[Lift] Money and Mapper
Hi, I need to save some prices of products, while working in other languages I use some Decimal type so I don't have overflows and problems with IEEE floating point numbers. I see that Mapper has types for everything, from gender to postal codes... what about BigDecimal or Money?

[Lift] Re: Nested binding
That's what I need Heiko!!
But I've another problem, the following code:
def estante1 (xhtml : NodeSeq ) : NodeSeq = this.estante(xhtml,
Peluches, List(180L,34L,55L) )
def estante (xhtml: NodeSeq, nombre: String, listaProductos : List
[Long]) : NodeSeq = {
bind(estante, xhtml,
nombre -- nombre,
productos -- listaProductos.flatMap( id =
Producto.find(id) match {
case Full(producto) = bind(p,
chooseTemplate(producto,datos,xhtml),
nombre --
producto.nombre)
case _ = NodeSeq.Empty
}))
}
Applied to:
lift:estantes.estante1
div class=Estante
h3estante:nombre//h3
ul
estante:productos
producto:datos
p:nombre/
/producto:datos
/estante:productos
/ul
/div
/lift:estantes.estante1
Generates this xhtml:
div class=Estante
h3Peluches/h3
ul
List(
, Peluche de la E. Coli (Escherichi Coli),
,
, Peluche del Resfriado común (Rhinovirus),
,
, Peluche de la Sífilis (Treponema pallidum),
)
/ul
/div
Looks like a serialization of the NodeSeq, as if it doesn't concat the
nodes.
Cheers

Hi,
I want to render the content of some tables one after another:
table 1
data
table 2
data
table 3
data
I want to separate the XHTML from the code, so I'm trying to use
binding. My problem is that each table is rendered with the same XHTML
template, as every row.
If I use bind to bind the tables:
lift:mysnippet.tables
/lift:mysnippet.tables
What can I do to bind the rows inside this snippet so I can render
them? This is what I tried/want/expect:
lift:mysnippet.tables
table:name/
table:rows?
row:name??
/table:rows ?
/lift:mysnippet.tables
Best regards.

Because the compiler interpret your expression as you expect. Instead
of:
url_enlace - (/product/ + product.id.toString)
which is what you wanted, it got:
(url_enlace - /product/) + product.id.toString)
which it can do because it can take an arbitrary object:
(url_enlace - /product/): ABindParam
or (the other implicit -)
(url_enlace - /product/): Tuple2[String, String]
and convert them to strings. Of course, once it converts to string, it
won't fit in bind()'s argument list and so it gave you the could not
find overload error.
Honestly I'm a bit fuzzy on Scala's operator precedence behavior, I
think if I recall you can't set precedence, it comes pre-set on all
the standard operators like + / -, etc.

[Lift] Re: Snippet inside of a Snippet
SOLVED
I'd a value that was computed using the val id, I've turned it to
def and all works
now. As id can't be retrieved from URL parameters this val generated
an exception.
I think that the error message is a bit misleading :-/
Thanks!

because PaginaMarca can't

Well myClass2 is an invented name, I'll post the real code, but not

[Lift] How do you organize/use snippets?
Hi. I'd a hard time trying to solve a bug in a snippet. The bug appeared when I moved a method from a snippet to other so the code will be more organized. At first I tried to assign snippets to pages, so page Product.html will have a ProductPage snippet. In this snippet I'd values based in Product.html parameters. Then, as Lift implements a View-First design I supposed that I needed to collect snippets methods about something (product information for example) and put them in a ProductInfo snippet, but I found a bug: sometimes I put ProductInfo methods in pages that didn't provide the parameters that I get as val's. So my question is, how do you use/organize snippets? Do you get page parameters inside the def's (so they don't cause problems in some pages)? Do you follow a strict ViewFirst design?

[Lift] URL Rewrite and complex paths
Hi. I have the following problem (I'm porting a site from Python): I've an url path that follows the patern /something/int/text or the pattern /something/int/int/text. The type of the diferent parts of the url is important, in other platforms (Python/Ruby) it's possible to use regexp to match the urls... how is this done in Lift? This route /company/1/2 is valid and I need to extracts 2 parameters (id and page). This route /company/1/hi is valid and I need to extract just 1 parameter (id). By now my code is: case RewriteRequest(ParsePath(company :: id :: page :: text :: Nil, , true, _), GetRequest, _) = RewriteResponse(company :: Nil, Map(id - id, page - page)) case RewriteRequest(ParsePath(company :: id :: text :: Nil, , true, _), GetRequest, _) = RewriteResponse(company :: Nil, Map(id - id)) case RewriteRequest(ParsePath(company :: id :: Nil, , true, false), GetRequest, _) = RewriteResponse(company :: Nil, Map(id - id)) Cheers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Template tags and properties
Doesn't this put view code (XML/Xhtml) in controller code? I've read
many times
in Lift doc about not puting logic in view but the reverse can be
even
worst, doing impossible to have a separate design. You can't broke
logic but
design.

José,
You'll need to do this from yoursnippetcode - we dont have any view
logic in templates at all as that breaks lift view first model.
For example:
class YouSnippet {
def example: NodeSeq = aHi/a % href - /mypath/ +
someDynamicVar
}
In your template:
lift:your_snippet.example /
Does that make sense?
Cheers, Tim

Solved:
class MyObject {

}
In the view (as marius said):
img lift:snippet=MyObject:url_image/
