: :translations
end

EvilSeed.configure do |config|
  config.root("Category", "id < ?", 1000)
end

ActiveRecord::Base.establish_connection(ENV.fetch("DATABASE_URL"))

EvilSeed.dump(File.join(__dir__, "dump.sql").to_s)

And launch it like so:

DATABASE_URL=mysql2://user:pass@host/db ruby path/to/your/script.rb

Here you need to

1. Describe your database layout with ActiveRecord models (see http://guides.rubyonrails.org/active_record_basics.html)
2. Connect to your database (see http://guides.rubyonrails.org/configuring.html#configuring-a-database)
3. Start dumping
