Rails 4 升级的 Formtastic Gem 问题

Question

将应用程序从 Rails 3.2 升级到 Rails 4.2.8 时，ruby 版本保持不变，仍为 2.3.2。捆绑包安装和捆绑包更新运行成功，没有警告或错误。

环境： windows, ruby 2.3.2

执行任何 rake 任务或开始服务器中断，发现以下错误，

抽取任务中断：

  Error:[rake --tasks] C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/cucumber-1.1.9/lib/cucumber/ast/feature_element.rb:52: warning: circular argument reference - name

  C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/polyglot-0.3.5/lib/polyglot.rb:65:in `require'

开发服务器启动抛出错误：

  from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/activesupport-4.2.8/lib/active_support/dependencies.rb:240:in `load_dependency'

宝石文件：

   # form builder
   gem 'formtastic'

Gemfile.lock

formtastic (3.1.5)
  actionpack (>= 3.2.13)

我尝试了多个版本的 Formtastic gem，即使降到 2.0 版本也无法解决问题。让我知道是否有可用的补丁或修复程序。

更新：包括 rake 失败的错误堆栈跟踪

错误指向以下文件和 buttonhelper 调用。

    .....  
    Line no 13:
    module Helpers::ButtonsHelper
      def commit_button(*args)
        options = args.extract_options!
        text = options.delete(:label) || args.shift

        text = (localized_string(commit_button_i18n_key, text, :action, :model => commit_button_object_name) ||
            Formtastic::I18n.t(commit_button_i18n_key, :model => commit_button_object_name)) unless text.is_a?(::String)

        button_html = options.delete(:button_html) || {}
        button_html.merge!(:class => [button_html[:class], commit_button_i18n_key].compact.join(' '))

        wrapper_html = options.delete(:wrapper_html) || {}
        wrapper_html[:class] = (commit_button_wrapper_html_class << wrapper_html[:class]).flatten.compact.join(' ')

Answer 1

您似乎使用了 formtastic 和 formtastic-bootstrap gem。不幸的是 formtastic-bootstrap 与当前的 formtastic 版本不兼容，而且它似乎没有维护，因为它在过去两年中没有收到任何更新。

我看到两个选项：

降级到 formtastic ~> 2.1.1，如 this answer 中所述。
替换或分叉并修复 formtastic-bootstrap 以便能够向前移动。

我会选择第二个选项。仅仅因为它依赖于 gem（似乎无论如何都被放弃了）而使用旧的软件堆栈对我来说听起来不是一个好计划。
