Rails - Feb 2008 - I want to specify the exact root to play video files in my r

Hi all,

can anyone please get me a solution for the problem i am facing in my
project..

i am using this path

VALUE="#{RAILS_ROOT}/<%=@f.content_path%>"

to display and play a video in my project

where @f.content_path this variable prints a root like this

#{RAILS_ROOT}/E:/project_name/public/folder_name/id/file.mpg

but its not at all working..

if the path is like this /public/folder_name/id/file.mpg

when i embed like this.. its working.. what could be the problem?

<div>
<%if @f_len!=0%>
<%for @f in @focus%>
<%if @f.content_type==''Videos''%>
<%puts @f.content_path%>
<%puts @f.id%>
<OBJECT ID="MediaPlayer" WIDTH="370"
HEIGHT="270"
CLASSID="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95"
STANDBY="Loading Windows Media Player components..."
TYPE="application/x-oleobject">
<PARAM NAME="FileName"
VALUE="#{RAILS_ROOT}/<%=@f.content_path%>">
<PARAM name="autostart" VALUE="false">
<PARAM name="ShowControls" VALUE="true">
<param name="ShowStatusBar" value="true">
<PARAM name="ShowDisplay" VALUE="false">
<EMBED TYPE="application/x-mplayer2"
SRC="#{RAILS_ROOT}/<%=@f.content_path%>"
NAME="MediaPlayer"
WIDTH="370" HEIGHT="270" ShowControls="1"
ShowStatusBar="1"
ShowDisplay="0" autostart="0"> </EMBED>
</OBJECT>
<%else%>
  <%=link_to_remote(image_tag(url_for_file_column("f",
"image_path",:big)))%>
<%end%>
<%end%>
<%else%>
NO PREVIEW
<%end%>
</div>

it''s basically a bad idea, to create paths like this:
"#{RAILS_ROOT}/<%=@f.content_path%>"

use the File.join method instead
File.join(RAILS_ROOT, @f.content_path)
this will save you a lot of trouble with missing slashes etc.

#{RAILS_ROOT}/E:/project_name/public/folder_name/id/file.mpg
cant work
assume a windows machine and your project is:
C:\projects\myproject
which is rails_root then

C:\projects\myproject/E:/project_name/public/folder_name/id/file.mpg

that''s not a valid path, eg because of the two discs C: E: and the mix 
of slashes/backslashes

what kind of OS are you using, since the drive letters would be Windows 
like, but you use the slashes like for unix or mac?

i am using windows xp

basically #{RAILS_ROOT} will take the path where the project will be.so 
in my task if i give
#{RAILS_ROOT}\@f.content_path means it should show the path like 
\public\folder_name\id\file.mpg right? but instead it shows the path as 
E:\project_name\public\folder_name\id\file.mpg. how to solve this 
problem..

thanks,
barak

Um no. RAILS_ROOT is the location on disk of your rails app, ie E: 
\project_name in your case.
I''ve no idea what f and its content_path method are, but what you want
to give to the user''s browser is a path relative to the public/ folder
in your rails app

forget about RAILS_ROOT on the browser-site. only use relative url

if i want to display an image in /public/files, i would use this:
"/files/#{image.image_filename}"
if the images are in /public/files

everything else will be resolved by the browser and server

so your line
SRC="#{RAILS_ROOT}/<%=@f.content_path%>"

should work like this:
SRC="<%=@f.content_path%>"
if content_path points to the right place and does not have the leading 
/public
