I have a working app since web2py 1.99 times, and I have been upgrading to
later versions periodically. Today I noticed my app does not work in 2.5.1
in some simple uses of SQLFORM.smartgrid. I took time this morning to check
versions from 2.3.2 up to latest to check in which version it stopped
working. It works up to 2.4.2. In 2.4.3 it does not, up to the latest
2.5.1. In the non working versions the ticket message is the same, so the
code should have been introduced in 2.4.3. The message reads:
'Table' object has no attribute 'content_of_some_parent_field'
Take this simple model:
db.define_table('route',
Field('route', label=T('Route')),
format='%(route)s')
db.define_table('subroute',
Field('subroute', label=T('Subroute')),
Field('route', 'reference route', label=T('Route')),
format=lambda subroute: '%s-%s' % (db.route[subroute.route].route,
subroute.subroute))
Take this simple route.py controller:
@auth.requires_membership('Manager')
def index():
db.subroute.route.writable = False
grid = SQLFORM.smartgrid(db.route)
return locals()
Navigate to localhost:8000/appname/route. Create a route (parent record).
Click subroute (child link). Add subroute (child record). Now the grid is
showing the subroute (child) with an active link to its route (parent).
Click this link. It works on or below 2.4.2. It does not work on or above
2.4.3. When working, it allows to view/edit/delete the parent.
Should I file a bug or this is a known bug/expected behavior?
