从同一项目中的另一个应用程序调用一个应用程序的基于类的视图 [英] Calling a class-based view of an app from another app in same project

问题描述

我有基于此类的视图:

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(不同的登录名和所有用户名)，但我仍要列出关联.上面的代码很短，我不介意将其粘贴到那里，只是想知道是否可以通过调用另一个应用程序的views.py中的Browse来避免DRY.

Now I have another app that is oriented towards internal users (different login and all) but I want to list the associations still. The above code is short and i don't mind pasting it there but just wondering if I can avoid DRY by calling the Browse from views.py of another app.

当前，我尝试从应用2中进行尝试:

Currently, I trie this from app 2:

      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

推荐答案

按照以下

Solved it following this SO Answer. All I had to do was:

view = Browse.as_view()
return view(request)
