[Lift] Re: Modify CRUDify XHTML
Thanks, David. Unfortunately I'm having a hard time figuring out how
to get the foundParam.
Using your code, I have:
val loc = for {req - S.request; loc - req.location} yield loc
val l = loc openOr Couldn't open
println(loc)
println(l)
The first println give me:
Full(Loc(View List(nodes), function, LinkText(function), List()))
While the second shows that I am opening the Box:
Loc(View List(nodes), function, LinkText(function), List())
If I try to access my Loc object, I get compilation errors. For
example, val p = l.foundParam leads to the error value foundParam
is not a member of java.lang.Object. The toString method works, while
the title parameter gives me the same error. I believe I am using the
latest Lift code (I ran mvn -U jetty:run) and feel I must be missing
something very simple here.
Any advice is much appreciated!

So the simplest thing is to override _viewTemplate with something similar

[Lift] Re: Modify CRUDify XHTML
Well if the box is empty l will be a String so of course you can't access
foundParam.

Instead of yielding loc which is taking it out of the box and putting it back
in, access foundParam inside the for loop.

[Lift] Re: Modify CRUDify XHTML
Thanks Naftoli and David, I'm starting to understand what I need to
do. However, the solution has revealed a gap in my beginner's
knowledge of Scala: why was my code printing out the Loc instead of
Couldn't open?
Second, even with foundParam.is within the for comprehension, I still
need to get the the value out of the comprehension – the rest of my
snippet is based upon it. So, I still need to openOr the Box, no? If
so, how? Is there a more functional and Scalarific way to do this?

I don't think you have to pull the value out of the for comprehension... do
all the work inside the for comprehension.
When you're doing your design, think about transformation. You'll
transforming input to output. In this particular instance, what kind of
transformation are you performing?

[Lift] Re: Modify CRUDify XHTML
A Box is a container that holds 0 or 1 elements(s). openOr means if the Box is
Full return the element; otherwise return the parameter--my default value.
One alternative approach would be to specify a default Loc.

Hi all,

If you look at the source to CRUDify, you'll see
def viewTemplate(): NodeSeq = pageWrapper(_viewTemplate)
where
def pageWrapper(body: NodeSeq): NodeSeq =
lift:surround with=default at=content
{
body
}
/lift:surround
def _viewTemplate =

table id={viewId} class={viewClass}
crud:row
tr
tdcrud:name//td

/tr
/crud:row
/table
/lift:crud.view
So the simplest thing is to override _viewTemplate with something
similar
to the above. This should be done on the companion objects where
CRUDify
is mixed in

To the extent that you can call it transformation, I'm trying to

Okay... makes sense.
Yes, the reference contained a Loc, but the compiler could not verify that
it contained a Loc. At compile time, the compiler knows the common
superclass between Loc[_] and String is Object. Thus the type of l in your
code was Object and Object doesn't have the foundParam method.

Please do not use open_! The ! is there for a reason... it means use this
at your peril.
Either use openOr and have the expression on the right side of the openOr
return the same type as the expression on the left (Loc[Node]) or
alternatively, do pattern matching:
thing match {
case Full(x) = // do something
case _ = // some fallback
}
Using open_! is super duper dangerous and generally very, very bad practice.

If you look at the default _viewTemplate:
1.def _viewTemplate =
2.lift:crud.view
3. table id={viewId} class={viewClass}
4. crud:row
5. tr
6. tdcrud:name//td
7. tdcrud:value//td
8. /tr
9. /crud:row
10. /table
11./lift:crud.view
You'll see that it uses the binding tags of lift:crud.view /, crud:row
/, and crud:name /. Those are used to fill in the values for a given
instance. I would base whatever new template you want off of that.

So the simplest thing is to override _viewTemplate with something similar
to the above. This should be done on the companion objects where CRUDify
is mixed in

[Lift] Re: Modify CRUDify XHTML
How would you customize the edit view, say to allow editing all child
entities on the same screen?

Hi all,
I'm using CRUDify on one of my models and I'd like to display some
additional data on the view template. I believe that I need to
override one of the model definitions with some sort of reference to
my own XHTML file. Which one? _viewTemplate? Or perhaps the
viewTemplate method?
If you look at the source to CRUDify, you'll see
def viewTemplate(): NodeSeq = pageWrapper(_viewTemplate)
where
def pageWrapper(body: NodeSeq): NodeSeq =
lift:surround with=default at=content
{
body
}
/lift:surround
def _viewTemplate =
lift:crud.view
table id={viewId} class={viewClass}
crud:row
tr
tdcrud:name//td
tdcrud:value//td
/tr
/crud:row
/table
