Miscellaneous things. Mostly Weeknotes and links I stumbled upon.
Decided to join this years pycon/pydata conference in Karlsruhe. Since this was my home town for a long time, I'm looking forward to meet friends and family. The conference schedule is filled with data science talks, so it should be quite interessting for me :).
The train is quite empty, so maybe I'll be able to work on some blog stuff til Karlsruhe:
Thought it would be nice to have multiple images in an entry. But then they should not all be shown in full size. So I misused the modal component of bootstrap for that. Still have to figure out how to make landscape images wider and portrait pictures smaller, but it's a start.
Here are three images from the pyddf meeting of last week:
Implementing pagination was also quite easy. Since I'm using class based views, I only had to add the attribute paginated_by = 5 to my view class and this snippet to my blogpost_list.html template:
{% verbatim %}
<nav aria-label="pagination">
<ul class="pagination">
{% if page_obj.has_previous %}
<li class="page-item"><a class="page-link" href="?page={{ page_obj.previous_page_number }}">previous</a><li>
{% endif %}
{% if page_obj.has_next %}
<li class="page-item"><a class="page-link" href="?page={{ page_obj.next_page_number }}">next</a></li>
{% endif %}
</ul>
</nav>
Now I added very basic video support:
Added rss feeds for blogs. This was a lot easier than expected since django has a syndication framework already built in. This is the complete code I had to add:
from django.shortcuts import get_object_or_404
from django.core.urlresolvers import reverse
from django.contrib.syndication.views import Feed
class LatestEntriesFeed(Feed):
def get_object(self, request, *args, **kwargs):
self.object = get_object_or_404(Blog, slug=kwargs['slug'])
def title(self):
return self.object.title
def description(self):
return self.object.description
def link(self):
return reverse('blogs:blogpost-feed', kwargs={'slug': self.object.slug})
def items(self):
queryset = BlogPost.objects.filter(blog=self.object).order_by('-created')
return queryset[:5]
def item_title(self, item):
return item.title
def item_description(self, item):
return item.description
url(
regex=r'^(?P<slug>[^/]+)/feed.xml$',
view=views.LatestEntriesFeed(),
name='blogpost-feed'
),
<a href="{% url "blogs:blogpost-feed" slug=blog.slug %}"><img src='/static/images/Feed-icon.svg'></img></a>
