问题描述
在我的article_details.html页面中,我写了{{post.title}},但该页面未显示特定标题。我的应用程序名称是post,模型名称是BlogPost。 这是我的views.py:
from django.shortcuts import render
from .models import *
from .forms import *
from django.views.generic import ListView,CreateView
from django.views.generic.detail import DetailView
def home(request):
return render(request,'post/home.html')
class HomeView(ListView):
model = BlogPost
template_name = "post/home2.html"
class ArticleDetailView(DetailView):
model = BlogPost
template_name = "post/article_details.html"
class AddPostView(CreateView):
model = BlogPost
template_name = "post/add_post.html"
fields = '__all__'
这是我的urls.py
from post import views
from django.urls import path
from .views import HomeView,ArticleDetailView,AddPostView
app_name = 'post'
urlpatterns = [
path('',views.home,name="home"),path('home2/',HomeView.as_view(),name = "home2"),path('article/<int:pk>',ArticleDetailView.as_view(),name = "article-details"),path('add_post/',AddPostView.as_view(),name="add_post"),]
这是我的列表页面:post / home2.html
<ul>
{%for post in object_list %}
<li><a href="{%url 'post:article-details' post.pk %}">{{post.title}}</a>-{{post.author}}<br/>
{{post.body}}</li>
{%endfor%}
</ul>
这是我的详细信息页面:article_details.html:
<h1>{{post.title}}</h1>
<small>by:{{post.author}}</small><br/>
<hr>
<br/>
<p>{{post.body}}</p>
enter code here
解决方法
除非您定义context_object_name
,否则视图将通过所有小写形式的模型名称的上下文属性发送对象。因此,您应该通过{{ blogpost.author }}
获得价值。或者,您可以像这样更新视图:
class ArticleDetailView(DetailView):
model = BlogPost
template_name = "post/article_details.html"
context_object_name = 'post'
