从Heroku迁移到Dokku(数字海洋)

Question

我正在将所有内容从Heroku关闭，然后转移到数字海洋（便宜且静态IP地址！！）

我在Heroku上有搜索框。而且我需要在数字海洋上这样的东西。

目前，我正在遇到一个错误的错误（仍然为Heroku设置？），看起来像这样

  def search
    @events = Event.where("event_type != 'festival' AND complete = true").page(params[:page]).per(10).search params[:search], suggest: true, misspellings: { distance: 1 }, order: { date: :asc, eventname: :asc }, match: :word_start
    if @events.results.any?
      render 'events/results'
    else
      render 'events/noresults'
    end
  end

您可以使用官方的dokku-elasticsearch插件来设置ES实例并将其链接到您的应用程序。完成后，ELASTICSEARCH_URL将设置为您的应用程序，只要您的代码尊重，您就应该很好。
