Question

I am new to the play framework (I use the Java version). I am looking for a solution to add a selected=”selected” to a field. My code:

@select(settingsForm("projectManager"), options(projectManagers), '_label -> "Project manager" )

The HTML result looks like:

<select id="projectManager" name="projectManager">   
    <option value="222">Henk</option>
    <option value="96">Geert</option>
</select>

Does anyone know the scale argument of the @select field to add the select=selected to the html? The result i am looking for looks like:

<select id="projectManager" name="projectManager">   
    <option value="222">Henk</option>
    <option value="96" select="selected">Geert</option>
</select>

After searching the web for some time, my thought went to the sample projects. The answer was there, right in front of me. Creating only the form with a view is not enough! To make this clearer, just look at the computer-database example. To create a empty field, you just pass a Form object to to the view:

Controller:
public static Result create() {
    Form<Computer> computerForm = form(Computer.class);
    return ok(
        createForm.render(computerForm)
    );
}

View:
@inputText(computerForm("name"), '_label -> "Computer name")
@inputText(computerForm("introduced"), '_label -> "Introduced date")
@inputText(computerForm("discontinued"), '_label -> "Discontinued date")

If you want the Form to be filled, you need to pass data to that Form. As the example shows:

 public static Result edit(Long id) {
    Form<Computer> computerForm = form(Computer.class).fill(
        Computer.find.byId(id)
    );
    return ok(
        editForm.render(id, computerForm)
    );
}
