python - 连接模板和 View 分页

Question

我知道，我重复一遍，我是编程世界的新手...但我更喜欢这样说，即使我认为从我的问题中显而易见...:)

这是我的模板:

Fims.html:

这是我的观点:

def films(request):
    films = Film.objects.order_by("anno", "titolo")
    paginator = Paginator( films, 2 )
    try:
        pagina = int( request.GET.get( "pagina", "1" ) )
    except ValueError:
        pagina = 1
    try:
        pagine = paginator.page( pagina )
    except ( EmptyPage, InvalidPage ):
        pagine = paginator.page ( paginator.num_pages )
    return render_to_response('Films.html', { 'films': pagine, 'pagine': range( 1, paginator.num_pages + 1 ) } )

def brani(request):
    brani = Brano.objects.order_by("anno", "titolo")
    paginator = Paginator( brani, 2 )
    try:
        pagina = int( request.GET.get( "pagina", "1" ) )
    except ValueError:
        pagina = 1
    try:
        pagine = paginator.page( pagina )
    except ( EmptyPage, InvalidPage ):
        pagine = paginator.page ( paginator.num_pages )
    return render_to_response('Brani.html', { 'brani': pagine, 'pagine': range( 1, paginator.num_pages + 1 ) } )

我只想有一个模板，因为它们实际上是相同的，我还想创建一个 def Pagination 来调用 def film 和 def brani.

对于 {% block titolo %} 和我想更改的其他单词(如果是电影或brani 不是问题)，我使用 {% iffilms %} 或 {% if brani %}。

但如果我只想要一个，我不知道如何从 View 中的函数传递 'films': pagine 或 'brani': pagine两者的功能分页。有人可以帮助我吗？

Answer 1

您可以使用 1.3 版以来可用的通用 ListView 来减少代码重复

views.py

from django.views.generic.list import ListView

class FilmListView(ListView):
    model = Film
    paginate_by = 10
    page_kwarg = 'pagina'
    context_object_name = "films"

class BranoListView(ListView):
    model = Brano
    paginate_by = 10
    page_kwarg = 'pagina'
    context_object_name = "brani"

然后您可以设置通用分页模板

分页.html

{% extends "base.html" %}

{% block contenuto %}
  {% block pagina %}
  <div class="grid_16 center">
    {% if objects.has_previous %}
      <a class="color2 bold hover" href="?pagina={{ objects.previous_page_number }}">precedente</a>
    {% endif %}

    {% for i in paginator.page_range %}
      {% if i == page.number %}
        <a class="color1 bold line size20">{{ i }}</a>
      {% else %}
        <a class="black bold hover" href="?pagina={{ i }}">{{ i }}</a>
      {% endif %}
    {% endfor %}

    {% if objects.has_next %}
      <a class="color2 bold hover" href="?pagina={{ objects.next_page_number }}">successivo</a>
    {% endif %}
  </div>
  {% block pagina %}
{% endblock %}

电影.html

{% extends "pagination.html" %}

{% block titolo %}Films{% endblock %}

通过这种方式，您可以强制分离，以便在这些 View 的模板中只表示不同 View 之间不同的内容
