斯卡拉列表validSelectValues沒有更新

Question

這是我在一類建築代碼：

object province extends MappedLongForeignKey(this, Province) { 
    override def dbColumnName = "province_id" 

    def selectValues: Box[List[(String, String)]] = 
     Full((("0", "")) +: Province.findAll(OrderBy(Province.name, Ascending)). 
       map(p => (p.id.is.toString, p.name.is))) 

    override def _toForm: Box[Elem] = Full(selectValues.flatMap{ 
     case Nil => Empty 
     case xs => Full(SHtml.ajaxSelect(xs, Full(this.is.toString), v => { 
      this.set(v.toLong) 
      JsCmds.ReplaceOptions("council_select", 
        councilsList(v).map(c => (c.id.is.toString, c.name.is)), None) 
     })) 
    }.openOr(<span>{"sin provincias"}</span>)) 

    private def councilsList(p: String) = p match { 
     case id if id != "" => 
      Council.findAll(By(Council.province, p.toLong), 
          OrderBy(Council.name, Ascending)) 
     case _ => List() 
    } 
} 

// Council 
object council extends MappedLongForeignKey(this, Council) { 
    override def dbColumnName = "council_id" 
    val id = "council_select" 

    override def validSelectValues: Box[List[(Long, String)]] = 
     Full(((0l, "")) +: Council.findAll(By(Council.province, province), 
          OrderBy(Council.name, Ascending)). 
       map(c => (c.id.is, c.name.is))) 

    override def _toForm: Box[Elem] = Full(validSelectValues.flatMap{ 
     case Nil => Empty 
     case xs => Full(SHtml.selectObj(xs, Full(this.is), this.set, "id" -> id)) 
    }.openOr(<select id={id}/>)) 
} 

在編輯表格，當我改變列表上的省議會名單由省過濾器更換完美，但是當我保存建築物，councill不會首次保存/更新。接下來的時間，因爲全省已經安置，所以省下來，直到我省其他時間...所以，當我設立一個新的省份時，省政府並沒有得救，我需要省2次，省1次，省1次。理事會。

我認爲這個問題是因爲對象理事會的validSelectValues，是我第一次加載頁面時加載的，並且它將按省省過濾，或者在沒有設置省時省略空列表...我怎麼能當我更改省名單時，重新加載市議會validSelectValues？

感謝

嘗試用ajaxUntrustedSelect更換您的來電ajaxSelect。電梯中的正常選擇選項檢查提交的值是否可信，IE：它是生成頁面時可用的選項之一。如果您使用JavaScript或其他方式來改變列表，您可以通過使用該組件的Untrusted版本來避免該檢查。

我必須找到解決辦法...

object council extends MappedLongForeignKey(this, Council) { 
override def dbColumnName = "council_id" 
val id = "council_select" 

def selectValues: Box[List[(String, String)]] = province.obj match { 
    case Full(o) => Full(Council.findAll(By(Council.province, o), 
          OrderBy(Council.name, Ascending)). 
      map(c => (c.id.is.toString, c.name.is))) 

    case _ => Full((("0","")) Council.findAll(OrderBy(Council.name, Ascending)). 
      map(c => (c.id.is.toString, c.name.is))) 
} 

override def _toForm: Box[Elem] = Full(selectValues.flatMap{ 
    case Nil => Empty 
    case xs => Full(SHtml.untrustedSelect(xs, Full(this.is.toString), v => {this.set(v.toLong)}, "id" -> id)) 
}.openOr(<select id={id}/>)) 

}
