我真的需要将数据部署到我的heroku应用程序，但我不明白它为什么不能正常工作。我已经阅读了文档，并且我已经在seeds.rb文件中播种了我的数据库，如下所示：
user = User.create(band_name: "The Rubies", email: "therubies@gmail.com", user_name: "therubies1000", password: "password", password_confirmation: "password")
MusicVideo.create([
{song_title: "Ruby Gems"

])
然后我运行了heroku rake db：migrate，然后运行了heroku rake db：seed，如rails app项目网站所示。我尝试对此进行问题排查，但我不知道从哪里开始或如何开始。这些命令应该有效。我真的可以帮上忙。
---- ----- EDIT
当我使用两个rake命令时，我根本没有收到任何错误。我明白了：
➜ musikfish git:(master) ✗ heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.8472
➜ musikfish git:(master) ✗ heroku run rake db:seed
Running `rake db:seed` attached to terminal... up, run.9065
问题是当我去我的heroku应用程序时，没有任何东西。

您是否已成功在本地播种数据库？
您还可以尝试在种子文件中添加puts行，以确保正在运行代码。 （IE，在MusicVideo.create之后，说puts "Music Videos created!"，在运行rake db:seed时将写入您的控制台
我的预感是你的模型验证失败;也许尝试使用create!而不是create来查看是否抛出了错误。
