is it possible to redirect to another page with id from the previous page?-CodePudding

So as you can see on a page I have Shop name and it's adress. Moreover I have an edit function on views.py:

def update_shop(request, id):
    context = {}

# * fetch the object related to passed id
    obj_shop = get_object_or_404(VideoLibrary, id=id)


# * pass the object as instance in form
    form_shop = VideoLibraryForm(request.POST or None, instance=obj_shop)


# * save the data from the form and
# * redirect to detail_view

    if form_shop.is_valid():
        form_shop.save()
        return HttpResponseRedirect('/main/')

    context['form_shop'] = form_shop

    return render(request, 'update/update_shop.html', context)

urls.py:

...
path('list_view/', views.list_view, name='list_view'),
path('shop/<id>/update', views.update_shop, name='update_shop'),

The image is on a different page ('lilst_view') and the issue is - I need to place a button on this page and redirect to the update page in order to edit certain shop names for example. To do this as I suppose I need to get somehow the id of the object. Does anybody know how to do it?

      {{ data.shop_name }} <br />
      {{ data.adress }} <br />

      {% endfor %}
    </div>
  </body>
</html>

views.py (def list_view):

def list_view(request):

    context = {}

    context['library_dataset'] = VideoLibrary.objects.all()

    return render(request, 'app/list_view.html', context)

in this case you can do it in Django by simply useing redirect() method with parameters, for example

return redirect('some-view-name', parameter_name='par_value')

and in a tag put <a href={% url 'view_name' desired_id %}
