I'm trying to understand how dictionary lookups work in templates. To
that end I'm passing in a dictionary of lists like this,
allyears = {"2002":["a","b","c"], "2003":["a","b","c"]}
return render_to_response('press/inthepress_index',
"allyears":allyears,)
into the template, ie in the webpage, show all thingies for each year.
I have a corresponding fragment like this in a template:
[[[
{% for yearkey in allyears.keys %}
<h3>{{yearkey}}</h3>
<ul>
{% for entry in allyears.yearkey %}
<li>{{entry}}</li>
{% endfor %}
</ul>
{% endfor %}
]]]
which produces this:
[[[
2002
2003
]]]
ie the lookup allyears.yearkey is not returning the list value even
though the yearkey is taken directly from the dict's keys. I think this
is expected behaviour as the template engine will be looking for a
field called "yearkey" on the allyears dict rather than evalauting it
first *.
If so, is there an idiom for generically looping over dictionaries or
nested lists in templates?
cheers

* An aside. If instead of using a key on the allyears dict, I use
literals, ie like this:
[[[
<h3>2003</h3>
<ul>
{% for entry in allyears.2003 %}
<li>{{entry}}</li>
{% endfor %}
</ul>
<h3>2002</h3>
<ul>
{% for entry in allyears.2002 %}
<li>{{entry}}</li>
{% endfor %}
</ul>
]]]
I get what I'd expect
[[[
2003
* a
* b
* c
2002
* a
* b
* c
]]]
