但你可以使用这个快速但丑陋的解决方案“monkeypatching”

# ugly monkeypatch
from sqlalchemy.dialects.sqlite.base import sqliteDDLCompiler

old_create_table = sqliteDDLCompiler.visit_create_table

def new_create_table(*args,**kwargs):
    sql = old_create_table(*args,**kwargs)
    # TODO 
    # 1) check table with FTS3 
    # 2) change sql to CREATE VIRTUAL TABLE ... USING FTS3(tokenizer=...)
    print 'sql: %s' % sql
    return sql

sqliteDDLCompiler.visit_create_table = new_create_table
# end of ugly monkey patch
