[Lift] Re: bind with outer element?

2009-08-12 Thread jon 

Hi,

I actually solved by wrapping the node i cared about in another node,
but tried the FuncBindParam and it does seem to only grab the child
nodes.

   t:name shorten=true /
   t:foo form=POST

   /t:foo
  /lift:Snippet

  And a snippet like:

  def doSnippet(x:NodeSeq):NodeSeq = {

 try:

 def myFunc(node: NodeSeq): NodeSeq = if ((node \ @shorten).isEmpty)
 longVersion else shortVersion

 bind(t, x, FuncBindParam(name, myFunc _))

 You get the complete t:name shorten=true/ passed to myFunc.

 Thanks,

  In the code above only the contents of the bound tags are available
  for doName and doForm, if I want to be able to read the attribute
  shorten in doName and have foo render with an enclosing form
  tag,  how do I create the bind params?

  I am doing an expensive batch operation upfront, so I want everything
  to be in the same snippet.

  Thanks,

BindHelpers.currentNode is a Box[NodeSeq] that gives you the node that  
bind is currently replacing.

Jon,

To read attributes, you do the following:

S.attr(shorten) // = Box[String]

Cheers, Tim

If I'm not mistaken, S.attr is an attribute on the snippet xml node; for the 
node currently being processed by bind you use BindHelpers.attr
