Hi,
That's almost correct. I did following changes after looking into
JSON
content.
1. 'notice' and 'header' are JSON arrays just like 'data'.
Therefore:
case class Observation(notice: List[Notice], header: List[Header],
data: List[Data])
2. There's optional data in JSON (some datapoints are nulls and
Scala
Int or Double can't take null values). This can be fixed by
extracting
into Option.
3. The extracted Observation is in JSON field 'observations'.
Therefore:
(json \ observations).extract[Observation]
Your error stack trace suggests that you have an old version of
lift-
json. Please upgrade to M8, there was a critical bug in case class
extraction in older versions.
Full example which works for me:
implicit val formats = net.liftweb.json.DefaultFormats
case class Notice(copyright: String, copyright_url: String,
disclaimer_url: String)
case class Header(refresh_message: String, ID: String, main_ID:
String, name: String, state_time_zone: String, time_zone: String,
product_name: String, state: String)
case class Data(sort_order: Int, wmo: Int, history_product:

[Lift] Re: Problem with LiftFilter in 2.8.0
This is not the first time this has cropped up, you may have to sticky warning not to use 2.8 with Lift for the moment.

If you have any other version of Scala specified in your pom.xml file, it will not work. Do not try to mix different versions of Lift in the same web app. The class loader will not know which versions of the Lift library go with different Servlets.

[Lift] Re: Documentation Site
Well for the current information the places to go are http://scala-tools.org/mvnsites-snapshots/liftweb/index.html and http://wiki.github.com/dpp/liftweb if that will help you. On Dec 21, 7:47 pm, johncch john...@gmail.com wrote: Well, this is an apt discussion at this point in time I feel. One of the weakness of the Lift Project is really the sparse documentation, as well as the rapid cycle of development obsoleting virtually many of the slightly older code out there. I don't mind contributing my time improving the documentation. Perhaps one of the reasons why people don't contribute back is that the wiki is not very prominent, for one reason or another. It's just rarely referenced anywhere else most of the time. Would appreciate a more concentrated effort on this. I haven't actually seen the lift 1.1 scala docs. For example,http://www.scala-tools.org/mvnsites-snapshots/liftweb/lift-base/lift-... points to a blank page - that's for Lift common. I mostly rely on the IDE(idea) to open up declarations via maven.. not exactly the best method since the source code is more often than not not commented. The lift framework is pretty massive, I think that's the reason why it's difficult to write comprehensive documentation for it. I'm just wondering what is a good way to go about doing that? A list of how-tos plus in depth discussion about each part of the framework i.e. base, or common, or?

On Mon, Dec 21, 2009 at 3:34 AM, Indrajit Raychaudhuri indraj...@gmail.comwrote: Okay Folks, Lift 2.0 branch has shaped up enough for everybody to play with. Checkout the branch irc_wip_lift20 and get going! Just be aware that it's still undergoing updated and changes incrementally and there are few rough edges. Key changes: 1. The project tree has been restructured according to the proposal sent out earlier [1]. To summarize, we now have three top level projects (framework, archetypes and examples) each with independent build life-cycle. There are other additional infra projects that are less to do with the actual code. A quick summary of the top-level projects: 1. Framework: The whole of Lift Framework that matter most to most. The usual modules (viz., lift-base, lift-persistence and lift-modules) have got nested within. Therefore, from now on, building Lift framework would mean just that. Doing a git pull or git clone as usual, changing to framework directory and running mvn install. 2. Archetypes: The standard distributed archetypes. The archetypes help you get quick started with a Lift based project. If you are not into building maven archetypes, you can stay clear of this. But a quick probe is welcome. 3. Examples: All the Lift examples are grouped into this project. If you are generally interested in learning different techniques from examples you don't have to build the whole of Lift anymore. Well that was still the case earlier, but now it's even more obvious. And it's true the other way round too, if you have to build Lift framework from source, you don't have to build the examples along with it. Another point: the examples won't be deployed on scala-tools maven repo anymore. Those war files up there serve no good purpose. Everything now gets neatly tucked into their respective homes :) Additional points that you should be aware of: A. Availability on scala-tools repository: - Components of framework would be available - Components of archetypes would be available - Components of examples would *not* be available B. Availability on scala-tools Maven site: Site generated from framework would be the main content of scala-tools Maven site. Depending on how things go, we might even have a home of it's own athttp://dev.liftweb.net. (Separate proposal coming up) C. Lift Parent Project Model: The top level pom.xml has moved to it's own home at resources/project- model. This would stay as a 'flyweight' project (as in boxing, not GoF) on it's own that would strictly control the common behavior, plugin dependencies, versions etc. for all the top level projects (framework, archetypes, examples). This would be deployed on scala- tools repository. D. Lift Site Skin (WIP): I haven't started working on this yet. But the intent is to create a project site that is of some real value and serves as placeholder for mostly 'auto-generated' docs. See #B above. E. Still pending: a. Migration to Scala 2.8 branch. Intend to have stable master created first with everything working as usual without being caught into Scala release cycle. Hopefully, this branch and '280_port' would merge soon! b. Higher quality site generation (See #B above, proposal coming up) c. Site skin (See #D above) d. Hudson integration and better release management. So that certain steps in Committer release process [2] become automatic (waiting for merge to master and hudson maintenance) e. Having a nice README.md at the top level f. General spit and polish F: To be decided: a. Future of lift-core. (Separate mail coming) b. Relevance of OtherLicensedWorks.txt (repo distribution of javamail is now under CDDL and license automatically reflects in dependency page) c.

Hi David,
Thanks for presenting your latest work on Wizard last night at the Bay
Area Scala Enthusiasts meetup. I enjoyed hearing about Wizard and have
a few comments that I wanted to share with you and the rest of the
Lift community. I know Wizard is very new and I'm only going by what I
learned last night, so please bear with me if I misunderstood
anything!
As I understand it a Wizard instance is composed of screens
('questions'? I forget the exact terminology), each of which can have
multiple inputs, each input having a prompt ('Name', 'Your mother or
father's name', etc) and multiple validation rules. User input is
saved each time the user hits the Submit (or Next, in your example)
button. User state is stored from screen to screen and can be rolled
backwards but not forward. This is analogous to checking out an older
revision in a version control system, with each submitted screen being
a revision, but then loosing all revisions since the checkout
(rebasing the HEAD I believe it's called in Git).
What I expected, and what I think many other people would expect, is
that going back and forward among screens does not change the Wizard
state but simply changes what portion of the questions and responses
the user sees. In this case each screen is a simple, reduced view of
the current state, rather than a state in itself.
To use an analogy, think of a Wizard instance as an (annoying)
adventure game and each screen as a dungeon room. Let's say I fight my
way through several rooms full of grues, only to reach a locked door.
I'm told that the switch to unlock the door is 2 rooms back. I go back
(ie the previous screen method is fired twice) and I throw the switch.
Unfortunately, Wizard has also rolled back the dungeon state two
revisions and the intermediate room and room with the door now have
fearsome grues in them again! (In fact, I think Wizard could be used
quite easily for adventure games like that. Cool! I'm reminded of my
time making games in HyperCard. =)
To give another example, let's say I have a Wizard representing an e-
commerce site and have the following screens: shopping cart - name
and shipping address - credit card and billing address -
confirmation. If I get to the confirmation screen and see that I added
2 Widgets and only want to buy 1, I want to be able to go back to the
shopping cart screen to make my change without losing the addresses
and payment details I entered in the intermediate screens.
Am I describing Wizard correctly, and if so, why did you chose the
first method of operation over the second? Can the second mode be
added?
Not easily. Snapshotting at a point in time and rolling back to that point
is easy with immutability. Merging different branches of a given snapshot
is non-trivial and is not likely a feature that will make it into Wizard in
the near term. Put another way, 3 way merges on text is non-trivial. 3 way
merges on non-text is not a solved problem that I know of. Further, once
you merge text in Git, you have the compiler test to make sure that code
makes sense, but doing logic testing would be difficult during a merge
phase.
Thanks for all the great work and I'm really looking forward to using
Wizard!

this issue and has a workaround.
Who is deploying/configuring Lift's POM files? Are you using UTF-8 or
UTF-16 encoding? In either case, I would check the pom.xml for
lift-actors
in your local repo. Pull it up in a text editor that will show you all
characters and switch encodings.

Scala is not like, for example, BASIC, where you can look up FOR, IF/ THEN/ELSE. there's lots of individual and compound punctuation marks that are very difficult to search for online and in PDFs (try searching for !). This is where I am coming from, coding after a 16 or so year hiatus and my main language was basic so I guess I am one of the rare ones here who doesn't have the OOP/Java hang-ups, I just have a whole different set of hang-ups to deal with. I have been looking at Scala for some months and have to admit it is starting to sink in, of course having to learn everything else in order to learn it is making it take a bit longer. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

I would be far more interested in seeing something done for the benefit of the Lift Web Site. (Is it written with Lift?)

I think it is important for a web framework to use their own stuff, and it should be indicative of the cool things that it can do, stability, scale, and performance... (I am amazed that I have seen rather poor demonstrations of this, specifically by Adobe and JBoss -- but again, I'm not trying to be negative...) I see the Lift site integrating Google Analytics... Is that something that could be out of the box with Lift? That could be a selling point to people making external web sites. Another area that would be neat to develop is instrumentation. Sort of the JMX-Console equivalent for Lift. For scalability and sizing analysis, this would be really useful.

On Oct 15, 2:49 am, 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

[Lift] Re: lift nearly inaccessible for newby
Hello koveen, I'll tell you some of my experiences with Lift/Scala to give you some idea. I learned to code basic and some what they called then Machine Language on a Commodore Vic 20 and a 64 oh so long ago, I learned a bit of C then gave it up. I learned a bit of PHP since then but that's it. I'm learning Scala/Lift because I want to, not for a particular site I want to make. If you are determined to learn it there are some things you need to understand then. OOP is the very first, if you do not have an understanding of Object Orientated Programming then you'll not see why the code is written the way it is. I would suggest learning what Functional Programming is as well as you will be dealing with it to a lesser degree. You need to learn the basics of Java (what classes are, whats an interface, etc.) as they will be referenced because it is assumed you already know these. You have something most of the others here do not have, pre-conceived notions, the same Java programmers that do know the basics are also constrained a bit by that knowledge. Scala has differences from Java that they have to overcome to learn the language. What I suggest is if you have a site you have to make soon do it in something else and study Scala more, if not then readas many of the Scala books you can find (Davids is a great book and the lift book is a great basic book) Martin's book I'd suggest getting as he has definitions of Java terms and explains some of the Java basics. Anyway, good luck. On Oct 7, 4:40 am, koveen liep...@xs4all.nl wrote: David, no need to appologise!

Personally, I don't think Lift is materially more complex than Rails, although Rails' documentation and examples are worlds better than Lift's (this is not a put-down of the excellent work done by the whole community and Marius, Derek, and Tyler specifically, but a simple indication of being 4-5 years behind Rails in terms of adoption.)

For the large part, I agree, the level of questions even I know is geingt a bit too much, and the amount of patience you all use answering them even though you know you just answered that a week ago is commendable. That said you commiters don't have time to waste answering those questions, that's what we are for :) and it is happening. There are people here that are not commiters that are answering those questions and others. I've been a lurker here for over a year and even I am answering an occasional answer. Maybe writing what you understand into the Wiki should be promoted more, mention it on the title pages of lift, maybe even bring in a commiter or two in with the express idea they are working on the Docs/ wiki. Bring in some support crew so the commiters only have to worry about committing :) Personal Opinion: To be fair to Lift commit team, there is quite a bit of example code online for people to check out, but I'm not convinced they are actually looking at it. Given the number of questions that come in that are easily solved with a Google Search, I don't know how pumping out more and more docs and examples will help, as it seems largely ignored. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: TableEditor article
Ah, I looked for tableeditor in the scaladocs but was unable to find
it.
On Aug 22, 6:05 am, Naftoli Gugenheim naftoli...@gmail.com wrote:
I should have thought of that problem.
I could make TableEditor more flexible when I have time, but the truth is
that I don't know if it's worth it. The whole thing is less than 80 LOC with
scaladocs (not counting the utilities it uses which you can also use). The
real logic that provides its semantics is ItemsList, which includes
sortability, and is public. So it's probably not worth it to not write your
own snippet! The value of TableEditor is that it's automatic--3 lines in the
view and two in Boot, (actually that could surely be lessened when I have a
chance) and it works on any table. Once your customizing it it might not be
worth it. It basically does old fashioned binds, backed by an ItemsList
(better name anyone?). Also it uses eachField from mapper.view.Util, but in
your case you know which fields you have.
What do you think?

Naftoli,
I must be doing something wrong. I tried the following, as you
suggested,
inserting the extra xml after the item:fields tag, but
ManagerUsers.list does its
own iteration through the table items and I get duplicate columns.
ManageUsers.list just does a bind to the myuser:roles tag.
table:items
tr
item:fields fields=firstname lastname email
td style=vertical-align: topfield:form //td
/item:fields
lift:ManageUsers.list
td style=vertical-align: topmyuser:roles //td
/lift:ManageUsers.list
td style=vertical-align: topitem:removeBtn //td
/tr
/table:items
Then, I have the added problem of saving changes to the item, since
roles is not
a field recognized by ItemsList.save.
Any suggestions??

Naftoli,
I like the checkboxes style for a small selection (say 10 or less),
and perhaps a multi-selectbox if the choices are more numerous.
Another approach is to use two list boxes, one for the choices and
another for the selections, with maybe a drag-and-drop capability or
some add/remove buttons in between. I guess there is no good default
solution.
One enhancement to your tableeditor would be a tableviewer option,
using a field:toXml instead of a field:form tag.
Thanks for your help.

The name is really a misnomer. It's not a MappedField. So it's missing
the opposite half: it _is_ the validSelectValues but it doesn't have the
toForm method of MappedField's to make use of its values.
I'm not sure how a hypothetical toForm would work for a many-to-many
field. Actually it depends on the circumstances. One option is how MS
Access works---every time you select a value you get a new blank row. This
is good where you can have many or duplicate children, but is more complex
to implement. Similarly you can have a list of current children and a
dropdown to add. Another option (where duplicates are not allowed) is a
set
of checkboxes.

Sorry for the addendum, but ideally, it would be nice to

Oh, I think I know what the problem is. I think I should classify it as a bug.
Since you're adding a Role that isn't saved yet, and ManyToMany tracks the
children via the join table, it can't access the child. As a workaround save
the Role before adding it, although the need to do so is against the idea of
ManyToMany and OneToMany. I will see what I can do, G-d willing.

By the way, as per my correction, you can implement list the regular way
without ModelView, and just use ModelSnippet's load function in your edit

Naftoli,
I fixed my code per your comments and now I can edit and remove users
from a list, as long as I populate the list with
ModelView instances, as you said. As for the docs, this step was not
clear to me at all. I just assumed that the list was
just populated with User entities and the view in the ModelSnippet was
instantiated with the selected User on each request.
It sounds like your plate is pretty full, so I won't expect much, but
sometime soon, could you provide an example, or improved
docs, for using TableEditor and its related ItemsList trait.
Thanks for all.

To answer your immediate question, the listing should not refer to the
snippet's view but new ModelView instances for each entity. Then
editAction is shorthand for the snippet's link method with a callback to
call load on the ModelView. To set the snippet's view's entity, either
call load on the snippet with the other ModelView, or call load on the
other ModelView (or just set its entity directly).
As far as documentation, please tell me what scaladocs need what
clarification. Thanks.
