We have published items based on list ids , we use myLists variable to filter out the List Id, but this variable is not reactive by nature ,when we try to add the new list , then items of new list are not publishing automatically.
Meteor.publish('subscription_items', function () {
var userName = this.userId ? Meteor.users.find({ _id: this.userId }).fetch()[0].username : null;
var myLists = [];
var sharedListIDs = [];
SharedLists.find({ shared_with: userName }).forEach(function (list) {
sharedListIDs.push(list.list_id);
});
Lists.find({ $or: [{ owner: userName }, { _id: { $in: sharedListIDs } }] }).forEach(function (list) {
myLists.push(list._id);
});
return Items.find({ list_id: { $in: Lists.find({ $or: [{ owner: userName }, { _id: { $in: sharedListIDs } }] }).fetch() } });.
Can we have any way to always publish fresh data. Please help me to resolve this issue. any help/suggestion would appreciate.
As David Weldon pointed out in this answer to my similar question, what you are looking for is a reactive join. By using the package publish-with-relations, I think the publish function you want looks something like this:
Meteor.publish('subscription_items', function() {
return Meteor.publishWithRelations({
handle: this,
collection: Lists,
filter: {owner: this.userId},
mappings: [{collection: SharedLists, key: 'list_id'}]
});
});
Alternatively, as a (dirty) workaround, you could call
Meteor.subscribe('subscription_items');
everywhere where you need the collection to be republished.
