This plug-in aim to resolve many problems, durling rails developping about fixtures. Basic commands is simple. Each commands load or dump fixtures.

rake db:flextures:load
rake db:flextures:dump

Major different point is four.

  1. Fixture file prefered CSV to YAML.
  2. Even if, not match column's structure, loading don't stop and auto padding data.
  3. Fixture file name can change, if file name is not equal table name.
  4. Fixture data can translate to use filter, like factory girl.

Flextures::Factory.define :users do |f|
  f.last_login_date =

This sample, generate name and sex automatically, and other tables data generate

require 'faker'
Flextures::Factory.define :users do |f| if !  # gemerate name [0,1].shuffle.first if ! # generate sex
  # factory filter can generate data, use has_many association
  f.items<< [ master_item_id: 1, count: 5 ), master_item_id: 2, count: 3 ) ]

dump filter

if you need to convert table data into other data format, you use dump filter. (dump filter is same file as load filter)

dump filter has hash arguments, it is formatted colum name key and convert method, proc, lambda value

file is config/flextures.factory.rb

Flextures::DumpFilter.define :users, {
  :encrypted_password => lambda { |v| Base64.encode64(v) }

Other options please see wiki ...

Configuration file

In config/initializers/flextures.rb, configuration file can change load and dump directory

Flextures::Configuration.configure do |config|
  # Load and dump directory change "spec/fixtures/" to "test/fixtures/"
  config.load_directory = "test/fixtures/"
  config.dump_directory = "test/fixtures/"
