Redmine 无法在 Ruby Server 上启动 - 未定义的方法"find_by_name"

Question

我正在尝试让 Redmine 2.4.7 在 Ruby 1.9.3-p551 上运行。我按照这里的说明进行操作：http://www.redmine.org/projects/redmine/wiki/redmineinstall 使用

bundle install --without development test rmagick

我的服务器使用以下命令正确启动：

C:Redmineredmine-2.4.7>ruby script/rails server webrick -e production
 => Booting WEBrick
 => Rails 3.2.19 application starting in production on http://0.0.0.0:3000
 => Call with -d to detach
 => Ctrl-C to shutdown server
 [2015-01-06 03:44:56] INFO  WEBrick 1.3.1
 [2015-01-06 03:44:56] INFO  ruby 1.9.3 (2014-11-13) [i386-mingw32]
 [2015-01-06 03:44:56] INFO  WEBrick::HTTPServer#start: pid=11844 port=3000

但是尝试访问任何页面都会导致此错误：

NoMethodError (undefined method `find_by_name' for Setting():Class):
  app/models/setting.rb:243:in `find_or_default'
  app/models/setting.rb:108:in `[]'
  app/models/setting.rb:141:in `rest_api_enabled?'
  app/controllers/application_controller.rb:119:in `find_current_user'
  app/controllers/application_controller.rb:100:in `user_setup'

我试过了

gem update --system

但仍然是同样的问题。

安装的宝石如下：

  # (record found in database or new record with default value)
  def self.find_or_default(name)
    name = name.to_s
    raise "There's no setting named #{name}" unless @@available_settings.has_key?(name)
    setting = find_by_name(name)
    unless setting
      setting = new(:name => name)
      setting.value = @@available_settings[name]['default']
    end
    setting
  end
end

Answer 1

find_by_* 被 rails4 删除，但根据 gem 列表，我可以看到您正在使用 rails < 4 ，但我仍然相信这与 rails 版本有关。

但是，如果您查看 master 分支，则更新了语法

https://github.com/redmine/redmine/blob/master/app/models/setting.rb#L246

所以我相信升级您的redmine应该可以解决问题

Answer 2

你的输出说： app/models/setting.rb：243：in 'find_or_default'

你能给我们展示方法或至少是第 243 行周围的最小逻辑块吗？
