Python REST mysql db.commit（）error

Question

我在python中遇到了同样的错误，无论我放置db.commit（）语句。

这里是我的代码：

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) 

，我得到的错误是这样的：

AttributeError的（" '模块'对象没有属性'提交' "）

而我得到的描述如下：

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) 
File "/usr/local/lib/python2.7/dist-packages/bottle-0.12.7-py2.7.egg/bottle.py", line 1729, in wrapper 
rv = callback(*a, **ka) 
File "tarea.preg4.py", line 33, in registrar 
db.commit() 
AttributeError: 'module' object has no attribute 'commit' 

Answer 1

你想调用连接对象的提交 - 这就是你的情况下的c。 （所以使它c.commit()而不是db.commit()）

你可以找到蟒蛇dbapi连接方法here。
