Your model wasn't clear but... I had a pretty bad case of the 'NoneType' bug with a v. simple model containing one foreign-key. It seems that for foreign-keys, multiple-joins etc., the order of table creation is important. So if table b has foreign key of type a, table a should be created before b. 'tg-admin sql create' isn't that smart in this regard so it's better to create the tables explicitly with 'table.createTable(ifNotExists=True)', usually placed at the end of model.py. Confusingly some of the common doc examples (TurboTunes from memory) show both methods. You then bypass 'sql create' and let the database tables be created automatically (i think) by, for example, first use of catwalk.
Trying both methods on my simple model showed a difference in order of table-creation (comparing dropped text-files). I can't be sure this was behind the 'NoneType' bug - nature of that indeterministic beast - but my db seems more stable at the moment. I did a few slash, burn, reinstalls for TG in the meantime but have same version as before. I'm running XP, 0.94a, sqlite. Just a thought, and no tg, db guru i, but might be worth a punt if you haven't tried it, k Steve Bergman wrote: > Although I had run: > > easy_install -Uf http://www.turbogears.org/preview/download/index.html > --script-dir /usr/local/bin TurboGears[exp] > > (after correcting the problem I had with easy_install using pythong > 2.3) I still had TGFastData 0.9a3. > > I deleted that (and Turbo*, and everything else that looked related to > TurboGears) from site-packages and re-ran easy_install.
