RAILS_ENV =开发捆绑的exec耙分贝：种子不工作

Question

我写了这个代码

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 

和部署后，我打电话db.seed：迁移

此代码工作在我的测试环境，不在开发或集成环境。 它显示这个错误：

谁能告诉我是什么问题

Answer 1

使用此命令行

RAILS_ENV=development bundle exec rake db:seed 

如果它不工作，你可以发布文件的内容/config/initializers/authentication.rb
