Django 内置分页的简单使用

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

picture_list = Picture.objects.all().only("avatar")
# 使用django 自带分页
# contact_list = Contacts.objects.all()
paginator = Paginator(picture_list, 12) # 每一页的数据个数
page = request.GET.get('page')
try:
picture_data = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
picture_data = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
picture_data = paginator.page(paginator.num_pages)
return render(request,"picture.html",{"picture_data":picture_data})

{% for picture in picture_data %}
{# Each "contact" is a Contact model object. #}
<a href="{{ picture.avatar }}"><img src="{{ picture.avatar }}" alt="error" title="原图" height="420px" width="310px"></a>
{% endfor %}<div class="pagination">
<span class="step-links">
{% if picture_data.has_previous %}
<a href="?page=1">首页</a>
<a href="?page={{ picture_data.previous_page_number }}">上一页</a>
{% endif %} {% if picture_data.has_next %}
<a href="?page={{ picture_data.next_page_number }}">下一页</a>
<a href="?page={{ picture_data.paginator.num_pages }}">尾页</a>
{% endif %} <span class="current">
第{{ picture_data.number }}页 ,一共 {{ picture_data.paginator.num_pages }} 页.
</span>
</span>
</div>
