模板標籤在主頁上發佈cmsplugin博客條目的列表

Question

我使用的是cmsplugin-blog與Django-cms。我想在主頁上顯示最新的博客條目列表（未與插件掛鉤）。爲此，我創建了一個模板標籤。我可以得到一組條目，但不知道如何呈現其標題。任何人都可以指向正確的方向嗎？

這是代碼。

cmsplugin_blog_tags.py：

17 # blog post widget 
18 @register.inclusion_tag('cmsplugin_blog/entry_list_1_snippet.html', takes_context=True) 
19 def render_entries_widget(context, entry_num): 
20  request = context["request"] 
21  language = get_language_from_request(request) 
22  kw = get_translation_filter_language(Entry, language) 
23  
24  return { 
25   'entries': Entry.published.filter(**kw)[0:entry_num], 
26  } 

entry_list_1_snippet.html：

1 {% load i18n placeholder_tags cmsplugin_blog_tags simple_translation_tags %} 
2 
... 
3 <div id="featposts-widget-2" class="widget featposts"> 
4 <div class="widget-wrap"> 
5  <h3 class="widgettitle"><span><a href="/blog">{% trans "VFOSS Blog" %}</a></span></h3> 
6  <div class="cat-posts-widget textwidget"> 
7 
8  {% for entry in entries|annotate_with_translations %} 
      # line 9 does not work. Probably no request. 
9   {% with entry|get_preferred_translation_from_request:request as title %} 
      # no excerpt showed. 
10   {% with entry.placeholders|choose_placeholder:"blog_excerpt" as excerpt %} 
11

我通過注入名單與templatetag背景下實現這一點，包括其他的HTML渲染列表。

標籤：

# blog post widget 
20 @register.tag 
21 def get_latest_entries(parser, token): 
22 bits = token.contents.split() 
23 if len(bits) != 4: 
24  raise TemplateSyntaxError, "(cmsplugin_blog) get_latest_entries tag takes exactly 3 arguments)" 
25 if bits[2] != 'as': 
26  raise TemplateSyntaxError, "second argument to the get_latest_links tag must be 'as'" 
27 return LatestEntriesNode(bits[1], bits[3]) 
28 
29 class LatestEntriesNode(Node): 
30 def __init__(self, num, varname): 
31  self.num, self.varname = num, varname 
32 
33 def render(self, context): 
34  request = context["request"] 
35  language = get_language_from_request(request) 
36  kw = get_translation_filter_language(Entry, language) 
37  context[self.varname] = Entry.published.filter(**kw)[:self.num] 
38  return '' 

放置標籤應該在哪裏出現在列表：

14 {% block entries_widget %} 
    15 {% get_latest_entries 3 as blog_entries %} 
    16 {% if blog_entries %} 
    17  {% include "cmsplugin_blog/widget_latest_entry_include.html" %} 
    18 {% else %} 
    19  <p>{% trans "No entries" %}</p> 
    20 {% endif %} 
    21 {% endblock %}
