Hi all,
With 1.1 out of the door (great!), here's a thought for 1.2...
I often end up writing the same couple of template tags and filters. I
think some of these are general enough and useful enough that they
should be considered for basic Django 1.2, even though they're fairly
easy to write as add-ons. Here is my wishlist - please feel free to
comment on any others that you would like to see and on any of mine
where I've missed an obvious way to use the existing tags.
Filter: get
The built in dot (.) operator is great for accessing dictionary
lookup, attribute lookup, etc. However, it doesn't work when the
attribute/dictionary element is also a variable. I use a 'get' filter
with code like:
{% for k in keys %}
Value for {{ k }} is {{ d|get:k }}<br/>
{% endfor %}
where I'd like to just write d.k
I couldn't find another way, and often end up writing this operator,
so think that it or an equivalent mechanism should be built in.
Tag: ifstartswith
I find this very useful in writing menus, navigation bars, etc. since
I'm often checking whether the URL is within a given subdirectory.
Filters: sort and sortreversed
We have dictsort and dictsortreversed already, but what about sorting
simple lists? e.g.
{% for i in i_list|sortreversed %}
Yes, I could usually sort the list before passing it into the
template, but it's nice to be able to do it in the template at well!
Cheers,
Richard.
