[ckan-dev] genshi.template.eval.UndefinedError caused by db_to_form_schema()

[Adrià Mercader]

Hi Knud,
A plain 1.8 install and your extension does not give me any error, so
I suspect something else is going wrong.
Do you have any other extensions running which modify the templates or
the schema?

There are several places in various templates where model.package.isopen() is called (e.g., in templates/snippets/package_list.html). When I minimally implement db_to_form_schema() as below, these calls fail with a genshi.template.eval.UndefinedError ("… has no member named "isopen").

I have put together a minimal plugin which isn't doing much else than implementing this method, if you want to try to replicate this error:
