Enter multiline filter function in source editor?
Hello,
In Fulton admin interface, you click source editor to edit directly...
I was trying to add one filter function like this..
"filters": {
"by_country": "function(doc ,req) { blahblah...... } "
}
The thing is that when I tried to enter the function with new line for more readable format,
(ex, function (doc,req) {
blah1
blah2
})
I saw validation error like saying..
"JSON.parse: bad control character in string literal at line 6 column 23 of the JSON data"...
1. I don't think I have to enter the function in one line...is there any escaped character I need to enter to format the function?
2. I know I can query the filter over http rest api, but is there any way I can run the filter function in fulton web interface?
Thanks,

No. Futon tries to work with as with JSON values. JSON strings lacks
multiline support.

Yes, that's absolutely true that I can provide my own _id ..then it will return conflict staust if it is duplicated. HOWEVER, what I was asking, "Other than _id"..

You could assign your own ids that describe the contents of the document. ie. POST your own '_id' field when creating the document. If the '_id' exists it will fail with an update conflict - stopping duplicate data from being inserted.

No, that's not possible. Validate doc update function only operates
with document's new version candidate and the "old", current one. It
cannot not access to others since this will slow down whole the
process and break eventual consistency. You should run this check
outside CouchDB in your client code before PUT the document.

Hello,
Since CouchDB provides validate_doc_update, I thought that I might be able to provide some to check duplication here..
like...
function(newDoc,oldDoc,userCtx) {
if(newDoc.type == "myCustomType") {
// here..something like..
// check newDoc against the existing documents of "myCustomType" to see whether there was already same data or not..
// for example,
// getExistingDocumentsByType("myCustomType").forEach(function(doc) {
// if(newDoc.mydata == doc.mydata) {
// ///Boom..throw error..
// }
// });
//
Is this something possible? Well..obviously there is no provided getExistingDocumentsByType function from couchdb.....just was trying to show what I was trying to achieve...
So ultimately, my question is that..is there any way I can somehow access the existing documents from validate_doc_update function?
Thanks,
Re: Anyway I can define my javascript function that can be
accessed in every design?
Posted by James Dingwall <ja...@zynstra.com>.
> My question is ..is there any way I can define some common function
that this can be accessed from every design doc? Thanks,
Short answer: no.
Longer answer: Yes, I manage my design docs using couchapp and symlink
common code between design documents in to views/lib/commoncode.js which
can then be require()d in the view function. i.e. something like:
views/lib/commoncode.js:
function api() {
var _afunc = function(a1, a2) {
...
};
var _api = {
afunc: _afunc
};
return(_api);
}
exports.cc = api();
// views/lib/commoncode.js
My view map.js:
function(doc) {
var cc = require('views/lib/commoncode').cc;
if(cc.afunc(doc, 'banana') === true) {
emit(doc._id);
}
}
Notes:
- you cannot require() in the reduce function but there is an open bug
for that feature.
- shared code for views *must* be kept under the views key in the
design document. The content of the views key is hashed to determine if
view indexes need to be rebuilt after a design document update. There
is no problem with other design doc operations doing a require() of code
from views/lib (show/list/update etc).

James
Anyway I can define my javascript function that can be accessed in
every design?
Posted by TAE JIN KIM <sn...@hotmail.com>.
Hello,
In mydesign1/firstview,
my function has been defiend like..
function mycommon() {
..
...
}
in mydesigin1/secondview
I am able to use the mycommon javascript function that has been defined in firstview of same design doc, which is mydesign1.
Say I created another design doc, which is mydesign2..
in mydesign2/firstview, I can't access the mycommon function because this is different design doc...
My question is ..is there any way I can define some common function that this can be accessed from every design doc?
Thanks,

Futon isn't suitable for design function edition (except views). Try
erica: it has nice web editor and is made specially to simplify work
on design documents.
