[Lift] Re: Menu Builder active element
Bjarte, What version of Lift are you using? In the current trunk-head (0.10-SNAPSHOT, which I would strongly encourage using), you can do: lift:Menu.builder li_item:class=foo li_path:class=bar / And the class of the current menu item will be foo and the class of the li's that are in the breadcrumb path to the item will have the class bar Thanks, David Bjarte S. Karlsen wrote: Helo list, Playing around with implementing a already existing design as a lift template.

[Lift] Re: Menu Builder active element
Hello David, I am using 0.9 it looks like. But I can upgrade to 0.10-SNAPSHOT tonight and check out this change. The only thing I have done in the project is to try to adapt the default template so it is no hassle. Thanks for the response. I belive it will solve my problem :) regards, Bjarte David Pollak: Bjarte, What version of Lift are you using?

[Lift] Re: Configuring a lift webapp for https?
Kris, You should be able to run Lift as a Servlet rather than a filter by specifying the net.liftweb.http.LiftServlet in your web.xml file. Try this... if it doesn't work, it's a bug in Lift.

[Lift] A stupid question
I must be very dense, but these cans are kicking my butt (kicking my can?). No matter what I do, I seem to end up with everything back in the can! I just... want... to get... the goodies... OUT! An example: How do I extract the URI of the current page from S.request? I am currently doing something immensely stupid and wrong like this: S.request.toList.head.location.toList.head.createDefaultLink.toList.head.text I *know* this is way wrong, but I'm not clever enough, apparently, to figure out the puzzle, despite reading through the Can code repeatedly. I figure the above works only because what I'm looking for is there, which sort of defeats the purpose of the cans... Can anyone help? This is driving me insane.

[Lift] JPA questions (was Re: SnippetFailure)
A question from the JPADemo...
How does one use this:
def find[A](clazz: Class[A], id: Any) =
em.find[A](clazz, id).asInstanceOf[A]
If I have a User model and I want to use find on the EntityManager, what
goes where the *** is below:
val user = Model.find[User]( ***, userId)
Thanks,
Chas.
Derek Chen-Becker wrote:
OK, let me try to tackle a few of these things at once. First of all,
the hidden element is really just creating a function that is going to
be run when the form is submitted. If you look at the HTML that's
generated you'll see it like this:
input name=F977465725002233_OGX type=hidden value=true /
Basically what happens is that Lift processes form fields as functions.
It looks up the function F977...OGX (in this case) and executes it. I
believe (but am not 100% positive) that forms are executed in the
sequence that they're submitted, which is usually the order in which
they're defined. Anyways, back to the code at hand:
id - SHtml.hidden({category.id http://category.id/ = currentId})
It's going to call the category method (which if you're following the
template is tied to a RequestVar). Since there isn't one already defined
in the request, the default value of the RequestVar is constructed (new
Category()) and returned. That's a big part of the problem with the
current template (and something I'm fixing right now in my wip branch):
we're not really editing the same object, we're making a brand new
object and copying values. The issue is that, as you've found, any
fields that you're not explicitly copying are reset to defaults. What we
probably want to do instead is this:
val ctgy = currentCategory // instead of currentId
...
id - SHtml.hidden(categoryVar(ctgy))
or even
id - SHtml.hidden(categoryVar(Model.merge(ctgy))) // This
automatically re-attaches the category to the entity manager
and then all you'd be required to do in your submit is a Model.flush().
Technically, the flush is implicit once the transaction closes at the
end of the session, but if you have any constraints that you would want
to handle violations on (i.e. a duplicate name, deleting something
that's referenced as an FK), you need to do the flush at that point so
that the exceptions get thrown. Otherwise, the exception is thrown as
Lift is unwinding and your user gets a pretty stack trace.
As for how Hibernate handles object lifecycle, I highly recommend
reading this section of the hibernate EM docs:
http://www.hibernate.org/hib_docs/entitymanager/reference/en/html/objectstate.html
In particular, look at sections 3.1 and 3.6. Most of what we're doing
here is working with detached objects. The merge method is what
reattaches an object.
I realize I'm still waving my hands a bit here and sweeping some
plumbing details under the rug, but I hope this makes more sense now.
Please feel free to ask questions. I'm actually working on the JPA
chapter of the book right now, so you're helping me see where I need to
clarify and explain things better :). I also need to refine the JPA
demo, since the pattern that I'm currently using is non-optimal and even
wrong in cases like yours.

Yeah, I'm really unclear on how this is being passed around and how the
continuation works. For example, what does this line do:
id - SHtml.hidden({category.id http://category.id = currentId})
I can see that it adds a hidden field in the form with the value true
and the name of the field some sort of code. I can only presume that
that code tells the snippet, upon submission of the form, that it should
set the category.id http://category.id to currentId, thus handing
the object back to the
snippet. But how does this really work? What creates the code and what
interprets it and recreates the object? I have been unable to figure
this out.
Also, I'm not entirely clear on hibernate. My understanding is that
there is only one copy of any object, so if I pass the id of an object
that already exists to my category, then I am manipulating the real
object. Is that true? So when I merge, I'm merging changes to that
object into the persisted one?
A problem I'm having because I don't really understand how this works is
that I have a createdAt field in my objects which is a timestamp
that's set to now() when the object is created. But everytime I update
the object, it resets that field to a new now(). And that is true for
other fields as well. I can only guess that the object I'm merging isn't
the same as the object in the database, and the null fields in my new
object cause the fields in the database to be changed to the default
values. That's not what I want, but I can't figure out how to get around
it, and I'm not
[Lift] Re: JPA questions (was Re: SnippetFailure)
You can just do Model.find(classOf[User], userId) and the type on the method will be inferred. Any time you see a Class[A] parameter, it wants the result of a classOf[...].
