回形针视频上传 [英] Paperclip Video Upload

问题描述

我试图在我的帖子中启用视频上传。
无法显示视频。视频上传，我可以确认，虽然我设法右键点击视频区域，并下载它。问题是如何正确查看它。

迁移：

  class AddAttachmentVideoToPosts< ActiveRecord :: Migration 
 def self.up 
 change_table：posts do | t | 
 t.attachment：video 
 end 
 end 
 
 def self.down 
 drop_attached_file：posts，：video 
 end 
 end 
 def def 
 create_table：videos do | t | 
 t.string：video_file_name 
 t.string：video_content_type 
 t.integer：video_file_size 
 t.datetime：video_updated_at 
 
 t.timestamps 
结束
结束
  

发布模型

  class Post< ActiveRecord :: Base 
 default_scope：order => 'created_at desc'
 attr_accessible：content，：title，：photo，：photo_delete，：video，：video_delete，：dependent => ：销毁
 has_attached_file：photo，：styles => {：thumb => 600x600＃，：medium => 300x300＃，：small => 160x160＃} 
 has_attached_file：video 
 validates_uniqueness_of：title 
 validates_presence_of：title，：content 
 has_destroyable_file：photo，：video 
 end 
  

我的帖子中的视频部分_form



 < div class =visible-md visible-lg> 
 <％= f.file_field：video，：style => 浮动：离开 ％GT; 
<％= f.check_box：video_delete，：style => 浮动：离开 ％GT; & nbsp;删除影片
< / div>< br /> 
< div class =visible-xs> 
 <％= f.file_field：video，：style => 中心％> 
<％= f.check_box：video_delete，：style => 中心％> & nbsp;删除影片
< / div>< br /> 
  

发布视频中的视频部分



 <％if @ post.video？ ％GT; 
< h1 class =center> 
<％= @ post.title％> 
< / h1>< br /> 
<％= video_path @ post.video.url％> 
<％end％> 
  

我也尝试过使用video_tag，这些都不起作用，当我尝试使用：

 < iframe width =490height =275src =<％= video_path @ post.video.url％>  frameborder =0allowfullscreen autoplay =true> 
< / iframe> 
  

我得到一个不会玩的玩家。
如果你仔细观察，可能会很感激，也许可以帮助我想出一个可行的解决方案。您应该使用视频标记，而不是<$ c $ c> iframe （只有 video 标签有自动播放选项）。在此查看浏览器支持哪些格式： http://caniuse.com/#search=video

I'm trying to enable video upload in my post. Can't get it to display the video. The video gets uploaded, I can confirm that while i manage to right click on the video area and download it. The problem is how to view it correctly.

Migration:

class AddAttachmentVideoToPosts < ActiveRecord::Migration
  def self.up
    change_table :posts do |t|
      t.attachment :video
    end
  end

  def self.down
    drop_attached_file :posts, :video
  end
end
 def change
    create_table :videos do |t|
        t.string :video_file_name
        t.string :video_content_type
        t.integer :video_file_size
        t.datetime :video_updated_at

        t.timestamps
    end
end

Post Model

class Post < ActiveRecord::Base
    default_scope :order => 'created_at desc'
    attr_accessible :content, :title, :photo, :photo_delete, :video, :video_delete, :dependent => :destroy
    has_attached_file :photo, :styles => {  :thumb => "600x600#", :medium => "300x300#", :small => "160x160#"}
    has_attached_file :video
    validates_uniqueness_of :title
    validates_presence_of :title, :content
    has_destroyable_file :photo, :video
end

Video part in my post _form

<div class="visible-md visible-lg">
  <%= f.file_field :video, :style => "float: left;" %>
  <%= f.check_box :video_delete, :style => "float: left;" %> &nbsp;Delete video
  </div><br />
<div class="visible-xs">
  <%= f.file_field :video, :style => "center" %>
  <%= f.check_box :video_delete, :style => "center" %> &nbsp;Delete video
</div><br />

Video part in Post Show

<% if @post.video? %>
<h1 class="center">
<%= @post.title %>
</h1><br />
<%= video_path @post.video.url %>       
<% end %>

I have also tried with video_tag which don't work and when I try with:

<iframe width="490" height="275" src="<%= video_path @post.video.url %>" frameborder="0" allowfullscreen autoplay="true">
            </iframe>

I get a player that won't play. Would really appreciate if you look it through and maybe help me to come up with a solution that will work. Thanks!

解决方案

You should use video tag, not iframe (only video tag has autoplay options). Check here what formats are supported by what browser: http://caniuse.com/#search=video

If you want crossbrowser solution, try VideoJS - http://www.videojs.com/ Here you can get a Rails plugin - https://github.com/seanbehan/videojs_rails
