基于类别的详细信息视图返回同一页面

Question

我正在构建一个相册应用程序。用户可以在哪里登录并创建类别并在这些类别中添加照片帖子。

单击发布链接时，它应该使用deledView的使用打开帖子，它只需循环回到用户的帖子历史页面，带有邮政链接

我一直在尝试使用各种方法来过滤QuerySet并返回数据，但我没有在哪里出错。

posts/models.py：

    class Post(models.Model):
        user = models.ForeignKey(User, related_name='posts',on_delete=models.CASCADE)
        created_at = models.DateTimeField(auto_now=True)
        post_title = models.CharField( max_length=30)
        post_message = models.TextField()
        postimage = models.ImageField(upload_to='postimgs/',verbose_name=('post picture'))
        category = models.ForeignKey(Category, related_name='post_category', on_delete=models.CASCADE)
        def __str__(self):
            return self.post_title
        def save(self,*args,**kwargs):
            self.post_message_html = misaka.html(self.post_message)
            super().save(*args,**kwargs)
        def get_absolute_url(self):
            return reverse('posts:single', kwargs={"username":self.user.username,"pk":self.pk})

        class Meta:
            ordering = ['-created_at']
            unique_together = ['user','post_title']

posts/views.py：

    class PostDetail(SelectRelatedMixin, generic.DetailView):
        model =models.Post
        select_related = ('user', 'category')
        def get_queryset(self):
            queryset = super().get_queryset()
            return queryset.filter(user__username__iexact=self.kwargs.get('username'))

posts/urls.py：

    app_name = 'posts'
    urlpatterns = [
    url(r'^$',views.PostList.as_view(),name='all'),
    url(r'new/$',views.CreatePost.as_view(),name='create'),
    url(r'by/(?P<username>[-w]+)',views.UserPosts.as_view(),name='for_user'),
    url(r'by/(?P<username>[-w]+)/(?P<pk>d+)/$',views.PostDetail.as_view(),name='single'),
    url(r'delete/(?P<pk>d+)/$',views.DeletePost.as_view(),name='delete'),
    ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

html：

      <a href="{% url 'posts:for_user' username=post.user.username%}">@{{post.user.username}}</a>
        </span>
        <time class="time">
          <a href="{% url 'posts:single' username=post.user.username pk=post.pk %}">
            {{post.created_at}}
          </a>

单击{{post.created_at}}后，应打开带有详细信息的帖子详细信息，但它在邮政列表页面中循环

您的QuerySet缺少comma(',')

def get_queryset(self):
        queryset = super().get_queryset()
        return queryset.filter(user__username__iexact=self.kwargs.get('username'),category__categoryname__iexact=self.kwargs.get('categorynamee'))

更改您的URL，然后添加^ Infront

url(r'^new/$',views.CreatePost.as_view(),name='create'),
url(r'^by/(?P<username>[-w]+)',views.UserPosts.as_view(),name='for_user'),
url(r'^by/(?P<username>[-w]+)/(?P<pk>d+)/$',views.PostDetail.as_view(),name='single'),
url(r'^delete/(?P<pk>d+)/$',views.DeletePost.as_view(),name='delete'),
