尝试使用 django 分页时出现此错误“TemplateDoesNotExist at /videos/”

Question

尝试在 Django 中使用分页时，我不断收到以下错误消息。我已经尝试过，但似乎无法弄清楚这一点。本来可以不用它，但现代网站需要分页。

TemplateDoesNotExist at /videos/

这就是我的观点。py

from django.shortcuts import render, get_object_or_404

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger


from .models import Video


def index(request):
    page = "video/index.html"
    title = "Video"
    # videos = Video.objects.all()

    videos_list = Video.objects.all()
    paginator = Paginator(videos_list, 25)  # Show 25 contacts per page

    page = request.GET.get('page')
    try:
        videos = paginator.page(page)
    except PageNotAnInteger:

        videos = paginator.page(1)
    except EmptyPage:

        videos = paginator.page(paginator.num_pages)

    context = {
        "videos": videos,
        "title": title,
    }
    return render(request, page, context)

这就是我的视频/索引中的内容

{% block content %}
<div id="content"><h1 style="color: #f5f5f5; margin:0">Video index</h1></div>

{% for r in videos %}

    <div class="index-box">
        <div >
            <img src="{{ r.img }}" style="width:241px; height: 200px">
        </div>
        <a href="{% url 'video:detail' r.slug %}">
            <h5 style="margin-left: 10px ">{{ r.title |truncatechars:15}}</h5>
        </a>
    </div>

{% endfor %}




<div class="pagination">
    <span class="step-links">
        {% if videos.has_previous %}
            <a href="?page={{ videos.previous_page_number }}">previous</a>
        {% endif %}

        <span class="current">
            Page {{ videos.number }} of {{ videos.paginator.num_pages }}.
        </span>

        {% if videos.has_next %}
            <a href="?page={{ videos.next_page_number }}">next</a>
        {% endif %}
    </span>
</div>

{% endblock %}

我的文件结构

video
   |-migrations
   |-static
   |-templates
        |-includes
        |-video
            |-detail.html
            |-index.html

我怎样才能纠正这个问题以使其正常工作？欢迎任何和所有帮助。我试图修改文档中的内容以满足我的需要，但我不知道我哪里出错了。

Answer 1

你声明page 2 次。

def index(request):
    **page = "video/index.html"**
    title = "Video"
    # videos = Video.objects.all()

    videos_list = Video.objects.all()
    paginator = Paginator(videos_list, 25)  # Show 25 contacts per page

    **page = request.GET.get('page')**
    try:

Answer 2

我解决了。

page = "video/index.html"

没有被读取。我不得不将它从顶部移到底部

所以我从这里开始

page = "video/index.html" <------------(not being read)
title = "Video"
# videos = Video.objects.all()

videos_list = Video.objects.all()
paginator = Paginator(videos_list, 25)  # Show 25 contacts per page

page = request.GET.get('page')
try:
    videos = paginator.page(page)
except PageNotAnInteger:

    videos = paginator.page(1)
except EmptyPage:

    videos = paginator.page(paginator.num_pages)

context = {
    "videos": videos,
    "title": title,
}
return render(request, page, context) <-------(page has no value)

到

定义索引（请求）：

title = "Video"
# videos = Video.objects.all()

videos_list = Video.objects.all()
paginator = Paginator(videos_list, 2)  # Show 25 contacts per page

page = request.GET.get('page')
try:
    videos = paginator.page(page)
except PageNotAnInteger:

    videos = paginator.page(1)
except EmptyPage:

    videos = paginator.page(paginator.num_pages)

page = "video/index.html" <------------(being read)
context = {
    "videos": videos,
    "title": title,

}
return render(request, page, context) <------------(page has value)
