Question

这个问题我一直试图在网站堆栈的帮助下解决。但不幸的是我不能这样做。所以我决定伸出援助之手。

我已尝试过所有这些链接来解决此问题。但它们都不起作用。

现在我的问题是，它始终显示一个丢失的方形图像。

以下是我的代码

Recipe.rb

 class Recipe < ApplicationRecord

        has_attached_file :image, styles: { medium:  "400x400#" },
       :path => ":rails_root/public/system/:attachment/:id/:style/:filename",
       :url => "/system/:attachment/:id/:style/:filename"

      validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/

      end

Recipe的show.html.haml

= image_tag @recipe.image.url(:medium, class: "recipe_image")

Recipe的new.html.haml

= simple_form_for @recipe, html: { multipart: true } do |f|
  - if @recipe.errors.any?
    #errors
      %p
        = @recipe.errors.count
        Prevented this recipe froms saving
      %ul
        - @recipe.errors.full_messages.each do |msg|
          %li= msg
  .panel-body
    = f.input :title, input_html: { class: 'form-control' }
    = f.input :description, input_html: { class: 'form-control' }
    = f.input :image, input_html: { class: 'form-control' }

    = f.button :submit, class: "btn btn-primary"

暂时遇到同样的问题，但我现在就修好了。

我做了什么：

浏览您的站点文件夹以查看图像的保存位置。即我的保存在与post.rb文件中显示的路径不同的路径中。我可以建议解决它。右键单击并检查损坏图像上的元素并进行比较

我相应调整，现在工作正常:)

使用回形针时图像不显示
