我第一次使用Django Framework，而且还在建立在别人的代码上停止工作，所以我遇到了一些麻烦......
我正在尝试创建一个Web表单来向数据库提交数据但是收到错误消息'UserView' object has no attribute 'object'
models.py：
from django.db import models
class UserInfo(models.Model):
first_name = models.CharField(max_length=20, verbose_name='First Name', help_text='Your given name. *REQUIRED**')
last_name = models.CharField(max_length=100, verbose_name='Last Name', help_text='Your family name. *REQUIRED*.')
office_address = models.CharField(max_length=200 ,verbose_name='Office address', help_text='The address where you can be reached rather than your institution’s head office. *REQUIRED*')
research_interest = models.CharField(max_length=1000 ,verbose_name='Short summary of your research interests',help_text='In one or two sentences please describe your research interests and how access to the RD-Connect platform is relevant for you. *REQUIRED*' )
institution = models.CharField(max_length=50, verbose_name='Name of institution', help_text='The institution (university, hospital etc.) with which you have your primary affiliation. *REQUIRED*')
institute_website = models.URLField(max_length=100, null=True, blank=True, default="", verbose_name='Institute website', help_text='Your institution’s main website.')
job_title = models.CharField(max_length=100, null=True, blank=True, verbose_name='Position within institution', help_text='Your job title within your institution.')
email = models.EmailField(max_length=100, verbose_name='Institutional email address', help_text='Use of an institutional email address issued by your place of work is part of our validation procedure. If you do not have one please contact help@rd-connect.eu to explain your circumstances')

linkedin_profile = models.URLField(max_length=100,null=True, blank=True, verbose_name='LinkedIn profile', help_text='If you have a LinkedIn profile, please paste the link here.')
publications = models.URLField(max_length=100,null=True, blank=True, verbose_name='Three recent publications', help_text='Please paste links to three recent representative publications of which you are an author (link to the article on the journal website or to the PubMed page).')
researchgate_profile = models.URLField(max_length=100,null=True, blank=True, verbose_name='ResearchGate profile', help_text='If you have a ResearchGate profile, please paste the link here.')
departmentweb_profile = models.URLField(max_length=100,null=True, blank=True, verbose_name='Department web profile', help_text='If you or your group has a profile on your university or departmental website please paste the link here.')
adherence_agreement = models.FileField(verbose_name='Adherence Agreement', help_text='I confirm that I have read the Code of Conduct and signed the Adherence Agreement and agree to abide by the rules therein. In confirmation of this I upload a signed copy of the Adherence Agreement here.')
photo_scan = models.FileField(verbose_name='Photo ID scan', help_text = 'As part of our verification procedure we require a recognised form of ID such as your passport, national ID card or driving licence. Please scan, save and upload here as a JPEG or PDF.')
confirm_listing = models.BooleanField(verbose_name='I agree that my name can be listed as a user of the platform on the RD-Connect official website (https://rd-connect.eu)', help_text='All users will be stored in internal RD-Connect records for internal purposes and may be presented in reports to the European Commission as our funding organisation. We would also like to list users in a dedicated section of the platform website. If you do not wish your name to be listed publicly, do not tick the box.')
newsletter_subscribed= models.BooleanField(verbose_name='I would like to be subscribed to the RD-Connect Newsletter', help_text='We would like to register all users for our monthly newsletter in order to keep you updated about news of interest to rare disease researchers and platform updates. If you do not wish to receive the newsletter, please tick the box.')
created = models.BooleanField(default=False)
date = models.DateTimeField(auto_now_add=True, verbose_name='Date')
def __str__(self):
"""

return self.last_name
def get_absolute_url(self):
"""

"""
return reverse('user-detail', args=[str(self.id)])
forms.py：
from django import forms
from .models import Member, UserInfo
class UserForm(forms.ModelForm):
# Main registration form
def __init__(self, *args, **kwargs):
super(UserForm, self).__init__(*args, **kwargs)

fields = '__all__'
urls.py
from django.urls import path
from django.conf.urls import url, include
from django.views.generic import TemplateView
from .views import *
urlpatterns = [
url(r'^$', UserView.as_view(), name='user_new'),
url(r'^thanks/$', TemplateView.as_view(template_name='thanks.html'), name='thanks'),
]
views.py：
from django.shortcuts import render
from .forms import UserForm
from .models import UserInfo
from django.views.generic.edit import FormView,CreateView
class UserView(CreateView):
template_name = 'user_new.html'
form_class = UserForm
success_url = 'thanks/'
def post(self, request, *args, **kwargs):
form = UserForm(data=request.POST)
if form.is_valid():
form.save()
return self.form_valid(form)
else:
return self.form_invalid(form)
在此处查看类似帖子，我看到如果您覆盖post，则需要将object分配给视图，但我尝试在object = self.get_object()中添加views.py刚收到QuerySet错误......
这似乎也在Traceback中突出显示，我提交的表单无效？我输入了“有效”数据，所以也许我需要实现某种验证过程？：
C:\rdc-registration\rdcregistration\userregistration\views.py in post
def post(self, request, *args, **kwargs):
form = UserForm(data=request.POST)
if form.is_valid():
form.save()
return self.form_valid(form)
else:
return self.form_invalid(form) ...

答案 0 :(得分：2)
这是BaseCreateView中django/views/generic/edit.py的帖子功能：
def post(self, request, *args, **kwargs):
self.object = None
return super(BaseCreateView, self).post(request, *args, **kwargs)
如果您覆盖该功能，则应调用超级..或在代码中包含self.object = None。
