Rake任务不将CSV添加到数据库

Question

I'm trying to add rows of a CSV to records in a table and everything seems to be working fine besides the fact that nothing actually shows up.

Here is my Rake task:

namespace :csv do

  desc "Import CSV Data"
  task :c_up => :environment do

    require 'csv'

    csv_file_path = 'db/main.csv'

    CSV.foreach(csv_file_path, :headers => true) do |row|
      row = Entry.create!({
        :one => row[0],
        :two => row[1],
        :three => row[2],
        :four => row[3],
        :five =>row[4],
        :six => row[5],
        :seven => row[6],
        :eight => row[7],
        :nine => row[8],
        :ten => row[9]
      })
      row.save
      puts "Entry added!"

    end
  end
end

The headers in my CSV are named to match the attributes.

When I run the task I receive no errors and all of the "Entry added!" show up in the console. I've tried it without the row = and row.save as I've seen lots of examples without those but it doesn't help.

After the rake finishes there aren't any records at all. Is there something obvious I'm doing wrong? It seems like this is following most examples I've seen.

Edit Thanks for all your answers and comments! Obviously this is flawed all the way down to syntax, I'm going to try out your suggestions and I'll update this after. Thanks again!

Edit 2 It turned out to be a syntax issue that you guys all pointed out, so +1 for everyone thanks! The reason when I commented it still wasn't working was an unrelated problem which I wouldn't have figured out without @jvnill's comments.

Answer 1

Entry.create! does not require being assigned to row nor does it require a row.save . Also know '{}' Just do:

Entry.create!(
        :one => row[0],
        :two => row[1],
        :three => row[2],
        :four => row[3],
        :five =>row[4],
        :six => row[5],
        :seven => row[6],
        :eight => row[7],
        :nine => row[8],
        :ten => row[9]
      )

The create method will populate the row and save it as well.

Answer 2

try with:

row = Entry.new(
        :one => row[0],
        :two => row[1],
        :three => row[2],
        :four => row[3],
        :five =>row[4],
        :six => row[5],
        :seven => row[6],
        :eight => row[7],
        :nine => row[8],
        :ten => row[9]
      )
      row.save!

Without { } , and with save!

You could even try with this, to make it simpler:

Entry.create!(row.to_hash)

Answer 3

namespace :csv do

desc "Import CSV Data" task :c_up => :environment do

require 'csv'

csv_file_path = 'db/main.csv'

CSV.foreach(csv_file_path, :headers => true) do |row|
  Entry.create!({
    :one => row[0],
    :two => row[1],
    :three => row[2],
    :four => row[3],
    :five =>row[4],
    :six => row[5],
    :seven => row[6],
    :eight => row[7],
    :nine => row[8],
    :ten => row[9]
  })
end

end end
