如何使用FormClass？ [PlayFramework]

Question

如何在Result A conversationForm中使用B类？

public static Result A() {
    Form<Conversation> conversationForm = form(Conversation.class).bindFromRequest();
    return TODO;

}

public static Result B() {
    //I want this 
    //return(abc.render(conversationForm);
}

Answer 1

form(T)有方法fill(Object)，因此您可以使用某个对象

填充它

public static Result B() {
    Conversation conversation = Conversation.find.byId(123);
    Form<Conversation> conversationForm = form(Conversation.class).fill(conversation);
    return(abc.render(conversationForm);
}
