one more error in ACP, took me a day to find and separate.
it's very simple and very basic... ClauseAdapter does not work.
--------------
from sqlalchemy import *
from sqlalchemy.sql.util import ClauseAdapter
m = MetaData()
a=Table( 'a',m,
Column( 'id', Integer, primary_key=True),
Column( 'xxx_id', Integer, ForeignKey( 'a.id', name='adf',
use_alter=True ) )
)
e = (a.c.id == a.c.xxx_id)
print e
b = a.alias()
#print b.c.id == 0
r = ClauseAdapter( b, include= set([ a.c.id ]),
equivalents= { a.c.id: set([ a.c.id]) }
).traverse( e)
print e
######### results
#in r3726: (OK)
a.id = a.xxx_id
a_1.id = a.xxx_id
#in r3727 - as well as in r3760:
a.id = a.xxx_id
a.id = a.xxx_id
it does generate proper thing in ClauseAdapter.conv_element()/newcol but
it gets lost in the way
