调用存储过程时出现错误“'DefaultConnectionProxy' 对象没有属性 'getitem'”

Question

您好，我正在使用 python/Django 创建一个项目，在我的第一页（索引）上，我正在调用一个存储过程来获取数据。

def index(request):
    listOPT = []
    Data = []
    fluxState = settings.FLUX_MANAGER_STATE
    if fluxState != True:
        listOPT.append('FLUX AXEREAL : OFF')
    cursor = connection['site'].cursor()
    """MS SQL CALL TO STORED PROCEDURE SP_webGET_RESUME_MVT_INIT_ACTIF """
    cursor.execute("{CALL SP_webGET_RESUME_MVT_INIT_ACTIF}")
    mouvements = cursor.fetchall()
    cursor.close()
    return render(request, 'index.html', locals())

但是在执行时我得到这个错误“'DefaultConnectionProxy' object has no attribute 'getitem'”

Exception Value: 'DefaultConnectionProxy' object has no attribute '__getitem__'

知道如何解决这个问题吗？我看到有些人不得不在他们的模型中添加一些 def __unicode__ 但它似乎对我不起作用。

看起来你应该使用 connections，而不是 connection。

from django.db import connections

cursor = connections['site'].cursor()
