# Julia Builder [](https://travis-ci.org/stevenbarragan/julia_builder) Julia helps you out to create flexible builders to easily export your queries to csv (for now). ## Installation Add this line to your application's Gemfile: ```ruby gem 'julia_builder' ``` And then execute: $ bundle Or install it yourself as: $ gem install julia_builder For non rails projects ```ruby require 'julia' ``` ## Usage 1.- Create your own builder class, inherit from `Julia::Builder` and configure your csv columns. ```ruby class UserCsv < Julia::Builder # specify column's header and value column 'Birthday', :dob # header equals 'Birthday' and the value will be on `user.dbo` # when header and value are the same, no need to duplicate it. column :name # header equals 'name', value will be `user.name` # when you need to do some extra work on the value you can pass a proc. column 'Full name', -> { "#{ name.capitalize } #{ last_name.capitalize }" } end ``` 2.- Now you can use your builder to generate your csv out of a query like: ```ruby users = User.all UserCsv.new(users).build(<csv options>) ``` Csv opions could be anything [CSV::new](http://ruby-doc.org/stdlib-2.0.0/libdoc/csv/rdoc/CSV.html#method-c-new) understands, but they are optional. 3.- Enjoy ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/stevenbarragan/julia_builder.
