playframework-2.0

问题 Hi So I have a while loop: @for(i <- 0 until consoles.size) { ... Do something ... Add records to a column } But what I would like to add a variable and depending on what is going on add it to a different group. For example: @var column = 0; @for(i <- 0 until consoles.size) { @if(consoles[i].groupname != consoles[i - 1].groupname) { column = column + 1; } ... Do something ... Add records to a column } Is this possible. The only thing I have found is by passing in a variable and using that but

问题 In Play Framework 2.0.3 (scala), how do you determine the size (in bytes) of any Request[_]? We're trying to obtain this information for logging purposes. We would expect some value from request.body.asRaw, but we always obtain None: def logRawRequest[A](request: Request[A]) { request.body match { case c: AnyContent => println("Raw: "+c.asRaw) } } There must be something simple that we're missing, right? Thanks for the helpful answers! It turns out that the Content-Length header is only

问题 I would like to be able to have a separate directory where jar files that represent plugins can be added to a Play 2.0 project. Jar files are normally kept under the /lib directory in Play. I'd like to separate my jars in a directory called /plugins This question was asked before, but the suggestion was to just use the /lib directory. Adding additional java files to playframework classpath Is there no way to do this without manually changing the 'eclipsified' files generated by Play? 回答1: I

问题 It seems you can't mix @JsonIgnore and @JsonView. I want to hide a field by default, but show it in some cases.

问题 When client request for a file, I use this code to send it: public static Result download(String file) { File file = getRealFile(file); return Ok(file); } But I found the browser will not download it, but display its content instead. The response header: Content-Type text/plain Transfer-Encoding chunked What's the correct way to send a file? Update Per Razvi's answer, I found an answer seems good for this question: https://stackoverflow.com/a/1074925/342235 But do we really have to set so

问题 Hi I had an authentication service which works on Request (some Header-Data and Cookie), Response (to set or delete a cookie) and session (Store userId and rememberMe-information). In play 1.x it was easy to fake Request, Response, Cookie and Session. It could be easily set with Session.current().set(new Session()) . In play 2.0 this doesn't work anymore. How can I add a cookie to a request? How could I manipulate the session? I saw there exists FakeApplication and FakeRequest but I didn't

问题 I'm using Play 2.1. I'm using the default logger play.api.Logger. I'm confused about how it works.

The following will print: { "title":"Plück, Franke" } I'm trying to find if there is a header argument that I need to be passing
