I’m sure I’m not understanding render() and redirect() correctly, but why does this:

return render(request, 'catalog/add.html', {'form': form}) (where the app name is ‘catalog’)

Produce this url:

http://127.0.0.1:8000/catalog/add/catalog_add

This happens with this function:

def catalog_add(request):
    if request.method == 'POST':
        form = ArtworkForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('catalog')
    else:
        form = ArtworkForm()
    return render(request, 'catalog/add.html', {'form': form})

The GET finds the html page (catalog/add.html) and correctly populates it with an empty form, but the POST results in ‘Page not found… The current path, catalog/add/catalog_add, didn’t match any of these.’

Both render() and redirect() have the same behavior.
