问题

I need a plugin for "Upload Videos" in a rails application.

Can anyone give me an idea on how to do it?

Try paperclip gem, very popular for this purpose

You can also use carrierwave gem

• Add in your Gemfile: gem 'carrierwave'

  Run bundle install

• Create an uploader for uploading video using carrierwave generator.

  rails g uploader video

• It creates file video_uploader.rb in uploaders directory

• Create a migration in model where you want attach the video or image, be careful with the migration name it should be like add_{column}_to_{model}

  rails g migration add_video_to_post video:string

• Migrate database

  Run rake db:migrate

• Add uploader to the model

  class Post < ActiveRecord::Base
        mount_uploader :video, VideoUploader  
  end
  

• Add video parameter in PostController

  class PostController < ApplicationController
        .
        . 
        .
        def post_params
            params.require(:post).permit(:name,:video)
        end
  end
  

• Add file attachment field in _forml.html.erb which is in views/posts

  <%=f.file_field :video%>
  

• To view/stream the video

  <% @posts.each do |post|%>
      <%= post.name %>
      <%= video_tag post.video_url.to_s :controls =>true %>
  <%end%>

Even more specific, I created a Rails gem that works specifically with videos: https://rubygems.org/gems/paperclip-ffmpeg
