Question

我正在尝试获取包含数据库中某些数据的网址，但我一直收到此错误：

 self = <django.db.backends.sqlite3.base.SQLiteCursorWrapper object at 0x7f01c35c2d38>
query = '        SELECT cust.id, cust.name, inv.currency_id, SUM(inv.total)\n        FROM\n          v3_customer as cust\n    ...        and inv.invoice_date < ?\n        GROUP BY cust.id, inv.currency_id\n        ORDER BY cust.id, inv.currency_id'
params = [(1,), '2016-12-04']

    def execute(self, query, params=None):
        if params is None:
            return Database.Cursor.execute(self, query)
        query = self.convert_query(query)
>       return Database.Cursor.execute(self, query, params)
E       sqlite3.OperationalError: near "?": syntax error

../../../environments/tracerenv/lib/python3.4/site-packages/django/db/backends/sqlite3/base.py:337: OperationalError

这是我的代码：

response = admin_client.post(
        reverse('report_create') + '?report_type=1',
        {

            'start_date': datetime.datetime.now().date() - datetime.timedelta(days=180),
            'end_date': datetime.datetime.now().date() + datetime.timedelta(days=180),
        }
    )
    print(admin_client.get(Report.objects.first().get_absolute_url()))

我在这里发现它失败了：

 PRE_INV_Q = """\
    SELECT cust.id, cust.name, inv.currency_id, SUM(inv.total)
    FROM
      v3_customer as cust
      JOIN v3_customerproxy ON cust.id = v3_customerproxy.original_id
      JOIN v3_invoice as inv ON v3_customerproxy.id = inv.customer_id
    WHERE
      cust.id IN %s
      and inv.type = 'i'
      and inv.invoice_date < %s
    GROUP BY cust.id, inv.currency_id
    ORDER BY cust.id, inv.currency_id

从我所看到的你convert_query方法只是替换查询中的参数。请尝试使用%s代替?。

尝试获取url页面时出现OperationalError
