Python 如何在同一模板中呈现来自不同应用程序的视图？

我有两个应用程序（博客和分类）。在帖子列表模板上，我想获得类别博客的名称和描述

我曾尝试将导入类别模型放在博客视图中，但没有显示任何内容。因此，我制作了两个视图来呈现相同的模板，但它不起作用

博客模式：

from django.db import models
from django.utils import timezone
from autoslug import AutoSlugField
from category.models import Category


class Post(models.Model):
    author = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    category = models.ForeignKey(Category, on_delete=models.CASCADE,
    default = '')
    title = models.CharField(max_length=200)
    ...

class Meta:
    verbose_name = "Post"
    verbose_name_plural = "Posts"
    ordering = ['created_date']


def publish(self):
    self.published_date = timezone.now()
    self.save()

def __str__(self):
    return self.title

类别模型：

class Category(models.Model):
name = models.CharField(max_length=200)
slug = AutoSlugField(populate_from='name', default='')
parent = models.ForeignKey('self', blank=True, null=True, related_name='children', on_delete=models.CASCADE)
description = models.TextField(max_length=200)

class Meta:
    unique_together = ('slug', 'parent',)    # Enforcing that there can not be two
    verbose_name_plural = "categories"       # categories under a parent with same
                                             # slug

def __str__(self):                           # __str__ method elaborated later in
    full_path = [self.name]                  # post.  use __unicode__ in place of
                                             # __str__ if you are using python 2
    k = self.parent

    while k is not None:
        full_path.append(k.name)
        k = k.parent

    return ' -> '.join(full_path[::-1])

博客浏览：

def post_list(request):
posts = Post.objects.all()
cat_blog = Category.objects.get(pk=1)
context = {
    'posts': posts,
    'cat_blog': cat_blog
}
return render(request, 'blog/post_list.html', context)

类别视图：

def cat_blog(request):
   cat_blog = Category.objects.get(pk=1)
   return render(request, 'blog/post_list.html', {'cat_blog': cat_blog})

post_list.html：

{cat_blog%中类别的%s}
{{category.name}
{{category.description}
{%endfor%}
{posts%%中的post为%s}
//这部分很好
{%endfor%}

post循环很好。如何才能在我的分区标题中获取类别名称和描述？

一个URL提供一个视图提供一个模板

可以使用视图为要渲染的模板提供上下文

def post_list(request):
    posts = Post.objects.all()
    cat_blog = Category.objects.get(pk=1)
    context = {
        'posts': posts,
        'cat_blog': cat_blog
    }
    return render(request, 'blog/post_list.html', context)

您的url.py文件应指向post_列表视图。

同一url不能有两个视图。您应该在一个视图中显示您最初尝试的内容。

def post_list(request):
    posts = Post.objects.all()
    cat_blog = Category.objects.get(pk=1)
    context = {
        'posts': posts,
        'cat_blog': cat_blog
    }
    return render(request, 'blog/post_list.html', context)
