retrieve object from previous page


I would like to retrieve my variable ‘foods’ from my result_search function to use it in my saved_substitute function but I can’t find the solution …

def result_search(request):
query = request.GET.get('query')
foods = Food.objects.filter(food__icontains=query)
if foods.count() <= 0:
    return render(request, 'off/result_search.html', {
        'nofoods': "Aucun aliment trouvé !",
    return render(request, 'off/result_search.html', {
        'foods' : foods,

def saved_substitute(request):
    substitute_food = request.GET.get('saved_substitute')
    substitute_food = Food.objects.get(pk=substitute_food)
    create_substitute_saved = Substitute.objects.create(user=request.user, food=substitute_food, substitut=substitute_food)
    user = Substitute.objects.filter(user=request.user)
    paginator = Paginator(user, 5)
    page = request.GET.get('page')
    paginator_user = paginator.get_page(page), 'Votre aliment substitué a été sauvegardé !')
    return render(request, 'off/substitute_saved.html', {
        'user' : paginator_user,

My second problem is that my paginator does not work after page two it returns this error to me(function saved_substitute right up and my temps right down):

{% endfor %}
  <div class="pagination">
<span class="step-links" style="margin: 0 auto;">
    {% if user.has_previous %}
        <a href="?page=1">&laquo; Début</a>
        <a href="?page={{ user.previous_page_number }}">Précédent</a>
    {% endif %}

    <span class="current">
        Page {{ user.number }} sur {{ user.paginator.num_pages }}.

    {% if user.has_next %}
        <a href="?page={{ user.next_page_number }}">Suivant</a>
        <a href="?page={{ user.paginator.num_pages }}">Fin &raquo;</a>
    {% endif %}
{% endif %}

Thanks for your help !

Hi! How are you passing the saved_substitute to the view? since you are using a get request you could either use a form or a url parameter ?saved_substitute=5 which of them are you using?

Did you foregt to include a stack trace?
