Using multiple keyword arguments with reverse()

[Derek]

Hi

I am working with Django 1.11 and Python 3.4.

I am attempting to pass multiple keyword arguments from a reverse() call (from my app called `uploads`).

urls.py

urlpatterns = [

    url(

        regex=r'^add/$',

        view=views.add_new,

        name='add_new'),

    url(

        regex=r'^details/(?P<view>[a-z.]+)/(?P<mid>\d+)?$',

        view=views.upload_details,

        name='upload_details'),

]

views.py

def add_new(request)

    # ... process data via a form; create a result object

    return HttpResponseRedirect(

        reverse('uploads:upload_details',

                kwargs={'view': view, 'mid':result.pk})

    )    

def upload_details(request, view='site', mid=None):

    # ... run process based on view and mid args

When the `upload_details` view gets called, the 'mid' does not set (even though it has a valid integer value); examining the contrib/auth/decorators.py file in debug mode:

    def decorator(view_func):

        @wraps(view_func, assigned=available_attrs(view_func))

        def _wrapped_view(request, *args, **kwargs):

            if test_func(request.user):

                return view_func(request, *args, **kwargs)

shows that the kwargs now only holds:

    {'view': 'site'}

(for reference, the browser address shows: http://127.0.0.1:8000/uploads/details/site/3 )

I am not sure how to pass through both keyword arguments in a way that Django retains and uses them?

Thanks

Derek

try to use url('view function name' x y)

Hi

I am not quite sure what you are suggesting?  Do you think the url() in the urlpatterns should be changed - I have not seen a format like that?

Perhaps you can give an example as it relates to the code I posted.

Thanks

There's no call to reverse in your code. But to do this:

reverse('upload_details', kwargs={'view': 'site', 'mid', 3})

And how is that relevant as well? I think you're missing some code in your
copy, cause this decorator also is not in your view code.

Thanks Melvyn

The call to reverse() *was* included in my original code snippets: see below.

> return HttpResponseRedirect(
>         reverse('uploads:upload_details',
>                 kwargs={'view': view, 'mid':result.pk})

And that call does not work.

def my_view(request):

return redirect('some-view-name', foo='bar')

Ah, totally read over it. But - it *does* work, otherwise upload_details wouldn't get called, since the url would not have a 3 in it.

 

Your problem is somewhere else and I still don't get how the decorator ties in. Try to reduce it to an mcve.
