Question

I am developing a site in plone and am currently writing a form using python and z3c.forms

Currently I am using an interface to define form fields like…

class IMyInterface(Interface):

    name = schema.TextLine(
            title=_(u"Name"),
            default=_(u"Name")
        )

and then assigning to fields like…

fields = field.Fields(IMyInterface)

this is then rendered in a template using tal like…

<div tal:replace="structure python: view.contents" />

I would like to render an onfocus attribute within the markup of the input. Is there a way to do this?

You can give arbitrary HTML attribute parameters to z3c.form widgets in updateWidgets() phase of your form.
