An infact, I'd say that it's bad design to make your template author
know about .views. Instead, you should just be passing a list from the
view, not a dictionary, unless you actually need a dictionary, ie:
return render_to_response ('myapp/detail.html', { 'key1': value1,
'key2': value2, 'campaigns':dict1.values()})
Then, in your template, you can do
{% for item in campaigns %}
{{item.id}}
{% endfor %}
Try playing around in the Python interpreter, to see the differences.
In [4]: x = {"a":1, "b":2, "c":3}
In [5]: x.keys()
Out[5]: ['a', 'c', 'b']
In [6]: x.items()
Out[6]: [('a', 1), ('c', 3), ('b', 2)]
In [7]: x.values()
Out[7]: [1, 3, 2]
In [8]: for each in x:
...: print each
...:
...:
a
c
b
In [9]: for each in x:
...: print x[each]
...:
...:
1

The Python interpreter is one of the best weapons in any Pythonistas
arsenal, learn to make it your best friend when coding.
