[jira] [Created] (COUCHDB-1300) Array.prototype isn't getting set.
Array.prototype isn't getting set.
----------------------------------
Key: COUCHDB-1300
URL: https://issues.apache.org/jira/browse/COUCHDB-1300
Project: CouchDB
Issue Type: Bug
Components: JavaScript View Server
Affects Versions: 1.1
Environment: Ubuntu 11.04, node.couchapp, commonJS
Reporter: paul iannazzo
##file helpers.js in views/lib/common
const _ = require("views/lib/underscore");
Array.prototype.compact = function(){return _.compact(this);};
Array.prototype.flatten = function(){return _.flatten(this);};
//this function is called from views.someName.map

the first logs show that doc.store.taxes is an array, why do i need to use Array() on it in order to use the prototype functions?

paul iannazzo commented on COUCHDB-1300:
----------------------------------------
I found a workaround (i guess solution in this case) to my problem.
instead of using array prototypes i can get the same functionality via monads (specifically the underscore library).
anyway, i found this issue very confusing.
thank you for your quick response.

[jira] [Commented] (COUCHDB-1300) Array.prototype isn't working

Filipe Manana commented on COUCHDB-1300:
----------------------------------------
Hi, there's a reason for that, and it's exactly the same reason why "foo instanceof Array" fails when foo is created in a browser iframe and the previous expression evaluated in another iframe which is accessing that array.
For couch, the user document is json decoded in one javascript context and the map function ran against the document is executed in another context (a sandbox). Each context has its own Array constructor.
