I am trying to debug an application using Ruby on Rails(3.0.8) setup in Ubuntu using RubyMine.My application is without a database.

But when i start the server i am getting an error:-

ActiveRecord::ConnectionNotEstablished

This is the full trace of the error:-

私は/config/application.rb でrails 3.2.12 コメントを使用しており、これらを同じファイルに追加していますrequire 'rails/all'

require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"

コメントも

#config.active_record.whitelist_attributes = true

config/environments/development.rb で、これらの行にコメントを付けます

#config.active_record.mass_assignment_sanitizer = :strict
#config.active_record.auto_explain_threshold_in_seconds = 0.5

同じエラーが発生したときに、 githubでコミットを確認してください。
