[web2py] WebGrid for Web2py and Keyerror

[winti]

Hello,
in a controller i define a temp db and want to return the results with
webgrid to a view.
I get a Keyerror on 'identity'.

Traceback (most recent call last):
  File "/data/projects/frameworks/web2py/applications/gluon/
restricted.py", line 178, in restricted
    exec ccode in environment

  File "/data/projects/frameworks/web2py/applications/gluon/sql.py",
line 1318, in __getitem__
    return dict.__getitem__(self, str(key))
KeyError: 'identity'




def xyz():

db=SQLDB('sqlite:memory:')
        db.define_table("identity",
                db.Field("user","string",default=""),
                db.Field("ip","string",default=""),
                db.Field("type","string",default=""))

...
...
....
db.identity.insert(user=user,ip=ipreadeable,type=type)
...
...

grid = webgrid.WebGrid(crud)
grid.datasource = db(db.identity.id<0).select()



Any idea
