Embed youtube video in rails

问题

I'm trying to embed video in pages. I tried two different ways but no luck

show.html.erb

<p id="notice"><%= notice %></p>

<p>
  <b>Name:</b>
  <%= @video.name %>
</p>

<p>
  <b>Url:</b>
  <%= @video.url %>
</p>

<p>
    <% #video_tag( @video.url , :size => "560x315", :controls => true, :autobuffer => true ) %>
    <%= youtube_video @video.url%>
</p>

<%= link_to 'Edit', edit_video_path(@video) %> |
<%= link_to 'Back', videos_path %>

The video does not show neither does the links below it.

Any tips would be appreciated. Thank you

this is the debug result

回答1:

you have forgotten to close a bracket

<%= video_tag( @video.url %>

should be

<%= video_tag( @video.url ) %>

UPDATE:

Try using video_path instead of video_tag.

2nd UPDATE:

here's how I do this myself on my own site:

1 - create a partial called _video.html.erb (I actually use haml, but erb will do if you prefer it) and put it in a folder like views/shared or something ad put the following code in it:

<iframe width="490" height="275" src="<%= url %>" frameborder="0" allowfullscreen></iframe>

2 add the following method to application_helper.rb

module ApplicationHelper
  # this method will embed the code from the partial
  def youtube_video(url)
    render :partial => 'shared/video', :locals => { :url => url }
  end 
end

3 - now just call this in your views with:

<%= youtube_video @video.url %>

This works ok for me

回答2:

I got it, you forgot to use erb syntax. Try:

<iframe width="560" height="315" src= "<%= #{@video.url} %>" frameborder="0" allowfullscreen></iframe>

回答3:

@miaout17 is right, you can't use string interpolation in HTML, so you have to wrap it in Erb (e.g. <%= %>).

Also you're missing an ending ')' in your links below which is probably why they aren't working.
