Memento / struct of property values

[Nando]

Is there a way in CF's implementation of hibernate to get a struct of property names/values from an entity? I'm going to need this several times over within my current app to return a JSON string and was wondering ...

Thanks,

Nando

Can't you just getMetaData() on the entity?

I don't think there is a direct way of doing it but you could do something like this:

    <cffunction name="getMemento" output="false" returntype="struct">

   <cfset var properties = ORMGetSessionFactory().getAllClassMetadata()[ ListLast( GetMetaData( this ).fullname, "." ) ].getPropertyNames()>

   <cfset var memento = {}>

   <cfset var result = "">

   <cfloop array="#properties#" index="item">

   <cfinvoke component="#this#" method="get#item#" returnvariable="result">

   <cfif IsNull(result)>

   <cfset memento[item] = "">

<cfelse>

   <cfset memento[item] = result>

    </cfif>

     </cfloop>

   <cfreturn memento>

</cffunction>

As ColdFusion doesn't understand null, I'm just setting an empty string but you could alternatively ignore the key from your struct depending on your needs. Does that help?

You could just use serializeJSON(  ent ) to do this.

Oh, now that is nice :) 

So you could have this in an abstract entity if you want to get a struct back:

public struct function getMemento(){

  return DeserializeJSON(SerializeJSON(this));

}

much better than my suggestion! Only thing with using this is that null values are ignored, which does make sense but is worth remembering.

Thanks for the suggestions!

Oh sorry - didn't see "/values" in the original question. ;)
