Granita

Granita is a gem for simplifying the process of importing seed data from CSV files.

Granita is also a semi-frozen dessert made from sugar, water, and various flavourings, much akin to a Slurpee.

Installation

Add this line to your application's Gemfile:

gem 'granita'

And then execute:

$ bundle

Or install it yourself as:

$ gem install granita

Typical Usage

Import the Granita module into your seed file and call slurp_csv for each ActiveRecord table you want to populate.

require 'granita'

import Granita

slurp_csv 'path/to/data.csv', DataClass

This will create a DataClass instance for each row of data in the CSV file. Columns are matched using the values of the first row of the file.

Optionally, you may wish to provide a block for additional processing of rows before they are instantiated:

slurp_csv 'path/to/data_2.csv', DataClass do |row|
  # remove whitespace from the beginning and end of the title field
  row[:title].strip!

  # creates a url key from the title
  row[:url_key] = row[:title].parameterize
end
