how to Record Referenced Objects

[Sanx]

Greetings to all

I am using the following example from the wiki:

Record Referenced Objects

https://www.assembla.com/spaces/liftweb/wiki/Mongo_Record_Referenced_Objects

but with the following changes:


class Posts private() extends MongoRecord[Posts] with
ObjectIdPk[Posts] {
def meta = MainDoc

object name extends StringField(this, 12)
object userId extends ObjectIdRefField(this, User) {
override def options = User.findAll.map(user => (Full(user.id.is),
user.nickname.is))
}
}
object Posts extends Posts with MongoMetaRecord[Posts]



class User private() extends MongoRecord[User] with ObjectIdPk[User] {
def meta = RefDoc

object nickname extends StringField(this, 12)
}
object User extends User with MongoMetaRecord[User]


and I want to make a query to get the following:

<span id="rows">
<p id="name">My post</p>
<p id="nickname">My nickname</p>
</span>

and the query that I'm trying to do is this:

val post = Posts.findAll()

"#rows" #> post.map { p =>
"#name" #> p.name &
"#username" #> p.userId.obj.user.nickname.is)
}

I know something is wrong with the following line:

"#username" #> p.userId.obj.user.nickname.is)

My question is this:

anyone can help me and please tell me what I'm missing or what I'm
doing wrong

I have no experience with Mondodb and am trying to understand how to
use the references

Thanks for your attention

Hi Sanx,

Your problem might be that p.userId.obj returns a Box[User]. Try this:

"#username" #> p.userId.obj.map(_.nickname.is)
