怎么在自己的项目里加入 bootstrap 和 jqucry ？

下载下来再拷贝到项目里(jqucry1.0支持IE 8,9的)

前端展示用户列表：

自定义分页（模块化）

把分页写成模块，以后用到分页的时候可以调用：

1、在Django中先生成一个app00，注册，配置url&views

from django.conf.urls import url
from django.contrib import admin
from app00 import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^user_list/',views.user_list),
]

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app00',
]

from django.db import models
class UserProfile(models.Model):
    user = models.OneToOneField(User) #alex
    name = models.CharField(max_length=64)
    school = models.ForeignKey('School')

2、分页代码

from django.shortcuts import render,redirect
import models
from django.core.paginator import Paginator,EmptyPage,PageNotAnInteger
from crm import forms
from  permissions import  check_permission
# Create your views here.

def dashboard(request):
    return render(request,'crm/dashboard.html')


@check_permission
def customers(request):
    customer_list = models.Customer.objects.all()
    paginator = Paginator(customer_list,3)
    page = request.GET.get('page')
    try:
        customer_objs = paginator.page(page)
    except PageNotAnInteger:
        customer_objs = paginator.page(1)
    except EmptyPage:
         customer_objs = paginator.page(paginator.num_pages)
    return render(request,'crm/customers.html',{'customer_list':customer_objs})

@check_permission
def customer_detail(request,customer_id):
    customer_obj = models.Customer.objects.get(id=customer_id)
    if request.method == "POST":#后台判断POST
        form = forms.CustomerModelForm(request.POST,instance=customer_obj)
        #print(request.POST)
        if form.is_valid():#修改之前先作验证
            form.save()
            print( 'url:',request.path)#获取url
            base_url = "/".join(request.path.split("/")[:-2])
            print( 'url:',base_url)
            return redirect(base_url)
        #else:
    else:
        form = forms.CustomerModelForm(instance=customer_obj)
    return render(request,'crm/customer_detail.html',{'customer_form':form})

{% extends 'base.html' %}
{% load custom_tags %}
{% block page-header %}
客户信息列表
{% endblock %}
{% block page-content %}
    <table class="table table-hover">
        <thead>
            <tr>
                <th>ID</th>
                <th>QQ</th>

                <th>日期</th>
            </tr>
        </thead>
        <tbody>
        {% for customer in customer_list %}
        <tr>
            <td><a href="{% url 'customer_detail' customer.id  %}">{{ customer.id }}</a></td>

        {% endfor %}

通用权限系统的设计思路：

 加权限是因为希望不同的角色有不同的权限，不同的角色做的事情是不一样的。
