在另一个应用程序模板中包含一个应用程序的Django模板

Question

我试图在用户的个人资料中添加一个显示用户帖子的模板。我使用了包含标签但是帖子没有显示在用户的个人资料中。但它确实可以在主页上工作，该主页设置为该应用程序的PostListView。

userprofile_detail.html中的包含标记：

<div class="content-right">
    {% include 'feed/userpost_list_inner.html' %}
</div>

userpost_list.html中的帖子（Feed）的实际列表：

{% for post in userpost_list %}
    <div class="post">
        <h2 class="post-title">{{ userpost.post.title }}</h2>
        <p class="accent">{{ post.author }}</p>
        <p class="accent">{{ post.post_date }}</p>
        <p class="body">{{ post.post_body }}</p>
    </div>
{% endfor %}

我没有收到任何错误，但帖子没有显示在用户的个人资料页面上。

修改：这是我的Feed应用views.py：

from django.shortcuts import render,get_object_or_404,redirect
from django.utils import timezone
from feed.models import UserPost,UserComment
from feed.forms import PostForm,CommentForm

                                    UpdateView,DeleteView)

User = get_user_model()

# Create your views here.

    redirect_field_name = '/userpost_list.html'
    model = UserPost

        form.instance.author = self.request.user
        self.object = form.save(commit=False)

    success_url = reverse_lazy('userpost_list')

    def get_queryset(self):
        queryset = super().get_queryset()
        return queryset.filter(user_id=self.request.user.id)

    def delete(self,*args,**kwargs):
        return super().delete(*args,**kwargs)



##Comments Views

            return redirect('userpost_list',pk=userpost.pk)
        else:
            form = CommentForm()
        return render(request,'feed/userpost_list.html',{'form':form})

Answer 1

这是因为userpost中userprofile_detail.html对象不可用。它仅在userpost_list.html中提供。

通过使用视图将其发送到userprofile_detail.html使其可用，它将显示。

from feed.models import UserPost
from .models import UserProfileInfo
from django.shortcuts import render,get_list_or_404,get_object_or_404

def userprofile(request,pk):
    user = get_object_or_404(UserProfileInfo, user__id=pk)
    userpost_list = UserPost.objects.filter(author__id=pk)

    context={'user':user, 'userpost_list':userpost_list}
    return render(request, 'yourtemplate/html', context)

现在位于 urls.py

url(r'^(?P<pk>\d+)/$',views.userprofile,name='user_profile'),
