Python 重写haystack build_page（）函数

我正在使用

django haystack

并希望覆盖

build\u page（）

函数。这里是的url。我想将默认的django

paginator

替换为

django paginator

。非常感谢：-）

我写了一些乱七八糟的代码。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

我使用django纯分页来完成这项工作

url.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'),
)

from core.views import ModifiedSearchView

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

views.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

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)

我使用了带有

django纯分页的
django haystack
。要使分页工作正常，只需从Haystacks
SearchView
类和
render
对象中重写
build\u page
方法

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'),
)

from core.views import ModifiedSearchView

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

views.py

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

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)

或

pagination.html

要修改默认渲染（例如，如果使用引导），最简单的方法是将
django pure pagination
包附带的
pagination.html
模板复制到模板目录中，并包括
pagination.html
，如上图所示。

我在Haystack 2.0.0上测试了此解决方案，我可以确认它是有效的。谢谢eli。我在Haystack 2.0.0上测试了这个解决方案，我可以确认它是有效的。谢谢你，伊莱。
