Description

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.
