'dict' object has no attribute 'filter' in django

I have created a class based view 

class MyLibrary(generic.DetailView):

    context_object_name = 'data'

    def get_template_names(self):
        request = self.request
        template_name = 'my_library.html'
        return [template_name]

    def get_queryset(self):
        request = self.request
        user = request.user
        context = {}
        mainData = []
        userIssuedBooks = BooksIssued.objects.filter(user=user)
        print(userIssuedBooks)
        if user.is_authenticated():
            context['issuedBooks'] = userIssuedBooks
        return context

I am getting following error when the view is getting called

Internal Server Error: /mylibrary/1/admin

File "C:\Python34\lib\site-packages\django\views\generic\detail.py", line 38,
in get_object
queryset = queryset.filter(pk=pk)
AttributeError: 'dict' object has no attribute 'filter'

I have no clue why this error is getting generated. Can someone help to find what is wrong here?

In django DetailView, get_queryset expects user to return a queryset(as the name implies) but you returned a dict context. You need to do your current stuff in get_context_data instead.

Django doc about adding extra context.
