EasyExport

Export ActiveModels to CSV by declaring headers and fields in your model with the exportable class method and block.

Installation

Add this line to your application's Gemfile:

gem 'easy_export'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easy_export

Usage

In a model, add the exportable declaration:

class User < ActiveRecord::Base
  exportable do
    scope -> { User.all }
    fields [
      ['Header 1', -> { value to return }],
      ['Header 2', :method_name],
      ['Header 3', 'static value'], ...
    ]
  end
end

Now, use the Exporter to get the CSV data:

exporter = Exportable::Exporter.new params[:export]

exporter.data # The CSV data
exporter.file_type # 'text/csv'
exporter.file_name # 'users-<timestamp>.csv'

With those you can initiate a download from a controller:

send_data exporter.data, {
  filetype: exporter.file_type,
  filename: exporter.file_name,
  disposition: 'attachment'
}

Todo

1. Support more export types: XML, JSON, YML
2. Add method to write the data to a file
3. Clean up the way fields are declared.
