我正在django构建一个简单的社交网络。
在我的社交主页中，我有所有用户发布的所有帖子的列表，包括作者和发布日期。发布日期有一个指向url的链接，该链接应返回用户发布的特定帖子的详细信息视图。
然而，当我点击它时，它会向我显示作者发布的所有帖子的列表(当我点击帖子的作者链接时，这也适用(。
所以两个
www.mysocial.com/posts/by/ciccio/7/
和
www.mysocial.com/posts/by/ciccio/
把我带到同一页，那就是ciccio的帖子列表。
我将展示urls.py、views.py和models.py，它们都包含在我的"posts"应用程序(myproject>posts(中
这是我的urls.py
# shows all user posts
url(r'by/(?P<username>[-w]+)',
views.UserPosts.as_view(),
name='for_user'),
# shows specific post
url(r'by/(?P<username>[-w]+)/(?P<pk>d+)/$',
views.PostDetail.as_view(),
name='single'),
我的观点.py
class PostList(SelectRelatedMixin, generic.ListView):
model = Post
select_related = ('user', 'group')
class UserPosts(generic.ListView):
model = models.Post
template_name = 'posts/user_post_list.html'
def get_queryset(self):
try:
#prende i post fatti dal'username che è lo stesso di quello che è loggato per guardarli
self.post_user = User.objects.prefetch_related('posts').get(username__iexact=self.kwargs.get('username'))
except User.DoesNotExist:
raise Http404
else:
return self.post_user.posts.all()
def get_context_data(self,**kwargs):
context = super().get_context_data(**kwargs)
context['post_user'] = self.post_user
return context
class PostDetail(SelectRelatedMixin, generic.DetailView):
model = models.Post
select_related = ('user', 'group') #group senza apostrofo?
def get_queryset(self):
queryset = super().get_queryset()
return queryset.filter(
user__username__iexact=self.kwargs.get('username'),
# maybe smth is needed here?
)
我的型号.py
User = get_user_model()
# Create your models here.
class Post(models.Model):
user = models.ForeignKey(User, related_name="posts", on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now=True)
message = models.TextField()
message_html = models.TextField(editable=False)
group = models.ForeignKey(Group, related_name="posts", null=True, blank=True, on_delete=models.CASCADE)
def __str__(self):
return self.message
def save(self, *args, **kwargs):
self.message_html = m.html(self.message)
# in questo modo quando si fa un markdon si mette un link nel loro post
super().save(*args, **kwargs)
def get_absolute_url(self):
return reverse('posts:single', kwargs={'username':self.user, 'pk':self.pk})
class Meta:
ordering = ['-created_at']
unique_together = ['user', 'message']
我的模板显示了一篇文章的作者和发布日期：
<span class="username">
<!-- mi porta a tutti i post fatti da quell'user -->
<a href="{% url 'posts:for_user' username=post.user.username %}">@{{ post.user.username }}</a>
</span>
<a> – </a>
<!-- il time tag posta il tempo -->
<time class="time">
<a href="{% url 'posts:single' username=post.user.username pk=post.pk %}">{{ post.created_at }}</a>
</time>
"用户"模型是django的默认模型。用户
问题一定在PostDetail视图中，因为我通过点击url验证了这一点，我的模板显示了帖子正确的pk(post.pk(
视图中可能缺少筛选器？查看我的#comment
第一个url:末尾缺少/$
url(r'by/(?P<username>[-w]+)/$',
views.UserPosts.as_view(),
name='for_user'),
但我仍然无法理解，用于显示所有用户帖子的视图的url如何会影响应该只显示特定帖子的url的行为。
