args and kwargs not passed in BaseDetailView

[Murray Pearson]

In django.views.generic.detail.BaseDetailView's get() method, the arguments and keyword arguments are not passed through for SingleObjectMixin to locate the object. This snippet, from line 110 on, repairs the issue:

class BaseDetailView(SingleObjectMixin, View):
    """
    A base view for displaying a single object
    """
    def get(self, request, *args, **kwargs):
        ### BUG: args and kwargs are not being stored!
        self.args = args # Added 8/21/2016 by MJP
        self.kwargs = kwargs # Added 8/21/2016 by MJP
        self.object = self.get_object()
        context = self.get_context_data(object=self.object)
        return self.render_to_response(context)

The self.args line is probably redundant; I leave it to the developers' judgement whether to include that or not.

Hi Autographic,

I'm not sure I understand your report. While *args and **kwargs are passed to BaseDetailView.get() they are also stored as instance attributes during the ​dispatching phase.

I assume you're hitting this issue because you didn't use the ​as_view() method of your BaseDetailView subclass which takes care of returning the appropriate instance factory.

Is it possible that you created the view instance yourself and either passed the dispatch or get method directly to the url instance (e.g. url(r'^$', BaseDetailViewSubclass().dispatch))?

Please refer to the ​class based view documentation for more details and reopen if you believe this is a Django bug.
