使用Django內建的paginator分頁類別
將原本的Quryset物件(doc_warehouse.objects.all().order_by("id"))丟進Paginator內
他會用你給的limit去切資料
然後將每一頁都指定給Doc_warehouse保持我們原本的templates內的邏輯可以保持不變
doc_info/views.py

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger

def doc_main(request):
    doc_all = doc_warehouse.objects.all().order_by("id")
    limit = 20
    page = request.GET.get('page', 1)
    paginator = Paginator(doc_all, limit)
    try:
        Doc_warehouse = paginator.page(page)  
    except PageNotAnInteger: 
        Doc_warehouse = paginator.page(1) 
    except EmptyPage:  
        Doc_warehouse = paginator.page(paginator.num_pages) 
    context = {
        'Doc_warehouse': Doc_warehouse,
    }
    return render(request, 'doc/main.html', context)
    
@login_required()
def doc_user_list(request):
    user = request.user
    doc_filter = doc_warehouse.objects.filter(user_id=user.id).order_by("id")
    limit = 5
    page = request.GET.get('page', 1)
    paginator = Paginator(doc_filter, limit)
    try:
        Doc_warehouse = paginator.page(page)  
    except PageNotAnInteger: 
        Doc_warehouse = paginator.page(1) 
    except EmptyPage:  
        Doc_warehouse = paginator.page(paginator.num_pages) 
    context = {
        'Doc_warehouse': Doc_warehouse,
    }
    return render(request, 'doc/user_list.html', context)

templates的最下面增加以下
templates/main.html & templates/user_list.html

<p>
{% for page_number in Doc_warehouse.paginator.page_range %}
    {% ifequal page_number  Doc_warehouse.number %}
    {{ page_number }}
    {% else %}
    <a href="?page={{ page_number }}">{{ page_number }}</a>
    {% endifequal %}
{% endfor %}
</p>

效果呈現如下
