Can you add a field introduced by schemaextender as a catalog column?

AnthonyG () Can you add a field introduced by schemaextender as a catalog column?

Reply Threaded

Hi,

I've added a field to news items using archetypes.schemaextender and I'd like to add it as a column to my site's catalog. When I try this is doesn't seem to have any effect. Catalog brains return type "Missing" when I try to access the new column. I've tried re-indexing all my indices and also updating news items TTW after adding the column and now I'm wondering whether this is even possible.

We're using Plone 3.3.1 and archetypes.schemaextender 1.1.

Thanks in advance

Anthony

Try to write an method getFoo() return the related value to be indexed
and attach it to the original class
(e.g. using dm.reuse). Then try to add an index called 'getFoo'.

I do not know if it helps but do not forget that the default accessor to an attribute with AT is "getMyAttribute", so, if you added a metadata, add it like "getMyAttribute" and not "myAttribute"...

Have a nice day,

Sorry, that's nonsense. Fields introduced using at.schemaextender have *NO* such auto-generated methods.

Indexing works OK. I've attached an index to my new field and catalog searches for that index work fine. What doesn't work is retrieving metadata from the catalog column.

e.g. Below just a set of blank lines from 'Missing' type are output

for brain in catalog(myField = someValue):
# some results returned
print brain.myField

I have both an index (portal_catalog/Indexes) and a column (portal_catalog/Metadata) set-up for the new field. Will the approach below will work for retrieving the metadata as well?

Use plone.indexer to write a custom indexer that does something like

return context.Schema()['myfield'].get(context)

Thanks for everyone's responses. I opted for Martin's approach as plone.indexer is included in Plone 3.3 and it worked a treat.
