Given that your choices are linear starting with one, you can do
something like
AGE_CHOICES[int(cd['age'])-1]
For the more general case you'd want to create a dict() to do the
mapping for you, but you need to insure the key is of the same
type (int vs. string). I have the following pattern in my code
quite a bit:
FOO_A = 'a'
FOO_B = 'b'
FOO_C = 'c'
FOO_CHOICES = {
FOO_A: 'This is A",
FOO_B: 'This is B's description",
FOO_C: 'This is my C",
}
class MyModel(Model):
foo = CharField(..., choices = FOO_CHOICES.items())
:
:
foo = my_form.cleaned_data['foo']
my_foo_desc = FOO_CHOICES.[foo]
If order matters, you can use
choices=sorted(FOO_CHOICES.items())
or
choices=sorted(FOO_CHOICES.items(), key=lambda x:x[1])
as your "choices" clause to sort them (the first by key, the
second by value), as dicts aren't guaranteed to be ordered.
Hope this helps,
