How to get "Slick Direct Embedding" on your computer

There are several ways to get this template.

Option 1: Choose slick-direct in the Typesafe Activator UI.

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

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

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

  1. Download the Template Bundle for "Slick Direct Embedding"
  2. Extract the downloaded zip file to your system
  3. The bundle includes a small bootstrap script that can start Activator. To start Typesafe 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\slick-direct> activator ui 
    This will start Typesafe Activator and open this template in your browser.

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

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

Option 4: View the template source

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

Introduction

This tutorial shows you how to use Slick's experimental Direct Embedding query API.

The Direct Embedding requires access to the Scala compiler at runtime. It is declared as an optional dependency in Slick's POM file, so it won't be pulled in automatically when you add a dependency to Slick to your build. You need to add the Scala compiler explicitly, as done in this project's build.sbt file:

libraryDependencies +=
  "org.scala-lang" % "scala-compiler" %
  scalaVersion.value

The sample app can be found in SimpleExample.scala. This application automatically runs when Activator is started and then re-runs after every successful compile. You can see the output in Run.
