accessing custom properties with JavaScript

paullewon — Thu, 23 Aug 2007 20:52:32 GMT

I have a custom aspect defined as follows: <aspects> <aspect name="cu:sourceInformation"> <title>Source Information</title> <properties> <property name="cu:sourceTitle"> <type>d:text</type>

FreeMarker is very strict on 'null' values - if that property does not exists on a document and returns 'null' it will cause that error I think.

I've not tried the syntax you are using, but you have something similar for 'description':
${child.properties.description!""}

which i assume means to display "" if the value is missing i.e. null. Can you try something similar for the 'cu:isbn' value?

We normally use the ?exists built-in to filter out missing values.

Thanks,

Kevin

Kevin,

Thank you. The following syntax works:

${child.properties["cu:isbn"]!""}

As does:

<#if child.properties["cu:isbn"]?exists>${child.properties["cu:isbn"]}<#else></#if>

Thanks again,

Paul

Hello,
IÃ¢â‚¬â„¢m trying to show all the aspects of a space. IÃ¢â‚¬â„¢ve extended the model adding new aspects to all the items in a space. This is what I meant:

   Name:   Expediente 1
       Title:   Expediente 1
       Description:
       Creator:   admin
       Created Date:   5 September 2007 14:54
       Modifier:   admin
       Modified Date:   5 September 2007 14:56

     Propiedades del expediente
       Identificador del expediente:   1
       Procedimiento:   Reclamaci
       Fecha de entrada:   1 June 2007
       Fecha de fin:
       Cuantia en euros:   1200000
       Asunto:   fff

IÃ¢â‚¬â„¢ve added an aspect "Propiedades del expediente" with all the properties showed below.

I want to have a template to show all this properties, and this is what IÃ¢â‚¬â„¢ve tried:

-   IÃ¢â‚¬â„¢ve tried to show space.aspects
-   IÃ¢â‚¬â„¢ve tried to show space.properties
-   IÃ¢â‚¬â„¢ve tried to guess if the space.hashaspect called, for example Ã¢â‚¬Å“customrocedimientoÃ¢â‚¬

The space.aspects simply returns the names of all the aspects that have been applied to a node - it does not return the values of the properties that are defined by those aspects. The node.properties map contains all the properties that have been set a value on that node - if they have not been set, then will not be in the map.

Something like node.properties["custom:myprop"] will show the value of the property called "custom:myprop" - you do not need to reference the name of the aspect at all. You just reference the properties you need directly and it will work. This example (copied from the Template wiki guide page) shows all properties for a node:


 <table>
 <#– Get a list of all the property names for the document –>
 <#assign props = document.properties?keys>
 <#list props as t>
    <#– If the property exists –>
    <#if document.properties[t]?exists>
       <#– If it is a date, format it accordingly–>
       <#if document.properties[t]?is_date>
       <tr><td>${t} = ${document.properties[t]?date}</td></tr>
       
       <#– If it is a boolean, format it accordingly–>
       <#elseif document.properties[t]?is_boolean>
       <tr><td>${t} = ${document.properties[t]?string("yes", "no")}</td></tr>
       
       <#– Otherwise treat it as a string –>
       <#else>
       <tr><td>${t} = ${document.properties[t]}</td></tr>
       </#if>
    </#if>
 </#list>
 </table>
