我正在使用django-haystack并想要覆盖build_page()功能。这是build_page()的 url 。我想paginator用django-paginator. 多谢 ：-）

def build_page(self):
    """
    Paginates the results appropriately.

    In case someone does not want to use Django's built-in pagination, it
    should be a simple matter to override this method to do what they would
    like.
    """

我写了乱七八糟的代码。你能帮帮我吗？谢谢

class MyView(SearchView):
  def build_page(self):
    build_page = super(MyView, self).build_page()
    page = self.results
    return page

我django-haystack与django-pure-pagination. 要使分页工作，您所要做的就是覆盖build_pageHaystacksSearchView类和对象中render的方法。Page

网址.py

from core.views import ModifiedSearchView

urlpatterns = patterns('',
    url(r'^search/', ModifiedSearchView(), name='haystack_search'),
)

视图.py

from haystack.views import SearchView
from pure_pagination.paginator import Paginator
from django.http import Http404

class ModifiedSearchView(SearchView):
    def build_page(self):
        try:
            page_no = int(self.request.GET.get('page', 1))
        except (TypeError, ValueError):
            raise Http404("Not a valid number for page.")

        if page_no < 1:
            raise Http404("Pages should be 1 or greater.")

        paginator = Paginator(self.results, self.results_per_page, request=self.request)
        page = paginator.page(page_no)

        return (paginator, page)

搜索.html

{{ page.render }}

或者

{% include "pagination.html" with page_obj=page %}

分页.html

要修改默认渲染（例如，如果您使用引导程序），最简单的方法是将包pagination.html捆绑的模板复制django-pure-pagination到您的模板目录并包含pagination.html如上所示。

我使用 django-pure-pagination 完成了这项工作

网址.py

from haystack.views import SearchView, search_view_factory
from haystack.forms import SearchForm
from myproj.myapp.views import CustomSearchView

urlpatterns += patterns('haystack.views',
    url(r'^buscar/$', search_view_factory(
        view_class=CustomSearchView,
        template='myapp/obj_list.html',
        form_class=SearchForm
    ), name='haystack_search'),
)

视图.py

from haystack.views import SearchView
from pure_pagination import Paginator, EmptyPage, PageNotAnInteger
from django.conf import settings


class CustomSearchView(SearchView):
    def __name__(self):
        return "CustomSearchView"

    def extra_context(self):
        extra = super(CustomSearchView, self).extra_context()

        try:
            page = self.request.GET.get('page', 1)
        except PageNotAnInteger:
            page = 1

        RESULTS_PER_PAGE = getattr(settings, 'HAYSTACK_SEARCH_RESULTS_PER_PAGE', 20)
        p = Paginator(self.results, RESULTS_PER_PAGE, request=self.request)
        pag = p.page(page)
        extra['page_obj'] = pag

        # important, to make haystack results compatible with my other templates
        extra['myobj_list'] = [i.object for i in pag.object_list]

       return extra
