Question

我有这个基于类的视图：

class Browse(APIView):
'''
Browse associations

'''
permission_classes = [TokenHasReadWriteScope]

def get(self,request,format=None):
    reply={}
    status=200


    try:
        filter_options={}
        name=request.query_params.get('name','').strip()
        if name:
            filter_options['name__icontains']=name


        associations=Association.objects.filter(**filter_options)values('id','name')
        page=request.query_params.get('page',1)
        paginator=Paginator(associations,20)
        data=paginator.page(page)
    except PageNotAnInteger:
        data=paginator.page(1)
    except EmptyPage:
        data=paginator.page(paginator.num_pages)

    except:
        status=400
        reply['detail']=(_('ErrorProcessingRequest'))

    if status==200:
        reply['associations']=list(data)
        reply['total_num_of_pages']=paginator.num_pages
        reply['total_rows_found']=paginator.count

    return JsonResponse(reply,status=status)

现在我有另一个面向内部用户的应用程序（不同的登录和所有）但我想列出关联仍然。上面的代码很简短，我不介意在那里粘贴它，但只是想知道我是否可以通过调用另一个应用程序的views.py浏览来避免DRY。

目前，我从app 2开始：

      from app1.views import Browse
      b=Browse()
      #but I cant serialize it as it returns <app1.views.Browse object at 0x0000000006CE0E80> is not JSON serializable

Answer 2

使用此导入语句

from appName.views import viewName as variable_Name

稍后致电

return variable_Name(request)

从同一项目中的另一个应用程序调用应用程序的基于类的视图
