Problem with Template constraints

[hideki22]

Hello,

Im using play 2.6.5 and deadbolt 2.6.1 java.

Im trying to add @subjectPresentOr() {}{} but dont work.

im add the import

@import be.objectify.deadbolt.java.views.html.di.{subjectPresent, subjectPresentOr}

but all time say me

Compilation error
not found: value subjectPresentOr

https://deadbolt-java.readme.io/docs/template-constraints

What are doing wrong?

Thanks.

I need to update the documentation, thanks for bringing this to my attention.

In the meantime, this should work

@this(subjectPresentOr: be.objectify.deadbolt.java.views.html.di.subjectPresentOr)

because constraints are now injected into templates (Play 2.6 removed the global state that templates previously relied on). You can see it used in a test here

Ok, I try but another error,

non-static method render(be.objectify.deadbolt.java.DeadboltHandler,play.data.Form<dto.security.UserDto>) cannot be referenced from a static context

I think it was because i use @this to inyect.

@this(subjectNotPresent: be.objectify.deadbolt.java.views.html.di.subjectNotPresent)
@(deadboltHandler: be.objectify.deadbolt.java.DeadboltHandler, form: play.data.Form[dto.security.UserDto])

In the Controller, I use inyector,

public Result loginForm () {
        return ok(views.html.login.render(handler, formFactory.form(UserDto.class)));
    }

And inyect the handler in contructor,

@Inject
    public UsersController(UserDao userDao, FormFactory formFactory, @HandlerQualifiers.MainHandler final DeadboltHandler handler) {
        this.userDao = userDao;
        this.formFactory = formFactory;
        this.handler = handler;
    }

If I delete @this, this error dissapear, but dont work.

Thanks.

@this(...) is used inside Deadbolt's templates because they have required Deadbolt components injected into them.

I think the problem is this:
non-static method xxx referenced from a static context

I think what's happening, without seeing your code, is that you're not injecting your own components into your controllers. Take a look at this guide to see how to do this.

Yes, this is the problem... I forgot inyect the view. Now work perfect.

Thank you so much.

Thanks - I'll update the docs as soon as I have chance.

Two items:
@this(subjectPresent: be.objectify.deadbolt.java.views.html.di.subjectPresent, subjectPresentOr: be.objectify.deadbolt.java.views.html.di.subjectPresentOr)

(I don't see this in the doc)

This shows how to have two items, as opposed to just one. From here on (three, four items) it's self-explanatory.

Actually, it's interesting how so often documentation shows how to do something with ONE item, or with TWO items, but never both, when really both are needed. But that's just a pet peeve of mine.
