15. 项目实战后台之订单处理

(1). 后台订单处理说明：

后台订单处理模块：浏览订单（搜索&分页）、查看订单详情、订单处理（确认发货，撤销订单）等处理操作。

(2). 项目urls路由信息配置

打开根路由文件：myobject/myadmin/urls.py路由文件，编辑路由配置信息:


from django.conf.urls import url

from myadmin.views import index,users,type,goods,orders

urlpatterns = [
    ...

    # 订单信息管理路由
    url(r'^orders$', orders.index, name="myadmin_orders_index"),
    url(r'^orders/(?P<pIndex>[0-9]+)$', orders.index, name="myadmin_orders_index"),
    url(r'^orders/detail/(?P<oid>[0-9]+)$', orders.detail, name="myadmin_orders_detail"),
    url(r'^orders/state$',orders.state, name="myadmin_orders_state"),
]

　(3).　编辑视图文件

新建视图文件：myobject/myadmin/views/orders.py 视图文件，并进行编辑

from django.shortcuts import render
from django.http import HttpResponse
from django.db.models import Q
from django.core.paginator import Paginator

from common.models import Goods,Users,Orders,Detail

# Create your views here.
def index(request,pIndex=1):
    '''浏览信息'''
    #获取订单信息
    mod = Orders.objects
    mywhere=[]

    # 获取、判断并封装关keyword键搜索
    kw = request.GET.get("keyword",None)
    if kw:
        # 查询收件人和地址中只要含有关键字的都可以
        list = mod.filter(Q(linkman_contains=kw) | Q(address__contains=kw))
        mywhere.append("keyword="+kw)
    else:
        list = mod.filter()

    # 获取、判断并封装订单状态state搜索条件
    state = request.GET.get('state','')
    if state != '':
        list = list.filter(state=state)
        mywhere.append("state="+state)

    #执行分页处理
    pIndex = int(pIndex)
    page = Paginator(list,5) #以5条每页创建分页对象
    maxpages = page.num_pages #最大页数
    #判断页数是否越界
    if pIndex > maxpages:
        pIndex = maxpages
    if pIndex < 1:
        pIndex = 1
    list2 = page.page(pIndex) #当前页数据
    plist = page.page_range   #页码数列表

    # 遍历订单信息并追加 下订单人姓名信息
    for od in list2:
        user = Users.objects.only('name').get(id=od.uid)
        od.name = user.name

    #封装信息加载模板输出
    context = {"orderslist":list2,'plist':plist,'pIndex':pIndex,'maxpages':maxpages,'mywhere':mywhere}
    return render(request,"myadmin/orders/index.html",context)

def detail(request,oid):
    ''' 订单详情信息 '''
    try:
        # 加载订单信息
        orders = Orders.objects.get(id=oid)
        if orders != None:
            user = Users.objects.only('name').get(id=orders.uid)
            orders.name = user.name

        # 加载订单详情
        dlist = Detail.objects.filter(orderid=oid)
        # 遍历每个商品详情，从Goods中获取对应的图片
        for og in dlist:
            og.picname = Goods.objects.only('picname').get(id=og.goodsid).picname

        # 放置模板变量，加载模板并输出
        context = {'orders':orders,'detaillist':dlist}
        return render(request,"myadmin/orders/detail.html",context)
    except Exception as err:
        print(err)
        context = {'info':'没有找到要修改的信息！'}
    return render(request,"myadmin/info.html",context)


def state(request):
    ''' 修改订单状态 '''
    try:
        oid = request.GET.get("oid",'0')
        ob = Orders.objects.get(id=oid)
        ob.state = request.GET['state']
        ob.save()
        context = {'info':'修改成功！'}
    except Exception as err:
        print(err)
        context = {'info':'修改失败！'}
    return render(request,"myadmin/info.html",context)

(4). 编写模板文件

4.1. 订单信息浏览显示模板：/templates/myadmin/orders/index.html。

{% extends "myadmin/base.html" %}

{% block mainbody %}                
    <h4>
        订单信息管理
    </h4>
    <form class="form-inline" action="{% url 'myadmin_orders_index'%}" method="get">
      <label>关键字：</label>
      <input type="text" name="keyword" value="{{request.GET.keyword}}" class="input-small" placeholder="收货人或地址"/>
      <label> &nbsp; 状态：</label>
      <select name="state" class="span1" style="width:100px;">
          <option value="">全部</option>
          <option value="1" {% if request.GET.state == '0' %}selected{% endif %}>未发货</option>
          <option value="1" {% if request.GET.state == '1' %}selected{% endif %}>已发货</option>
          <option value="2" {% if request.GET.state == '2' %}selected{% endif %}>已完成</option>
          <option value="3" {% if request.GET.state == '3' %}selected{% endif %}>已作废</option>
      </select>
      <button type="submit" class="btn">搜索</button>
      <a href="{% url 'myadmin_goods_index' 1 %}" class="btn">全部</a>
    </form>
    <table class="table table-bordered table-striped">
        <thead>
            <tr>
                <th>订单号</th>
                <th>下单人</th>
                <th>收货人</th>
                <th>收货地址</th>

                <th>操作</th>
            </tr>
        </thead>
        <tbody>
            {% for vo in orderslist %}
            <tr>
                <td>{{ vo.id }}</td>
                <td>{{ vo.name }}</td>
                <td>{{ vo.linkman }}</td>
                <td>{{ vo.address }}</td>
                <td>{{ vo.phone }}</td>
                <td>{{ vo.addtime|date:'Y-m-d H:i:s' }}</td>
                <td>
                    {% if vo.state == 0 %}
                        新订单
                    {% elif vo.state == 1 %}
                        已发货
                    {% elif vo.state == 2 %}
                        已完成
                    {% elif vo.state == 3 %}
                        无效订单
                    {% else %}
                        未知
                    {% endif %}</td>
                <td>
                    <a href="{% url 'myadmin_orders_detail' vo.id %}" class="view-link">查看详情</a>
                </td>
            </tr>
            {% endfor %}
        </tbody>
    </table>                
    <div class="pagination">
        <ul>
            <li>
                <a href="{% url 'myadmin_orders_index' pIndex|add:-1 %}?{{ mywhere|join:'&' }}">&laquo;</a>
            </li>
            {% for p in plist %}
            <li {% if pIndex == p %}class="active"{% endif %}>
                <a href="{% url 'myadmin_orders_index' p %}?{{ mywhere|join:'&' }}">{{p}}</a>
            </li>

            </li>

        </ul>
    </div>
{% endblock %}

4.2. 订单详情信息显示模板：/templates/myadmin/orders/detail.html。

{% extends "myadmin/base.html" %}

{% block mainbody %}                
    <h4>
