问题有点复杂。 事实上，我并没有试图重新发明轮子，因为后端开发者离开了，我正尽力不要破坏他的代码。
但是，我想这次我需要改变很多东西。或许答案很简单，我的经验之湖与我对抗。
基本上，我有一个文章列表，您可以按类别排序。
我在网址中对这些进行了分类：
urlpatterns = patterns(
'',
url(r'^$', ArticleListView.as_view(), name='articles-list'),
url(r'^source/(?P<source>[\w\.@+-]+)/$', SourceEntriesView.as_view(), name='articles-source'),
url(r'^date/(?P<daterealization>[\w\.@+-]+)/$', DateEntriesView.as_view(), name='articles-date'),
url(r'^country/(?P<region>[\w\.@+-]+)/$', RegionEntriesView.as_view(), name='articles-region'),
url(r'^global/$', GlobalEntriesView.as_view(), name='articles-global'),
)
，主网址为mydomain.com/en/press/
所以基本上，当我尝试按来源对文章进行排序时，例如，我有这个类别的文章显示。但是分页仍然包含所有文章。
所以，如果该类别中只有一篇文章，那么这篇文章只会显示，但是我的＆＃34; loadMore按钮＆＃34;没有被禁用，因为它考虑到有更多的文章背后。
这是主要的views.py基类视图，首先是基数：
class BaseArticleListView(ListView):
"""
Base article list view for manage ajax navigation
"""
model = Article
context_object_name = 'article_list'
template_name = 'base_templates/template_press.html'
paginate_by = get_setting('PAGINATION')
def get_load_more_url(self, request, context):
args = request.GET.copy()
page_obj = context.get('page_obj', None)
if not page_obj or not page_obj.has_next():
return ''
args[self.page_kwarg] = page_obj.next_page_number()
return '?{}'.format(args.urlencode())
def render_to_json_response(self, context, **response_kwargs):
if 'current_app' not in context:
context['current_app'] = resolve(self.request.path).namespace
c = RequestContext(self.request, context)
html_items_list = render_to_string(
'base_templates/template_press.html',
context,
context_instance=c)
html_items_list = html_items_list.strip()
json_response = {
'html_items_list': html_items_list,
'load_more_url': self.get_load_more_url(
self.request,
context)
}
return JsonResponse(json_response)
通用列表条目视图：
#Main article display view
class ArticleListView(FormMixin, BaseArticleView, BaseArticleListView, ContextSourcesMixin):
model = Article
view_url_name = 'djangocms_press:articles-list'
form_class = SourcesRegionsFilterForm
def get_form_kwargs(self):
return {
'initial': self.get_initial(),
'prefix': self.get_prefix(),
'data': self.request.GET or None,
'request': self.request,
}
def get(self, request, *args, **kwargs):
"""
Handle the form submissions to filter by Sources and regions
First_object is use for pagination
"""
context = {}
self.object_list = self.get_queryset().order_by("-date_realization")
first_object = 0
if 'article' in self.request.GET:
try:
project_id = int(request.GET['article'])
context['article_render'] = self.object_list.get(pk=project_id)
except (Article.DoesNotExist, ValueError):
pass
form = self.get_form(self.form_class)
if form.is_valid():
if form.cleaned_data['regions']:
self.object_list = self.object_list.filter(
Q(regions__continent=form.cleaned_data['regions']) | Q(global_regions=True)).distinct()
context.update(self.get_context_data(form=form))
context[self.context_object_name] = context['object_list']
source_qs = ArticleSource.objects.active_translations(get_language()).order_by('translations__name')
date_realization_for_articles = Article.objects.values_list('date_realization',
flat=True).distinct()
region_for_articles = Country.objects.exclude(regions_press_article=None).order_by('name')
context['load_more_url'] = self.get_load_more_url(request, context)
context['dates_realization'] = date_realization_for_articles.dates('date_realization', 'month', order="DESC")
context['sources_list'] = source_qs
context['regions_list'] = region_for_articles
return self.render_to_response(context)
def render_to_json_response(self, context, **response_kwargs):
if 'current_app' not in context:
context['current_app'] = resolve(self.request.path).namespace
c = RequestContext(self.request, context)
html_items_list = render_to_string(
'base_templates/template_press.html',
context,
context_instance=c)
html_items_list = html_items_list.strip()
json_response = {
'html_items_list': html_items_list,
'load_more_url': self.get_load_more_url(self.request, context),
}
return JsonResponse(json_response)
def render_to_response(self, context):
if self.request.is_ajax():
response = self.render_to_json_response(context)
else:
response = super(ArticleListView, self).render_to_response(context)
return response
您可以看到此行更新了loadmore按钮：
context['load_more_url'] = self.get_load_more_url(request, context)
end FINALLY管理已排序源的类：
class SourceEntriesView(ContextSourcesMixin, BaseArticleView, BaseArticleListView):
context_object_name = 'article_list'
template_name = 'base_templates/template_press.html'
_source = None
view_url_name = 'djangocms_press:articles-source'
def get(self, *args, **kwargs):
# submit object to cms toolbar to get correct language switcher behavior
if hasattr(self.request, 'toolbar'):
self.request.toolbar.set_object(self.source)
return super(SourceEntriesView, self).get(*args, **kwargs)
@property
def source(self):
if not self._source:
try:
source_qs = ArticleSource.objects.active_translations(
get_language(),
slug=self.kwargs['source']
)
#source_qs = source_qs.filter(site=Site.objects.get_current().pk)
self._source = source_qs.latest('pk')
except ArticleSource.DoesNotExist:
raise Http404("ArticleSource does not exist for this site")
return self._source
def get_queryset(self):
qs = super(SourceEntriesView, self).get_queryset()
if 'source' in self.kwargs:
qs = qs.filter(sources__pk=self.source.pk)
return qs
def get_context_data(self, **kwargs):
kwargs['source'] = self.source
context = super(SourceEntriesView, self).get_context_data(**kwargs)
return context
因此，当您选择一个源时，最后一个类是从URL调用ajax。但是如何从这里更新加载更多按钮？我迷路了。
在阅读有关分页和基类视图的文档后，我的结论是删除这些行。但我害怕打破一切，而且我无法使其正常运作。
所以，我的问题是更新分页的最佳方式是什么？按某些类别对象进行排序？
提前感谢您，至少在我的请求上花费的时间。
答案 0 :(得分：3)
所以，因为它很复杂（但最终没有）我重写了一切。
现在它正在工作，回到过去的美好时光（再次擦除/编码）。
感谢所有花时间阅读我的请求的人，即使不幸的是没有人能给出答案！
