I'm new to this as well. Though to control access to a document, there is a
sample project to refer to: https://github.com/couchbaselabs/ToDoLite-iOS.
It give each doc a property: memebers, it is an array where all users that
has access would be set in this array.
Then each time sync function is processing the doc, channel access is given
to these user within the array. The code below.
if (Array.isArray(doc.members)) {
var memberNames = [];
for (var i = doc.members.length - 1; i >= 0; i--) {
memberNames.push(doc.members[i].substring(doc.members[i].indexOf(":"
)+1))
};
access(memberNames, "list-"+doc._id); //"list-"+doc._id is the
channel name
}
I've not yet been using roles yet, so lets count on the others.
