Python psycopg2 not inserting into postgresql table

Question

I'm using the following to try and insert a record into a postgresql database table, but it's not working. I don't get any errors, but there are no records in the table. Do I need a commit or something? I'm using the postgresql database that was installed with the Bitnami djangostack install.

import psycopg2

try:
    conn = psycopg2.connect("dbname='djangostack' user='bitnami' host='localhost' password='password'")
except:
    print "Cannot connect to db"

cur = conn.cursor()

try:
    cur.execute("""insert into cnet values ('r', 's', 'e', 'c', 'w', 's', 'i', 'd', 't')""")
except:
    print "Cannot insert"

Answer 1

If don't want to have to commit each entry to the database, you can add the following line:

conn.autocommit = True

So your resulting code would be:

import psycopg2

try:
    conn = psycopg2.connect("dbname='djangostack' user='bitnami' host='localhost' password='password'")
    conn.autocommit = True
except:
    print "Cannot connect to db"

cur = conn.cursor()

try:
    cur.execute("""insert into cnet values ('r', 's', 'e', 'c', 'w', 's', 'i', 'd', 't')""")
except:
    print "Cannot insert"
