如何将 blog.models 中的 {{ post.title }} 用于 home_app 模板

Question

我想使用 {{ post.title }} 和 {{ for post in object_list }} 进入我的主页模板以显示最新的 4 个帖子，我尝试导入 from blog.models import Post，但它不起作用。我想我放错地方了。

blog.models

from django.db import models
from ckeditor.fields import RichTextField

class Post(models.Model):
    title = models.CharField(max_length = 140)
    image = models.ImageField(upload_to="media", blank=True)
    body = RichTextField(config_name='default')
    date = models.DateField()

    def __str__(self):
        return self.title

home.urls

from django.urls import path

from . import views

urlpatterns = [
    path('', views.HomePageView.as_view(), name='home'),
]

home.views

from django.views.generic import TemplateView
from allauth.account.forms import LoginForm

class HomePageView(TemplateView):
    template_name = 'home/index.html'

我的网站树看起来像这样

mysite
    home
        admin
        app
        models
        tests
        urls
        views
    blog
        admin
        app
        models
        tests
        urls
        views

您可以覆盖 get_context_data 并将最新的博文添加到模板上下文中。

from blog.models import Post

class HomePageView(TemplateView):
    template_name = 'home/index.html'

    def get_context_data(self, **kwargs):
        context = super(HomePageView, self).get_context_data(**kwargs)
        context['object_list'] = Post.objects.order_by('-date')[:4]
        return context
