Django表单未提交数据
[英]Django form not submit data
问题描述
需要您的帮助来确定django应用程序中的表单出了什么问题，我的应用程序中有一个选项卡部分，其中包含三个选项卡（课程，练习簿，答案）。工作流程是用户浏览一些课程内容，然后单击一个“锻炼”按钮，该按钮将其带到“工作簿”选项卡。在这里，我有一些问题，可以根据课程选择多项选择题或简单问题，在完成练习后，用户提交问题，然后过渡到答案选项卡我的问题是，当单击提交按钮时，未提交答案，因此没有用户答案显示在答案选项卡中。
这是HTML代码

在处理不同的问题时，我遇到了非常相似的问题。 但我认为您的问题是相同的。
基本上问题是html代码。 我建议您在浏览器中验证生成的html代码，并检查表单标签是否正确关闭。 可能是表单标签关闭的时间早于html中数据的延迟时间，因此不会提交。 检查生成的html。
ajax django表单仅提交部分数据
