Django分页

如何解决Django分页

我尝试将分页安装到Django应用中。 Django页面在第一页显示前三项，但是当我尝试转到下一页时，第二页什么也没显示。

我希望每页显示3个项目，该怎么办？

这是我的密码。

urls.py

urlpatterns = [
    path('',views.find,name='find'),path('<int:num>',name='find')
]

views.py

def find(request,num=1):
    
    if (request.method == 'POST'):
        msg = request.POST['find']
        form = FindForm(request.POST)
        sql = 'select * from test_eu'
        if (msg != ''):
            sql += " where eng_discription ~ '.*" + msg +".*' ORDER BY image_amount DESC " 
        data =TestEu.objects.raw(sql)
        page = Paginator(data,3)
        msg = sql
    else:
        msg = 'search words...'
        form = FindForm()
        data = ""
        page = Paginator(data,3)
        
    params = {
        'title': 'Search Customs Rulings','message': msg,'form':form,'data': page.get_page(num),}
    return render(request,'db/find.html',params)

find.html

   ......
        <ul class="pagination">
        {% if data.has_prevIoUs %}
        <li class="page-item">
            <a class="page-link" href="{% url 'find' %}">
                &laquo; first</a>
        </li>
        <li class="page-item">
            <a class="page-link" 
            href="{% url 'find' %}{{data.prevIoUs_page_number}}">
                &laquo; prev</a>
        </li>
        {% else %}
        <li class="page-item">
            <a class="page-link">
                &laquo; first</a>
        </li>
        <li class="page-item">
            <a class="page-link">
                &laquo; prev</a>
        </li>
        {% endif %}
        <li class="page-item">
            <a class="page-link">
            {{data.number}}/{{data.paginator.num_pages}}</a>
        </li>
        {% if data.has_next %}
        <li class="page-item">
            <a class="page-link" 
            href="{% url 'find' %}{{data.next_page_number }}">
                next &raquo;</a>
        </li>
        <li class="page-item">
            <a class="page-link" 
            href="{% url 'find' %}{{data.paginator.num_pages}}">
                last &raquo;</a>
        </li>
        {% else %}
        <li class="page-item">
            <a class="page-link">
                next &raquo;</a>
        </li>
        <li class="page-item">
            <a class="page-link">
                last &raquo;</a>
        </li>
        {% endif %}
    </ul>

“ find.html”的代码我省略了前几个代码，因为在此问题中没有必要。
