[SOLVED] schema.List problems indexing in the catalog

Plone Support Add-on Development

Hi,

I am upgrading from 5.0.4 to 5.2.2, as well as py2 to py3, and updating 16 addons.

I am running into a reoccurring issue in my addons with schema.List. I also have my schema.List declaration below being indexed in the catalog. It works fine in 5.0.4.

content_type = schema.List(
title=u"Restrict content types in this collection",
required=False,
value_type=schema.Choice(source=content_types),
)

When saving throws...

I have been trying and trying to figure out what is going on. When I comment out the content_type field in the Model, it saves fine. It is something with the schema.List not being able to be cataloged. This is happening to all my Lists schemas that are cataloged.

I upgraded my plone.app.z3cform package to 3.2.2 already.

Thank you,
David

That is in the standard mime_type indexer. This indexer expects that it can call content_type() on the object. This is a method in content.py. Your field name overrides this.

If you can rename your field, that should solve it.

Alternatively it should be possible to register your own mime_type indexer and register it for a more specific interface for your content, instead of IDexterityContent. That should avoid the direct error. I am not sure if you then run into other problems, where other code expects that it can call content_type().

Agh! You are 100% correct. Thank you!

I work in a library, we have almost identical naming conventions to the plone_catalog. Probably because the portal_catalog is based on Dublin Core. This probably explains why so many of my addons are conflicting in the catalog. So weird it never had a problem before.

Thank you!
