Error message when running Rake command in Rails app

I'm trying to create posts in my Rails app by pulling data from a CSV file.

When I try to run a Rake command, I get the error message below. What's wrong with this code?

SEED.RAKE FILE 

require 'csv'

namespace :csv do

  desc "Import CSV Data for Michelin Star Restaurants"
  task :post => :environment do

    csv_file_path = 'db/data.csv'

    CSV.foreach(csv_file_path) do |row|
        Post.create({
          :name => row[1],
          :address => row[2],
          :city => row[3],
          :michelin_status => row[4],
          :website => row[5],
          :phone => row[6],
          :longitude => row[7],
          :latitude => row[8],
          :inthenews => row[9],
          :google_reviews => row[10],
        })
      end
    end
  end

You can simply convert the original csv file to utf8 with nkf.

$ nkf -w --overwrite db/data.csv

This is because somewhere in your file there are some invalid bytes.

To avoid this issue, you can use scrub method like this:

CSV.foreach(csv_file_path) do |row|
  Post.create({
                  :name => row[1].scrub,
                  :address => row[2].scrub,
                  :city => row[3].scrub,
                  :michelin_status => row[4].scrub,
                  :website => row[5].scrub,
                  :phone => row[6].scrub,
                  :longitude => row[7].scrub,
                  :latitude => row[8].scrub,
                  :inthenews => row[9].scrub,
                  :google_reviews => row[10].scrub,
              })
end

Update

Try to specify the encoding type when you read the CSV file like this:

CSV.foreach(csv_file_path, "r:ISO-8859-1") do |row|
 . . . 
 . . . 
end
