Hello everyone,
I'm having some problems with making the MetaMegaProtoUser "edit"
method templateable (because I believe in the concept of separating
content and design) and am succeeding quite well, except for with one
little detail: I can't make my changes in the edit form persistent; it
seems that the "User" instance gets lost somewhere in the process and
that all the client-side changes therefore also get lost.
The code is at the end of the message. The edit method is called with
a template which also is at the very end of the message.
I would really appreciate if anyone with more Lift experience than me
could spot the mistake, because I simply cannot find it.
-------------------------------------------------------------------------------------------------
The "snippet" (inside a subclass of MetaMegaProtoUser):
/** Create an edit form with the specified template */
def edit(xhtml: NodeSeq) = {
val theUser: User = currentUser.open_! // we know we're logged in
def testEdit() {
theUser.validate match {
case Nil =>
theUser.save
S.notice("Profile updated") //The Lift Core has a spelling
mistake in its translation, so I don't use S.??
S.redirectTo(homePage)
case xs =>
S.error(xs)
S.mapSnippet(S.currentSnippet.open_!, innerEdit)
}
}
def innerEdit(t: NodeSeq) = bind("user", t,
"field" -> ((h: NodeSeq) => localForm
(h, theUser, true)),
"submit" -> SHtml.submit(S.??("edit"),
testEdit _))
innerEdit(xhtml)
}
/** Make a form with all the editable fields of an user, from a
template */
protected def localForm(xhtml: NodeSeq, user: User, ignorePassword:
Boolean): NodeSeq = {
signupFields
.map(fi => getSingleton.getActualBaseField(user, fi)) //get
actual fields
.filter(f => !ignorePassword || (f match { //remove the password
field
case f: MappedPassword[_] => false
case _ => true
}))
.flatMap(f =>
bind("field", xhtml,
"name" -> Text(f.displayName),
"form" -> f.toForm)
)
}
-------------------------------------------------------------------------------------------------
The template:
<lift:surround with="default" at="content">
<lift:User.edit form="POST">
<table>
<tbody>
<user:field>
<tr>
<td><field:name/></td>
<td><field:form/></td>
</tr>
</user:field>
</tbody>
<tfoot>
<tr>
<td> </td>
<td><user:submit/></td>
</tr>
</tfoot>
</table>
</lift:User.edit>
</lift:surround>
