Question

我有一个页面，显示图像列表和添加到该图像的点数。在本地它工作正常，但现在我想让它在我的服务器上工作，当我访问该页面时，我收到一个错误，

我们很抱歉，但出了点问题。如果您是应用程序所有者，请检查日志以获取更多信息

我的日志显示了这个，

我的show.html.haml

中的代码

- if Time.now.in_time_zone("Amsterdam") >= @competition.deadline_signin
      - @competition.pictures.shuffle.each do |picture|
        .item
          = link_to picture do
            = image_tag(picture.image_url)
          .content
            %p
              Door:
              = picture.user.name

            %p.vote
              Votes
              - if signed_in?
                - if current_user == @competition.user || current_user.administrator? || Time.now.in_time_zone("Amsterdam") <= @competition.deadline
                  = picture.points
                  -# = pluralize(picture.votes.count, "vote" )
                  -# %span
                    -# %div
                      -# %p
                        -# \ #{pluralize(picture.votes.count, "" )}
            = link_to picture.title, picture, :class => "art-name"

有谁看到问题可能是什么？

编辑“显示迁移”

20150131130944_add_points_to_pictures.rb

class AddPointsToPictures < ActiveRecord::Migration
  def change
    add_column :pictures, :points, :integer, default: 0
  end
end

迁移行动，

deploy@appsynt:~/wisemonkeys/current$ RAILS_ENV=production bundle exec rake db:migrate
==  AddPositionToPictures: migrating ==========================================
-- add_column(:pictures, :position, :integer)
   -> 0.0046s
==  AddPositionToPictures: migrated (0.0049s) =================================

==  AddPointsToPictures: migrating ============================================
-- add_column(:pictures, :points, :integer, {:default=>0})
   -> 0.0034s
==  AddPointsToPictures: migrated (0.0037s) ===================================

Answer 1

您是否在许可证（Rails 4）

上添加了Picture控制器上的点数

或

在图片模型中attr_accessible（Rails3）

访问rails页面会引发错误
