digiplant / play-res   1.2.0


Resource plugin for Play Framework 2

Scala versions: 2.11 2.10

Resource plugin for Play Framework 2

use it like an amazon s3 bucket. It will only store one version of a file since it computes the sha1 hash of the file and uses that as a pathname.

Add plugin to dependencies

// in you're build.sbt file

val appDependencies = Seq(
	"se.digiplant" %% "play-res" % "1.2.0"

// To simplify the reverse routing we can import the digiPlant namespace
TwirlKeys.templateImports += "se.digiplant._"

Add to conf/application.conf

# Resource plugin save directory
# is relative to app, but can be absolute to filesystem also

Add to conf/routes

GET    /res/:file      @se.digiplant.res.ResAssets.at(file)

# If you wan't to separate your resources into separate sources, you can add multiple routes

GET    /images/:file      @se.digiplant.res.ResAssets.at(file, "images")


Reverse routing

The play-res plugin generates a unique sha1 hash of the file and stores the file on disk in an optimal 4char/4char/sha1hash.ext directory structure. By only having to save the fileuid (5564ac5e3968e77b4022f55a23d36630bdeb0274.jpg) to the db it's easy to retrieve the image or other document.

Here are a few examples on how to get files

<img src="@res.routes.ResAssets.at("5564ac5e3968e77b4022f55a23d36630bdeb0274.jpg")" alt="" />

Or if you wan't to get the route to an file stored in a different source

<img src="@res.routes.ResAssets.at("5564ac5e3968e77b4022f55a23d36630bdeb0274.jpg", "images")" alt="" />

Advanced Usage

You can specify multiple sources if you would like to split you resources into categories, such as profile images / uploads. By then adding another source in conf/application.conf


you will also have to add another route

GET    /profile/:file      @se.digiplant.res.ResAssets.at(file, "profile")
