一 登錄頁(yè)面的設(shè)計(jì)

• views中先定義login構(gòu)造登錄上下文

• views中定義login_handle對(duì)登錄傳入的數(shù)據(jù)做處理及設(shè)置cookie值等功能

   views.py
   def login(request):
       uname = request.COOKIES.get('uname','')
       context = {'title':'用戶(hù)登錄','erorr_name':0,'error pwd ':0,'uname':uname}
       return  render(request,'df_user/login.html',context)
  
  
   def login_handle(request):
       # 接收請(qǐng)求信息
       get = request.POST
       uname = get.get('username')
       upwd = get.get('pwd')
       jizhu = get.get('jizhu', 0)
       # 根據(jù)用戶(hù)名查詢(xún)對(duì)象
       users = UserInfo.objects.filter(uname=uname)
       # print uname
       # 判斷如果未查到則用戶(hù)名錯(cuò)，查到再判斷密碼是否正確，正確則轉(zhuǎn)到用戶(hù)中心
       if len(users) == 1:
           s1 = sha1()
           s1.update(upwd.encode('utf8'))
           #登錄帶cookie值   必須 red = HttpResponseRedirect    red.set_cookie  renturn red
           if s1.hexdigest() == users[0].upwd:
               red = HttpResponseRedirect('/user/info')
               # count = CartInfo.objects.filter(user_id=users[0].id).count()
  
               # print '*'*10
               # print count
               # 記住用戶(hù)名
               if jizhu != 0:
                   red.set_cookie('uname', uname)
               else:
                   red.set_cookie('uname', '', max_age=-1)
               request.session['user_id'] = users[0].id
               request.session['user_name'] = uname
               # request.session['count'] = count
               return red
           else:
               context = {'title': '用戶(hù)登錄', 'error_name': 0, 'error_pwd': 1, 'uname': uname}
               return render(request, 'df_user/login.html', context)
       else:
           context = {'title': '用戶(hù)登錄', 'error_name': 1, 'error_pwd': 0, 'uname': uname }
           return render(request, 'df_user/login.html', context)
  

二 設(shè)計(jì)登錄后的用戶(hù)info頁(yè)面

• info的頁(yè)面要顯示郵箱，用戶(hù)姓名，等信息，所以在views中的info構(gòu)造context上下文
• 構(gòu)造用戶(hù)的收貨地址，這里需要用戶(hù)全部信息，save保存后把數(shù)據(jù)進(jìn)行傳輸。
• 設(shè)計(jì)注銷(xiāo)用戶(hù)的功能，這里清除cookie

views.py
def logout(request):
      request.session.flush()
      return redirect('/')
 
def site(request):
    user = UserInfo.objects.get(id=request.session['user_id'])
    if request.method == 'POST':
        post = request.POST
        user.ushou = post.get('ushou')
        user.uaddress = post.get('uaddress')
        user.uphone = post.get('uphone')
        user.uyoubian = post.get('uyoubian')
        user.save()
    context = {'title': '用戶(hù)中心', 'user': user,'page_name':1,'site':1}
    return render(request, 'df_user/user_center_site.html', context)

三設(shè)計(jì)用戶(hù)提交訂單的頁(yè)面

• 此頁(yè)面用戶(hù)展示用戶(hù)提交的訂單，由購(gòu)物車(chē)頁(yè)面下單后轉(zhuǎn)調(diào)過(guò)來(lái)，也可以從個(gè)人信息頁(yè)面查看
• 根據(jù)用戶(hù)訂單是否支付、下單順序進(jìn)行排序

def user_center_order(request, pageid):
    """
    # 此頁(yè)面用戶(hù)展示用戶(hù)提交的訂單，由購(gòu)物車(chē)頁(yè)面下單后轉(zhuǎn)調(diào)過(guò)來(lái)，也可以從個(gè)人信息頁(yè)面查看
    # 根據(jù)用戶(hù)訂單是否支付、下單順序進(jìn)行排序
    # """
    #
    uid = request.session.get('user_id')
    #訂單信息，根據(jù)是否支付、下單順序進(jìn)行排序
    orderinfos = OrderInfo.objects.filter(
        user_id=uid).order_by('zhifu', '-oid')
    #
    # 分頁(yè)
    #獲取orderinfos list  以?xún)蓚€(gè)為一頁(yè)的 list
    paginator = Paginator(orderinfos, 2)
    #獲取 上面集合的第 pageid 個(gè) 值
    orderlist = paginator.page(int(pageid))
    #獲取一共多少 頁(yè)
    plist = paginator.page_range
    #3頁(yè)分頁(yè)顯示
    qian1 = 0
    hou = 0
    hou2 = 0
    qian2 = 0
    # dd = dangqian ye
    dd = int(pageid)
    lenn = len(plist)
    if dd>1:
        qian1 = dd-1
    if dd>=3:
        qian2 = dd-2
    if dd<lenn:
        hou = dd+1
    if dd+2<=lenn:
        hou2 = dd+2
    #
    #
    #
    # 構(gòu)造上下文
    context = {'page_name': 1, 'title': '全部訂單', 'pageid': int(pageid),
               'order': 1, 'orderlist': orderlist, 'plist': plist,
               'pre':qian1,'next':hou,'pree':qian2,'lenn':lenn,'nextt':hou2}

    return render(request, 'df_user/user_center_order.html',context)
