Django more than one ListView to an html page - html

Question

I am looking to be able to access both post_list10, and photo_list on my blog.html however I am only able to access one when it is written like this. Does anyone know how to write it so I can access both?
post_list10 = Post.objects.all().order_by("-date")[:10]
photo_list = Photo.objects.all()
urlpatterns = patterns('',
url(r'^$', ListView.as_view(
queryset=post_list10,
template_name="blog.html")),
# FOR SOME REASON WHICHEVER COMES FIRST TAKES PRECEDENT. Cannot do both.
url(r'^$', ListView.as_view(
queryset=photo_list,
template_name="blog.html")))
Also,
when calling the list in my blog.html I can use
{% for post in object_list %}
.....
{% endfor %}
in order to work with the available post objects but how do I know if I'm working with posts or photos if I can access both? Sorry if my wording is unclear, I'm quite new to this.

The way to solve your problem would usually involve writing your own view.
A simple way of doing this is as follows:
in urls.py:
from views import my_view
urlpatterns = patterns('',
url(r'^$', my_view, name="my_blog"),
)
in views.py
from django.shortcuts import render
from django.http import HttpResponse
from django.template import RequestContext, loader
def my_view(request):
"""The view for your blog page"""
post_list10 = Post.objects.all().order_by("-date")[:10]
photo_list = Photo.objects.all()
template = loader.get_template('blog.html')
context = RequestContext(request,{
'post_list': post_list10,
'photo_list': photo_list,
})
return HttpResponse(template.render(context))
The the template in blog.html would be changed to this:
{% for post in post_list %}
.....
{% endfor %}
{% for photo in photo_list %}
.....
{% endfor %}
Another thing I noticed is this comment "# FOR SOME REASON WHICHEVER COMES FIRST TAKES PRECEDENT. Cannot do both.". This is indeed the correct, and desired, behavior. The way the URL matching works is that Django starts at the top of the of the URL patterns and then iterates through. The first regex match that is found for the URL in the request is the one that is used and no further searching takes place. Because you had the same regex ^$ for both only the first one in the urlpatterns would ever be matched. This behavior will happen every time you have a duplicated regex, the second one just never gets used.
Generally speaking the Django documentation is very high quality, so do read that if you get stuck.
