Django表单数据在mysql数据库中不提交/不可见

我使用连接到MySQL数据库的SessionWizardView设计并构建了一个Django 1.6.2调查应用程序

问题是（据我所知）提交的表单数据没有保存到数据库中。这是我第一次构建这样的应用程序，甚至是使用数据库

有人能看看我做了什么和我的代码，并指出我犯了什么错误，为什么我看不到我的调查表提交的任何内容吗？

有人告诉我需要为数据创建一个模型，有人建议我使用

ModelForm

在数据库中创建表和列。我已经这样做了，但我仍然没有看到我提交的内容

我的过程

• 我通过 终端

  创建数据库django_数据库和其中的表被创建
  当我运行命令
  python manage.py syncdb
  时
  

• 我可以在本地计算机和公共服务器上完成调查。没有错误，看起来一切正常

• 我已经设置了phpMyAdmin，可以看到django_db数据库和

  survey_person

  模型。然而，我似乎找不到任何应通过表格提交的数据

• 我曾尝试使用phpMyAdmin中的搜索功能查找我提交的任何表单数据，但无法查看

• 我已将数据库导出为.CSV文件，但它是空的

• 如果我在phpMyAdmin中使用insert工具，数据将保存在数据库中，我可以在使用搜索工具时返回它。导出CSV文件时，CSV文件中也存在相同的数据

这似乎表明，在向数据库提交内容时，我的应用程序中缺少了一个步骤

谁能告诉我哪里出了问题

我的代码 我已尝试将以下内容限制为仅适用于相关代码

设置.py
