Play! framework 2.0: How to display multiple image?

Question

I need to display a gallery of photos. So here is my template:

@(photos: List[Photo])

@title = {
  Gallery
}

@main(title,\"photo\"         


        

Answer 1

Take a look at my very similar question: Direct serving files from outside of Play directories structure , finally I used my second suggestion in very basic sample it can be showed as:

public static Result serve(String filepath){
    // some stuff if required
    return ok(new File("/home/user/files/"+filepath));
}

route (use asterisk with *filepath to allow strings with slashes inside):

GET   /files/*filepath    controllers.Application.serve(filepath : String)

view (lack of @ character before photo.path is not accidental)

edit:

You of course don't need to serve files trough the controller if you have any HTTP server and ability to create new subdomain/alias pointing to directory. In such case you can just store links as http://pics.domain.tld/holidays_2012/1.jpg or even better as holidays_2012/1.jpg (and then prefix it in the template with subdomain).

Finally you can set-up some alias ie. with Apache to use your domain.tld/* as pointer to Play app and domain.tld/pics/* as pointer to some folder

  ProxyPreserveHost On
  ServerName domain.tld
  ProxyPass  /pics !
  ProxyPass / http://127.0.0.1:9000/
  ProxyPassReverse / http://127.0.0.1:9000/

  Alias /pics/ /home/someuser/somefolder_with_pics/
  
    Order allow,deny
    Allow from all
  

in such case it's important to place ProxyPass /pics ! before ProxyPass / http://...
