how to import data into rails?

Question

I have a Rails 3 application with a User class, and a tab-delimited file of users that I want to import.

How do I get access to the Active Record model outside the rails

Answer 1

You can write a rake method to so. Add this to a my_rakes.rake file in your_app/lib/tasks folder:

  desc "Import users." 
  task :import_users => :environment do
    File.open("users.txt", "r").each do |line|
      name, age, profession = line.strip.split("\t")
      u = User.new(:name => name, :age => age, :profession => profession)
      u.save
    end
  end

An then call $ rake import_users from the root folder of your app in Terminal.
