Subject [Erlang] Logging
Date Thu, 06 Oct 2011 22:34:18 GMT
Hi,

Is there a way to log from within an Erlang view? I am trying to reproduce
the unit test for the list function and am getting an error. I'd like to log
the value of "Val" so I can understand the underlying data structure. I
tried error_logger:info_report(Val). Thanks!

Output from view:

{"total_rows": 1,"offset": 0,"rows": [{"id": "1","key": 1,"value": "str1"}]}

List code:

fun(Head, {Req}) ->
Send(<<"head">>),
Fun = fun({Row}, _) ->
Val = couch_util:get_value(<<"value">>, Row, -1),
Send(list_to_binary(integer_to_list(Val))),
{ok, nil}
end,
{ok, _} = FoldRows(Fun, nil),
<<"tail">>
end.

Error:
