Python ValueError:以10为基数的int（）的文本无效：'；262400000'；

我正在开发一个Django应用程序，它从API获取JSON数据并将其存储在PostgreSQL数据库中。但在迁移应用程序时，我遇到以下错误：

ValueError: invalid literal for int() with base 10: '262,400,000'

以下是回溯：

这是我希望将JSON响应存储到postgres数据库中的API URL:

将逗号替换为

。

（python 3支持下划线）：

稍后再更改。

如果您将所有“金额”的db表数据类型更改为，那么您应该能够通过python将这些字段作为字符串插入，并保留逗号

俗话说，“如果你有一把又大又漂亮的锤子……”

因此，我使用sql函数将导入到数据库表中，然后这只是访问数据的方法之一：

上面有一些关于这个钉子的有用链接：）

实际上，Python不支持整数值中的数千个分隔符。首先删除这些逗号。我无法删除这些逗号，因为我正在将API中的数据存储到数据库中。是否有任何可选的Django字段，以便我也可以存储这些逗号？我使用了IntegerField（）…谢谢。我不明白为什么不能将数据存储为逗号整数。如果您从未打算将该值用作整数，请将其存储为字符串。然后使用预处理该值？或将其存储为字符串，因为它不是当前的有效整数。感谢您接受此答案。好奇：您将使用python还是深入研究SQL函数非常感谢您回答这个问题并解释dbfiddle:）为了回答您的问题，我将使用python..但不是我的选择。。我在做别人的项目
