this is  the  fonction :

    @api.one

def importation_automatique(self):

# connexion avec la base statagris

conn_stat = psycopg2.connect(database="db_statagris", user="openpg", password="openpgpwd", host="localhost", port="5432")

print ("Opened database statistic1 successfully")

cursor = conn_stat.cursor(cursor_factory=psycopg2.extras.DictCursor)

cursor.execute("SELECT * FROM statistic")

rows = cursor.fetchall()

conn_stat.commit()

# connexion avec la base odoo

con_odoo = psycopg2.connect(database="frma", user="openpg", password="openpgpwd", host="localhost", port="5432")

curr_stat = con_odoo.cursor()

print ("Opened database odoo successfully")

#fout = open('tempo', 'w')

#cur.copy_to(fout, 'tempo', sep="|")

#print ("file created successfully")

curr_stat.execute("TRUNCATE TABLE ml_stat ")

for row in rows:

curr_stat.execute("""insert into ml_stat values (%s,%s,%s,%s)""",( row["unid"],"2016-05-13 15:15:20.264",row["occurrence"], row["variante2_valeur"]))

print( '%s' % ( row["unid"]))

con_odoo.commit()

and here's the form I want the data to be loaded:
