[Lift] Re: jpa, emf Model and unit tests

Also, if you use Hibernate, you can use:

*Session.createFilter*(city.getAddresses(), "where this.name like
'S%'").list();

[Lift] Re: jpa, emf Model and unit tests

[Derek Chen-Becker]

OK, for one, the bidirectional mapping adds no cost in terms of DB access
other than the time it takes you to write it. Collections are lazily loaded,
so unless your code *retrieves* City.addresses, the database never gets hit.
JPA is really not designed with the concept of entities having access to the
EntityManager that loaded them, although there may be some provider-specific
way to get at it. Unfortunately, you're on your own if you want an entity to
obtain other entities via queries or some other non-relationship means.
Generally, if you need that kind of coverage you should do it through logic
code that can glue things together instead of tying it to your entities.
After all, I'd argue that if the logic isn't part of what you can express in
the database then it doesn't belong in the entity classes anyways. When you
say "bogged down in bidirectional mappings" are you referring simply to the
overhead of adding the mappings to your entities, or do you think that
there's some performance issue with bidirectional mappings (AFAIK, there
aren't any).

[Lift] Re: Javascript "confirm(..)" dialog with ajaxButton

[Chris]

Hi Tim,
just one addition. Wicket has something called an ajaxcall decorator
(IAjaxCallDecorator) that allows you to modify the script and more
specifically the "decorateScript" method allows you to prepend a char-
sequence to the script. This would allow me to do exactly what I want.
Is there any way in Lift to achieve the same thing? I'd really like to
avoid dealing with JavaScript directly apart from something as trivial
as the "confirm(...)" dialog or similar.
Cheers, Chris.

[Lift] Re: Javascript "confirm(..)" dialog with ajaxButton

[Chris]

Hi Tim,
not sure if I really got across what I need. I need the AJAX
functionality in this case as I'm displaying a large amount of data in
a table and would like to allow the user to delete individual records
without the refresh problem of having the button cause a POST. I also
need to make sure the user hasn't "accidentally" pressed "delete",
hence the "confirm(..)" dialog. Does option (1) above prevent the
subsequent call of the ajaxButton if the user presses "cancel" on the
JS "confirm" dialog, but allow it if he presses "OK"? Option (2) is
just a slightly different way of doing what I've already tried (I
added the "onclick" attribute to the ajaxButton call itself) and this
subsequently removes the actual AJAX call itself.
Thanks, Chris.

[Lift] Re: jpa, emf Model and unit tests

[TSP]

There are two questions here. I don't really want to get bogged down
in bidrectional mappings I was rather hoping for suggestions on how my
domain objects might simply get at the right Model transparently from
both application and junit (in Grails it was done with Spring
injection - here perhaps an EMF factory (a factory-factory?)) However,
in answer to the bidirectional mapping question here is an example:

class City {
  var name: String;
  var population: Int;
  //  var addresses: java.util.Set[Address]  // BAD because London has
approx 3m addresses

}

class Address {
name, street etc
var city: City
}

object Address {
def matchAddress( .. unstructured input strings from ERP
system ...)  = {
,,,
Some[Address]
  else
None
   }
}


class Organisation {
var hq: Address;
}

So I can easily trace from organisation to it's address and then find
out if the organisation is in a big city.
But I never need to directly fetch the city and iterate through the
addresses.

There are many more examples where the many side of things runs into
hundreds and thousands (shipments to a daily customer over the last 2
years, tracking events on trucks at 1 minute intervals stored for 6
months).

Again with reference to Evans Domain Driven Design for a large and
complex domain model (I expect to end up with well over 50 objects)
universal bi-directional mappings are strongly discouraged (see for
example discussion on p. 83)

Now you might argue that my address matching should be delegated to a
service, but the techniques can be quite country specific tying in the
postcodes and town names for example or dealing with peculiarities
(from my point of view) of US street naming conventions - so I want my
address matching tied closely to may data objects (in that case it
would be Address subclasses).  Also as soon as I do get rid of bi-
directional mappings then any direct business logic that requires
traversal in the "missing" direction can be readily accomplished by
access to the database.

[Lift] Re: Javascript "confirm(..)" dialog with ajaxButton

[Timothy Perrett]

Hey,

Seems like you have a couple of options...

1. you could just write normal javascript irrespective of lift and
just put that in a JS file like normal. Something like:

$('#mybutton').click(function(e){
  confirm... //blah blah code here
});

2. If you *really* want to use the on-click handler (personally I
wouldn't) then you could do somethig like this in your snippet:

SHtml.ajaxButton("submit", () => println("badger")) % ("onclick" ->
"confirm();")

I would highly recommend using option one as the functionality is
purely a client side concern in that sense and nothing to do with
lift. Does that help?

Cheers, Tim

[Lift] Javascript "confirm(..)" dialog with ajaxButton

[Chris]

Hi there,
I'm pretty new to Lift and Scala for that matter, but have long been
on the lookout for something like seaside running on the JVM and this
is just great! Now to my issue...
I've hit a brick-wall in the attempt to get a confirmation dialog
working before executing an ajaxButton. I've tried adding an "onclick"
attribute to the ajaxButton call, but that only seems to replace the
AJAX call itself rather than say prepending the call with the contents
of the "onclick" attribute. I'd like to implement a "delete" button
with a confirmation dialog. I've looked at ModalDialog, but due to my
inexperience and lack of examples haven't found a way of achieving
this. Could someone enlighten me as to how I could implement this?
Cheers, Chris.

[Lift] Re: slicing off a web front end

[Derek Chen-Becker]

Could you give me some sample ajax urls? This looks like it should be pretty
simple but I'm still a little lost in Rails.

 Hmm Id tend to agree – you’d probably have to rewrite a lot of the JS
 away from prototype if your using RJS but from a migration POV, I think the
 main issue will be translating some of the rails black-box magic to, as
 Derek says, JsonResponses etc.

 If you provide a bit more context that would be splendid.

 Lifted,

 After diving into what it takes to more or less auto-generate a decent
 starting point for a midtier from the backend of a RoR (or other) website,
 i'm now interested in the least painful way to slice off the frontend of an
 existing website and paste it onto a lift(ed) midtier.

 Suppose i've got an existing RoR-based application with a relatively
 sophisticated AJAX frontend and i want to do minimal messing about with the
 front end. What is least i could do to have the existing frontend-generated
 requests end up in a lift handler?

 i can provide links to an existing code context if that will facilitate
 discussion.

[Lift] Re: jpa, emf Model and unit tests

I may be misunderstanding this, but if you just do bidirectional mappings in
JPA then the DB query is generally efficient and transparent. Could you post
a little snippet showing what you're trying to do?

The Eclipse plugin uses a different version of Scala than does Lift.  There

Weird thing is  that I'm able to mock "MetaTeam":

---
trait MetaTeam extends Team with LongKeyedMetaMapper[Team] {

}

object Team extends MetaTeam {
  def findByUser(user:User): List[Team] =
UserTeam.findAll(

  OrderBy(UserTeam.team, Ascending)).map(_.team.obj.open_!)

[Lift] malformed Scala signature of User

[erik.karls...@iki.fi]

Hi,

I have set of specs test and I'm using mockito

I noticed that if I have a list of Users (pretty much same class that
is coming from archetype) and do following test:

users(1).firstName must beEqualTo(name2)

Then I get :
[WARNING] Exception in thread "main" java.lang.RuntimeException:
malformed Scala signature of User at 13798; reference type _5 of
 refers to nonexisting symbol.

If the line is changed to:

(users(1).firstName == name2) must beTrue

it compiles really nicely. Based on previous posts here it seams to be
that this is scala bug (I use 2.7.4|3)

Much bigger problem for me is that when trying to mock the User:

var userDbMock = mock[MetaUser]

causes the same issue:
[WARNING] Exception in thread "main" java.lang.RuntimeException:
malformed Scala signature of User at 13798; reference type _5 of
 refers to nonexisting symbol.

MetaUser is trait:

object User extends MetaUser {

  override def dbTableName = "users" // define the DB table name
  override def screenWrap = Full(
   )
  // define the order fields will appear in forms and output
  override def fieldOrder = List(id, firstName, lastName, email,
  locale, timezone, password, textArea)

  // comment this line out to require email validations
  override def skipEmailValidation = true
}

trait MetaUser extends User with MetaMegaProtoUser[User]  {

}

Have anybody encountered similar problem when mocking or even found a
workaround for this case?

br,
- Erik

PS. Weirdest thing is that I'm able to run the test cases in
Eclipse...

[Lift] Re: jpa, emf Model and unit tests

[TSP]

Viktor,
It's a valid point, and I would where possible but I've got quite a
lot of uni-directional references (for example, addressable locations
in a city) where using a mapping would entail very large fetches that
are better handled by querying the database. Evans in Domain Driven
Design is very keen on uni-directional references and who am I to
argue :-)

[Lift] Re: jpa, emf Model and unit tests

[Viktor Klang]

Why don't collection mappings work?

Also, from personal experience, mixing persistence-logic in domain objects
does make you feel somewhat naughty.

Good ... well then shouldn't the same rationale be applied for
 since with-param is not really a snippet invocation?

perhaps for lift tags that are not really snippets to use:




?

[Lift] jpa, emf Model and unit tests

[Tim P]

Hi
I'm looking for some guidance here and I don't think this is addressed
in the book.

I've got domain classes that need to go get stuff from the database
"list all ... " type of methods.
So presumably my domain class should have, or be allowed to have
methods that access Model
But my unit tests need to test these methods. So I need a model which
is instantiated within the test environment and so does not need to be
extended with RequestVarEM which presumably would be a bad thing
(though perhaps it's harmless).
Any suggestions on "best practice" to achieve this? (I'm still very
much trying to find my way round natural scala constructs)

Should it be mentioned in the jpa chapter in the book?

Tim

The only thing that's being changed is  (which looks like a
snippet invocation) to something like: 

It's a syntactic change that has no semantic difference.

Any of the .html templates are processed by Lift's standard XHTML render
pipeline.  This pipeline renders XHTML.  While there are options for setting
the XML headers, etc., this mechanism is primarily for creating XHTML pages
for the browser to consume.

If you want to render XML, JSON, etc., you need to create a custom
dispatcher.  You can see an example result at:

http://demo.liftweb.net/webservices/all_users

You can look through the Lift source in sites/example.  Start in Boot.scala
and work from there.

I'm currently working on revising this code, so give it a day or two and
you'll see cleaner examples rather than code that's 2 1/2 years old. :-)

You'll find pattern matching is a much easier way to route URLs because you
have the full power of the language at your disposal, but a nice declarative
syntax:

LiftRules.dispatch.append(NamedPF("Web Services Example") {
case Req("webservices" :: "all_users" :: Nil, _, GetRequest) =>
  () => Full(all_users())

This intercepts the /webservices/all_users GET request and has it serviced
by the all_users() method.

Thanks,

David

[Lift] Re: Feedback on screen cast, please

[Meredith Gregory]

David,

Your screencast is very well done. There is one small change i would make to
add a layer regarding the management of complexity. Make a change to the
app: a small but noticeable change, like reorder the messages newest to
oldest with a timestamp, or something. It would be ideal if somewhere in
your modification you commit an error that is subsequently caught by typing.
These two basic points dovetail nicely into a crucial point that Bill
Venner's makes in his JavaOne presentation: types don't prove your program
correct; types prove changes to your program correct. i think you could
increase the bang-for-buck by a factor of 2 while only adding 15 - 20 secs
to the time.

Best wishes,

--greg

browser.

Look at the lib.PageChunkServer.scala file to see how it's done.

Thanks,

David

BTW ... I'm not sure why you'd prefer an XML response back instead of
JSON or JavaScript ... but it's up to you.

[Lift] Re: How to set different response in lift

[marius d.]

Of course ...  You can use:

1. DispatchPf functions and return an XmlResponse
2. Try this:

  def ajaxButton(text: NodeSeq, func: () => NodeSeq, attrs: (String,
String)*): Elem = {
attrs.foldLeft(fmapFunc(NFuncHolder(func))(name =>
{text}))(_ % _)
  }

When processing Ajax requests lift automatically recognizes, JsCmd,
NodeSeq, JsCommands, LiftResponse. So Instead of func: () => NodeSeq
you could also say func: () => LiftResponse and have your function to
return an XmlResponse. But NodeSeq seems easier to me.

[Lift] Getting started: No XML output, docs and basic restful CRUD (on GAE)

[Tom]

Hello List,

I just started with Scala and Lift. Installation was pretty straight
forward (I only had to fight with Debian SIDs Java .. it needed
OpenJDK instead of what is provided as default. Maven threw exceptions
with gnuJava)
So far I read one book about Scala and I looked at a few howtos on the
lift website.
Looking at all the things Maven2 downloaded nearly scared me a little,
but it seems to be very powerful, so it might be nice.
I played around with a few examples and I am trying to get text only
output. I deleted the template and removed nearly everything from the
index.html, but I still get the XML header in the output. I just want
my own text.

I guess I have to replace surround in  with something
else. But where do I find the docs for those options?

My goal is to have basic restful CRUD operations on GAE. But what I
could really use is a small piece of code for the get, put, delete and
post messages(preferably with database connection.)
The way I learn new languages and frameworks is to embrace and extent
a piece of code that very roughly does what I want (very
Microsoftish).
So maybe someone has done ROR like CRUD on GAE and is willing to share
his code?
(Or maybe restful CRUD is not the way I should use Lift .. As I said I
am still very new to functional programming and Scala+Lift.)

Thanks!

[Lift] Re: Feedback on screen cast, please

[James Strachan]

Great stuff!

The only thing I can think of that could be improved is maybe
mentioning the JavaRebel stuff; when seeing Rails demos, there's no
stop-start-wait-30 seconds type stuff while maven does its thing -
maybe in the next screen cast the JavaRebel stuff could be shown so
that the same rails-ish RADness is possible.

[Lift] Re: Upgrade to 2.7.4 breaks "with-param"?

[marius d.]

I'm not referring to something similar to lift:bind. Just that using
snippets or Loc snippets, chooseTemplate etc. gives you the ability to
to change content depending on what page you are which is with-param
kind of does.

No worries, these are valid question and to me it kind of boils down
to the style of designing the lift template cause there is quite a bit
of flexibility provided so things can be done in many ways.

So I guess it needs to be determined what would replace 
(if it will be replaced).

Personally I really don't mind  ... :)

Br's,
Marius

Can you be specific about which other lift artefacts you want to replace
lift:bind with? Im not fighting lift:binds corner or anything, rather, just
interested to know what will supersede it because this kind of functionality
is key in our template strategy.

Right now: bits me ... perhaps Dave has more input. However it seems

can be easily done without it using the other Lift artifacts. Still
probably people got used with  style and finds this pretty
