Django分页“找不到页面" [英] Django Pagination "Page not found"
问题描述
我目前在Django分页方面遇到问题.我有9个对象的查询集,并将一个对象分页到页面.所以我总共应该有9页.
I'm currently having issues with my Django pagination. I have a query set of 9 objects and am paginating one object to a page. So I should have 9 pages total.
Paginator显示我有9页,但是当我单击下一页"按钮时,我的URL(总是在最后一页/最后两页)变为: http://127.0.0.1:8000/forum/1?page = 7
Paginator is showing that I have 9 pages, but when I click the "next" page button my (Always on the last/last two pages) my url turns to: http://127.0.0.1:8000/forum/1?page=7
然后我得到一个404页面未找到错误以及无效页面(7):该页面没有结果"
Then I get a 404 page not found error along with "Invalid page (7): That page contains no results"
这是我的班级代码:
class DirectoryClass(generic.ListView):
template_name = "forum_directory.html"
model = Directory
paginate_by = 1
def get_context_data(self, **kwargs):
context = super(DirectoryClass, self).get_context_data(**kwargs)
directory = Directory.objects.filter(pk=self.kwargs['directory_id'])
context['page'] = 'forum'
context['name'] = directory.first().name
context['user'] = self.request.user
topic_set = directory.first().topic_set.all().order_by('-last_post')
print(topic_set.all())
paginator = Paginator(topic_set, self.paginate_by)
page = self.request.GET.get('page')
try:
topic_set = paginator.page(page)
except PageNotAnInteger:
topic_set = paginator.page(1)
except EmptyPage:
topic_set = paginator.page(paginator.num_pages)
context['topics'] = topic_set
context['page'] = page
return context
以下是用于更改页面的HTML:
Here is the HTML used to change the page:
<div style="width: 1240px; margin: auto; text-align: right;">
{% if topics.has_other_pages %}
<ul class="pagination forum-pagination">
{% if topics.has_previous %}
<li><a href="?page={{ topics.previous_page_number }}">«</a></li>
{% else %}
<li class="disabled"><span>«</span></li>
{% endif %}
{% for i in topics.paginator.page_range %}
{% if topics.number == i %}
<li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li>
{% else %}
<li><a href="?page={{ i }}">{{ i }}</a></li>
{% endif %}
{% endfor %}
{% if topics.has_next %}
<li><a href="?page={{ topics.next_page_number }}">»</a></li>
{% else %}
<li class="disabled"><span>»</span></li>
{% endif %}
</ul>
{% endif %}
</div>
这是网址
path(r'/<int:directory_id>',views.DirectoryClass.as_view(), name='forum_directory'),
我在做什么错了?
推荐答案
def get_context_data(self, **kwargs):
context = super(DirectoryClass, self).get_context_data(**kwargs)
context['page'] = 'forum'
context['user'] = self.request.user
return context
def get_queryset(self):
directory = Directory.objects.filter(pk=self.kwargs['directory_id'])
topics = directory.first().topic_set.all().order_by('-last_post')
return topics
仅在您的ListView中使用此功能,因为Django为所有基于类的视图提供了分页功能
use this only in your ListView, as Django provides pagination to all the Class Based View
