Question

我使用Paperclip已近一个月了，效果很好。在配置和测试准备工作中进行了一些修复之后它就会掉下来，现在它正在正确地保存图像，但是显示了类似于＆＃39;％D0％97％D0％BD％D1％8F％D1％82％D0％BE％D0 ％BA_％D0％B5％D0％BA％D1％80％D0％B0％D0％BD％D1％83_％D0％B7_2016-06-28_11-35-01＆＃39;而不是图片本身。所有图片都是从文件字段标签上传的。你能告诉我如何解决这个问题或建议指南修补这类东西吗？
我的模特：

class Initiative < ActiveRecord::Base
  paginates_per 3
  include InitiativeStates

  scope :searched, ->(query) { where('title LIKE ?', "%#{query}%") }

  resourcify

  belongs_to :user
  has_many :timelines
  has_many :initiative_categories
  has_many :categories, through: :initiative_categories, class_name: 'Category'
  accepts_nested_attributes_for :initiative_categories
  accepts_nested_attributes_for :categories

  has_attached_file :main_image,
                    path: ':rails_root/public/system/:attachment/:id/:style/:filename',
                    url: '/system/:attachment/:id/:style/:filename',
                    default_url: ':rails_root/public/default/def.phg'

  validates :title,
            presence: true
  validates :short_description,
            length: { maximum: 200 },
            presence: true
  validates :needed_sum,
            inclusion: 100..50_000

  validates_attachment :main_image,
                       content_type: { content_type: %w[image/jpeg image/gif image/png] },
                       presence: true
end

主要观点：

<div class="initiatives">
  <div class="row">
    <%@initiatives.each do |initiative| %>
        <div class="col-md-4 col-sm-6 col-xs-12">
          <%=render 'shared/short_view_initiative', initiative:initiative %>
        </div>
        <%= %>
    <%end%>
  </div>

倡议的分享：

  <div class="initiative">
      <%=link_to initiative_path(initiative) do%>
          <div class="frame">
            <%= image_tag initiative.main_image(:medium), class: 'initiative-image' %>
          </div>
      <%end%>
      <div class="initiative-title">
        <strong><%=initiative.title%></strong>
      </div>
      <div class="initiative-short-description">
        <p><%=initiative.short_description %></p>
      </div>
      <% if user_signed_in? && (current_page? user_show_initiatives_path(current_user))%>
          <div class="initiative-state">
            <b><%=find_out_initiative_state(initiative)%></b>
          </div>
      <%end%>
    </div>

控制器的一部分： class InitiativesController＆lt; ApplicationController中

  def index
    @initiatives = Initiative.approved.order('approved_at ASC').page(params[:page])
  end
end

我为它创建了一个适当的迁移，所有准备工作都已完成，一切正常。此外，img标签链接指向这些文件所在的正确目的地，但它不会渲染图像。

Paperclip保存图像，但不会在视图中显示
