Thanks, Derek. Actually, I don't use .html or even "add" (all my html
files are called index.html -- I use directories to sort them). This
error came when I was experimenting to see if that made a difference.
That said, I get the error all the time. I don't have val dispatch... in
my snippets. But that's because I copied the JPADemo over, and your
AuthorOps and BookOps don't have the val dispatch either. But the
JPADemo doesn't get this error.
Also, my edit functions don't work -- the forms are not populated
properly. I thought I had it working a minute ago, and now it isn't again.
I switched the snippets around a bit and dropped the bind (because I
wanted to color code alternate rows and wasn't sure how to do it
otherwise). Here is an example:
snippet/Category.scala:
import scala.xml.{NodeSeq,Text}
import net.liftweb.http.{RequestVar,S,SHtml}
import net.liftweb.util.Helpers
import S._
import Helpers._
import Model._
class CategoryOps {
val formatter = new java.text.SimpleDateFormat("dd MMM yyyy")
def getRowClass(r: Int) = {
if (r % 2 == 0) "even" else "odd"
}
def list: NodeSeq = {
<tr valign="top" align="left">
<th class="text">Name</th>
<th class="integer">Links</th>
<th class="blank"> </th>
<th class="blank"> </th>
</tr> ::
Model.createNamedQuery[Category]("findAllCategories").getResultList().toList.zipWithIndex.flatMap(c
=> <tr valign="top" class={getRowClass(c._2)}>
<td class="text">{c._1.name}</td>
<td class="integer">{SHtml.link("/links/search/", {() =>
WeblinkOps.resultVar(Model.createNamedQuery[Weblink](
"findWeblinksByCategory", "id" -> category.id).getResultList().toList)
}, Text(category.weblinks.size().toString))}</td>
<td class="edit">{SHtml.link("editor", () =>
categoryVar(category), Text("Edit"))}</td>
<td class="delete"> </td>
</tr>)
}
object categoryVar extends RequestVar(new Category())
def category = categoryVar.is
def editor (xhtml : NodeSeq) : NodeSeq = {
def addOrUpdate () = {
if (category.name.length == 0) {
error("emptyCategory", "The category's name cannot be blank")
} else {
Model.merge(category)
redirectTo("/admin/categories/")
}
}
val currentId = category.id
<form method="POST" action="">
<table class="editor" border="0" cellpadding="3" cellspacing="0">
<tr valign="top" align="left">
<th>Name</th>
<td>{SHtml.text(category.name, category.name = _)}</td>
</tr>
<tr valign="top" align="left">
<th>{SHtml.hidden({category.id = currentId})} </th>
<td>{SHtml.submit("Save", addOrUpdate)}</td>
</tr>
</table>
</form>
}
}
webapp/admin/categories/editor/index.html:
<lift:surround with="default" at="content">
<h2>Categories</h2>
<table class="list">
<lift:CategoryOps.list/>
</table>
</lift:surround>
And in Boot.scala:
Menu(Loc("categories", List("admin", "categories", "index"),
"Categories", LocGroup("admin")),
Menu(Loc("categories_add", List("admin", "categories", "editor",
"index"), "Add a New Category", Hidden))
),
ANY suggestions for how to do any of this better greatly appreciated. Do
I need to add the val dispatch... part? If so, why is this different
from the JPADemo?
Thanks!
Chas.
