Issue with bindFromRequest in Play! Framework 2.3

Question

I\'m trying to use the automatic binding feature of Play, without success. I\'m developing in Java, on Eclipse 4.4 Luna.

Here is my form :

There is absolutely no link between the binding and your database. Do not follow @blackbishop's advice telling you to change all the fields of your model to String. That's a very bad idea, if there are different types, there is a reason...

Moreover, Ebean (supposing you're using it) or JPA generate database column types according to your Java properties type. Why would you store a 0 or a 1 in a varchar column ?

Follow these rules :

1. Use a singular name for your models (User instead of Users)
2. Always use camel case for your properties, no underscores (firstName instead of first_name, lastName instead of last_name...)
3. Check errors before getting the value after binding

That should give you this :

public static Result createUser() {
    Form form = Form.form(User.class).bindFromRequest();
    if (form.hasErrors()) {
        // Do what you have to do (i.e. : redirect to the form with a flash message)
    }
    User u = form.get();
    u.save();
    return redirect(routes.Backend.allUsers());
}

By the way, in your testing lines, the user_id is correctly generated because you have no validation rules and this data comes from the database, not the form.
