Well, I want to replace my String param from the following Play scala Route into my own object, say "MyObject"
From GET /api/:id controllers.MyController.get(id: String)
To GET /api/:id controllers.MyController.get(id: MyOwnObject)
Any idea on how to do this would be appreciated.
Well, I have written up my own "MyOwnObject" binder now. Another way of implementing PathBindable to bind an object.
object Binders {
implicit def pathBinder(implicit intBinder: PathBindable[String]) = new PathBindable[MyOwnObject] {
override def bind(key: String, value: String): Either[String, MyOwnObject] = {
for {
id <- intBinder.bind(key, value).right
} yield UniqueId(id)
}
override def unbind(key: String, id: UniqueId): String = {
intBinder.unbind(key, id.value)
}
}
}
Use PathBindable to bind parameters from path rather than from query. Sample implementation for binding ids from path separated by comma (no error handling):
public class CommaSeparatedIds implements PathBindable<CommaSeparatedIds> {
private List<Long> id;
@Override
public IdBinder bind(String key, String txt) {
if ("id".equals(key)) {
String[] split = txt.split(",");
id = new ArrayList<>(split.length + 1);
for (String s : split) {
long parseLong = Long.parseLong(s);
id.add(Long.valueOf(parseLong));
}
return this;
}
return null;
}
...
}
Sample path:
/data/entity/1,2,3,4
Sample routes entry:
GET /data/entity/:id controllers.EntityController.process(id: CommaSeparatedIds)
I'm not sure if it works for binding data in the path part of a URL, but you may want to read the docs on QueryStringBindable
if you're able to accept your data as query params.
