分页器无法在Django中工作

Question

I've followed the official docs to use paginator in Django and it not working, it shows the right page count but on every page, the whole list displayed instead of slicing it into many pages

views.py

def home(request):
    current_user = request.user
    all_dress = Item.objects.all().filter(dress_active=True).order_by('-created_at')
    all_good = Item.objects.all().filter(dress_special=True)
    all_name = Name.objects.all()
    all_ads = Ads.objects.all()
    #pig
    paginator = Paginator(all_dress, 3) # Show 12 dress per page
    page = request.GET.get('page')
    dresss = paginator.get_page(page)

    context = {
        'all_dress': all_dress,
        'all_name': all_name,
        'current_user': current_user,
        'all_good':all_good,
        'all_ads':all_ads,
        'dresss':dresss,
    }
    return render(request, 'fostan/index.html',context)

HTML

    <div class="row">
    <div class="col">
      &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
      &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    </div>
    <div class="col">
        <div dir="ltr">
     <div class="pagination" align="left">
    <span class="step-links" align="left">
        {% if dresss.has_previous %}
            <a href="?page=1">&laquo; first </a>
            <a href="?page={{ dresss.previous_page_number }}"> previous</a>
        {% endif %}

        <span class="current">
            Page number {{ dresss.number }} of {{ dresss.paginator.num_pages }}
        </span>
<br>
        {% if dresss.has_next %}
            <a href="?page={{ dresss.next_page_number }}">next </a>
            <a href="?page={{ dresss.paginator.num_pages }}">last  &raquo;</a>
        {% endif %}
    </span>
</div>
    </div>
</div>
    <div class="col">
              &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
      &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
        </div>
    </div>

I have 9 items, and I asked the paginator to show only 3 items per page, the result is 3 pages with the same 9 items on every page!

item list

  <ul class="thumbnails" >
      {% for dress in all_dress %}
    <li class="span4 pull-left" >
      <div class="thumbnail">
        <a class="zoomTool" href="{% url 'dress_details' dress.pk%}" title="add to cart"><span class="icon-search"></span> عرض التفاصيل</a>
        <a  href="{% url 'dress_details' dress.pk%}"><img class="main" src="{{ dress.dress_image1.url }}" alt=""></a>
        <div class="caption">
          <h5> فستان  {{ dress.dress_name }} </h5>
          <h4>
              <a class="defaultBtn" href="{% url 'dress_details' dress.pk%}" title="إضفط لمشاهدة الفستان"><span class="icon-zoom-in"></span></a>

              <span class="pull-left">{{ dress.dress_price }} جنيه </span>
          </h4>
        </div>
      </div>
    </li>

      {% endfor %}

  </ul>

Answer 1

You should do this way:

paginator = Paginator(all_dress, 3)
page = request.GET.get('page')

try:
    dresss = paginator.page(page)
except PageNotAnInteger:
    dresss = paginator.page(1)
except EmptyPage:
    dresss = paginator.page(paginator.num_pages)
