ParsePath

[Guillaume Massé]

Hi,

I'm really stuck with this rewrite:

http://localhost:8080/3457yerter

==>

http://localhost:8080/

Map( 'id' -> '3457yerter' )

What I got so far:

LiftRules.statelessRewrite.append {

case RewriteRequest( ParsePath( "index" :: id :: Nil, "", _, _ ), _, _ ) => 

RewriteResponse( "index", Map( "id" -> id ) )

}

[Naftoli Gugenheim]

So what's the problem?

Also what about Menu.param?

it gives me a 404

               LiftRules.statelessRewrite.append {

case RewriteRequest( ParsePath( "index" :: id :: Nil, "", _, _ ), _, _ ) => 

RewriteResponse( "index" :: Nil, Map( "id" -> id ) )

}

it try to match localhost:8080/index/3457yerter but I want it to match localhost:8080/3457yerter

               LiftRules.statelessRewrite.append {

case RewriteRequest( ParsePath( id :: Nil, "", _, _ ), _, _ ) => 

RewriteResponse( Nil, Map( "id" -> id ) )

}

wont work as well

Would you like to tell us what won't work in that case?

[Guillaume Massé]

also give me a 404

http://localhost:8080/aaaa

The Requested URL /aaaa was not found on this server

[Guillaume Massé]

and this give an infinite loop:

                 LiftRules.statelessRewrite.append {

case RewriteRequest( ParsePath( id :: Nil, "", _, _ ), _, _ ) => 

RewriteResponse( "index" :: Nil, Map( "id" -> id ) )

}

on any input

[Naftoli Gugenheim]

Try: case RewriteRequest( ParsePath( id :: Nil, "", _, _ ), _, _ )  if !id.isEmpty => 

[Franz Bettag]

So you want to catch everything starting at /?

Take a look at this: https://github.com/fbettag/println/blob/master/src/main/scala/bootstrap/liftweb/Boot.scala#L158-184

[Franz Bettag]

Or use naftoli's :) his is prolly easier to understand

[Guillaume Massé]

hey guys,

thanks for the help,

it's not an uriNotFound catch all, it's a link to a ressource. I'm building something similar to jsfiddle for scala ( see : https://groups.google.com/forum/?fromgroups#!topic/liftweb/C4GOz8bMe5g )

so it would be something like: 

sca.la/3529342 where 3529342 is the id for some scala ressource someone wrote.

case RewriteRequest( ParsePath( id :: Nil, "", _, _ ), _, _ ) if !id.isEmpty => 

     RewriteResponse( "index" :: Nil, Map( "id" -> id ) )

wont work as well, some infinite loop also.

Just use Menu.param.

[Guillaume Massé]

Thanks :-)

http://stable.simply.liftweb.net/#sub:Param-Example

[Guillaume Massé]

In that case Menu.Param wont work because you have to match the right template (index.html in my case).

ex:

Boot.scala

val sitemap = List( Menu( Kata.loc ) )

LiftRules.setSiteMap(SiteMap(sitemap:_*))

Kata.scala

case class KataRessource( id: String )

object Kata

{

val menu = Menu.param[KataRessource](

"Kata","Kata",

id => Full(KataRessource(id)),

kata => kata.id

) / "kata"     // << this will match kata.html

lazy val loc = menu.toLoc

val menu2 = Menu.param[KataRessource](

"Kata","Kata",

id => Full(KataRessource(id)),

kata => kata.id

) / ""     // << this will match ???

lazy val loc2 = menu2.toLoc

}

[Naftoli Gugenheim]

There are LocParams that let calculate the template. I'm not able to access the specifics at the moment but hopefully that will point you in the right direction.

[Guillaume Massé]

Hey,

I found the template resolving you were talking about:

object Kata

{

val menu = Menu.param[KataRessource](

"Kata", "Kata", 

      id => Full( KataRessource(id) ), 

      kata => kata.id ) / * >> 

Template( () =>

Templates( "kata" :: Nil ) openOr <b>template not found</b>

)

lazy val loc = menu.toLoc

}

notice the * catch all

notice that http://localhost:8080/ will have id "index"

Thanks again :-)

Guillaume

[Antonio Salazar Cardozo]

Yeah for what it's worth the RewriteRequest case match above needed to check whether id was == to "index" to avoid an infinite loop.

SiteMap is the way to go though :)

Thanks,

Antonio

Will that catchall still allow you to serve other objects at, say,
/index or /help/xyz or will all of them be served by your Menu.param? Or
would you need separate RewriteRules for those cases?

Thanks

The key thing about Menu.param is the function that takes the parameter and converts it into a typed value... in this case:

id => Full( KataRessource(id) 

If the function does not return a Full() Box, then the menu is not matched and other menus will be tested.

So, if the function is:

id => KataResource.find(id)

Will match existing KataResources but will not match the likes of "index" or "wombat".

Thanks,

David

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

That's a valuable piece of information, thanks! I assumed it would just
return 404 if there's no match.

Thanks,
Tobias

[Guillaume Massé]

Hum I was hoping for the other way around:

look the sitemap if we find something useful and then fallback on the catchall.

Thanks,

Guillaume
