Question

这是Django文档中的示例：

def listing(request):
    contact_list = Contacts.objects.all()
    paginator = Paginator(contact_list, 25) # Show 25 contacts per page

    page = request.GET.get('page')
    try:
        contacts = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer, deliver first page.
        contacts = paginator.page(1)
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        contacts = paginator.page(paginator.num_pages)

    return render_to_response('list.html', {"contacts": contacts})

模板：

{% for contact in contacts %}
    {# Each "contact" is a Contact model object. #}
    {{ contact.full_name|upper }}<br />
    ...
{% endfor %}

<div class="pagination">
    <span class="step-links">
        {% if contacts.has_previous %}
            <a href="?page={{ contacts.previous_page_number }}">previous</a>
        {% endif %}

        <span class="current">
            Page {{ contacts.number }} of {{ contacts.paginator.num_pages }}.
        </span>

        {% if contacts.has_next %}
            <a href="?page={{ contacts.next_page_number }}">next</a>
        {% endif %}
    </span>
</div>

此显示例如：

第2页，共3页

如何以这种方式显示它：

previous  1 <b>2</b> 3 Next

当前页面带有html <b>标记。

Answer 1

你可以试试这个：

{% for num in contacts.paginator.page_range %}
  {% ifequal num contacts.number %}
    <span class="current"><b>{{ num }}</b></span>
  {% else %}
    <a href="?page={{ num }}"> {{ num }}</a>
  {% endifequal %} 
{% endfor %}

Answer 2

下面的示例实际上是基于类的视图，但可以正常工作。 CSS是Twitter Bootstrap V3.0.0。

{% if is_paginated %}
  <ul class="pagination">
    {% if page_obj.has_previous %}
      <li><a href="?page={{ page_obj.previous_page_number }}">&laquo;</a></li>
    {% else %}
      <li class="disabled"><a href="#">&laquo;</a></li>
    {% endif %}

    {% for num in page_obj.paginator.page_range %}
      {% ifequal num page_obj.number %}
        <li class="active"><a href="#">{{ num }}<span class="sr-only">(current)</span></a></li>
      {% else %}
        <li><a href="?page={{ num }}">{{ num }}</a></li>
      {% endifequal %}
    {% endfor %}

    {% if page_obj.has_next %}
      <li><a href="?page={{ page_obj.next_page_number }}">&raquo;</a></li>
    {% else %}
      <li class="disabled"><a href="#">&raquo;</a></li>
    {% endif %}
  <ul>
{% endif %}

Answer 3

如果有人需要Bootstap 4 Alpha 5版本的代码。

我也做了两处改动：

我不喜欢重复的网页，因此我将案例/profiles/?page=1更改为简单/profiles/。
我有很多页面，所以我没有显示所有页面。我只展示：当前页面中的第1页，最后页，当前页和+3页，以及每10页页面。

如果你需要没有我修改的Bootstrap 4的所有页面，只需删除不必要的代码部分（所有内容都被注释）。

{% if is_paginated %}
    <nav aria-label="Page navigation">
        <ul class="pagination">
            <!-- << PREVIOUS PART -->
            <!-- << Disable 'Previous' page button if you are at the 1st page -->
            {% if not page_obj.has_previous %}
                <li class="page-item disabled">
                    <a class="page-link" href="#" tabindex="-1" aria-label="Previous">

            <!-- << If you are at the 2nd page,
            'Previous' page button will get '/profiles/' url instead of '/profiles/?page=1' -->
            {% elif page_obj.previous_page_number == 1 %}
                <li class="page-item">
                    <a class="page-link" href="{{ profiles_1st_page_url }}" aria-label="Previous">

                        <!-- For the 1st page we do not use ?page=1 -->
                        {% if num == 1 %}
                            <a class="page-link" href="{{ profiles_1st_page_url }}">{{ num }}</a>

                        {% else %}

                            <!-- Shows every 10th page and the last page -->
                            {% elif num|divisibleby:"10" or num == page_obj.paginator.num_pages %}

                        {% endif %}
                    </li>

            {% endfor %}

这是我的。

{% if page.paginator.num_pages > 1 %}
<nav aria-label="Page navigation">

        {% if page.paginator.num_pages != 1 %}
