Question

我有一个Rails应用程序，在我的开发机器上工作得很好，但是当我将它部署到Heroku时，我在部署后尝试加载页面时收到以下错误消息。

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

31: <div id="tickets">
32:      <div id="subline">Tickets open for trading</div>
33:           <% if not @tickets.blank? %>
34:                <%= render( :partial => '/choices/choice.html.erb', :locals => { :choice => @tickets} ) %>
35:           <% end %>
36:      </div>

app/views/home/index.html.erb:34:in `_app_views_home_index_html_erb___4151329774010405498_38984040'
app/controllers/home_controller.rb:108:in `index'

我似乎无法弄清楚出了什么问题，因为它在我自己的机器上工作正常，所以任何帮助都会非常适合：）

编辑1：

这是我的家庭控制器的一部分，与上述相关..

class HomeController < ApplicationController

  def index
    @tickets  = Choice.betable(current_user).where("choices.created_at > ?", Time.at(params[:after].to_i + 1).utc).order("choices.created_at DESC")

    respond_to do |format|
      format.html      
      format.json do
        @html_choice            = render_to_string( :partial => '/choices/choice.html.erb', :locals => { :choice => @tickets} )
        @html_active_choices    = render_to_string( :partial => '/shared/active_choices.html.erb', :locals => { :active_choices => @active_choices} )
        @html_active_bets       = render_to_string( :partial => '/shared/active_bets.html.erb', :locals => { :active_bets => @active_bets} )
        @html_spotprices_today  = render_to_string( :partial => '/shared/spotprices_today.html.erb', :locals => { :spotprices_today => @spotprices_today} )

        render :json => { :success => true, :html_choice => @html_choice, :html_active_choices => @html_active_choices, :html_active_bets => @html_active_bets, :html_spotprices_today => @html_spotprices_today  }
      end
    end
  end
end

希望这有助于找到导致错误的原因：）

谢谢！

Answer 1

尝试更改：
... :partial => '/choices/choice.html.erb'

于：
... :partial => '/choices/choice'

在您的视图和控制器中。为了帮助您更清楚，请查看Using Partial。

Answer 2

我的网络应用程序中出现了同样明显误导性的错误，仅在生产环境中引发但是在开发过程中一切正常。

我的日志如下：

NoMethodError (undefined method `call' for :silence:Symbol):
  app/controllers/users_controller.rb:77:in `block in XXX'
  app/controllers/users_controller.rb:77:in `each'
  app/controllers/users_controller.rb:77:in `XXX'
  app/controllers/users_controller.rb:32:in `YYY'
  app/controllers/application_controller.rb:46:in `ZZZ'

请注意，调试器指出的上下文完全不同。由于此错误仅在生产环境中出现，我认为它可能不是由某些编码错误引起的。所以我开始研究开发和生产设置之间的差异，并最终发现我添加了以下行以摆脱一些嘈杂的Heroku弃用警告：

config.active_support.deprecation = :silence

但由于“：沉默”符号尚未在DEFAULT_BEHAVIORS [：沉默]中定义，（检查https://github.com/rails/rails/pull/5986），因此导致了问题。既然你也说你正在使用Heroku，那么请你检查一下这是否也是你错误的原因？

Answer 3

必须：

设置 formats 和 handlers

示例：

@html_choice = render_to_string( \ partial: '/choices/choice', \ formats: [:html], handlers: [:erb], \ locals: {choice: @tickets})

未定义的方法`call'for：silence：符号错误
