Error on inserting a content in Sidebar

[frague59]

Hi,

I'm starting a project with mezzanine + widgy, and I've followed the "first widget" tutorial.
I've build a NewsContainer, which will display News, based on rules about categories and publications dates.

Each News is a Content instance, but it is not registered with the @widgy.register decorator : it is administrated elsewhere.

The insertion of my NewsContainer works perfectly when I insert it into the Main content layout container, but it does not when I insert it into the Sidebar container...

I've the following error :

AttributeError: 'NoneType' object has no attribute '_inc_path'

I've tryied to insert other kind of widgets, but I've the same issue.

I've the same issue from main layout editor and from the "Pop out" editor .

Thanks for any help !

Hmm, it looks like the tree structure in the database might be corrupted. Can you open a shell and run:

from widgy.models import Node
Node.find_problems()
Node.find_widgy_problems()

I've reset the database, and rewinded the project, it looks OK (I'm actually in a realy starting project, so I can do that), but I keep your solution !

Thanks a lot :)
