[Zope] CatalogAwareBase doesn't auto-reindex?

[Laurie Nason]

Hi Bryan - sorry if you have this solved by now - but I didn't see any =
reply to the mail below.
What Chris is trying to say (I think) is that within the ZClass that you =
created, you need to create a dtml method that allows you to edit the =
properties of your ZClass.=20
Here's what I usually do:
---I copy the add form I use to add a new instance and paste it inside =
the ZClass object (in Products folder). (I tend to call mine =
index_edit_html).=20
---Inside this dtml method, I set the properties of the various text =
boxes, select lists etc to the values of the instance of the zclass.
---In the same place as where you copied the form you just created =
create another method (I call mine ZClassName_Update).
---Inside this method call the two functions that Chris mentioned=20
e.g.=20
    <dtml-call =
expr=3D"propertysheets.Basic.manage_changeProperties(REQUEST)">
    <dtml-call expr"reindex_object()">

hth,
Laurie

OK Chris,

I understand what you're saying. But my follow-on question is, where =
exactly can I find the code that is auto-generated from the properties =
interface? And if there is no such code, then is there a complete code =
sample, somewhere, of how I would code this myself? Your statement:

You need to create a custom properties-editing form with a target that =
calls reindex_object as well as modifying the properties."=20

isn't really enough for a newbie like me to pick up and run with.

I'm also unclear where this prebuilt form is being built -- is it when I =
define the property sheet, or instead is it when I create a view out of =
a property sheet?

Having fun getting to know this system!

Bryan

Hi Bryan,

Please keep the mail on the maillist, thanks.

This is a limitation when using prebuilt forms from the properties=20
interface.  The prebuilt propertysheet editing forms don't call=20
reindex_object.

You need to create a custom properties-editing form with a target that=20
calls reindex_object as well as modifying the properties.

You could make the target a Python Script or a DTML method, as long as=20
it calls the right stuff (manage_changeProperties and reindex_object) on =

itself with the right values.

HTH!
