Hmm, I'm not sure if DirectoryResource is quite what I need for this
problem ... but I'll try and explain what I'm trying to do a bit more.
I've got a package (gum, an app providing a web interface for an LDAP
install) and it has EditForm's which use a custom template
(gum_edit_form.pt). I had this template in the root of the package,
and could just read it using:
template = grok.PageTemplateFile('gum_edit_form.pt')
Then I wanted to extend the gum package with some views that were
specific to the requirements of a particular installation (when a user
is added to a certain group, then a JIRA account would be remotely
created). I put this in a different package, but wanted to use the
same custom edit form. I created a DirectoryResource (named
that the template is using between the two packages easily enough. But
I also wanted to share the template file as well, so I put it into the
resources directory and wrote:
template = grok.PageTemplateFile('resources/gum_edit_form.pt')
template = ???
css between pacakges I figured it might make sense to share templates?
I couldn't easily determine how to do this though - I can get at the
template inside the resources, and feed it into a grok.PageTemplate()
call by manually open()ing the resource, but that's pretty messy - but
maybe DirectoryResources are only intended for resources which should
be published to the web, and isn't really the right tool for template
