[Lift] How much Scala knowledge is needed to start coding a simple blog with Lift?
Hi, I have experience with Rails and Java. I'm new to Scala and Lift. I want to ask how much Scala knowledge is needed to start coding a simple blog with Lift? Rails is easy to learn because it require little Ruby knowledge to get started. Having read the Lift book, I feel one must have some advanced Scala knowledge to get started. Could anyone provide some kind of guideline or curriculum of Scala and Lift to get started with Lift? I would like to write a simple blog to learn Lift. But don't know how much Scala knowledge I should have to jump in Lift. Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: net.liftweb.http.LiftFilter is not a javax.servlet.Filter
Hey Ross, Just to close up this thread - you were exactly right. As it turns out, the dependency tree was pulling in a special jetty servlet implementation that I didn't know about. After some dependency management everything worked perfectly!

Hi there, Personally, when I came to Lift over 2 years ago I knew no scala what- so-ever. Knowing scala is a real bonus, but everyone has to start somewhere right? I would suggest just wading in, and see how you get on - there will be a learning curve but this is a very friendly group and has some rich archives full of information to help you on your way.

Hello guys,
I have created a small web service in Lift. It has two services: One

Since I am new to scala and lift, I am thinking the code in Java and
writing in scala, and of course I am having some problems because of
that.
When I read from the Lift service, the service answers correctly,
but
my client method reads one line and ends the loop. I believe that
the

var incomingMsg =

My second problem is when i try to send a message to the API i
receive
the following java error:

var out = new OutputStreamWriter

[Lift] Re: The quality of the Lift list [was: Don't shoot the non-XML messenger ...]
I've been recently really surprised (in positive way) by the Lift community. I also have some experience in maintaining a community and its spirit and i absolutely agree with and support David and his ideas and decisions. Would be really nice to keep the spirit! On Oct 14, 10:49 pm, David Pollak feeder.of.the.be...@gmail.com wrote: Folks, It is not lightly that I ban someone from the group... this is only the second time I've banned a substantive poster. I'm going to discuss some of the process and then touch on some of the substance of the questions that the poster was getting at. The Lift community, reflected on this list, is an inquisitive, friendly place where people who have a passion for building great web apps converge and contribute to making Lift a really great open source framework. Newbies are the lifeblood of the group because they come with fresh perspectives and new ways of looking at things. Questions from newbies help us refine and enhance Lift and the associated documentation. Folks who are building production apps on Lift receive the fastest turn-around because these folks are betting their careers and their enterprises (even enterprises of one) on Lift and they deserve the best support in the industry for taking this risk. A big part of why this community is successful (in terms of size, quality of discussion, and quality of results) is because we keep the quality of discussion high. How do we do this? The folks who have been on the list generally keep the level of discussion to the Lift ideals. We reward newbies with quick answers and encourage friendly discourse. We are generally slower to respond to those that are less reflective of the list ideals. I warn folks who are pushing boundaries (usually privately, but every once in a while publicly) and where the line is. In this case, nothing worked. The poster was neither asking questions, giving usable feedback, or being polite in his engagement with the folks on the list. I received a substantial number of private communications about this poster (which is pretty rare), and I took action. In terms of the substance, let me address to threat issue first. I threatened to ban the poster from the list. Perhaps DHH or Martin would not make such a threat. I am very sure that the quality of discussion on the Lift list is higher than that on the Rails list (one of the reasons I started Lift was to be part of a nicer community.) One cost of having a nicer place is excluding those who do not fit. The second threat I made was to relay a tongue-in-cheek private communication I received about the poster to the list (after receiving the okay from the guy that made the communication to me.) This threat was obvious, using video game rating language http://www.esrb.org/ratings/ratings_guide.jsp, Comic mischief and Cartoon violence. It was something that even a 6 year old can distinguish from reality. Put another way, the poster was talking about Kafkaesque experiences with using Lift and I responded with Jonesianhttp://www.youtube.com/watch?v=CrupqdGvsocfeature=PlayListp=62FED00...language. In terms of the broader issue of Lift's HTML templating system being XHTML only, yes, that's true. Lift treats HTML templates as XML. Lift's templating system is not a String templating system but an XML templating system. This satisfies the needs to render content to HTML browsers. If there are needs for generating other kinds of content, Lift is not as good, but in many cases there are better libraries for doing so. Lift makes it very simple to integrate other rendering/templating engines into Lift, usually with a single line of code the dispatches the HTTP request to an alternate provider of a LiftResponse. If the poster had simply said, I want to template non-HTML output, can you show me how? he would have gotten a nice example (and I might have even rolled it into demo.liftweb.net or maybe Tim might have blogged about it. Keeping things in XML has a number of advantages and a few disadvantages. First, the disadvantages: (1) you can't template non-XHTML responses and (2) everything must be well formed XML. The advantages are (1) security (2) performance (it's easier to cache XML and the cost of mutating XML trees is O(log N)), (3) there is better separation of logic from the view (perhaps Terrance Parr's String Template library achieves this level of separation), and (4) the ability to mutate the resulting page (rewrite tags, move stuff to head/tail, consolidate scripts) is more performant and less error-prone than doing the same with a String-based representation. I will address Bill's security question. For String-based rendering systems that emit HTML, the developer is the one who must make a decision at each insertion point as to whether the incoming String needs to be escaped. Because Strings are untyped, you don't know what they mean, if they're safe to

[Lift] Re: How much Scala knowledge is needed to start coding a simple blog with Lift?
Hello, I bought the Scala book in PDF format (Odersky/Spoon/Venners) and pretty much jumped around it (benefit of PDF is the hyperlinks) for about a week. I am probably proficient with everything in chapters 1-18 which is still pretty much beginner/novice level, but I need the web/book before I tackle most other concepts. But I just wanted to get my hands dirty with a couple of apps and dived straight in. You learn by doing. You learn by reading someone else's code, which is what I've been doing a lot with the Lift sources (I have a local Git clone, and set it up in Eclipse). So, in a nutshell: learn the Scala basics, and get your hands dirty. Open a console and faff about, then start writing apps! :-) What I've done so far can be found here: http://github.com/opyate/Ken http://github.com/opyate/yauser Happy coding!

[Lift] Re: How much Scala knowledge is needed to start coding a simple blog with Lift?
I started Scala 2 years ago by reading the Lift code. so DPPs basically responsible for my Scala code... ;) On Thu, Oct 15, 2009 at 10:58 AM, opyate opy...@gmail.com wrote: Hello, I bought the Scala book in PDF format (Odersky/Spoon/Venners) and pretty much jumped around it (benefit of PDF is the hyperlinks) for about a week. I am probably proficient with everything in chapters 1-18 which is still pretty much beginner/novice level, but I need the web/book before I tackle most other concepts. But I just wanted to get my hands dirty with a couple of apps and dived straight in. You learn by doing. You learn by reading someone else's code, which is what I've been doing a lot with the Lift sources (I have a local Git clone, and set it up in Eclipse). So, in a nutshell: learn the Scala basics, and get your hands dirty. Open a console and faff about, then start writing apps! :-) What I've done so far can be found here: http://github.com/opyate/Ken http://github.com/opyate/yauser Happy coding!

[Lift] ajaxForm and onSubmit
Hi,
I want to use 'def ajaxForm(onSubmit: JsCmd, body: NodeSeq)' and
update a hidden fields value on submit with some value. The problem is
that the generated javascript for the onsubmit event first executes
the serialize on the form and then uses my code for onSubmit.
E.g. ajaxForm(bind(editor, xhtml, hidden - hidden(updateContent
_, , (id, hidden)), save - submit(Save, () = {})),
SetValById(hidden, Str(This should be the content of hidden
This updates the hidden field value after the submit and updateContent
gets only the old value from the last submit. With a normal form it
works without problems with the update code triggered by onSubmit.
Is there a way to update the hidden field before transferring its value?
Thanks,
Tobias

[Lift] Re: DB logging logs statements twice?
OK, I found what's happening. Logging is getting called in the private
DB.runPreparedStatement, and also in the DB.exec method. Mapper uses exec
within the runPreparedStatement call. It seems like exec is the more
appropriate place to be running the logging, since you could have multiple
execs on a prepared statement but you generally wouldn't prepare a statement
without executing it. Thoughts on removing the logging from
runPreparedStatement?

Are they used with any value for 'in' other than the field's own value? In other words, would it make sense to take off the 'in' parameter, satisfying #1 and #2. If you change their signatures, it will break existing code. I probably added them when I needed some helper methods. You're welcome to add companions that read the current is value of the MappedString 2. It would be nice if there was a method like 'is' that would return null as . Actually for my particular use case where I'm testing field.is.isEmpty it would be nice if it would have a method like isEmpty that would return true if value==null || value.isEmpty.

[Lift] Using CalendarMonthView for an Appointment System
Hi all- I am currently attempting to build an appointment calendar in Lift. I'm having a lot of trouble getting everything working correctly (partially i think because of my ignorance of what functionality is available through the js and widgets packages. Currently, on cell click, I open a new window (since for some reason ModalWindow isnt working) that holds an appt template. When that form is submitted, it makes an ajax call to the server, creates an appt and responds. Then the window closes. Then the main page needs to reload, or I need to update the main page's calendar. Nonetheless I have two questions: 1) Has anyone experimented with getting a work appt. system up with this object? Is there an easier way to do this? 2) Would it be easier just to integrate a jQuery plugin into the system and use that (and if so, how would one do that?)

But div stats:options /div gets bound find (but then I, obviously, don't have proper HTML since the options are inside of a div instead of a select). Has anyone else seen this?

[Lift] Another Newbie Question (Last one for a while, Promise!)
After checking the table editor example, I was keen to try it out, and
it works GREAT. So thanks for all of your hard work. Here is my
problem though. I want to filter the table so that only entries
linked to a certain user are displayed.
So for instance say I have class foo:
class Foo extends LongKeyedMapper[Foo] with IdPK {
...
object owner extends MappedLongForeignKey(this, Owner)
}
I want the table to only display the Foo if (Foo.owner ==
CurrentUser.id). I figure I can override the reload (to something
like current = metaMapper.findAll(By) and save methods (to
include the currentUserId) in the ItemList implementation, but then
I'm having trouble conceptually figuring out how to inject my new
extended type back into the TableEditor code, or if this is possible
at all.
Any help would be much appreciated. Thanks in advance.
Dave

[Lift] Re: Using CalendarMonthView for an Appointment System
If you open that ticket the fix will allow you to submit the Ajax request and populate the Calendar without having to reload the page. Page reload for such cases is not very good experience. I opened issue http://github.com/dpp/liftweb/issues#issue/104 to address this. Br's, Marius On Oct 15, 8:47 pm, Dave davidtgoldb...@gmail.com wrote: Marius, I have looked at the docs, and the method I described seemed the best way to do it. I was just curious if there were any other ideas out there. Thanks for the reply. Dave On Oct 15, 12:22 pm, Marius marius.dan...@gmail.com wrote: Calendar Widgets work with JQuery. You can see the demo by going in the lift-widgets project and do a mvn jetty:run. ClaendarMonthView currently handles 3 types of events: itemClick, dayClick, weekClick. Please see the scaladocs of the render method. You can add any JS function for those events. MonthView doesn't have yet a built in system to manage calendars items from javaScript, but we can/should definitely add this. You can open a ticket for this. Other types of calendars like DayView or WeekView have this support. If you have suggestions for improvements please do let us know. Br's, Marius On Oct 15, 6:56 pm, Dave davidtgoldb...@gmail.com wrote: Hi all- I am currently attempting to build an appointment calendar in Lift. I'm having a lot of trouble getting everything working correctly (partially i think because of my ignorance of what functionality is available through the js and widgets packages. Currently, on cell click, I open a new window (since for some reason ModalWindow isnt working) that holds an appt template. When that form is submitted, it makes an ajax call to the server, creates an appt and responds. Then the window closes. Then the main page needs to reload, or I need to update the main page's calendar. Nonetheless I have two questions: 1) Has anyone experimented with getting a work appt. system up with this object? Is there an easier way to do this? 2) Would it be easier just to integrate a jQuery plugin into the system and use that (and if so, how would one do that?)

Personally I'm fine either way, but I think the important question
is what most people find conveys the intent. I wish I would get more
responses to the question! :) One the one hand - goes hand in hand
with - for regular binds, while % doesn't look like an arrow but
it does say attribute in it! Maybe %- ? -% ? %% ?

def keepAttrs(elem: Elem) = (ns: NodeSeq) =

class Keepable(elem: Elem) { def %% = keepAttrs(elem) } implicit def

keepAttrs could actually be implemented shorter:
elem currentNode.map(_.attributes).openOr(scala.xml.Null))
etc.

OK, I found what's happening. Logging is getting called in the private

within the runPreparedStatement call. It seems like exec is the more

execs on a prepared statement but you generally wouldn't prepare a statement

Hello guys,
I have created a small web service in Lift. It has two services: One
reads a row from a table in a database and the other writes one. To
test the API I am writing a small client application in scala to
read
and write from the Lift API.
Since I am new to scala and lift, I am thinking the code in Java and
writing in scala, and of course I am having some problems because of
that.
When I read from the Lift service, the service answers correctly,
but
my client method reads one line and ends the loop. I believe that
the
syntax of my for comprehension is not correct. This is my reader
code:
import java.net._
import java.io._
def read {
val url = new URL(http://localhost:8080/api/getPerson/myrow
)
var connection = url.openConnection
connection.setDoOutput(true);
var in = new BufferedReader(new InputStreamReader
(connection.getInputStream()));
var incomingMsg =
**Loop with the problem***
for (decodedString - in.readLine) {
incomingMsg = incomingMsg + decodedString
}
in.close();
println(incomingMsg)
}
My second problem is when i try to send a message to the API i
receive
the following java error:
java.io.FileNotFoundException:http://localhost:8080/api/getPerson
The error happens when the method tries to read the answers from the
API. This is the code:
def send {
val message =
root
action/action
person
userNameJose/userName
firstNameJose/firstName
lastNamePerez/lastName
passworda/password
emaila...@.com/email
createdon10/12/2009/createdon
createdbyJose/createdby
updatedon10/12/2009/updatedon
updatedbyJose/updatedby
/person
/root
val url = new URL(http://localhost:8080/api/getPerson;)
var connection = url.openConnection
connection.setDoOutput(true);
var outgoingMsg = message.toString
var out = new OutputStreamWriter
(connection.getOutputStream());
out.write(string= + outgoingMsg);
out.close();
***The error happens in the next line**
var in = new BufferedReader(new InputStreamReader
(connection.getInputStream()));
//var decodedString =
for (decodedString - in.readLine)
println(decodedString)
in.close();
}
Any ideas? and, by the way, are there scala packages to replace
java.net and java.io?
Thanks in advance,

[Lift] Re: Another Newbie Question (Last one for a while, Promise!)
I had a similar requirement, so I factored out ItemsListEditor. Subclass it and
override its items with an ItemsList subclass. You can also override title,
onInsert/Remove/Submit, sortFn, and fieldFilter. Actually you have to
override items and title because they're abstract.
Then use the ItemsListEditor instance's edit method as the snippet function.
If you have any other questions please ask!

After checking the table editor example, I was keen to try it out, and

class Foo extends LongKeyedMapper[Foo] with IdPK {

I want the table to only display the Foo if (Foo.owner ==

Generally for people new to scala but with primary intention to explore lift, I suggest the following Get David Pollak's Beginning Scala book, read ch 1-5. (I still think it's a good idea to read ch 6 to know how actors work, but for using lift, you can put it in the back burner.) Then start on lift tutorial. Since you already know java and rails. A bunch of David's comparions to Ruby/Java will feel right at home for you. Also with IntelliJ now have a opensource community edition with scala support. I highly recommend that as a Scala IDE. But for the purpose of learning, The Scala Repl will be enough for exploring. Good luck and have fun.

[Lift] Help obtaining SQL Server version numbers
I don't have access to any SQL Server instances, so I was wondering if
someone out there who does could help me. In order to do some
version-specific behavior in Mapper/Schemifier, I need major and minor
version numbers for SQL Server. I've been googling around, and I found this
doc:
http://support.microsoft.com/kb/321185
I would like to confirm that the major and minor versions returned in the
JDBC metadata matches this document. The attached Scala script can be run to
get the major and minor versions from a particular JDBC connection. Just run
it like:
$ scala -cp your jdbc driver JAR here JDBCVersioner.scala JDBC url
user pass
If you can let me know what the values returned are for your instance, and
what the official name of your version is, that would help me a lot.
Thanks!

[Lift] Problem with RedirectResponse not honoring excludeFromContextPathRewriting
Recently dpp addressed an issue I filed to allow excluding certain
URLs from context rewriting --
http://github.com/dpp/liftweb/issues/closed/#issue/83
However, I think there might be a place that this change missed, or
I'm doing something wrong. Overall, looking at the code I'm not sure
why it doesn't work. The problem is when using RedirectResponse -- it
seems like RedirectResponses are not subject to the new exclusion
check, and I can't figure out where in the Lift code they're being
rewritten.
I have this code in Boot:
LiftRules.excludePathFromContextPathRewriting.default.set(()
= path = {
...
path.startsWith(/login)||

[Lift] Re: Overriding date/time formatting
OK, I'm starting to dig into this and I'm finding that a lot of stuff in
TimeHelpers essentially replicates stuff that's already in JodaTime. Does
anyone see a problem with doing an overhaul of TimeHelpers in addition to
the Mapper stuff? I'll keep the API the same, it should just reduce a lot of
the actual impl code. For example, TimeHelpers.DateExtension exists purely
to allow a Date with a time of 00:00. The code will change from:
def noTime = {
val calendar = Calendar.getInstance
calendar.set(Calendar.HOUR_OF_DAY, 0)
calendar.set(Calendar.MINUTE, 0)
calendar.set(Calendar.SECOND, 0)
calendar.set(Calendar.MILLISECOND, 0)
calendar.getTime
}
to
def noTime = new DateTime().withTime(0,0,0,0)
Actually, I'm not sure that the original code is correct, either, since
DateExtension takes a Date parameter that is never used in the original
code.

[Lift] Re: URL in PlainMailBodyType to BlackBerry
Yes, sure. Most smartphones do, I believe. Now my client informed me as follows. When he receives this message the email view has an option to switch between HTML view and plain text view. When he switches to plain text it does hyperlink the URL. However if I send say an SMS to his email address there's no such choice; it knows it's plain text. So I'm guessing that it's a bug on RIM's part, that multipart messages default to HTML view even if they're plain text. This is on a brand new BlackBerry (5.0). So as a workaround it would be great if Lift would support non-multipart.

I'm fine either way, but I think the important question is what most people
find conveys the intent. I wish I would get more responses to the question!

% doesn't look like an arrow but it does say attribute in it! Maybe %- ?
-% ? %% ?

[Lift] Re: Overriding date/time formatting
OK, more nits to pick. There are two formats in TimeHelpers: hour and time.
They seem very related, so I'm not sure why there's a distinction between
the two. The default for hour is HH:mm:ss and for time it's HH:mm zzz.
Derek
On Thu, Oct 15, 2009 at 1:56 PM, Derek Chen-Becker dchenbec...@gmail.comwrote:
OK, I'm starting to dig into this and I'm finding that a lot of stuff in
TimeHelpers essentially replicates stuff that's already in JodaTime. Does
anyone see a problem with doing an overhaul of TimeHelpers in addition to
the Mapper stuff? I'll keep the API the same, it should just reduce a lot of
the actual impl code. For example, TimeHelpers.DateExtension exists purely
to allow a Date with a time of 00:00. The code will change from:
def noTime = {
val calendar = Calendar.getInstance
calendar.set(Calendar.HOUR_OF_DAY, 0)
calendar.set(Calendar.MINUTE, 0)
calendar.set(Calendar.SECOND, 0)
calendar.set(Calendar.MILLISECOND, 0)
calendar.getTime
}
to
def noTime = new DateTime().withTime(0,0,0,0)
Actually, I'm not sure that the original code is correct, either, since
DateExtension takes a Date parameter that is never used in the original
code.

[Lift] Re: How much Scala knowledge is needed to start coding a simple blog with Lift?
Can you outline the feature set it should have? And what is your time frame? I study Lift in my free time, so basically there's no strict time frame. For a start, I would like to just study enough Scala to be able to use Lift, and just enough Lift to be able to create a simple blog as an exercise. The blog only has 2 resources: user and article. Because I have Java experience and I am working with Erlang full-time now, I am familiar with most ideas of Scala. I just feel that its syntax is too complicated, so for a start I only want to study enough Scala to be able to use Lift. Lift is my final target, Scala is a by- product :D. Thank you all.

[Lift] Re: How much Scala knowledge is needed to start coding a simple blog with Lift?
Ah, like some frameworks like CakePHP have as a basic tutorial? Look on GitHub under examples/hellolift -- it seems to be a blog demo. (In case you're not familiar with the maven layout, the source folder is src/main/scala.) It may be helpful to copy the code from there manually, and try to understand each line one at a time. Although it's not the simplest possible blog; apparently it tries to show off a range of lift's features. - ngocdaothanhngocdaoth...@gmail.com wrote: Can you outline the feature set it should have?

[Lift] Re: Are we willing to make a breaking change for Joda Time?
Oh, I plan on incorporating the DSL. My thought was that JodaHelpers would define most of the same methods as TimeHelpers, just operating on DateTime instead of Date and Calendar. Then you could do import ...Helpers._ import ...JodaHelpers._ and the latter import would mask the TimeHelpers methods. Or you could just import JodaHelpers by itself. Actually, Joda Time has some very nice facilities for doing intervals that would simplify the DSLs a lot and possibly make it richer.

[Lift] Re: edit: What happened to JsonCmd?
The class file names in the jar are determined by the class name / scope / access modifiers and other such nonsense, so unlike java there's not even a vague 1 : 1 correlation between source file names and class file names. So, JsonCmd is in Misc.scala, but it will be emitted as JsonCmd.class (along with HasParams.class, etc). -Ross On Oct 15, 2009, at 10:46 PM, Chris wrote: Well, I pulled all the files from http://scala-tools.org/repo-releases/net/liftweb/lift-util/1.1-M6/ and I do see Misc.scala in lift-util-1.1-M6-sources.jar but not in lift-util-1.1-M6.jar.
