升级导轨/可重新装载

Question

我尝试升级我的 Rails 以便将旧的 RoR 应用程序部署到 Heroku 中， 不幸的是我遇到了一些错误，而且我不知道如何解决这个问题。我的模型中的 include Reloadable 似乎不再起作用：

/usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant Artist::Reloadable (NameError)
    from /disk1/home/slugs/123146_6bfd10b_0628/mnt/app/models/artist.rb:2
    from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
    from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
    from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:158:in `require'
    from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:265:in `require_or_load'
    from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:224:in `depend_on'
    from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:136:in `require_dependency'
    from /usr/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:414:in `load_application_classes'
     ... 23 levels...

我之前的安装使用的是 RAILS_GEM_VERSION = '1.1.2'。

Answer 1

您是否尝试过删除 include Reloadable

Answer 2

Reloaded 已被弃用很长时间了。看看这个：http://weblog.rubyonrails.org/2006/8/ 11/reloading-revamped

您正在寻找的功能现在可能会自动内置到 Rails 中。
