You could do it that way, but no, that is not what I meant.

You have an external library that is producing data in one format. You
want to use that library, without changing the library itself, in
another library (django) that expects a different format.

The interface for inserting information into a Form is the QueryDict.
Start with the QueryDict that django decodes from the request, and
rewrite the key names so that they now match up with the format that
Django allows for forms (and matching your class).

The alternative way is dynamically producing the fields so that you
can create fields with unpythonic names. Personally, I think it is
cleaner to transform the data to match your API than munge the API to
match your data.

Cheers

Tom
