ActionView::Template::Error(未定义的方法`silence')

ActionView::Template::Error (undefined method `silence' for)

我在 heroku 上有一个很奇怪的问题。我的视图如下所示:

= content_for :header_title do
  = t('.header_title')

- if @appointments.exists?
  %table.table.table-striped.table-bordered.table-hover
    %thead
      %tr
        %th= t('.id')
        %th= t('.athena_health_id')
        %th= t('.start_time')
        %th= t('.duration')
        %th= t('.provider')
        %th= t('.created_at')
        %th= t('.updated_at')
    %tbody
      = render @appointments

  = paginate @appointments
- else
  %h3.text-center= t('.appointments_not_found')
%hr/

没什么特别的。当我访问在 heroku 上使用此模板的页面时,我收到:

 ActionView::Template::Error (undefined method `silence' for #<Logger:0x007f7a86267a70>):

规格正在通过。在我的本地一切正常。我不知道发生了什么。 Stacktrace 显示问题出在以下行:

= paginate @appointments

我正在使用 Rails 5.0 和 kaminari (1.0.0.alpha)。有什么想法吗?

编辑: 在我的 production.rb 中,我有:

  if ENV['RAILS_LOG_TO_STDOUT'].present?
    config.logger = ActiveSupport::TaggedLogging.new(Logger.new(STDOUT))
  end

config.log_formatter = ::Logger::Formatter.new

在 Rails5 中,silence 方法已从 ::Logger 基础 class 中删除(参见此 issue

因此,要传递 ::Logger 实例,请尝试传递公开 silence 方法的 ActiveSupport::Logger 实例(参见 documentation),如下所示:

config.logger = ActiveSupport::TaggedLogging.new(ActiveSupport::Logger.new(STDOUT))

注意: ActiveSupport::Logger 继承自 ::Logger 基础 class 并包含 LoggerSilence 模块(参见 documentation

来自我的 rails 控制台的示例(rails5 和 ruby​​2.3.​​0)
