我应该如何编写views.py，以便如果用户的数据引发错误，而不是再次显示表单中的错误但没有原始数据，则会再次向其显示表单错误及其原始数据？

正如MYYN所说，请看这里：http://docs.djangoproject.com/en/dev/topics/forms/#using-a-form-in-a-view

ModelForms也是Forms，使用它们也没有什么不同。

if request.method == 'POST': # If the form has been submitted...
    form = ContactForm(request.POST) # A form bound to the POST data
    # now your form contains the values submitted
else:  
    form = ContactForm() # empty form

django表单应始终返回错误及其最初提交的数据。

如果您做了类似的事情，例如将空字典传递给表单，那么获取错误而不是数据的唯一方法就是。

您的示例永远不会显示任何错误，因为您从未传递数据以进行验证。它总是显示一个空的形式。

初始不是传递用户提交数据的地方

f = Form(initial={'foo':'bar'})
f.is_valid()
False
f.errors # will not validate or show you errors

传递POST词典

f = Form({'foo':'bar'})
f.is_valid()
False
f.errors
{'baz': [u'This field is required.']}

返回使用ModelForms时出现错误的表单的用户数据
