问题描述
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（尽可能请参阅）提交的表单数据未被保存到数据库。这是我第一次构建这样的应用程序，甚至使用数据库。
有人可以看看我做了什么，我的代码和点我所做的错误是为什么我看不到任何由我的调查表格提交的内容？
方法。您可以在向导的方法。
def done（self，form_list，** kwargs）：
＃我不知道这是否工作，我不熟悉你的表单。
form_list中的表单：
form.save（）
＃注意文档建议重定向而不是渲染模板。
return render（self.request，'return_to_AMT.html'，{
'form_data'：form_list中的form的表单，
}）
I designed and built a Django 1.6.2 survey application using a SessionWizardView which is connected to a MySQL database.
The problem is that (as far as I can see) the submitted form data is not getting saved to the database. This is my first time building an application like this or even working with a database.
Could someone take a look at what I have done and my code and point out any mistakes I have made as to why I cannot see any content submitted by my survey form?
The last time I posted a similar question I was told I needed to create a Model for the data and it was suggested I use a ModelForm to create the table and columns in the database. I have done this but I am still not seeing my submitted content
My Process
I created the database in MySQL (Ver 14.14 Distrib 5.6.20) viaTerminal
CREATE database django_db;and the tables in it are createdwhen I run the commandpython manage.py syncdb.I can complete my survey both on my local machine and on the public server. No errors and it appears everything works fine
I have setup phpMyAdmin and can see the django_db database and
survey_personmodel. However I can not seem to find any of the data that should be submitted by the form.I have tried to use the search facility in phpMyAdmin to find any of the form data I submitted but cannot see it
I have exported the database as a .CSV file but it is empty.
If I use the insert facility in phpMyAdmin the data gets saved in the DB and I can return it when I use the search facilities. The same data is also in the CSV file when I export it.
This seem to suggest that I am missing a step somewhere in my application when it comes to submitting content to the DB.
Can anyone tell me where I am going wrong?

phpMyAdmin
A screenshot of the DB from phpMyAdmin. NOTE: Not the hidden fields at the start are for introduction steps in the survey form, code not shown here for brevity.
Submitting data to a model form does not cause it to be saved automatically. If you want save data from a model form to the database, you need to call its save() method. You could do this in the wizard's done() method.
def done(self, form_list, **kwargs):
# I don't know whether this will work, I am not familiar with your forms.
for form in form_list:
form.save()
# Note the docs suggest redirecting instead of rendering a template.
return render(self.request, 'Return_to_AMT.html', {
'form_data': [form.cleaned_data for form in form_list],
})
