Rails 6 shrine image_tag已损坏，但在新选项卡中未打开

Question

启动了一个全新的Rails 6应用程序，按照入门指南，一切都是全新的。我成功上传了文件，但在显示页面上，img标签只是一个破碎的图像图标，但如果我在新选项卡中打开它，它会显示出来。控制台中未显示错误。

/config/initializers/shorine.rb

require "shrine"
require "shrine/storage/file_system"

Shrine.storages = {
    cache: Shrine::Storage::FileSystem.new("public", prefix: "uploads/cache"), # temporary
    store: Shrine::Storage::FileSystem.new("public", prefix: "uploads")      # permanent
}

Shrine.plugin :activerecord           # loads Active Record integration
Shrine.plugin :cached_attachment_data # enables retaining cached file across form redisplays
Shrine.plugin :restore_cached_data    # extracts metadata for assigned cached files

app/uploaders/image_uploader.rb

class ImageUploader < Shrine
  # plugins and uploading logic
end

app/model/content.rb

class Content < ApplicationRecord
  include ImageUploader::Attachment(:image) # adds an `image` virtual attribute
end

视图/内容/show.html.erb

<p>
  <strong>Image:</strong>
  <%= image_tag @content.image_url %>
</p>

页面源

<img src="/uploads/efe42a8e0d19d3ffcabd26bcddd71473.mp4">

Answer 1

我想通了。我从Imgur中提取了我正在测试的"gif“，它实际上是一个mp4，因此不会在"image_tag”中显示。把它改成了"video_tag“，它起作用了。
