Question

I have a field that I would like to be read-only and have a default value.

here what I have till now:

    object passwd extends MappedString(this, 20) 
    {
       override def defaultValue = "XXX" + Random.alphanumeric.take(12).mkString // some default value
//  readOnly = true // Or something similar??? 
    }

I tried overriding toHtml, asHtml, toForm, displayHtml but they all change the view or the label or something else.

I just want the defaultValue to be automatically generated (which works) but the users not to be able to edit that field when create/editing the entity.

Any advice would be very much appreciated

Got it,

Just override _toForm and disable the input element:

import net.liftweb.http.S

override def _toForm =  
    S.fmapFunc({s: List[String] => this.setFromAny(s)}){name =>  
    Full(<input disabled='disabled' type='text' id={fieldId} maxlength={maxLen.toString}  
    name={name}  
    value={is match {case null => "" case s => s.toString}}/>)}
