Encode an URL with Play 2

Question

How can I encode an URL in a template with Play 2?

I search a helper like this:

<a href="@urlEncode(name)">urlEncode doesn't work now</a>

I have found a pull request, but this doesn't seem to work with the actual play 2.0.3 release.

As of 2.1 you can use @helper.urlEncode

<a href="@helper.urlEncode(foo)">my href is urlencoded</a>

As I can see in linked ticked it will be resolved in Play 2.1

Quickest solution is placing ,method(s) for that in you controller (Application.java in this sample)

public static String EncodeURL(String url) throws java.io.UnsupportedEncodingException {
    url = java.net.URLEncoder.encode(url, "UTF-8");
    return url;
}

public static String EncodeURL(Call call) throws java.io.UnsupportedEncodingException {
    return EncodeURL(call.toString());
}

and then using it in the view as required at the moment:

<a href='@Application.EncodeURL(routes.Application.someAction())'>
    Encoded url form router</a>  <br/>

<a href='@Application.EncodeURL("/this/is/url/to/encode")'>
     Encoded url from string</a>  <br/>

<a href='@routes.Application.someAction()?encoded=@Application.EncodeURL(routes.Application.someOtherAction())'>
     Url mixed normal+encoded</a>  <br/>

java.net.URLEncoder is a very bad name since it should only be used to encode Query Paramters. But the general idea of how this can be implemented in play seems correct. — Jonas Geiregat, Sep 24 '13 at 08:26

Using @helper.urlEncode as in

@helper.urlEncode("http://www.giulio.ro/image/magictoolbox_cache/3bf842518f40ca6b8a10b619b8e02daf/6/2/621/thumb320x320/0804-427 - 255 lei.jpg")

returned

while what I needed/expected was
