File download with ninja

[John Purnell]

How do I do a file download in ninja.

Here is a similar question for play http://stackoverflow.com/questions/13269382/play-framework-2-0-4-file-download

I have a File object and would like to stream it back like the answer above.

The file is text ( a GEDCOM file ) but large, so I could read it into a string and do a renderRaw but is there a better way?

Hey John,

there is something similar in our integration tests here:
https://github.com/ninjaframework/ninja/blob/develop/ninja-servlet-integration-test/src/main/java/controllers/UploadController.java

It's of course not exactly what you are asking for. A stripped down
version would be that here:

Renderable renderable = new Renderable() {

@Override
public void render(Context context, Result result) {
ResponseStreams responseStreams = context.finalizeHeaders(result);
responseStreams.getOutputStream() // do what you want with the streams
}
};
return new Results.ok().render(renderable);

you can set the headers and everything else before calling "
context.finalizeHeaders(result);"

Cheers,

Raphael
