This activator project describes a classic CRUD application with Play 2.4.x, Scala and RethinkDB

---

Building Reactive Play application with RethinkDB

This is a CRUD application, backed by a RethinkDB database. It demonstrates:

• Handling asynchronous results, Handling time-outs
• Achieving, Futures to use more idiomatic error handling.
• Accessing RethinkDB, using Java ReQL command reference.
• Achieving, table pagination and sorting functionality using interactive FooTable plugin.
• Replaced the embedded JS & CSS libraries with WebJars.
• Play and Scala-based template engine implementation
• Integrating with a CSS framework (Twitter Bootstrap). Twitter Bootstrap requires a different form layout to the default one that the Play form helper generates, so this application also provides an example of integrating a custom form input constructor.
• Used Bootswatch with Twitter Bootstrap to improve the look and feel of the application

---

Dependency

---

The rethinkdb-driver is distributed using Maven Central so it can be easily added as a library dependency in your Play Application's SBT build scripts, as follows:

libraryDependencies += "com.rethinkdb" % "rethinkdb-driver" % "2.2-beta-1"

---

RethinkDb

---

• Installing RethinkDB : install
• Installing the Java driver : rethinkdb-driver
• Ten-minute guide with RethinkDB and Java : RethinkDB Java
• Start RethinkDB using rethinkdb command and hit http://localhost:8080/
• Create play_rethinkdb database and table r_employees with default configuration

Usage of RethinkDB Java driver

You can use the drivers from Java like this:

import com.rethinkdb.RethinkDB;
import com.rethinkdb.gen.exc.ReqlError;
import com.rethinkdb.gen.exc.ReqlQueryLogicError;
import com.rethinkdb.model.MapObject;
import com.rethinkdb.net.Connection;

public static final RethinkDB r = RethinkDB.r;

Connection conn = r.connection().hostname("localhost").port(28015).connect();

r.db("test").tableCreate("tv_shows").run(conn);
r.table("tv_shows").insert(r.hashMap("name", "Star Trek TNG")).run(conn);

Please check RConnection.scala and RDatabase.scala

Now Play

---

• The Github code for the project is at : play-rethinkdb
• Clone the project into local system
• To run the Play framework 2.4.x, you need JDK 8 or later
• Install Typesafe Activator if you do not have it already. You can get it from here: http://www.playframework.com/download
• Execute activator clean compile to build the product
• Execute activator run to execute the product
• play-rethinkdb should now be accessible at localhost:9000
