Hi,
I made great progress converting Javascript shows to Erlang. I need some
help with lists in Erlang. I have a JSON document that has pointers to other
documents (with include_docs=true). Within the list, I construct a new JSON
document that aggregates information I pulled from the documents that were
referenced. Below you'll find the Javascript implementation. I am having
trouble reproducing this in Erlang.
This is what I have in Javascript:
function(head, req) {
start({
"headers" : {
"Content-Type" : "text/plain"
}
});
var page = [];
while( row = getRow()) {
var module = row.value.module;
var desc = row.doc.desc;
var title = row.doc.title;
var module = {
"module" : module,
"desc" : desc,
"title" : title
};
page.push(module);
}
send(JSON.stringify(page));
}
I am starting from what's in the unit test:
%% Page generator (from Futon unit test)
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.
In a show I was able to construct a new JSON document and then return it
with:
{[{<<"code">>, 200}, {<<"headers">>, {[]}}, {<<"json">>, MyDoc}]}
How can I do something similar where I iterate through the rows, take some
data from each row and then send the result as a single JSON document?
Thank you!
Thomas
