Routes called twice?

[daslicht]

Hi, i have the following Route:

'/test': { 
        to:'masterDetail',
        and: function(){
           var mostRecentPost = Posts.findOne({}, { sort: { date: -1 }});

                console.log('show blog newest entry: ', mostRecentPost);  0
        }
    }

When I call it I get the following message in my console:

show blog newest entry:  undefined router.js:28
show blog newest entry:  Object {_id: "hHtwqdW69cpbmjzKR", date: 1371646889506, detailsId: "hHtwqdW69cpbmjzKR", headline: "another new"} router.js:28

Why is the Route called twice ? and why is the first 'mostRecentPost' undefined?

Because the route initially runs while the subscription is still loading from the server. Then, once the data is available, it reactively re-runs with the correct data.

so its not a good idea to query the db in my routes ?

[daslicht]

Lets say i have this route: '/blog/:_postId': as long as the client calls it with parameters anything is fine

now like to have another router which reacts to just /blog but calls automatically the most recent post So my idea was to just query the db and redirect to my '/blog/:_postId': route. Whats teh best way to solve this, please?

You need to check whether the subscription is ready (you can use the ready() method on the subscription handle).

So something like:

if (postsSub.ready()) {
  var recentPost = Posts.findOne(...);
} else {
  return 'loading';
}

thank you

[daslicht]

And postsSub would be Meteor.subscribe('postsSub'); ?

I tried it i get postsSub is undefined

[tmeasday]

Something like postsSub = Meteor.subscribe('posts');
