[Lift] Re: buttons and textbox
Lifted,
When i look at the button behavior using firebug, this is the following
error i see.
F891109765602PT1 is not defined
onclick(click clientX=950, clientY=152)1tbfBLwe...6bg%3D%3D (line 2)
(F891109765602PT1, lift_ajaxHand...whatField).attr(value), null, null));
It would appear that however the
ajaxCall(JsRaw($('#whatField').attr('value'))
is working it is setting up a handle that is stale by the time the behavior
is actually invoked. This is behind-the-scenes stuff for a programmer like
me. It's part of what lift is s'posed to provide. Moreover, i get no help
from the compiler. The code i have written is well-typed. Any help would be
greatly appreciated.
Best wishes,

[Lift] Re: buttons and textbox
First of all instead of:
(onclick - ajaxCall(JsRaw($('#whatField').attr('value')), s =
updateWhat(s))._2)
I would use:
(onclick - ajaxCall(ValById(whatField), s = updateWhat(s))._2)
That should work I think in your case you are setting the value
attribute of the text field to lambda.x.x and $('#whatField').attr
('value') is just returning the 'value' attribute of the whatField
node. This returns the value set statically which is different from
document.getElementById(whatField).value. I know it's a bit odd ...

Marius,
Thanks! That works much better. One final question, if i wanted to have the
CR/LF event on the textbox have the same behavior as the button, what would
be the simplest approach? Currently, i have
{ text(evalStr(), (updateWhat _)) % (size - 60) % (id - whatField)
}
which always reverts back to the initla value of the textbox.

The Getting Started document got me hooked on Lift. :-)
I guess I'll report my struggles from there. I don't know if what
I did
is typical.
After actually running the two examples from the Getting Started
docs,
I looked and found some other examples, did some looking around in the
mailing list archives and started reading the Exploring Lift book.
As a starting application of lift, I want to write a simple purchase
order tracking webapp. It was easy enough to figure out how to
hook up
PostgreSQL instead of Derby. I started experimenting with the CRUDify
trait and got several tables working, but then I got stuck trying to
make a more cohesive app. What I could not figure out was how to use
CRUDify's functionality without having to put all the options in the
SiteMap. So I spent a lot of time trying to figure out the SiteMap
class. I have since come to the realization that I probably shouldn't
be using CRUDify, as non of the examples actually use it. I have also
realized that I should be putting rules in LiftRules.rewrite.
I don't think so. I think that you should be using SiteMap. SiteMap
is the best tool for defining site navigation and access control rules
around.
CRUDify and ProtoUser are like scaffolding... they get you some pieces
really quickly, but you'll ultimately need to replace them. You
should never have to replace SiteMap.
So... what's the specific challenge you're running into with SiteMap?
The first challenge I had was trying to figure out how to keep the
functionality of CRUDify, but not the menu items. The docs state that
you can override defs. ie:
*createMenuLoc* |def createMenuLoc|
The menu item for listing items (make this Empty to disable)
Box javascript:void[Menu javascript:void]
But I don't want to disable it, just hide it from the menu.
Then, failing that, I wanted to put the menu items in a sub-menu in the
SiteMap. I wasn't able to accomplish this while keeping the CRUDify
functionality functioning. (The submenu seems to always to add a level
to URI but the CRUDify trait doesn't know about that? I could be
grossly wrong, of course!)
Ultimately, in the app I'm trying to build, CRUDify would only be useful
for the main record type. Most other records have a 1-n relationship
with the main record. It is unclear to me how to use CRUDify in this
situation. (I can use CRUDify to add a PO, but how do I use CRUDify to
add SKUs to a specific PO?)
So, looking at the pocketchange app which has this kind of record
relationship as well, I figured that CRUDify was not the right
solution. (I hope I'm wrong, because I like what CRUDify provides!)
So, my point, I guess, is that it was never clear to me what request
rewriting was all about. I didn't understand the explanations and
basically just skipped it and tried to do everything with SiteMap.
What I have taken away from this: Request Rewriting sounds very
advanced and made me think of sendmail rewriting rules! (Yuck!)
Maybe it would be good to have some blurbs on Lift for JEE
developers. What is the equivalent of mapping a URL to a servlet and
how do you deal with the URL pattern matching. (I want to map
/foo/*
to a some soft of action)
So that would then be a nice lead-in to coverage of
net.liftweb.http.S,
right?
Anyway, back to API docs, it never occurred to be to look at the docs
for net.liftweb.http.LiftRules! There are actually lots of comments
there. The rewrite is kinda hidden there, so it probably should be
called out in the class docs. Then for the actual rewrite docs, it
would be nice to give some examples of what should go in there or
provide a link to external docs showing the same.
How have other people tackled the learning curve of lift?

[Lift] Sample applications are somewhat slow - is Lift slow ?
Hi, I'm very new to lift and scala.

[Lift] User model
Hi all, I've just started playing with Lift so forgive me if this question seems a bit naive - that would be because I am a newbie :) I am trying to build a webapp with user authentication. However, I don't want to use ProtoUser because I want to key it by the userid - which is a unique String not a Long. Since the doco is a bit sparse I am at a bit of a loss at how to get user authentication done without using ProtoUser. Any pointers would be appreciated.

[Lift] Re: objet vs class for snippets
Tim, Dispatching snippets by registering with LiftRules is much faster than the by convention mechanism of looking up the class name. It's also type-safe (an issue that Greg Meredith ran into last week.) So, it's a few more lines of code, but better. Unless you've got a Stateful Snippet, you shouldn't be keeping any state information in the snippet instance and thus object is better than class.

Since the doco is a bit sparse I am at a bit of a loss at how to get user authentication done without using ProtoUser. Any pointers would be appreciated. There's no such thing as user authentication built into Lift. Lift has no concept of a User. All code for authentication is built on top of simple Lift constructs. Lift has a concept called a SessionVar which allows you to put a type-safe value into a place that's session-specific. In MegaProtoUser: private object curUserId extends SessionVar[Box[String]](Empty) def currentUserId: Box[String] = curUserId.is private object curUser extends RequestVar[Box[ModelType]](currentUserId.flatMap(id = getSingleton.find(id))) def currentUser: Box[ModelType] = curUser.is So, the curUserId SessionVar stores the currently logged in User's id (as a String). The curUser RequestVar is the current User object, but calculated on a request-by-request basis. This is all you need for your own authentication mechanism.

I don't know if what I did is typical. After actually running the two examples from the Getting Started docs, I looked and found some other examples, did some looking around in the mailing list archives and started reading the Exploring Lift book. As a starting application of lift, I want to write a simple purchase order tracking webapp. It was easy enough to figure out how to hook up PostgreSQL instead of Derby. I started experimenting with the CRUDify trait and got several tables working, but then I got stuck trying to make a more cohesive app. What I could not figure out was how to use CRUDify's functionality without having to put all the options in the SiteMap. So I spent a lot of time trying to figure out the SiteMap class. I have since come to the realization that I probably shouldn't be using CRUDify, as non of the examples actually use it. I have also realized that I should be putting rules in LiftRules.rewrite. I don't think so. I think that you should be using SiteMap. SiteMap is the best tool for defining site navigation and access control rules around. CRUDify and ProtoUser are like scaffolding... they get you some pieces really quickly, but you'll ultimately need to replace them. You should never have to replace SiteMap. So... what's the specific challenge you're running into with SiteMap? The first challenge I had was trying to figure out how to keep the functionality of CRUDify, but not the menu items. The docs state that you can override defs. ie: *createMenuLoc* |def createMenuLoc| The menu item for listing items (make this Empty to disable) Box javascript:void[Menu javascript:void] But I don't want to disable it, just hide it from the menu. Then, failing that, I wanted to put the menu items in a sub-menu in the SiteMap. I wasn't able to accomplish this while keeping the CRUDify functionality functioning. (The submenu seems to always to add a level to URI but the CRUDify trait doesn't know about that? I could be grossly wrong, of course!) Super-menus and sub-menus share no URL information with each other. A super-menu could be at /foo/bar/baz/super and sub-menus could be at /dog and /cat Ultimately, in the app I'm trying to build, CRUDify would only be useful for the main record type. Most other records have a 1-n relationship with the main record. It is unclear to me how to use CRUDify in this situation. (I can use CRUDify to add a PO, but how do I use CRUDify to add SKUs to a specific PO?) CRUDify is for building simple CRUD apps. It's not meant for complex relationships. Until someone comes up with something better, you'll have to hand-code the relationships and the screens for the relationships. So, looking at the pocketchange app which has this kind of record relationship as well, I figured that CRUDify was not the right solution. (I hope I'm wrong, because I like what CRUDify provides!) Sorry. David So, my point, I guess, is that it was never clear to me what request rewriting was all about. I didn't understand the explanations and basically just skipped it and tried to do everything with SiteMap. What I have taken away from this: Request Rewriting sounds very advanced and made me think of sendmail rewriting rules! (Yuck!) Maybe it would be good to have some blurbs on Lift for JEE developers. What is the equivalent of mapping a URL to a servlet and how do you deal with the URL pattern matching. (I want to map /foo/* to a some soft of action) So that would then be a nice lead-in to coverage of net.liftweb.http.S, right? Anyway, back to API docs, it never occurred to be to look at the docs for net.liftweb.http.LiftRules! There are actually lots of comments there. The rewrite is kinda hidden there, so it probably should be called out in the class docs. Then for the actual rewrite docs, it would be nice to give some examples of what should go in there or provide a link to external docs showing the same. How have other people tackled the learning curve of lift? --Andrew Derek Chen-Becker wrote: In terms of the API docs part of it would just be expanding on the current scaladoc to provider better explanation.

My personal view is that a worked example of a fully featured eCommerce type site would be most useful.

That would be a useful foundation for the rest of Lift's features (add-ons such as online chat style help). I'm looking at technologies for rewriting a web site with a lot of dynamic content, currently written entirely in Java 1.4 and JSPs. Scala and Lift look promising, but the lack of documentation and non trivial worked examples mean that despite Lift's 1.0 status, I don't feel I could use it in its current form.

[Lift] Re: How to handle refresh with S.redirectTo with state?
I believe I am doing #1 now with no luck. Let me know if this is
correct:
class Cars {
// ...
object locationQuery extends RequestVar[Box[LocationQuery]](Empty)
def search(xhtml: NodeSeq): NodeSeq = {
def processSearch() = {
// ...
val lq = new LocationQuery(validPickupDate.open_!,
validDropoffDate.open_!, city, city)
S.redirectTo(/select, () = { locationQuery(Full(lq));
requestReference(Full(requestRef)) })
}
// binds are here
}
def selectedLocation(xhtml: NodeSeq): NodeSeq = {
if (locationQuery.isDefined) {
val selectedCity = locationQuery.open_!.pickupLocation
Text(selectedCity.name + , + selectedCity.region)
} else {
Text()
}
}
// ...
}
Thanks,
Bryan

Well instead of open_1 use openOr so that you wont get exceptions when
the Box is Empty. Also if you want when you to the redirect you could
propagate those RequestsVars as well so that your browser re-send
them. Now sure if this is what you'd want but should help avoiding
Empty request vars. But what I'd do is:
1. Since you are doing redirect with state in the function passed to
S.redirectTo you can set relevant values to your RequestVar's .. hence
when your page is rendered your request vars have the old values
potentially.
2. Use a StatefulSnippet and call redirectTo from the StatefulSnippet
not S. Hence you can save state inside your snippet and when redirect
happens, the same snippet instance would be used.
Br's,

I have a snippet that calls S.redirectTo with state. In this same
snippet class I have a few functions to show the values of the
processed RequestVar's. This works fine until I refresh the page,
because in these functions I call .open_! on some now Empty
RequestVar's. It is simple enough to show Text() when the box is
not Full, but now I have a problem with the page not showing useful
data.
What are some suggestions for handling this? Should I just add code
to each of my many snippet functions to redirect to / when the
RequestVar's are empty?

[Lift] Re: Lift documentation -- Attention newcomers (and everyone else)!
Richard, its a shame you feel like that. Your comments about examples are noted, however you must bear in mind that both scala and lift are young (relatively speaking) and a lot of the applications that are out there, are behind corporate firewalls (including mine) - so don't be fooled into thinking lift is not production ready or feeling that its not usable, were just a little lacking right now in the documentation, but 100% *not* lacking in the implementation (lift rocks out) Stuff like ecommerce will grow up around lift as more people adopt it - the same was true for rails... When I started using rails there were naff all examples out there, so we just had to get on and make some - years later and the story is very different. The same will no doubt happen for Lift... Its just a waiting game - its people like your good self who can help with this: invest a bit of time and write some examples for the benefit and learning of all. Let me just say this, as its probably the best advice I can give: If you do decide to go with lift, you will not regret it. The rest of the lift team are some of the best developers and architects I have ever had the fortune to work with - and they all give up large amounts of their time to participate and help the community... To that end the lift community is one of the most intelligent and welcoming out there. Over the past two years this has pretty much been my experience and im sure others will concur. Good luck with your project and I hope you might reconsider your viewpoint on lift.

[Lift] How would I call a template from another template?
Very simple idea - I have a tags template that I put in the templates- hidden directory, it creates a list of tags. In one of my public templates I want to be able to call that template to display the tags (I'm sure it has been done before and I cannot find in either book where this is covered).

[Lift] Re: How to handle refresh with S.redirectTo with state?
Would that mean that the state of the RequestVar could accidentally be

Well instead of open_1 use openOr so that you wont get exceptions when

propagate those RequestsVars as well so that your browser re-send
them. Now sure if this is what you'd want but should help avoiding
Empty request vars. But what I'd do is:
1. Since you are doing redirect with state in the function passed to
S.redirectTo you can set relevant values to your RequestVar's .. hence
when your page is rendered your request vars have the old values
potentially.
2. Use a StatefulSnippet and call redirectTo from the StatefulSnippet
not S. Hence you can save state inside your snippet and when redirect
happens, the same snippet instance would be used.

not Full, but now I have a problem with the page not showing useful

What are some suggestions for handling this? Should I just add code
to each of my many snippet functions to redirect to / when the
RequestVar's are empty?

[Lift] Re: Cannot access html files other than index.html in GAE using lift
I just broke my teeth on this problem also (and 2 days wasted later I discover this thread). I would say Doh!, but this is hardly a Doh type of thing. Security is important, but also as a new framework, you want rapid uptake by people who won't read 5 chapters of a book before trying something out. Many of us (most of us?) read the minimum amount before jumping in and trying something. Here is my proposed user story: As a new Lift user, I can copy-paste lift-archetype-blank files into my existing web site and gradually add Lift functionality while unmodified static and JSP content continues to work. Perhaps this could be done by having a simple method on SiteMap to disable access control. (And then use it in lift-archetype-blank, with comments of course.) Many people will likely do what I did, trying to figure out how to turn on logging levels, etc. because the behavior they expect is not what Lift delivers, and then they blame themselves for doing something obviously stupid. (But failing to read 5 chapters is not obviously stupid.)

BTW, to the authors of that book: I spent a lot of time trying to figure out this exact same issue. Could you make this more prominent? Some examples of using multiple pages would be helpful. Since the SiteMap is so important, I think it would be good to add more coverage of it in chapter 3. Andrew, Thanks for your comments. There's a tension in Lift between quick simple and maintainable secure. SiteMap is a little heavier weight than simple routing tables (or doing things by default). On the other hand, SiteMap gives you security, menu generation, bread crumbs, and much, much more. Perhaps I'll add something to the 404 when running in development mode (or bespin mode).

Hello List! I might as well share my thoughts about docs. I think as with Scala and Lift you should try to beat the best that is out there. And from all the user made language/API/framework wikis I have seen the one from a now pretty unpopular game is by far the best: http://wiki.secondlife.com/wiki/LSL_Portal It is one page and you have _all_ the infos you need. Everything. Even in different languages. And _EVERY_ function as good exampleS to go along with it. That wiki is way better than any other IMNSHO. _Easily_ beats the ROR wiki. You just go to that page and boom you get everything there is to know PERIOD No unanswered questions. I hope the current API docs will be integrated into the wiki. Because those sure are not newbie friendly and lack explaination and examples. With similar docs lift will be the most popular web framework in no time, but I think with mandatory registration it will not happen. That does not scale and discourages people.

James, This looks more like about $20, but I'm not complaining. Your thoughts mirror mine in many ways. #4 is a very good idea. Even just a list of what is needed. Folks could add to a documentation wishlist, and then anyone who thought he or she could tackle an item could just do it. I'm glad that people are finally responding to this thread. I was beginning to think that I was on my own... Chas. James Matlik wrote: Hello Charles, This is good news. I'm sorry I didn't see your initial email going out, but I would guess it is better late than never. I think the first thing that needs to be done is to clearly define what is to be documented in the wiki and where. Here is my 2 cents: 1. There should be a page linked to the wiki's main page providing marketing style information. This could be a kind of About Lift page on steroids. What makes Lift novel? What features does it provide that simplify the state of the art in web development? How easily can the technology be integrated with legacy deployments? What design goals does Lift strive for and why? Does Lift have a viable future? What is Lift's stance on KIR support? Once an official release is made public, will bug fixes be applied to that version going forward and for how long? How stable is the API? 2. A brief description of the Lift culture could be beneficial; a kind of welcome to the party, this is how we roll for the uninitiated (I'm still figuring it out). 3. Make a clearly defined section for people developing applications with Lift. Give a 100ft view of the code/compile/deploy/test development cycle, then delve into the tools that make this cycle simpler. Provide the basics on Maven, what it is, what it does for Lift, and the commands of interest for Lift development. Describe how Maven is not required for the Maven adverse, and provide instructions on how to proceed without Maven (maybe an opportunity for sbaz?). Up-to-date HowTo documents on standing up different editors (Nebeans, Eclipse, Idea, etc.) are important. How should Lift be deployed? What are the required dependencies? Is it reasonable to simply use Maven's jetty:run target for a production deployment? What are the common configuration settings for various servlet containers for development vs. production deployments. What architectures should be used for scaling out deployments for redundancy and performance (serialization, Terracotta, load balancing, etc.)? Development, deployment and KIR overview for those familiar with Rails but not with Java. 4. A documentation TODO list for people to contribute. 5. Are there any best practices? Some good topics could be I18N, how to avoid introducing security vulnerabilities like cross site scripting or SQL injection attacks, how best to leverage templates for CMS-like systems with very large numbers of unique pages vs. applications with a relatively short list of screens, security and performance tuning. 6. There needs to be a very clear division between documentation for public reference and works in progress/new feature collaboration that would only confuse people. 7. There is a lot of good example code in the lift demo app. It might be nice to provide some supplemental annotated documentation in the wiki (a lot of people don't turn to the code by default). This could be a kind of recipes for Lift section that could contain all kinds of examples including those in the demo app. As people contribute creative solutions or solutions to common problems, they could eventually be pulled into the demo app. I'm sure some of this already exists on the wiki, but it would nice if the navigation made it easier to find. As for registering with the wiki, could OpenID be supported for the wiki account? I'm seriously tired of creating new accounts all the time with the same unchanging handful of passwords that I regularly have to cycle through when accessing my account. I'd like to see OpenID implemented everywhere. On Tue, Apr 21, 2009 at 3:38 PM, Charles F.
