Python REST mysql db.commit() error

Question

I am having the same error in python no matter where I put the db.commit() statement.

Here is my code:

from bottle import route, run
import json
import collections
import MySQLdb as db

@route('/register/<COD>/<NOMBRE>/<APELLIDO>/<DIRECCION>/<TEL>/<COD_FAC>', method='PUT')
def registrar(COD,NOMBRE,APELLIDO,DIRECCION,TEL,COD_FAC):
    c=db.connect('10.100.70.136','koala','toor','lab2',use_unicode=True)
    cur=c.cursor()
    sql1='SELECT * FROM alumnos WHERE codigo="'+COD+'";'
    cur.execute(sql1)
    alumnos=cur.fetchall();
    i=0
    for alumno in alumnos:
        i+=1
        print(i)

    if i==0:

        operationResult=1
        operationMessage=""
        cur2=c.cursor()
        sql2='INSERT INTO alumnos (codigo,nombre,apellido,direccion,telefono,codigoFacultad) VALUES ("'+COD+'","'+NOMBRE+'","'+APELLIDO+'","'+DIRECCION+'","'+TEL+'","'+COD_FAC+'");'
        cur2.execute(sql2)




    else:
        operationResult=2
        operationMessage="El alumno con codigo "+COD+" ya se encuentra registrado" 

    db.commit()
    db.close()
    results = []
    d=collections.OrderedDict()
    d['operationResult'] = operationResult
    d['operationMessage'] = operationMessage
    results.append(d)
    j = json.dumps(results)

    return j

run(host='localhost',port=8080,debug=True)

The error that I get is this:

AttributeError("'module' object has no attribute 'commit'",)

And the description that I get is the following:

Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/bottle-0.12.7-py2.7.egg/bottle.py", line 862, in _handle
return route.call(**args)

Answer 1

You want to call commit on the connection object - which is c in your case. (so make it c.commit() instead of db.commit())

You can find the python dbapi connection methods here.
