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
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"
- Installing RethinkDB : install
- Installing the Java driver : rethinkdb-driver
- Ten-minute guide with RethinkDB and Java : RethinkDB Java
- Start RethinkDB using
rethinkdb
command and hithttp://localhost:8080/
- Create
playing_rethinkdb
database and tabler_employees
with default configuration
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
- The Github code for the project is at : playing-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 - Employee-Self-Service should now be accessible at localhost:9000
