最近因為在做分頁時遇到的問題很多，頁浪費了好多時間，所以記錄一下。以後如遇到可用省去不必要的麻煩

restframwork中的官方文檔對分頁和搜索頁進行了詳細的介紹，但是我公司需要的return的json數據格式進行分層。所以吧，一個很簡單的東西，搞的頭皮發嘛，看源碼之類的，費時，重點是看不太懂，但最後還是參考源碼，重寫了response方法。

直接上代碼了

url(r‘^show_workPublished‘,views.Show_workPublishedView.as_view(),name=‘show_workPublished‘),

serializer.py

class
 
 Show_workPublishedModelSerialiazer(serializers.ModelSerializer):

    class Meta:
        model = Upload_filep
        #fields = ("id","name","title","img")
        fields = ["id","name","title","img",‘address‘,‘add_time‘]

自定義分頁pagination.py

from rest_framework.pagination import PageNumberPagination

 
class PNPageination(PageNumberPagination):
    page_size = 6  # 每頁顯示2條
    page_query_param = ‘currentPage‘  # 當前頁
    page_size_query_param = ‘page_size‘  # 每頁顯示

view.py

class Show_workPublishedView(generics.ListAPIView):
    queryset = Upload_filep.objects.all().order_by(‘id‘).reverse()
    pagination_class 
 
= PNPageination
    serializer_class = Show_workPublishedModelSerialiazer

    #模糊搜索
    def get_queryset(self):
        name = self.request.GET.get(‘keyword‘)
        if name is not None:
            return self.queryset.filter(Q(name__icontains=name) | Q(title__icontains=name))
        return self.queryset

    def get(self,request,*args,**kwargs):
        list = self.get_queryset()
        #list = Upload_filep.objects.all()
        list_nums = list.count()
        try:
            page = request.GET.get(‘currentPage‘,1)
        except PageNotAnInteger:
            page = 1
        limit = int(request.GET.get(‘limit‘,6))

        p = Paginator(list,limit)
        lists = p.page(page)

        #lists_serializer = Show_workPublishedModelSerialiazer(lists,many=True)
        lists_serializer = self.get_serializer(lists,many=True)

        ret = {
                   "result": True,
                   "msg": "successful",
                   "secure": False,
                   "returnCode": "200",

                   "data": {
                         "list":{
                             "listData":lists_serializer.data,

                             "page_size":limit,                 #每頁顯示兩個
                             "totalCount":list_nums ,           # 一共有多少數據
                             "totalPage": (list_nums//limit if list_nums%limit==0 else list_nums//limit+1) ,   # 一共有多少頁    a-b if a>b else a+b
                             "currentPage": page ,               # 當前頁數
                         },
                   },
              }
        return Response(ret)

到這裏就能搞定分頁和搜索。restframwork分裝的比較多，但有的東西還是得參考源碼重寫方法。
