I am trying to following the example query here
```
AssetVersion where asset.parent.project.name is "project_code" or parent.name is "project_code"
```
My project name is "magician" when I try this out
project_code = 'magician'
assets = session.query('AssetVersion where asset.parent.project.name is "{project_code}" or parent.name is "{project_code}"'.format(project_code=project_code)).all()
for asset in assets:
print(asset['name'])
I get the following errors
```
Server reported error: KeyError(u"No attribute parent exists for schema u'AssetVersion'.")
NoneType: None
