just so I can understand fully can you modify the paste I sent to illustrate exactly how the results are happening, as that can help me to formulate the best version of this feature. and yes the function is used in the ORM for the case where its inconvenient to use use_labels, specifically here where the old polymorphic_union function matches things up on column names. That function isn't needed except for a very fringe use case, which I eventually want to roll into a more flexible polymorphic system that wouldn't need to use UNION with joins. > > > I have refactored the code and now it works without problems. > I use both the select method on the Join instance (when the plugins does > not need to modify the query object), and the util.folded_equivalents > function by hand. > > > I have read the ticket 1131, and it seems that the folded_equivalents > function was used, in the ORM, for exactly the same reason as I'm doing > now. > > So, it seems that nobody is doing this without using the ORM. > Is it a problem to revoke the deprecation on the folded_equivalents? > I don't think I can go without it. > > > > Thanks Manlio > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.10 (GNU/Linux) > Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org > > iEYEARECAAYFAkt7Gc8ACgkQscQJ24LbaUTztQCcC//niqKT21umxaKCXEy4kcPl > mWYAoIP4k2kh4awv7EuJgppKwS1jXu/1 > =45t9 > -----END PGP SIGNATURE----- > > -- > You received this message because you are subscribed to the Google Groups > "sqlalchemy" group. > To post to this group, send email to sqlalch...@googlegroups.com. > To unsubscribe from this group, send email to > sqlalchemy+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/sqlalchemy?hl=en. > > -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
