Hi all,

How do I access "class variables" (properties defined in the folder of my Product - I know it is not strictly speaking class variables!) when I am rendering my class' add form? Each product must render a list of checkboxes in the add form to define parameters of the instance. I want to store that list of choices in a list in the product and then build the html when the product is added. That way I can easily change the list without having to write a lot of HTML code every time.

Here is what I have done so far:

I have the following product:

Control_Panel\Products\Indicator

In that folder (the product folder) I have a property that is called Pressures (a list of items) (ControlPanel->Products->Indicator->Properties Tab)

This means that Pressure is a class-ish variable (actually a creation-time variable, or whatever). I have a method in that folder called renderPressures (Control_Panel\Products\Indicator\renderPressures) which I want to use to render the list of pressures in the add form with checkboxes etc.

When rendering the addform for a user to add a new indicator (non Zope management interface) I do it as follows in Python script:

return context.manage_addProduct['Indicator'].Indicator_addForm(context)

This means that context is passed to the Indicator_addForm and that <dtml-var renderPressures> will not work since it is "bound" to context, so I use <dtml-var "manage_addProduct['Indicator'].renderPressures()"> instead.

renderPressures contains something like

pressures = context.getProperty('Pressures') (also tried container.getProperty('Pressures') )

but that returns None and

pressures = context.manage_addProduct['Indicator'].getProperty('Pressures') also returns None

Thanks

Etienne
