Django tag cloud

[Alessandro Ronchi]

I have a model with with a variable number of objects.

I want to make a tag cloud with font-size to be a proportion of
objects.count() (wich goes from 1 to 150 ).

Obviously I can't use that number in font-size (150pt is too big) and
I have to make a proportion (150 -> 20pt, 1 -> 5pt, 50 ~>10pt and so
on).

How can I accomplish that?

I used this approach, was explained on "Learning website development with Django book", give a look there:

style.css file:

.tag-cloud-0 { font-size: 100%; } 

.tag-cloud-1 { font-size: 120%; } 

.tag-cloud-2 { font-size: 140%; } 

.tag-cloud-3 { font-size: 160%; } 

.tag-cloud-4 { font-size: 180%; } 

.tag-cloud-5 { font-size: 200%; }

And generated the tag number dynamically counting the objects that has that tag.

And generated the tag number dynamically counting the objects that has that tag.

But in that way I must add some code to the model, wjere I can write exactly the font-size.
I need something similar to widthratio but with a minimum value (or maybe there is a way to make the littler sets not to 0 font-size).

What you need is called data normalization - fitting data to a desired scale - in statistics and analysis.

Here's a general page about normalization:

I'd imagine that there's a Python library or module that will do this for you, but it's not hard to write your own.

I've done a simple custom template tag to have my cloud working :)
