Question

我正在使用django表单向数据库添加新对象（页面），并在提交表单后我想重定向到页面详细信息的URL但问题是我没有页面的id正在创建。我是django的新手，所以请帮助我。

model.py文件

class UserPage(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    cover_page = models.FileField()
    page_name = models.CharField(max_length=250)

forms.py

from django import forms
from .models import UserPage

class PageForm(forms.ModelForm):
class Meta:
    model = UserPage
    exclude = ['user']
    fields = [
        "page_name",
        "cover_page"
    ]

view.py

def create(request):
if request.user.is_authenticated():
    if request.method=='POST':
        form = PageForm(request.POST , request.FILES)
        if form.is_valid():
            instance = form.save(commit = False)
            instance.user = User.objects.get(id=request.user.id)
            instance.save()
    else:
        form = PageForm()
    context = {
        "form" : form,
    }
    return render(request, 'pages/create.html', context)
else:
    messages.error(request, "please Login First")
    return HttpResponseRedirect(reverse('index'))

url.py

from django.conf.urls import url
from . import views
urlpatterns = [
    url(r'^(?P<page_id>[0-9]+)/$', views.pageDetail, name='pagedetail'),
    url(r'^create/$', views.create, name='create_check'),
]

是的，您确实拥有该ID：instance。

instance.save()
return redirect('pagedetail', page_id=instance.id)

提交表格后如何在网址中获取ID
