Assignee: Ryan Ramage
Suggested alternate method to solve. Feature backlogged for future futon work.
> Transform all documents at once
> -------------------------------
>
> Key: COUCHDB-1612
> URL: https://issues.apache.org/jira/browse/COUCHDB-1612
> Project: CouchDB
> Issue Type: Wish
> Components: Futon
> Reporter: jean honlet
> Assignee: Ryan Ramage
> Priority: Minor
>
> Sometimes, I would like to modify all documents at once...
> I use this function (jQuery, jquery.couchdb and Underscore necessary):
> function actionAllTransform(transform, commit) {
> // First get all documents:
> jQuery.couch.db(dbname).allDocs({
> include_docs: true,
> success: function(data) {
> data = _.map(data.rows, function(v) {
> return v.doc;
> });
> // Remove the design documents
> data = _.filter(data, function(doc) { return (doc._id.substring(0,8) != "_design/"); });
> // transform each document by a "transform" function
> data = _.map(data, transform);
> // If the function gave back null value, filter them out (they are considered as not modified)
> data = _.filter(data, function(doc) { return (doc != null); });
> if (data.length == 0) {
> // no record left, nothing to do...
> return 0;
> }
> var bulk = { all_or_nothing: true, docs: data };
> // Check the result
> console.log(bulk);
> if (typeof(commit) == 'undefined')
> return
> // If commit, save the bulk in the db
> if (commit) {
> jQuery.couch.db(dbname).bulkSave(bulk, {
> success: function() {
> // youpee, it worked
> }
> });
> }
> }
> });
> };
> As far as I understand, the question is to be able to put that function in the futon interface... and render results in the same styleguide than the other panels.
