Accessing Request Parameter in Erlang?

Hi,

In rewriting a Javascript list function to Erlang, I came across the need to
retrieve parameters passed in the HTTP request. In Javascript this is done
with req.query.myparam. Is there an equivalent in Erlang? Also, is there a
place where I can find more documentation?

Thanks!

Thomas

Found it:

{Query} = couch_util:get_value(<<"query">>,Req, {[]}),
MyParam = couch_util:get_value(<<"my_param">>,Query)

Hi,

There are only records of that type (or nested records):

http://www.erlang.org/doc/reference_manual/records.html
http://www.erlang.org/doc/reference_manual/data_types.html#id72848

and nice to read from:

http://20bits.com/articles/erlang-an-introduction-to-records/

Records are more like data structures in JavaScript.

Cheers,
CGS
