[Lift] Re: AJAX form with returned NodeSeq
Sorry my original question was unclear. I'm looking to submit data with the
form, and then get a response back from the server to act on.
The use case is that I have a list of things that I would like to add
elements to on the fly. The desired action is to have the list on the page,
with an add form below it. This form has two text fields, quantity and
item. When submit is clicked, I want to save the contents of those two
fields on the server, and update the displayed list with the new item added.
In other frameworks, the way that I've done this is to have the form
onsubmit contain code that made a jquery ajax call with the contents of the
form, and then would receive the full contents of the new list, which it
would drop into the DOM. Not sure how to rig that up in Lift, though.

can't seem to get the server to send a response to the client that can be

Is there a lifty way of doing this?

[Lift] Re: Code Review for Unique Key Constraints
Hey, I'm glad the code could make it in. One comment on your changes: It seems to me that using the pattern matching in ensureIndexes puts Lift in the position of maintaining support for various DBs, rather than letting the client code do it in a project by project basis (for instance, the FULLTEXT and SPACIAL index types that I mentioned, that are mysql specific.) Is there a reason that you preferred that over allowing client code to specify the index type? -Cale On Fri, Jul 10, 2009 at 5:32 PM, Derek Chen-Beckerdchenbec...@gmail.com wrote: I've pushed a smaller commit into the wip-dcb-unique-indices branch on GitHub that adds a UniqueIndex case class.

[Lift] Re: Building from source - error importing _root_.org.specs
I looked at, and redownloaded specs-1.5.0.jar earlier in the process, with no avail. However, last night I ran the tests as root, and after downloading the world, they succeeded.

[Lift] Re: Unique constraint
I looked into this a little bit. The relevant chunks of code seem to
be Schemifier.scala, lines 163 and 207, where
connection.driverType.pkDefinedByIndexColumn_? is checked before using
an ALTER TABLE to set a primary key, and Driver.scala, line 131, where
the H2Driver has pkDefinedByIndexColumn_? set to True with the comment
Whether the primary key has been defined by the index column. H2
creates primary key for a table, when AUTO_INCREMENT type is used.
So, it looks like lift is expecting H2 to use the autoincrement key as
the primary key automatically, but H2 isn't doing that, or isn't
reporting that it's doing that. However, I don't know enough about H2
to know which.
Hope that was helpful.

H2 has a great console servlet that you can use to connect to any jdbc

Assuming you already have H2 as a dependency, just add a mapping to the

web-app

descriptionThe Filter that intercepts lift calls/description

servlet-nameH2Console/servlet-name
url-pattern/console/*/url-pattern
/servlet-mapping
/web-app
Then you need to add a rule to LiftRules.liftRequest using the following
line in boot:
LiftRules.liftRequest.append({case r if (r.path.partPath match {case
console :: _ = true case _ = false}) = false})
That basically allows all requests that start with console to be ignored
by lift and passed thru to the servlet.
I am actually using PostgreSQL, but I prefer using this to pgAdmin or other
SQL tools.

[Lift] Re: Unique constraint
Currently, to create a 2 key index, you do something like: dbIndexes = Index(IndexedField(foo), IndexedField(bar)) :: Nil My intention is set it up so doing something like: dbIndexes = UniqueIndex(IndexedField(foo), IndexedField(bar)) :: Nil will create a unique index over the combination of both fields. -Cale On Fri, Jul 3, 2009 at 4:25 PM, Naftoli Gugenheimnaftoli...@gmail.com wrote: Okay.
