I'd say this is outside the scope of add_query_params().
As for the duplicate handling, I've implemented a threefold strategy that
should address all use cases raised before:
def add_query_params(*args, **kwargs):
"""
add_query_parms(url, [allow_dups, [args_dict, [separator]]], **kwargs)
Appends query parameters to an URL and returns the result.
:param url: the URL to update, a string.
:param allow_dups: if
* True: plainly append new parameters, allowing all duplicates
(default),
* False: disallow duplicates in values and regroup keys so that
different values for the same key are adjacent,
* None: disallow duplicates in keys -- each key can have a single
value and later values override the value (like dict.update()).
:param args_dict: optional dictionary of parameters, default is {}.
:param separator: either ';' or '&', the separator between key-value
pairs, default is '&'.
:param kwargs: parameters as keyword arguments.
:return: original URL with updated query parameters or the original URL
unchanged if no parameters given.
"""
The commit is
http://github.com/mrts/qparams/blob/b9bdbec46bf919d142ff63e6b2b822b5d57b6f89/qparams.py
extensive description of the behaviour is in the doctests.
