在Django實施每年一次的月度存檔

Question

我在我的網站的單獨頁面上構建了以前的存檔。不過，Django這次似乎不想與我合作。

class IndexView(ArchiveIndexView): 
    template_name = 'cms/blog_base.html' 
    date_field = 'pub_date' 
    latest = '20' 
    model = Entry 

In template {% for year in date_list %} {{ year|date:"Y" }} gives me a date relating to none of my entries. {% for entry in object_list % } {{ entry.pub_date|date:"Y" }} obviously outputs the correct date for the entry but as the entries grow I can only imagine it will continue to duplicate the years and months. 

那麼我做錯了什麼？爲了將日期與我的條目集合關聯起來，我需要在ArchiveIndexView和模板標籤中做些什麼？過去，它們在單獨的頁面上，因此被URL conf中的正則表達式過濾。我看到的一個解決方案是使用一些原始SQL創建自定義管理器，這就是我所看到的？如果是的話，我會重新考慮這一切。預先感謝社區。

更新：例如：我在我的主頁上想要的東西與本頁上的內容類似https://unweb.me/blog/monthly-archives-on-Django我現在也在考慮嘗試他們的解決方案，因爲它看起來像一個不錯的UI/UX。但是，我是一個簡單的人，如果有一個簡單的路線，我會很樂意。

一個更好的解決辦法，我已經從一個簡短的教程博客網上找到實現以下。我驗證它的工作原理。

def mkmonth_lst(): 
"""Make a list of months to show archive links.""" 
if not Post.objects.count(): return [] 

# set up vars 
year, month = time.localtime()[:2] 
first = Post.objects.order_by("created")[0] 
fyear = first.created.year 
fmonth = first.created.month 
months = [] 

# loop over years and months 
for y in range(year, fyear-1, -1): 
    start, end = 12, 0 
    if y == year: start = month 
    if y == fyear: end = fmonth-1 

    for m in range(start, end, -1): 
     months.append((y, m, month_name[m])) 
return months 

def main(request): 
"""Main listing.""" 
posts = Post.objects.all().order_by("-created") 
paginator = Paginator(posts, 10) 
try: page = int(request.GET.get("page", '1')) 
except ValueError: page = 1 

try: 
    posts = paginator.page(page) 
except (InvalidPage, EmptyPage): 
    posts = paginator.page(paginator.num_pages) 

return render_to_response("list.html", dict(posts=posts, user=request.user, 
              post_list=posts.object_list, months=mkmonth_lst())) 

# The template info 
    <div id="sidebar"> 
    Monthly Archive 
    <p> 
    {% for month in months %} 
     {% ifchanged month.0 %} {{ month.0 }} <br /> {% endifchanged %} 
     <a href="{% url blog.views.month month.0 month.1 %}">{{ month.2 }}</a> <br /> 
    {% endfor %} 
    </p> 
</div> 

這將在您的主頁上生成一個年份分隔列表，其中僅包含帖子的月份。

您是否在尋找regroup -feature？

例子：

{% regroup object_list by date_field|date:"Y" as year_list %} 
{% for year in year_list %} 
    {% regroup year.list by date_field|date:"F" as month_list %} 
    {% for month in month_list %} 
     {{ month.grouper }}/{{ year.grouper }} <br /> 
     {{ month.list }} 
    {% endfor %} 
{% endfor %}
