I have three button to show different type of information
Status: filtering ONLY news OR events works. But how to see both?
My issue is to write a mongodb query in combination with a session variable. Commented out lines show a failed approach. In my failed approach I tried to put more into the session value (i.e., adding the word type). However, this broke all queries.
My js-file:
Template.newsEvents.helpers({
newsEventsData: function () {
// return NewsEvents.find({Session.get('newsEventsView')}, {sort: {createdAt: -1}, limit: 3});
return NewsEvents.find({type: Session.get('newsEventsView')}, {sort: {createdAt: -1}, limit: 3});
}
});
Template.newsEvents.events({
'click #js-seeAll': function (evt, tpl) {
//Session.set('newsEventsView', '$or: [ { type: "news" }, { type: "event" } ]');
},
'click #js-seeNews': function (evt, tpl) {
//Session.set('newsEventsView', 'type: "news"');
Session.set('newsEventsView', 'news');
},
'click #js-seeEvents': function (evt, tpl) {
//Session.set('newsEventsView', 'type: "event"');
Session.set('newsEventsView', 'event');
}
});
My JSON file:
{
"_id" : "7sLK32LdoLv4NmtMJ",
"title" : "3rd News",
"description" : "Some News",
"type" : "news",
"createdAt" : ISODate("2016-01-18T11:23:36.412Z")
}
Any help appreciated.
Use the $in clause and use an array for your Session variable 'newsEventsView'. I personally use this to filter messages based on their type. The types of the messages are added to an array that is stored as a Session variable and then passed to the $in clause. If the user doesn't want to see a certain type, they click a button which updates the Session variable. Your code would look like this:
Template.newsEvents.events({
'click #js-seeAll': function (evt, tpl) {
Session.set('newsEventsView', [ "news", "event" ]);
}
});
Template.newsEvents.helpers({
newsEventsData: function () {
return NewsEvents.find({
type: {
$in: Session.get('newsEventsView')
},
{
sort: {
createdAt: -1
},
limit: 3
}
});
}
});
