Lightbend Activator

Play Slick quickstart

Activator will be EOL-ed on May 24, 2017.

We’re making it easier and simpler for developers to get started with Lightbend technologies. This unfortunately means that future releases of Play, Akka and Scala will no longer include Activator support, and Lightbend’s Activator server will be decommissioned by the end of 2017. Instead of supporting Activator to create and set up development projects, we'll be supporting standard Giter8 templates for sbt users and Maven archetypes for Maven users. So going forward,

To create new Lightbend projects

Instead of using the Activator command, make sure you have sbt 0.13.13 (or higher), and use the “sbt new” command, providing the name of the template. For example, “$ sbt new akka/hello-akka.g8”. You can find a list of templates here.

Also, as a convenience, the Lightbend Project Starter allows you to quickly create a variety of example projects that you just unzip and run.

To create new templates

If you want to create new templates, you can now do that in Giter8.

To migrate templates from Activator to Giter8

If you created Activator templates in the past, please consider migrating them to Giter8 with this simple process.

Activator template for Play Framework and the Slick database access library. This template helps building a classic Web app or a JSON API.

How to get "Play Slick quickstart" on your computer

There are several ways to get this template.

Option 1: Choose play-slick-quickstart in the Lightbend Activator UI.

Already have Lightbend Activator (get it here)? Launch the UI then search for play-slick-quickstart in the list of templates.

Option 2: Download the play-slick-quickstart project as a zip archive

If you haven't installed Activator, you can get the code by downloading the template bundle for play-slick-quickstart.

  1. Download the Template Bundle for "Play Slick quickstart"
  2. Extract the downloaded zip file to your system
  3. The bundle includes a small bootstrap script that can start Activator. To start Lightbend Activator's UI:

    In your File Explorer, navigate into the directory that the template was extracted to, right-click on the file named "activator.bat", then select "Open", and if prompted with a warning, click to continue:

    Or from a command line:

     C:\Users\typesafe\play-slick-quickstart> activator ui 
    This will start Lightbend Activator and open this template in your browser.

Option 3: Create a play-slick-quickstart project from the command line

If you have Lightbend Activator, use its command line mode to create a new project from this template. Type activator new PROJECTNAME play-slick-quickstart on the command line.

Option 4: View the template source

The creator of this template maintains it at https://github.com/loicdescotte/activator-play-slick#master.

Option 5: Preview the tutorial below

We've included the text of this template's tutorial below, but it may work better if you view it inside Activator on your computer. Activator tutorials are often designed to be interactive.

You've just created a simple Play Framework application with the Slick library!
This template will help you building a classic Web app or a JSON API.

View the App

Once the application has been compiled and the server started, your application can be accessed at: http://localhost:9000

Slick Usage

In order to enable schema generation you can specify the packages or classes you want to have in the application.conf file. The default value is :
 slick.default="models.*"

It follows the same format as the Ebean plugin: slick.default="models.*" means all Tables in the models package should be run on the default database. It is possible to specify individual objects like: slick.default="models.Users,models.Settings"
The DB wrapper provided by play-slick is just a thin wrapper that uses Slick classes with databases defined in the Play Application . To see an example, check the Application.scala file from this template. Using "import play.api.db.slick.Config.driver.simple._" will import the driver defing with the key "db.default.driver" in application.conf, or the one set by the test helpers in test mode (see tests in this template as an example).

Execution context configuration

You may want to use a separated execution context to avoid blocking threads in the default thread pool. Play-slick provides a DBActionto handle this. This thread pool configuration is available in application.conf (see the slick-context settings)
If you need to use more advanced use cases (example : more than one database driver per mode (run or test)), please read the play-slick wiki.
