I have code that's been working with an earlier version of 0.2
after svn up tonight I find this odd behaviour, that is table.c is busted
until the first
query is executed. Then that table starts working, but other tables are broken
too
until I perform a select on them.
Revision: 1654

I'm using sqlalchemy w/ python2.4 on windows with paste
table.c.keys() returns an empty list AND
this code fails on when building up the query (that is, table.c[k] raises an
error)
(for example, k='id')
args = []
if criteria:
for k, v in criteria.items():
args.append(table.c[k] == v)
# if there's no criteria or whatever, so they
# want everything. Need an extra arg to
# allow dumping everything
if args or form.get('selectall'):
records = table.select(*args)
However if I execute a query without any criteria first, THEN table.c.keys()
works
and table.c['id'] works
----
to clarify
1. start up paste app
2. try table.c['id'] == '1' and I get this exception:
File
'E:\\prj\\src\\eclipse\\parent_to_parent\\Web\\p2pserver\\p2pserver\\dbaccess.py',
line 66 in __call__
args.append(table.c[k] == v)
File 'e:\\prj\\src\\sqlalchemy\\lib\\sqlalchemy\\util.py', line 114 in
__getitem__
return self.__data[key]
File 'e:\\prj\\src\\sqlalchemy\\lib\\sqlalchemy\\util.py', line 174 in
__getitem__
return dict.__getitem__(self, key)
exceptions.KeyError: 'id'
3. or table.c.keys() returns []
4. then try table.select(*[]) that returns all rows in the table ok
5. and now table.c.keys() returns the columns and table.c['id'] works
6. try another table, and it's also broken until a select is performed.
