RAILS_ENV=dev bundle exec rake db:seed无法工作

ruby-on-rails
3

我编写了这段代码

namespace :db do
  task :seed, :only => {:primary => true}, :except => { :no_release => true } do 
    rails_env = ENV["RAILS_ENV"]
    current_path = File.dirname(__FILE__)
    run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:seed"
  end
end

在执行deploy:migrate之后，我希望你调用db.seed。

这段代码在我的测试环境中能够正常工作，但在开发或集成环境中不能正常工作。它显示以下错误：

rake aborted!

有人能告诉我问题出在哪里吗？

应该是RAILS_ENV=development吧？ - Arjan

使用此命令行

RAILS_ENV=development bundle exec rake db:seed

如果这仍然无法解决问题，您可以发布 /config/initializers/authentication.rb 文件的内容。
