Write CSV files as if they were normal view templates and they will be downloaded as attachments.

• Add the following to your app's Gemfile

gem 'blue-csv'

• Or as a standalone gem by running on your shell:

gem install blue-csv

The plugin exposes the object csv in your view templates, so you can write in your index.csv.blue:

csv << ["Title", "Author"]

@books.each do |book|
  csv << [book.title, book.author]
end

Your controller code would look like this:

def index
  @books = Book.all
  respond_to do |format|
    format.html
    format.csv { render :csv => 'export' }
  end
end
