I decided to try scala out with play2. I am trying to somehow get a config section out of application config. It looks like this (by section I mean whole mail part)
services: {
rest: {
mail: {
uri: "xyz",
authorization: {
username: "xyz",
password: "xyz"
}
}
}
}
Code
import com.typesafe.config.ConfigObject
import play.api.Play.current
val config: Option[ConfigObject] = current.configuration.getObject("services.rest.mail")
This gives Some(SimpleConfigObject()) and trough there the only way I am able to actually get mail section and use it as a ConfigObject is trough
config.get.toConfig.getString("uri")
Or I can get the actual value with
config.get.get("uri").unwrapped().toString
Or for fun:
config.get.toConfig.getObject("authorization").toConfig.getString("username")
Either way it seems to me I am doing it overly complicated. Is there some easier way to get a section from config?
Since the config library has a Java API, it can feel a bit verbose using it from Scala. There are some Scala wrappers though that enable more compact syntax. See https://github.com/typesafehub/config#scala-wrappers-for-the-java-library.
I will post this as an answer for future reference.
After another while of playing with the code I have found parseResourcesAnySyntax method which does exactly what I want and since I have my config split into multiple parts for separate environments (application.dev.conf, etc.) I can simply do
import com.typesafe.config.{Config, ConfigFactory}
import play.api.Play._
val config: Config = ConfigFactory.parseResourcesAnySyntax("application.%s.conf" format current.mode)
and then use
config.getString("uri")
// or
config.getString("authorization.username")
// or if I want to use part of it as another section
val section: Config = config.getConfig("authorization")
section.getString("username")
Of course, another viable alternative is using a wrapper as mister Stebel recommended.

Noob to Gatling/Scala here.
This might be a bit of a silly question but I haven't been able to find an example of what I am trying to do.
I want to pass in things such as the baseURL, username and passwords for some of my calls. This would change from env to env, so I want to be able to change these values between the envs but still have the same tests in each.
I know we can feed in values but it appears that more for iterating over datasets and not so much for passing in the config values like I have.
Ideally I would like to house this information in a JSON file and not pass it in on the command line, but maybe thats not doable?
Any guidance on this would be awesome.
I have a similar setup and you can use pure scala here .In this scenario you can create an object called Config for eg
object Configuration { var INPUT_PROFILE_FILE_NAME = ""; }
This class can also read a file , I have the below code in the above object
val file = getClass.getResource("data/config.properties").getFile()
val prop = new Properties()
prop.load(new FileInputStream(file));
INPUT_PROFILE_FILE_NAME = prop.getProperty("inputProfileFileName")
Now you can import this object in Gattling Simulation File
val profileName= Configuration.INPUT_PROFILE_FILE_NAME ;

I tried to use CasperJS for headless browser testing using PhantomJS and wanted to have a config file or something to change Website URL, Username passwords etc. So finally I found NuclearJS. Do you guys know any other perfect way to do this? If I wanted to write a one from the scratch would like to know about as well.
I got a solution (not perfect ;) ) that is using multiple configfiles (for selector, execution, desktop, mobile, etc).
I include a in the execution of my casperjs tests a file that offers me all configs i need (i include also global functions there).
Lets guess the test execution looks like that:
casperjs test --includes=loadGlobals.js test_1.js
In the that example loadGlobals.js contains functions like that:
var fs = require('fs');
var config = {},
configFile = fs.read('config.json');
config = JSON.parse(configFile);
Probalby the config.json is looking like that:
{
"url": "http://www.yourTestUrl.com",
"variable_1": "bla",
"variable_2": "blub",
"nextTier": {
"variable_1": "blablub"
}
}
Now you can call in the test_1.js the variables of the config.json:
casper.start(config.url, function() {
casper.then(function() {
casper.echo(config.variable_1);
casper.echo(config.variable_2);
casper.echo(config.nextTier.variable_1);
});
})
casper.run();
You can use like that different configurationfiles, even to override it during tests if nessacary.
The tests should be written in the page object pattern style so they are highly maintable, espacially with a outsourced configuration.
NuclearJS i didn't know, but i will take a look into it, too.
I am a Scala/PlayFramework noob here, so please be easy on me :).
I am trying to create an action (serving a GET request) so that when I enter the url in the browser, the browser should download the file. So far I have this:
def sepaCreditXml() = Action {
val data: SepaCreditTransfer = invoiceService.sepaCredit()
val content: HtmlFormat.Appendable = views.html.sepacredittransfer(data)
Ok(content)
}
What it does is basically show the XML in the browser (whereas I actually want it to download the file). Also, I have two problems with it:
I am not sure if using Play's templating "views.html..." is the best idea to create an XML template. Is it good/simple enough or should I use a different solution for this?
I have found Ok.sendFile in the Play's documentation. But it needs a java.io.File. I don't know how to create a File from HtmlFormat.Appendable. I would prefer to create a file in-memory, i.e. no new File("/tmp/temporary.xml").
EDIT: Here SepaCreditTransfer is a case class holding some data. Nothing special.
I think it's quite normal for browsers to visualize XML instead of downloading it. Have you tried to use the application/force-download content type header, like this?
def sepaCreditXml() = Action {
val data: SepaCreditTransfer = invoiceService.sepaCredit()
val content: HtmlFormat.Appendable = views.html.sepacredittransfer(data)
Ok(content).withHeaders("Content-Type" -> "application/force-download")
}
I know that the earlier versions of Play used to support routes and conditionals (if blocks) in the routes file but I cannot find any such documentation for Play 2.2.x and HTTP routing says nothing about such a feature.
I want to replace this:
GET /api/users/:id com.corporate.project.controllers.UserController.get(id)
with a shorter version using import as follows:
import com.corporate.project.controllers._
GET /api/users/:id UserController.get(id)
Also, is it possible to have conditionals in the routes file? e.g.
if Play.isDev(Play.current())
GET /displayConfig DebugController.displayServerConfigs()
Package imports used to be possible with an SBT setting: routesImport += "com.corporate.project.controllers._". Not sure if it is still the case.
Also, is it possible to have conditionals in the routes file?
It might not be an ideal solution but we use routes tags to deal with this kind of conditional routes. You need a filter that checks if the route is annotated and runs your conditional logic.
Routes:
# #devmode
GET /displayConfig DebugController.displayServerConfigs()
Filter:
object DevmodeRouteFilter extends Filter {
private val DevmodeAnnotation = "#devmode"
override def apply(next: RequestHeader => Future[SimpleResult])(request: RequestHeader): Future[SimpleResult] = {
if(isDevRoute(request) && !Play.isDev(Play.current()) {
Play.current.global.onHandlerNotFound(request)
} else {
next(request)
}
}
private def isDevRoute(request: RequestHeader): Boolean = {
val comments = request.tags.getOrElse(Routes.ROUTE_COMMENTS, "")
comments.lines.exists { comment =>
comment.trim == DevmodeAnnotation
}
}
}
Don't forget to add the filter to the filter chain.
Thank you for your question, it is an interesting idea, so I went to the sources of Play2 and found that in my checkout of Play 2.2.3 in the play.core.Router.scala: object HandlerInvoker constructs controller as
handlerDef.ref.getClass.getClassLoader.loadClass(handlerDef.controller)
So I am afraid that support for partial class names (stored in handlerDef.controller) is not implemented in 2.2.x.
In 2.3.x there is commit https://github.com/playframework/playframework/commit/ba98dabd7ba374ed98f14f721835b898d27dd55b
that brought notion of package/namespace for the routes.
Please see changes in Routes.scala and RoutesCompiler.scala from that commit.
But I can't find description of that functionality in the documentation and I do not have Play 2.3.x to play with it now.
P.S.: Sample magic for advanced routing for 2.3.x described in http://java.dzone.com/articles/advanced-routing-play .
I am building an application using the Play! framework version 2.0.4. Some pages that are legally required such as an imprint mostly contain lots (some 10k each) of static text which I would like to provide in different languages.
In versions 1.x there was an #include directive that allowed to construct the actual resource path using the current Lang.
What is the recommended way of implementing sth similar with Play 2.x?
Thank you & best regards,
Erich
I'm not 100% certain how you implement it as of now, but here's what I've come up with.
You could just write your own include helper. Save the following in a file Helpers.scala in your views folder. Explanations are in the code's comments.
package views.html.helper
object include {
import play.api.templates.Html
import play.api.Play
import play.api.Play.current
import play.api.i18n._
// The default is to look in the public dir, but you can change it if necessary
def apply(filePath: String, rootDir: String = "public")(implicit lang: Lang): Html = {
// Split filePath at name and suffix to insert the language in between them
val (fileName, suffix) = filePath.splitAt(filePath.lastIndexOf("."))
// Retrieve the file with the current language, or as a fallback, without any suffix
val maybeFile =
Play.getExistingFile(rootDir + "/" + fileName + "_" + lang.language + suffix).
orElse(Play.getExistingFile(rootDir + "/" + filePath))
// Read the file's content and wrap it in HTML or return an error message
maybeFile map { file =>
val content = scala.io.Source.fromFile(file).mkString
Html(content)
} getOrElse Html("File Not Found")
}
}
Now in your imprint.scala.html you could call it like this:
#()(implicit lang: Lang)
#import helper._
#include("static/imprint.html")
Way showed by Schleichardt was used in play-authenticate to select mail templates in different languages and now it's changed to work with reflections on the controller, so maybe it can be interesting for you. Anyway it was intendent to keep standard templating possibilities (cause each mail need to be personalized before send)
For static info pages, you can just save the code for each language with suffix ie. impressum_en.html, impressum_de.html in the file system and use simple controller which will find file with proper suffix and return its content exactly as it is... all you need probably to return Ok(fileContent) and set the Content-Type manually to text/html.
Other option is doing the similar thing but storing it in the DB, so you can create simple back-end and edit it with browser.
If you still need to replace some elements, you can do it with some ###MARKER### in the code + simple String operations, or with JavaScript on the client side.
Templates in 2.0 work a bit differently. The Scala based templates are compiled. From one template instead of 'including' another, you can make a call to it. I'm not sure exactly what you mean by the language thing. In 2.0 though, a parameter to the template could be the language.
Example template named 'included' in package whateverpackage.
#(lang: Lang)
...
Example calling a template named 'included':
#import whateverpackage._
#included(Lang("en"))
#()(implicit lang: Lang)
#main(Messages("imprint")) {
#lang match {
case Lang("de", _) => { #germanImprint() #* uses app/views/germanImprint.scala.html file *#}
case _ => { #englishImprint() }
}
}
