所以我有一个页面包含一个表单，以便用户可以使用指定的pk值向数据库提交数据，第二个页面包含该记录中的特定字段。
我的问题是，我是否可以使用提交按钮将数据发布到数据库，然后立即使用该提交记录中的pk值加载URL 以使用某些字段？或者这需要分两步完成？即1.将数据插入DB，然后2.使用相关的pk加载URL ..
urls.py ：
from django.urls import path
from django.conf.urls import url, include
from django.views.generic import TemplateView
from .views import *
from . import views
urlpatterns = [
url(r'^$', UserView.as_view(), name='user_new.html'),
# form temporarily directs here after saving the data to the DB
url(r'^thanks/$', TemplateView.as_view(template_name='thanks.html'), name='thanks'),
# I would like it to go here instead
path('adherence_agreement/<int:id>', views.adherence_agreement, name='adherence_agreement'),
]
views.py ：
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):
self.object = None
if request.method == 'POST':
form = UserForm(data=request.POST)
if form.is_valid():
form.save()
return self.form_valid(form)
else:
return self.form_invalid(form)
else:
form = UserForm()
def adherence_agreement(request, id):
item = get_object_or_404(UserInfo, pk=id)
return render(request, 'adherence_agreement.html', {'item': item})
目前，点击“提交”按钮后，信息会正确保存到数据库中，并显示“谢谢！”的基本页面。显示（thanks.html）。此外，如果我输入网址http://127.0.0.1:8000/userregistration/adherence_agreement/6，它会将我带到从该记录中提取某些字段的页面（我根据数据库中的记录手动输入URL中的6）。
adherence_agreement.html ：

<li>Publications using any form of data accessed through the RDC-GPAP will contain an acknowledgment and a reference of the RDC-GPAP as appropriate.
Where a publication makes use of individual-level datasets and enriched phenotypic data, authors should consider whether the intellectual contribution of the original contributors of the datasets qualifies for authorship positions in line with standard publication practice.</li>
<li>Results of analyses of accessed data and biospecimens will be returned to the platform. Published work will also be sent to RD-Connect.</li>
<li>In case of misconduct access to the platform will be withdrawn.</li>

您应该覆盖get_success_url类
UserView方法
def get_success_url(self):
return reverse('adherence_agreement', kwargs={'id': self.object.id})
