必要に応じてさまざまなモデルで動作できる、より一般的なバージョンの Django クラス ベースの詳細ビューを実装しようとしています。アイデアは、次のように URL のパラメーターを使用してモデルを設定することでした。

url(r'^product/view/(?P<bought_in_control_panel_id>\d+)/(?P<item_uuid>'+uuid_re+'/)',
    GenericModelDetailView().as_view(pk_url_kwarg='item_uuid',
                                     template_name='suppliers/products/view_product.html')
    , name='view_product'),

これは私が使用しているクラスですが、django はオブジェクト属性を持たないクラスについて不平を言っています。

class GenericModelDetailView(DetailView):

    def __init__(self, *args, **kwargs):
        self.model = get_model_for_bought_in_control_panel(super(GenericModelDetailView, self).get_context_data(**kwargs)['bought_in_control_panel_id'])
        super(GenericModelDetailView, self).__init__(**kwargs)

スタックトレース：
