Exception Type: IndexError at /admin/
Exception Value: list index out of range

我为这个项目创建了虚拟环境并在那里安装了django1.3。请帮我解决这个错误。

Answer 1

让我们试着理解错误。根据回溯，错误发生在lfs/core/utils.py的以下行：

shop = Shop.objects.all()[0]

您的数据库中没有商店，因此all()方法返回一个空列表。因此错误，它试图获取空列表的第一个元素。

在能够使用此模块之前，您需要create at least one Shop。

Answer 2

添加上面的答案，特别是在返回数据值时，最好返回错误，或者在您的情况下，可能通过添加try / catch或任何其他机制来静默失败。

此外，在您安装的应用程序中，我认为您不需要添加所有内容，例如lfs就足够了。

在django 1.3中获取错误列表索引超出范围
