7.django之自定义分页记录

只是大概记录下步骤：

1.表结构：

class UserProfile(models.Model):
'''
用户表
'''
user = models.OneToOneField(User,verbose_name='后台用户')
#名字
name = models.CharField(max_length=32,verbose_name='姓名')
#头像
head_img = models.ImageField(blank=True,null=True,upload_to="uploads/portrait",verbose_name='头像')
#邮箱
email = models.EmailField(max_length=64,blank=True,null=True,verbose_name='邮箱')
#手机号
phone = models.CharField(verbose_name='手机号',max_length=128)
#部门
department = models.ForeignKey('Group',verbose_name='部门',null=True,blank=True)
#公司ip
ip = models.GenericIPAddressField(max_length=32,verbose_name='办公IP')
#秘钥
secret_key = models.TextField(verbose_name='密钥')
#备注
memo = models.TextField(verbose_name='备注', null=True, blank=True)
#创建时间
create_date  = models.DateField(verbose_name='注册时间',auto_now=True)
def __str__(self):
    return self.name
class Meta:
    verbose_name = '成员'
    verbose_name_plural = '成员'

2.views里函数

#导入分页相关模块
from django.core.paginator import  Paginator,EmptyPage,PageNotAnInteger
def user(request):
    group = models.Group.objects.all()
	#导入user表
    userlist = models.UserProfile.objects.all()
    #设置要显示的页面数量
    paginator = Paginator(userlist,10)
    page = request.GET.get('page')
    try:
        userlist_objs = paginator.page(page)
        print(userlist_objs)
    except PageNotAnInteger:
        #如果页面不是一个整数,交付第一页。
        userlist_objs = paginator.page(1)
    except EmptyPage:
        userlist_objs = paginator.page(paginator.num_pages)
    return render(request,'member/user.html',
	{'userlist_objs':userlist_objs,'group':group})
	#将被分页模块处理过的导入模板中

3.template里

导入分页处理的自定义标签
{% load memtags %}
用户信息
<tbody>
{% for user in userlist_objs %}
<tr class="gradeX">
    <td class="text-center" name="id" value="{{ user.id }}" data-editable='false'>
        <input name="id" value="{{ user.id }}" type="checkbox" class="i-checks">
    </td>
    <td class="text-center hostname"> <a href="{% url 'userdetail' user.id %}">{{ user.name }}</a></td>
    <td class="text-center">{{ user.department }}</td>
    <td class="text-center">{{ user.ip }}</td>
    <td class="text-center">{{ user.phone }}</td>
    <td class="text-center" data-editable='false'>
        <a value="#" class="conn btn btn-xs btn-warning">分发</a>
        <a href="{% url 'userdetail' user.id %}" class="btn btn-xs btn-info">详细资料</a>
    </td>
</tr>
{% endfor %}
</tbody>

分页点击

<div class="col-sm-6">
<div class="dataTables_paginate paging_simple_numbers" id="editable_paginate">
    <ul class="pagination" style="margin-top: 0; float: right">
    {% if userlist_objs.has_previous %}
            <li class="paginate_button previous disabled" aria-controls="editable" tabindex="0" id="editable_previous">
                 <a class="?page={{ userlist_objs.previous_page_number }}" href="#">Previous</a>
            </li>
    {% endif %}
     {% for page_num in userlist_objs.paginator.page_range %}
        {% gusee_page userlist_objs.number page_num %}
    {% endfor %}
    {% if userlist_objs.has_next %}
            <li class="paginate_button next disabled" aria-controls="editable" tabindex="0" id="editable_next">
                <a class="page" href="#">Next</a>
            </li>
            {% endif %}

    </ul>
</div>
</div>

4.自定义标签方法

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from django import template
from django.utils.html import format_html
from django.template.defaultfilters import stringfilter
from django.utils.encoding import force_text
from django.utils.safestring import mark_safe

register = template.Library()

@register.simple_tag
def gusee_page(current_page,loop_num):
    offset = abs(current_page - loop_num)
    if offset <5:
        if current_page == loop_num:
            page_ele = ''' <li class="paginate_button active"  aria-controls="editable" tabindex="0"><a class="page" href="?page=%s"  title="第%s页">%s</a></li>'''%(loop_num,loop_num,loop_num)
        else:
            page_ele = ''' <li class="paginate_button"  aria-controls="editable" tabindex="0"><a class="page" href="?page=%s"  title="第%s页">%s</a></li>'''%(loop_num,loop_num,loop_num)

        return format_html(page_ele)
    else:
        return ''
