Book for the Lift Web Framework

Derek, Marius and I, with the help of the community, will be putting together a comprehensive book for using Lift.

We have set up a Google Group for topic discussion here: http://groups.google.com/group/the-lift-book

liftbook's Issues

Unclear that we shouldn't be developing alongside PocketChange

I'm trying to wrap my head around Lift, so I began reading the book. First off, way to go. This is the only complete and accessible lift introduction that I've found on the internet.

However, I found myself lost during the Pocket Change chapter (Chapter 2). I was trying to develop alongside the example, which was a failing proposition because a fair amount of code necessary to make the project compile was not there! For example, the code for the Account model object references these symbols AccountAdmin and AccountViewer which are never implemented, brought up again, or explained during the entire rest of the book.

Only by looking at the git source was I able to make the model compile and continue to code alongside the tutorial.

Calculating Locale Based on Cookies invalid characters (fix code)

In http://exploring.liftweb.net/master/index-D.html in the end of file part "Calculating Locale Based on Cookies and Parameters" code

wrong code character : replace ’-’, ’’ with ’-’, ’’ and remove invisible illegal characters. fixed code:

// Properly convert a language tag to a Locale
def computeLocale(tag : String) = tag.split(Array(’-’, ’_’)) match {
  case Array(lang) => new Locale(lang)
  case Array(lang, country) => new Locale(lang, country)
  case Array(lang, country, variant) => new Locale(lang, country, variant)
}

// Define this to be whatever name you want
val LOCALE_COOKIE_NAME = "SelectedLocale"

LiftRules.localeCalculator = {
  case fullReq @ Full(req) => {
    // Check against a set cookie, or the locale sent in the request
    def currentLocale : Locale =
      S.findCookie(LOCALE_COOKIE_NAME).flatMap {
        cookie => cookie.value.map(computeLocale)
      } openOr LiftRules.defaultLocaleCalculator(fullReq)

    // Check to see if the user explicitly requests a new locale
    S.param("locale") match {
      case Full(requestedLocale) if requestedLocale != null => {
        val computedLocale = computeLocale(requestedLocale)
        S.addCookie(HTTPCookie(LOCALE_COOKIE_NAME, requestedLocale))
        computedLocale
      }
      case _ => currentLocale
    }
  }
  case _ => Locale.getDefault
}

Listing 3.6: A Complex Rewrite Example

In Listing 3.6, A Complex Rewrite Example:

val rewriter : PartialFunction[RewriteRequest,RewriteResponse] = {
  case RewriteRequest(ParsePath(username :: Nil, _, _, _),
      DeleteRequest,
      httpreq)
      if isMgmtSubnet(httpreq.getRemoteHost()) =>
    RewriteResponse(deleteUser :: Nil, Map(username -> username))
}
LiftRules.rewrite.append(rewriter)

Should probably be:

val rewriter : PartialFunction[RewriteRequest,RewriteResponse] = {
  case RewriteRequest(ParsePath("username" :: Nil, _, _, _),
      DeleteRequest,
      httpreq)
      if isMgmtSubnet(httpreq.getRemoteHost()) =>
    RewriteResponse("deleteUser" :: Nil, Map("username" -> username))
}
LiftRules.rewrite.append(rewriter)

Possible error in: "Coordinating Between Multiple Comet Clients"

Hey guys,

I think I've stumbled upon an error in the book on page 157. I think you're missing the override keyword on the methods localSetup and localShutdown

Thanks,
Mads Hartmann

REST chapter to cover what has been added in Lift 2.0

The lift 2.0 release notes speak of a "Powerful, concise REST support" and all that is to show for it is the documentation on assembla. I am interested to see how the "new" functionality fits into the demo application of the book.
https://liftweb.assembla.com/wiki/show/liftweb/REST_Web_Services

Add docs on Menu.builder level and expand options

Add it to the Wiki, too

Comet Sample in Pocketchange

Add Comet samples to sample app - possibly using shared accounts and watching others update.

Add Tyler's flow charts on Lift porcessing

See http://groups.google.com/group/liftweb/browse_thread/thread/8a7276f02a26d893

google map api error

hello

I want set google map api.

ex) ＜script src="http://maps.google.com/maps?file=api&v=2&sensor=true_or_false&key=ABQIAAAAbatLJBm-S8hZ??????????Kjn5hrRSDxT3TEkaetXhQ1WV8hEqirn9k6T7JkK77gvngPOQ" type....

but.. this script set is error.

I want to easily solve this problem,

But, I did not find the solution of this problem.

Please teach a solution.

thank you.

Add SiteMap DSL coverage

Cover some examples and maybe start a 2.0 version of PocketChange to demo the features

typo listing 4.1

entry.amount should be entry:amount

Provide detailed coverage of Snippet dispatch

This needs to explain not only how reflection-based dispatch works, but how to do explicit dispatch as well as session- and request-based dispatch

Complete section on Lift tags

Added a whole bunch based on code review, but need to fill them all in

Lucene/Compass Integration

I'm interested in how this works, I'm assuming it's xml but an example is welcome.

Cover new I18N support (XML based)

Should add into existing appendix

Section 1.1 : Typo

For those of you have experience

should be

For those of you who have experience

Cover ManyToMany in addition to HasManyThrough

Cover new 2.2 stateless mode

2.2 will support serving specified paths in stateless mode, with warnings if you try to use state

Update Section 4.6 Head and Tail Merge for HTML5

Section 4.6 Head and Tail Merge should be updated to include a description of the < head_merge > tag required for merging to work correctly when using HTML5.

Issue Number 1 is just a test.

This is a test of the emergency issue tracking system.

Typo in sourcecode C.3 ActorPing

ActorPing.scheduleAtFixedRate(myActor, MyMessage, 0 seconds, 15 secods) <-- secods

should be seconds i guess :) with an "n"

http://exploring.liftweb.net/master/index-C.html

Add section on unit testing

In particular, show how to manually set up S, LiftSession, etc.

Update logging appendix for new slf4j changes

Now you need to specify which slf4j backing API will be used

Revise custom Loc

Lots of stuff changed between 1.0 and 2.0

Coverage of AjaxForm

In chapter 9, there is some explanations and examples for individual ajax components but it would be really helpful if there was some explanation and an example with template and snippet using an AjaxForm - something similar to what is at the beginning of chapter 4 for regular forms.

Improve I18N coverage

Among other things:

• Provide a more complete LiftRules.localeCalculator example
• Show a complete example of how to bundle the Properties files
• Show how to use MessageFormat (or S.? ?)

See http://groups.google.com/group/liftweb/browse_thread/thread/7a37f4dadf649689 for more details

Section on StreamingResponse is wrong

You need to know length ahead of time, so the example (currently Listing 9.4) is wrong.

Listing 2.2 Pocket Change Account Entity. Error in import of Empty

When using Lift v2.3 with Scala 2.8.1, the class Empty is declared in net.liftweb.common package and available in lift-common_2.8.1-2.3. In Listing 2.2 the third import should be import _root_.net.liftweb.common.Empty instead of import _root_.net.liftweb.util.Empty

Misprints in 13.5

In

"It is developer by Jabber [E]  [E] http://xmpp.org/about/jabber.shtml open-source community. Lift provides an XMPP dispatcher implementation that you application can use to receive instant messages, manage rosters etc."

looks like "developer" should be "developed" and "you application" should be "your application".

issues starting up PocketChange app in Tomcat

Hello:
I'm trying to start up PocketChange in Tomcat (version 6.0.24). I downloaded the version from http://github.com/tjweir/pocketchangeapp/tree on Feb 01, 2010.

When I try starting up using "mvn jetty:run" it's all fine. But when I deploy the WAR using Tomcat. I get the following error upon starting. The "SEVERE" debug statements repeat forever. Please advise on how I can use Tomcat for my development instead of Jetty.

PS: The other problem with this behavior is that eventually it starts throwing "Out-of-memory" errors and the whole JVM comes to a slow death.

Any advise?

Additional Data >>>>>>>>>>>>>>>

I also tried to create a H2 DB outside of PocketChange and point it to that by modifying the DriverManager.getConnection in Boot.scala
From:
val dm = DriverManager.getConnection("jdbc:h2:pca_example")
To:
val dm = DriverManager.getConnection("jdbc:h2:tcp://localhost:9092/C:/db/PocketChangeDB", "admin", "admin")

After deploying the new WAR it to Tomcat. Here's what I'm getting now. No more continuous repeating errors and no "out-of-memory" issues. But when I bring up the app. I see the following message on interface:

"No Navigation Defined." and there are no options available to do anything.

Jetty plugin example code needs revised

Per http://groups.google.com/group/the-lift-book/browse_thread/thread/7d6ddd29d2aa3cb0?hl=en

I hade to add the plugin group

 <pluginGroup>org.mortbay.jetty</pluginGroup>

as posted here: http://docs.codehaus.org/display/JETTY/Maven+Jetty+Plugin.

The failure message I got before was:
The plugin 'org.apache.maven.plugins:maven-jetty-plugin' does not exist or no valid version could be found

Maybe someone wants to add this hint to the book?

Add section on LiftSession

There is some really useful stuff in LiftSession (the onSessionX event callbacks for example) but there is little or documentation discussing the class, the callback lists, when they get called or appropriate strategies for how and when to use them. For example: what the heck does it mean to "passivate" a session?

Incorrect Description of MetaMapper.fieldOrder

Hi,
Not sure if you saw this thread in the Lift group recently, but I made the point that I noticed behaviour that contradicted what was described in Exploring Lift:

"If you don’t want a particular field to show up in forms or XHTML output, simply omit it from the fieldOrder↓ list." (http://exploring.liftweb.net/master/index-8.html#toc-Section-8.1)

DPP replied with:

"Actually, Exploring is wrong about this. The field order defines the order the fields will be displayed, but if a field is not listed in field order, it will be displayed in an undetermined order after the ordered fields have been displayed. This particular feature goes back to pre-Lift Mapper."

Tweaks neeed in section 3.7

Per http://groups.google.com/group/the-lift-book/browse_thread/thread/da4d7c7cb6d79547?hl=en

• The last sentence of the paragraph justifying the use of LiftView vs
  InsecureLiftView might be more explicit if it said "If a user attempts
  to go to /ExpenseView/doEnumerate they’ll get a 404 because
  doEnumerate is not defined in the dispatch method." As I understand it,
  InsecureLiftView would also return a 404 for a request to /ExpenseView/
  privateMethod, since the method does not exist. Alternatively, if
  privateMethod were included in Listing 3.9 and did something
  destructive, it might highlight the insecurity of InsecureLiftView.
• The next paragraph (the last of 3.7) begins with "Another difference
  between custom dispatch and Views is that...". I don't know what
  custom dispatch is yet (as I've read that it's in section 7.2). At
  this point in my reading, this particular paragraph is a little
  confusing. Maybe it should be removed/reworked? Maybe it could give me
  a teaser of what custom dispatch is, to make me look forward to
  section 7.2?

Missing angle bracket

Loggin section uses deprecated method

The correct use of logging is on the wiki

Sample code of URL rewrite has compilation error.

In sec 3.7 code list 3.6, A Complex Rewrite Example, there is a val declaration,
val rewriter = {
case RewriteRequest(ParsePath(username :: Nil, _, _, _),
DeleteRequest,
httpreq)
if isMgmtSubnet(httpreq.getRemoteHost()) =>
RewriteResponse(deleteUser :: Nil, Map(username -> username))
}
The Scala compiler will compile the case statement to a Functionk or PartialFunction object, but if you don't specify the val type, there should be a compilation error. I think it should be,
val rewriter:PartialFunction[RewriteRequest,RewriteResponse] = {...}
My Scala version is 2.8.1.final.
This book is great, thanks for your work :-)
Thanks,

Cover FactoryMaker and Inject

A discussion on Mailer brought this up. It would be nice to discuss how FactoryMaker and StackableMaker work since it's pervasive in LiftRules.
