psycopg2 not actually inserting data

Question

I need to insert JSON data from tornado to postgres, so here\'s test like this:

from psycopg2 import connect

conn = connect(\"user=\'pguser\' host=\'localho         


        

Answer 1

You didn't commit the transaction.

Psycopg2 opens a transaction automatically, and you must tell it to commit in order to make the data visible to other sessions.

See the psycopg2 FAQ and the connection.commit() method.

Answer 2

Just had the same perplexing issue. To put options together:

as @Craig Ringer writes after cursor.execute you can run connection.commit

cursor.execute('INSERT INTO table VALUES(DEFAULT, %s)', email)
...
connection.commit()

OR after connect set autocommit

connection = connect("user='pguser' host='localhost' dbname='pgdb' password='pgpass'")
connection.autocommit = True

OR use set_session to set autocommit

connection = connect("user='pguser' host='localhost' dbname='pgdb' password='pgpass'") 
connection.set_session(autocommit=True)

All worked for me.
