Django Redirect Issue: Why Is the Current URL Being Prefixed Instead of Navigating to the Intended Page?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm saving an album section using a form, and while the section is saved correctly, the redirect after a successful POST is causing a 404 error. The redirect seems to be appending the target page (which is specified as a template name) to the current URL. For example, the final URL ends up like this:

albums/album_section_new/f74cf79c-0dc2-4981-a34b-c174d4e2d6b0/album_sections.html

This isn't what I expected – I intended to redirect the user to a page (showing a list of sections) associated with the album's PK.

Below is the relevant view code:

PYTHON
def album_section_new(request, album_pk):
    form = AlbumSectionForm()
    source = request.session['album_source']
    if request.method == 'POST':
        form = AlbumSectionForm(request.POST, request.FILES)
        if form.is_valid():
            this_album = Album.objects.get(pk=album_pk)
            album_section = form.save(commit=False)
            album_section.album_id = this_album
            album_section.save()
            context = {"pk": album_pk,
                       "source": source,}
            return redirect('album_sections.html', context=context)
    else:
        context = {"form": form,
                   "album_pk": album_pk,
                   "source": source}
        return render(request, 'Albums/album_section_edit.html',
                      context)

I suspect the issue might be due to using a template name in the redirect rather than a URL name or path. Has anyone encountered this before, or can suggest what I'm missing? Thanks!

Django Redirect Issue

You've correctly identified the problem. In Django, the redirect() function doesn't work with template names - it works with either:

A URL pattern name (from your urls.py)
A full URL path
A model instance (which uses get_absolute_url())

The Issue

This line is causing your problem:

PYTHON
return redirect('album_sections.html', context=context)

The redirect() function is interpreting 'album_sections.html' as a relative URL and appending it to your current URL, which is why you're getting:
albums/album_section_new/f74cf79c-0dc2-4981-a34b-c174d4e2d6b0/album_sections.html

Solution

You should use a URL pattern name instead. Assuming you have a URL pattern defined in your urls.py like:

PYTHON
path('albums/<uuid:album_pk>/sections/', views.album_sections, name='album_sections')

You would redirect to it like this:

PYTHON
return redirect('album_sections', album_pk=album_pk)

If you don't have a named URL pattern, you could use a hard-coded path:

PYTHON
return redirect(f'/albums/{album_pk}/sections/')

Also note that the redirect() function doesn't accept a context parameter like render() does. If you need to pass data, you should include it in the URL or use the session.

Corrected Code

PYTHON
def album_section_new(request, album_pk):
    form = AlbumSectionForm()
    source = request.session['album_source']
    if request.method == 'POST':
        form = AlbumSectionForm(request.POST, request.FILES)
        if form.is_valid():
            this_album = Album.objects.get(pk=album_pk)
            album_section = form.save(commit=False)
            album_section.album_id = this_album
            album_section.save()
            # Use a named URL pattern
            return redirect('album_sections', album_pk=album_pk)
            # Or use a hard-coded path
            # return redirect(f'/albums/{album_pk}/sections/')
    else:
        context = {"form": form,
                   "album_pk": album_pk,
                   "source": source}
        return render(request, 'Albums/album_section_edit.html',
                      context)
