Hi,

I want to upload movies via backend.
The films are of type "file"

    public static $ has_one = array (
      "mp4" => "File"
      "m4v" => "File"
      "ogv" => "File"
      "webm" => "File"
    );
  [/ code]
Unfortunately, I get the following error!
  
    [User Error] Uncaught Exception: Object-> __call (): the method 'fortemplate' does not exist on the 'File'
  [/ code]
I can not do anything with this error message, so, anyone has an idea?

Can you provide some more info, where are you getting this error? When uplaoding files, or trying to display them in the fornt end?

Hallo zenmonkey,

i get this error in the front end, in the back end, i get no error. Uploading without errors.

Code Front end

<% loop Movies %>
    <div id="clip0" class="easyhtml5video" style="position:relative;max-width:640px;">
      <video id="video0" autoplay="autoplay" poster="$Startbild.Filename" style="width:100%" title="" loop="loop" onended="var v=this;setTimeout(function(){v.play()},300)">
        <source src="$webm" type="video/webm" />
        <source src="$mp4" />
        <source src="$ogv" type="video/ogg" />
        <source src="$m4v" type="video/mp4" />
        <object type="application/x-shockwave-flash" data="$Startbild.Filename" width="640" height="480" style="position:relative;">
          <param name="movie" value="../flashfox.swf" />
          <param name="allowFullScreen" value="true" />
          <param name="flashVars" value="autoplay=true&amp;controls=false&amp;fullScreenEnabled=false&amp;posterOnEnd=true&amp;loop=true&amp;poster=$Startbild.Filename&amp;src=$m4v" />
          <embed src="..flashfox.swf" width="640" height="480" style="position:relative;"  flashVars="autoplay=true&amp;controls=false&amp;fullScreenEnabled=false&amp;posterOnEnd=true&amp;loop=true&amp;poster=$Startbild.Filename&amp;src=$m4v"	allowFullScreen="true" wmode="transparent" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer_en" />
          <img alt="" src="$Startbild.Filename" style="position:absolute;left:0;" width="100%" title="Video playback is not supported by your browser" />
        </object>
      </video>
  </div>
<% end_loop %>
[/end]

Okay as I suspected. $webm, $ogv etc returns the file Object (the whole database record), you want to get a property off it. You'll need to use $webm.Filename. I find if the solution is video.js based you should use $webm.AbsoluteURL otherwise the falsh fallback can fail.

As an aside I would also wrap each of them in a if statement just in case the end user fails to upload one of them

<% if $webm %><source src="$webm.AbsoluteURL" type="video/webm" /><% end_if %>

It' s work!
Many, many, many THX!
