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。
问题在于(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。
有人可以看看我做了什么和我的代码,并指出我为什么看不到我的调查表提交的任何内容的错误?
The last time I posted a similar question我被告知我需要为数据创建一个模型,并建议我使用ModelForm
在数据库中创建表和列。我已经这样做但我仍然没有看到我提交的内容
我在MySQL(Ver 14.14 Distrib 5.6.20)中创建了数据库
终端CREATE database django_db;
及其中的表格已创建
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。但是,我似乎无法找到表单应提交的任何数据。
我曾尝试使用phpMyAdmin中的搜索工具查找我提交的任何表单数据但看不到它
我已将数据库导出为.CSV文件,但该文件为空。
如果我在phpMyAdmin中使用插入工具,数据将保存在数据库中,我可以在使用搜索工具时返回它。导出时,CSV文件中也会显示相同的数据。
这似乎表明,在向数据库提交内容时,我在应用程序的某处错过了一个步骤。
谁能告诉我哪里出错了?
我试图将以下内容仅限于相关代码

来自phpMyAdmin的数据库的屏幕截图。注意:开头的隐藏字段不是调查表单中的介绍步骤,为简洁起见,此处未显示代码。
答案 0 :(得分:1)
将数据提交到模型表单不会导致自动保存。如果要将模型表单中的数据保存到数据库,则需要调用其save()
方法。您可以在向导的done()
方法中执行此操作。
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],
})
