Обсуждение: Python and 8.0 beta

Are there any python drivers that work with the version 8 beta?

The version seven ones didn't.

Thanks,
Tim

This script is working with version 7.4.2, FC2, python 2.3.3

#! /usr/bin/env python
import pgdb
db = pgdb.connect(dsn="localhost:ksDesenv")
cursor = db.cursor()
cursor.execute("select * from times()")
rsTimes = cursor.fetchall()
for lTime in rsTimes:
    i = 0
#    print str(lTime[0])
    cursor.execute("select * from usuarios_do_time(" + str(lTime[0]) +
")")
    rsMembros = cursor.fetchall()
    for lMembro in rsMembros:
        f = open('/var/www/html/kakaostats/u' + str(lMembro[0]) + '.txt',
'w')
        f.write(repr(lMembro[1]) + ';' + str(lMembro[2]) + ';' + lMembro[5] +
'\n')
        i += 1
#        print i, lTime[0], lMembro
        rank = lMembro[4]
        cursor.execute("select * from concorrentes_de_um_usuario(" +
str(lTime[0]) + "," + str(lMembro[2]) + "," + str(lMembro[3]) + "," +
str(rank) + ")")
        rsConcorrentes = cursor.fetchall()
        for lConcorrente in rsConcorrentes:
            if lMembro[2] - lMembro[3] > lConcorrente[6] - lConcorrente[7] and
lMembro[4] > lConcorrente[4]:
                rank -= 1
                rg = 'g'
            else:
                rank += 1
                rg = 'r'
            f.write(str(rank) + ";")
            for campo in lConcorrente:
                f.write(repr(campo) + ';')
            f.write(rg + '\n')
#            print rank, lConcorrente, rg
        f.close()
#        print raw_input(":")
cursor.close()
db.close()

Changed from using pyPgSQL to psycopg and things are working again...

Switching modules may fix your code but it doesn't fix the problem
with pyPgSQL.  I'm guessing that your code was failing with an
exception like the following:

libpq.DatabaseError: Ivalid [sic] format for PgVersion construction.

pyPgSQL's version string parsing fails at the "beta" portion
of "8.0.0beta1".  This has already been reported at Sourceforge
as Bug 1006782; I just followed up to that bug report with a
suggested fix.

May you test the following script and let me know which error you are encountering:


#!/usr/bin/python

import pgdb

if ( __name__ == "__main__") :
         connection = pgdb.connect(
                         user = 'user',
                         password = 'password',
                         host = '127.0.0.1',
                         database = 'database')

         if ( connection == None):
                 raise "Could Not Connect"

         cursor = connection.cursor()
         cursor.execute ( 'select version()' )
         result = cursor.fetchall()
         cursor.close()

         while ( type(result) is type([]) ):
                 result = result[ 0 ]

         print result



this is working correctly on my 8.0beta1 installation
