我正在尝试使用CreateView,这是一些问题,我正在将其堆叠。
enter code here
首先,我正在尝试创建帖子并动态填充创建帖子的用户字段。它保存了帖子,但不保存用户:

#views.py
class PostCreateView(CreateView):
model = Post
template_name = 'blog/post_create.html'
fields = ('title', 'slug', 'body',)
def form_valid(self, form):
form.instance.blog__user = self.request.user
return super(PostCreateView,self).form_valid(form)
#models.py
第二个问题,我认为是主要问题,我没有正确使用get_absolute_url,却遇到了这个问题:
没有要重定向到的URL。
但这对post_detail很有用。
class Blog(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
slug = models.SlugField(max_length=50)
def __str__(self):
return self.user.username
def create_blog(sender, **kwargs):
if kwargs['created']:
user_blog = Blog.objects.create(user=kwargs['instance'], slug=kwargs['instance'])
post_save.connect(create_blog, sender=User)
class Post(models.Model):
blog = models.ForeignKey(Blog, on_delete=models.CASCADE)
slug = models.SlugField(max_length=50, db_index=True)
title = models.CharField(max_length=120, db_index=True)
body = models.TextField(blank=True, db_index=True)
pub_date = models.DateTimeField(auto_now_add=True)
def get_absolute_url(self):
return reverse('post_detail_url', kwargs={'slug': self.slug,
'username': self.blog})
#urls.py
urlpatterns = [
path('<username>/create/', PostCreateView.as_view(), name='post_create'),
path('<username>/<str:slug>/', PostDetailView.as_view(), name='post_detail_url'),
path('<username>/', PostListView.as_view(), name='post_list_url'),
path('<username>/<str:slug>/update/', PostUpdateView.as_view(), name='post_update'),
]
我试图定义get_success_url,我得到了这个:NoReverseMatch
请帮助我,我真的迷失在云端!

尝试下面的代码
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[usp_SetRecordCheckStatus]
@pIntRecordKeyValue INT,
@pIntCheckBoxStatus INT
AS
BEGIN
SET NOCOUNT ON;
UPDATE dbo.Record
SET CheckState = @pIntCheckBoxStatus
WHERE Pno = @pIntCheckBoxStatus
END
GO
