【问题标题】:django-endless with class based views exampledjango-endless 与基于类的视图示例

【问题描述】:

我是第一次使用基于类的视图。我无法理解如何使用基于类的视图来实现 django-endless-pagination twitter 样式分页。

我可以举一个例子来说明如何去做吗?

这是我的看法:

class EntryDetail(DetailView):
    """
    Render a "detail" view of an object.
    By default this is a model instance looked up from `self.queryset`, but the
    view will support display of *any* object by overriding `self.get_object()`.
    """
    context_object_name = 'entry'
    template_name = "blog/entry.html"
    slug_field = 'slug'
    slug_url_kwarg = 'slug'

    def get_object(self, query_set=None):
        """
        Returns the object the view is displaying.

        By default this requires `self.queryset` and a `pk` or `slug` argument
        in the URLconf, but subclasses can override this to return any object.
        """
        slug = self.kwargs.get(self.slug_url_kwarg, None)
        return get_object_or_404(Entry, slug=slug)

【解决方案1】:

由于这是一个广泛的问题,我现在想结合几种分页解决方案。

1.使用通用ListView

from django.views.generic import ListView

class EntryList(ListView):
    model = Entry
    template_name = 'blog/entry_list.html'
    context_object_name = 'entry_list'
    paginate_by = 10

只使用urls.py会更快:

url(r'^entries/$', ListView.as_view(model=Entry, paginate_by=10))

所以基本上你在这个解决方案中不需要 django-endless-pagination。您可以在此处查看模板示例:How do I use pagination with Django class based generic ListViews?

2.使用django-endless-pagination的AjaxListView:

from endless_pagination.views import AjaxListView    
class EntryList(AjaxListView):
    model = Entry
    context_object_name = 'entry_list'
    page_template = 'entry.html'

或仅使用urls.py 更快(再次):

from endless_pagination.views import AjaxListView

url(r'^entries/$', AjaxListView.as_view(model=Entry))

参考:http://django-endless-pagination.readthedocs.org/en/latest/generic_views.html

如果有人知道不同的解决方案,请发表评论。

【讨论】:

  • 我不明白 ListView 示例的paginate_by = 10。 django 文档没有解释这一点。哪个代码应该评估paginate_by = 10
  • ListView 子类MultipleObjectMixin。你可以在这里查看它关于分页的文档:docs.djangoproject.com/en/dev/ref/class-based-views/…
