formFactory.form() doesn't exist ! PlayFramework

Question

I've a little problem, i want to create a web app and i learn PlayFramework with java documentation of

This sample code :

public Result hello() {
    DynamicForm requestData = formFactory.form().bindFromRequest();
    String firstname = requestData.get("firstname");
    String lastname = requestData.get("lastname");
    return ok("Hello " + firstname + " " + lastname);
}

The ''formFactory'' doesn't exist.

From the documentation:

To wrap a class you have to inject a play.data.FormFactory into your Controller

Play already knows about FormFactory, so just add a constructor parameter for it:

public class FooController {

    private final FormFactory formFactory;

    @Inject
    public FooController(final FormFactory formFactory) {
        this.formFactory = formFactory;
    }

    public Result hello() {
        DynamicForm requestData = formFactory.form().bindFromRequest();
        String firstname = requestData.get("firstname");
        String lastname = requestData.get("lastname");
        return ok("Hello " + firstname + " " + lastname);
    }
}

I'm guessing the Model you mention is that of EBean. You need to enable EBean for your project, and then you'll have the necessary classes on your classpath.

In project/plugins.sbt:

addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "3.0.0")

build.sbt:

lazy val myProject = (project in file(".")).enablePlugins(PlayJava, PlayEbean)

More information is available in the relevant docs.
