[Massimo Di Pierro]

web2py 2.15.2 is OUT is includes a few major bug fixes to version 2.15.1. Thanks Leonel for the quick fixes.

There a few other outstanding problems and they will be resolved in the next week.

For new users 2.15.2 is still better than previous versions. For current users, please check it out and continue to report any problem. We want to make sure it is backward compatible as promised.

found an error that the same code didn't throw an error in previous version 2.15.1

Traceback (most recent call last):

AttributeError: 'Table' object has no attribute 'clone'

thanks and best regards,

[Leonel Câmara]

Stifan that error is caused because you're putting a Table in common_fields. Which I didn't expect. I'll fix it.

[Leonel Câmara]

@stifan here's the fix if you want to apply it on your running code before the new version comes out

OperationalError: table "auth_user" already exists

step i took for testing from git

@stifan seems like you need a fake migrate to fix your table files.

[黄祥]

yes, you are right, fake_migrate_all=True in db.py fixed the auth_user table exist's problem and the clone problem didn't appear again

[tim.n...@conted.ox.ac.uk]

Creating a SQLFORM.factory() from tables, or a combination of tables and fields, now breaks, because the underlying logic assumes the tables are fields:

form = SQLFORM.factory(idb.catering, idb.catering_diet)

File "/home/www-data/internal-apps/gluon/sqlhtml.py", line 1922, in factory
    return SQLFORM(DAL(None).define_table(table_name, *[field.clone() for field in fields]),

AttributeError: 'Table' object has no attribute 'clone'

[tim.n...@conted.ox.ac.uk]

Actually, this should be simple enough that I can post a fix.

[Massimo Di Pierro]

Thank you Tim.
