Programatically determine size of an class property in a Database List

The $field variable does contain the properties based on this:

https://www.xwiki.org/xwiki/bin/view/FAQ/Bindings%20available%20inside%20the%20Custom%20Display%20property

I was successful to retrieve properties like

$field.name
$field.prettyName
$field.Type

but was unable to identify the property to determine the size of the control (“size” in the UI).

Is this property available in the “$filed” object and if, what would the name be?

Thank you

Hi,

See https://xwiki.org/xwiki/bin/view/Documentation/DevGuide/Scripting/APIGuide/#HAccessobjectsinapage

You can test by writing the following in your custom display field:

{{velocity}}
#foreach ($prop in $field.getProperties())
* $prop.name - $prop.value
#end
{{/velocity}}

And you’ll see that the way to get the size is thus: $field.getProperty('size').value

Thx

Perfect, thank you very much!

Since some of the properties of $field (like name and prettyName) are accessible directly, I didn’t consider this.

Yes, it seems we don’t have specific direct apis for all property metadata.
