How to iterate dictionary objects in template - django

Question

Code
engine.py ==>
class YearGroupCount():
def __init__(self, year, count, months):
self.year = year
self.count = count
self.months = months
class MonthGroupCount():
def __init__(self, month, count):
self.month = month
self.month_name = calendar.month_name[month]
self.count = count
class BlogCountsEngine():
def __init__(self):
self.year_group_counts = {}
def _add_date(self, year, month):
if str(year) in self.year_group_counts:
year_obj = self.year_group_counts[str(year)]
else:
year_obj = YearGroupCount(year, 0, {})
year_obj.count += 1
if str(month) in year_obj.months:
month_obj = year_obj.months[str(month)]
else:
month_obj = MonthGroupCount(month, 0)
month_obj.count += 1
year_obj.months[str(month)] = month_obj
self.year_group_counts[str(year)] = year_obj
def get_calculated_blog_count_list(self):
if not Blog.objects.count():
retval = {}
else:
for blog in Blog.objects.all().order_by('-posted'):
self._add_date(blog.posted.year, blog.posted.month)
retval = self.year_group_counts
return retval
views.py ==>
def outer_cover(request):
archives = BlogCountsEngine().get_calculated_blog_count_list()
retdict = {
'categories': Category.objects.all(),
'posts': posts,
'archives': archives,
}
return render_to_response('blog/blog_list.html', retdict, context_instance=RequestContext(request))
template html ==>
<div class="well">
<h4>Arşivler</h4>
<ul>
{% if archives %}
{% for y_key, yr in archives %}
<li>{{ yr.year }} ({{ yr.count }})</li>
{% for m_key,mth in yr.months %}
<li> - {{ mth.month_name }} ({{ mth.count }})</li>
{% endfor %}
{% endfor %}
{% endif %}
</ul>
</div>
Question:
I am building my own blog with django. I want to iterate in archives to show them in main page but i cannot reach instances' attributes in dictionary
When i run the code over in here the result html is ==>
<div class="well">
<h4>Arşivler</h4>
<ul>
<li> ()</li>
</ul>
</div>
What am i missing or doing wrong?

Answer 1

You can use dict.items method. In python 2.x better use dict.iteritems instead.
{% for y_key, yr in archives.items %}
<li>{{ yr.year }} ({{ yr.count }})</li>
{% for m_key, mth in yr.months.items %}
<li> - {{ mth.month_name }} ({{ mth.count }})</li>
{% endfor %}
{% endfor %}
