【问题描述】：

当我在管理面板中添加帖子时，帖子不会显示在应用程序的主页上。 它只显示帖子的空格，但无法在主页上显示帖子的文章。

views.py

from django.shortcuts import render,HttpResponseRedirect
from django.contrib import messages
from django.http import HttpResponse
from .forms import SignUpForm, LoginForm
from django.contrib.auth import authenticate, login, logout
from .models import Post
# Create your views here.

# home
def home(request):
    posts = Post.objects.all()
    return render(request, 'blog/home.html','posts':posts)

home.html

% extends 'blog/base.html' %
% load static %

% block content %

<div class="col-sm-10">
  <h3 class="text-white my-5">Home Page</h3>
    % for post in posts %
      <div class="jumbotron jumbotron-fluid jumbo-colour">
        <div class="container">
          <h1 class="display-4 font-weight-bold">posts.title</h1>
          <p class="lead">posts.desc</p>
        </div>
      </div>
    % endfor %
</div>

% endblock content %

models.py

from django.db import models

# Create your models here.
class Post(models.Model):
    title = models.CharField(max_length=150)
    desc = models.TextField()

【参考方案1】：

您的代码中有错字。应该是：

% for post in posts %
  <div class="jumbotron jumbotron-fluid jumbo-colour">
    <div class="container">
      <h1 class="display-4 font-weight-bold">post.title</h1>  // not posts.title
      <p class="lead">post.desc</p>  // not posts.desc
    </div>
  </div>
% endfor %
