Hi Ben, thanks for your mail.
Yea, after digging into the code I see there is not currently a way to
do this, or perform queries with nested keys, such as:
/query.json?query={"type": "/type/edition", "table_of_contents":
{"pagenum": 19}}
I would like to do something like
/query.json?type=/type/edition&table_of_contents.pagenum=19
I submitted a patch, but it is a hack:
https://github.com/internetarchive/infogami/pull/2
Looking into it more I see web.py retrieves the query parameters via
'FieldStorage' from python's cgi.py, which parses the query string with
'parse_qsl' from urlparse.py. So by the time web.py gets the parameters,
they've already been decoded by 'parse_qsl', making it difficult to do
additional parsing...
But, one could monkey-patch urlparse with a custom parser -- I've been
experimenting with this just now and it seems like it could work out
alright, though it is still a bit of a hack.
Any thoughts on syntax, supposing I did try this?
multi-value:
&subjects=war,peace
&subjects=[war,peace]
&subjects=war+OR+peace
nesting:
&table_of_contents.pagenum=19 (I reckon this is the most natural
looking, but since . is unreserved it might cause trouble)
&table_of_contents:pagenum=19
&table_of_contents::pagenum=19
