I'm completely stuck on this error. Using Rails 3.1 trying to implement Formastic Bootstrap gem and getting error:

`': 没有要加载的文件 -- formtastic/helpers/buttons_helper (LoadError)

        if block_given?
          template.content_tag(:div, html_options) do
            yield

        button_html.merge!(:class => [button_html[:class], "btn commit", commit_button_i18n_key].compact.join(' '))

        # TODO We don't have a wrapper. Add deprecation message.
        # wrapper_html = options.delete(:wrapper_html) || {}
        # wrapper_html[:class] = (commit_button_wrapper_html_class << wrapper_html[:class]).flatten.compact.join(' ')

        button_html = button_html.merge(:accesskey => accesskey) if accesskey

        Formtastic::Util.html_safe(submit(text, button_html))

推荐答案

我遇到了同样的问题.显然最新版本的 formtastic 2.2.0(昨天推送)与 formtastic-bootstrap 不兼容

I had same issue. Apparently latest release of formtastic 2.2.0 (pushed yesterday) is not compatible with formtastic-bootstrap

为此，您必须指定早期版本的 formtastic

For that you have to specify earlier version of formtastic

只需在 gem 'formtastic-bootstrap'

gem 'formtastic', " ~> 2.1.1"

它是 formtastic 的早期版本.

it is little earlier version of formtastic.
