Django表单值未插入sqlite3数据库表中

我是使用Django进行web开发的新手。 我已经创建了3个模型和相应的形式。即使makemigrations和migrate命令也没有报告任何问题，并且还在SQLite DB文件中创建了表。 但仍然没有将值插入到DB文件中。 收到空查询集，即

。 有人能告诉我为什么不插入值吗？提前谢谢

请帮助，提前谢谢。

必须查看您的表格，以便说明此处可能出现的问题。它的其余部分看起来不错，只是我不明白为什么你需要在那里尝试/except块，而且faculty\u info\u section.html似乎无关紧要。此外，我还建议浏览文档中的相应部分：有人能回答我的问题吗？！@安德烈·奥斯莫洛夫斯基：你能调查一下吗？一切看起来都很标准。打印更多内容，例如，

request.POST

查看查看函数获取的数据。确保执行

form.save（）

。为此，您可以在if/else块中插入如下行：

print（'request method is POST-idely'）

，

print（'form is valid'）

。基本上，您只需要小心，因为您的示例与文档中解释django表单的示例几乎相同。方法==Post没有输入有效的if代码，而是在else块中输入，而没有保存表单。您的

add\u faculty.html

是这样的吗<代码>{%csrf\u令牌%}{{form}}提交
