我一直想知道如何开发一个 django 视图，它支持通过 json 加载对象，并且对于阻塞 js 的客户端，它应该支持非 js 后备 - 使用像 ObjectName.objects.filter() 这样的查询集

对于支持 json 动态数据加载以及不使用 json 获取对象的此类视图，最好的方法是什么？或者只是我的方法是完全错误的，我应该获得更多关于如何编写像http://www.usatoday.com这样的 ajax 动态网站的信息

def index(request):
    q = Page.objects.all()
    return TemplateResponse(request, "orders/order_index.html",
                                {'object_list': q,},)

如果您需要与我的问题相关的任何其他数据，请直接问我。

更新 1 - 示例：

索引呈现您进入网站时看到的初始页面 (example.com)

def index(request):
    q = Entry.objects.all().order_by('-id')
    return TemplateResponse(request, 'index.html', {'object_list': q, })


def detail(request, slug):
    q = get_object_or_404(Entry.objects.all(), slug=slug)
    return TemplateResponse(request, 'blog/templates/blog_detail.html', {'object': q, })

索引.html

{% extends "base.html" %}
{% load webdesign %}
{% load markup %}
{% load humanize %}
{% load endless %}
{% load i18n %}

{% block content %}
    {% paginate object_list %}
    {% for object in object_list %}
        <article>

            <h2>{{ object.title }}</h2>

            <div>

            </div>
            <hr>
            <p>
                {{ object.get_short_text|markdown }}
            </p>

            <div class="clearfix"></div>
            <div class="row">
                <div class="large-6 columns">
                    <span class="metadata"><i class="foundicon-clock"></i> {{ object.date_added|date:"j E Y" }} ({{ object.date_added|naturaltime }})</span>
                </div>
            </div>
            <a class="button expand read_more" href="{{ object.get_absolute_url }}">{% trans "Read more" %}</a>
            <hr>

        </article>
    {% endfor %}
    {% show_pages %}
{% endblock %}

这是一个简单的示例，说明如何利用request.is_ajax()它来返回不同类型的响应：

import json

from django.http import HttpResponse
from django.shortcuts import render


def your_view(request):
    data = {'foo': 'bar'}
    if request.is_ajax():
        return HttpResponse(json.dumps(data), mimetype='application/json')
    else:
        return render(request, 'some-template.html', data)
