Hi.
Since you do have show post url, I would create random view just to
redirect to show post view with random post id.

Hi,
You can use MongoDB with Django just fine. Though, you won't get any ORM
integration.
If you're not bound to MongoDB yet personally I would suggest to take a
look at ArangoDB. It doesn't have ORM integration either but in my opinion
it's much better than MongoDB. It has many SQL-like features
Hi,
I'm not sure is there already such expression/aggregation available, but
you can always create your own expression/aggregate that does whatever you
want to.
Check Django sources to check how GIS lookups/aggregates are made.

Hi,
I didn't realize what you were asking for. :D
Django has bunch of spatial queries, so you're looking some of those
__inside, __within lookups. Coordinate transformations do happen
automatically so you just need to provide srid for you "envelope".

Something like following should work. Didn't checked if that actually works.
Mymodel.objects.filter(geom__inside=Polygon.from_bbox((x1,y1,x2,y2),
srid=1234))

Hi,
My recommendation is to check out libschevo. [1]
It is compatible with Durus and ZODB databases and support schema
migrations in Pure python.

If I understand you, you suggest using my existing DetailView url which shows
the detailed Post, but create a view which selects a random pk.
I thought of this but I don’t know how to go about creeating a view that
selects a random pk, then applies to the existing urlpattern.

What you need is actually very simple. Create a 'random_post' URL, which points
to a view doing the shuffle logic and returns a redirect to the proper page,
say '/post/$id', then make that a valid URL and use a DetailView.

Something like this:

That is returning a string expression for your model. I will explain with
an example.
Consider you were to pull the list of authors in one of your template in a

Actually, using order_by('?') is the worst thing possible, especially in a
largish db in production.
Why?
That query generated is SELECT FROM WHERE ORDER BY RAND()
LIMIT N
where the random function is executed for every row in the result set which
is ordered by the generated va
You will just match that to /
The ?page=1 you will deal with in the view you point / to.
In you view you retrive the page value from the request object
Somthing like
page = request.GET.get('order', 'name')

Would give you the page number, and default to 1 if nothing was passed.

I'm trying to build a small website, using django, that stores network
performance data. The user will be able to use filters to retrieve the
exact data he/she wants and then have the option to graph that data. I'm
using django-pandas to convert filtered queryset to a dataframe and from
there
def random_post(request):
posts_ids = Post.objects.all().values_list("id", flat=True)
random_obj = Post.objects.get(id=random.choice(posts_ids))

return render(request, 'blog/random_post.html', context)

Hi! This may be better suited for the django-pandas community, as it

I am trying to process some text files and feed the result directly into a
django model using create(). As so often seems to happen with me, this
turns out to not be as simple as I thought it would be. Specifically, I
can’t seem to get any data into ‘clock’, the time field in my model. When I

Agreed. Blocking users from accessing the site seems counterproductive.
Just do a feature detection and raise an alert warning if css-grid.
Modernizr will let you do this easily

Hi.
__within is probably correct lookup.
You can find all lookups at:
