您的代码中存在一些问题，可能会导致此问题。对于每个字段，您将创建两个入口点。例如，“about me”有两个字段，由于else/if语句的缘故，这两个字段是相同的。所有字段都是一样的，你在复制所有内容 要捕获错误，实际上应该使用宏。您不应该向else/if语句添加额外的{{form.fieldname}} 我会移除这些，看看它是否有效
现在，Flask如何知道用户提交时使用哪个字段？当有两个字段可供选择时？可能是您的代码存在一些问题导致了此问题。对于每个字段，您将创建两个入口点。例如，“about me”有两个字段，由于else/if语句的缘故，这两个字段是相同的。所有字段都是一样的，你在复制所有内容 要捕获错误，实际上应该使用宏。您不应该向else/if语句添加额外的{{form.fieldname}} 我会移除这些，看看它是否有效
