Question

I’m trying to update and array passing a json object or variables and build the json in the function. Which is the best way to do it?

For example, the function which I use to send variables and build the json:

function(doc,req){ 
var name = req.query.name; 
var number = req.query.number;
var channel = {"name":"" , "number" : ""};
channel.name = name;
channel.number = number;
doc.channels.push(channel); 
return[doc, channel + ' added'];}

curl -X PUT https://server/db/_design/doc/_update/addChannel/channels?name=myChannel&number=23

But what I got is just this in the array:

{
    "name": "myChannel"
}

Why the second variable is not there?

Is it possible to pass a json object in the url like : channels?json={}… ??

Thanks

I suspect you forgot to enclose the url in single quotes. The presence of the & indicates to your shell that it should run the command in the background (and the ‘number=23’ part is simply ignored).

try;

curl -X PUT 'https://server/db/_design/doc/_update/addChannel/channels?name=myChannel&number=23'

and I suspect it will work.

I’ll also note that the function could be written more simply as;

function(doc,req) {
  doc.channels.push({"name":req.query.name, "number": parseInt(req.query.number)});
  return [doc, channel + ' added'];
}

Note that the “23” will be passed as a string, so I added a parseInt call also.
