Django 指定用户角色时呈现或重定向

我正在使用django构建应用程序（请注意，我对django非常陌生）。我想从此现有视图添加重定向

视图中的对象：

from core.views import generic

class ListViewPublic(generic.ListView):
    pass

class BookListView(ListViewPublic):
    model = Book

    def get_queryset(self):
        filter_kwargs = {
            'status': Book.STATUS.public,
        }
        return Book.objects.filter(**filter_kwargs)

    def get_context_data(self, **kwargs):
        context = super(BookListView, self).get_context_data(**kwargs)
        form = SearchForm(load_all=True)
        context.update({'form': form})
        return context

e、 g

• 如果用户未登录，则应显示该页面
• 如果用户的角色为阅读器，则应呈现页面
• 如果用户的角色是作者，则应将其重定向到url

如何实现这种行为？

您可以使用decorator。为了满足您的定制需求，比如它应该重定向到/author，您必须创建定制装饰器。像这样的

from django.utils.decorators import method_decorator
from django.template import RequestContext, Context
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response, redirect, render

def custom_login_required(f):

    def wrap(request, *args, **kwargs):
        """
           this will check user is logged in , if not it will redirect to login page
        """
        if request.user.is_authenticated() and request.user.user_profile.role=='author':
            return HttpResponseRedirect('/author')
        else:
            return render_to_response('index.html', locals(), context_instance=RequestContext(request))
        return f(request, *args, **kwargs)

    wrap.__doc__ = f.__doc__
    wrap.__name__ = f.__name__
    return wrap

@method_decorator(custom_login_required)
def get_context_data(self, **kwargs):
        context = super(BookListView, self).get_context_data(**kwargs)
        form = SearchForm(load_all=True)
        context.update({'form': form})
        return context

上面写着，获取上下文数据，比如这样

from django.utils.decorators import method_decorator
from django.template import RequestContext, Context
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response, redirect, render

def custom_login_required(f):

    def wrap(request, *args, **kwargs):
        """
           this will check user is logged in , if not it will redirect to login page
        """
        if request.user.is_authenticated() and request.user.user_profile.role=='author':
            return HttpResponseRedirect('/author')
        else:
            return render_to_response('index.html', locals(), context_instance=RequestContext(request))
        return f(request, *args, **kwargs)

    wrap.__doc__ = f.__doc__
    wrap.__name__ = f.__name__
    return wrap

@method_decorator(custom_login_required)
def get_context_data(self, **kwargs):
        context = super(BookListView, self).get_context_data(**kwargs)
        form = SearchForm(load_all=True)
        context.update({'form': form})
        return context

嗨@Pawan谢谢你的访问和回答。我在文件顶部添加了

custom\u login\u required

，然后将

@method\u decorator

放在

get\u context\u data

上方，但我得到了错误

wrap（）至少接受一个参数（给定0）

。有线索吗？
