Question

我已验证“书籍”表中有条目，但是由于似乎无法查明原因，我的模板未显示它们。

型号：

class Book(models.Model):
    bookTitle = models.CharField(max_length = 100)
    bookURL = models.SlugField() 
    bookContent = models.TextField()
    bookAuthor = models.ForeignKey(User, on_delete = models.CASCADE,  related_name = 'books')
    creationDate = models.DateTimeField()

模板：

{% extends 'base.html' %}

{% block content %}
{% for p in books %}
    <div class="post-wrapper col-lg-8 card" style="border: 1px solid black; margin: 20 auto;">
        <div class="card-body">
            <div class="card-title">{{  p.bookTitle  }}</div>
            <div class="card-body">
                {{  p.bookContent   }}
            </div>
            <em style="margin-left: 10px;"><small>written by {{  p.bookAuthor  }} at {{  p.creationDate  }}</small></em>
        </div>
    </div>
{% endfor %}
{% endblock %}

查看：

from django.shortcuts import render
from django.http import HttpResponse
from .models import Book
from django.utils import timezone

# Create your views here.

def viewAll(request):
    books = Book.objects.all()
    return render(request, 'viewAll.html', {})

Answer 1

您没有将任何数据传递到视图上下文-您需要在上下文字典（第三个参数）中传递books：

def viewAll(request):
    books = Book.objects.all()
    return render(request, 'viewAll.html', {'books': books}) # <--- this is currently empty
