How to insert in Collection within a Fiber ?

[Arthur Battut]

Hello,

I want to insert in the Tweets collection every tweets from the stream made with Twit (npm module), inside a method.

Here is my code:

    stream: function(hashtag) {
        //Création du stream
        stream = T.stream('statuses/filter', { track: hashtag });
        var currentHashtag = hashtag;

        // Lance le stream
        stream.on('tweet', function (tweet) {
             var userName = tweet.user.screen_name;
                var userTweet = tweet.text;
                var tweetDate = tweet.created_at;
                var profileImg = tweet.user.profile_image_url;

            console.log(userName+" a tweeté: "+userTweet+" le: "+tweetDate);
            console.log("=======================");

            Tweets.insert({user: userName, tweet: userTweet, picture: profileImg, date: tweetDate, hashtag: currentHashtag}, function(error) {
                if(error)
                    console.log(error);
            });
        });
    }

And here is my error message:
[Error: Meteor code must always run within a Fiber. Try wrapping callbacks that you pass to non-Meteor Libraries with Meteor.bindEnvironment. ]


I've tried different solutions in vain, like wrap the Collection insertion in a Fiber(), and I try to use a Meteor.bindEnvironment, but never understand how to properly use it.

Can you help me ?

stream.on('tweet', Meteor.bindEnvironment(function(tweet) {

   ...

}));

Thanks for your answer, I don't have errors now (wich is great), but when I go into meteor mongo and make db.Tweets.find().count(), it returns 0. Do you know why ?

[Gadi Cohen]

Mmm, no :)  Are the tweets arriving and showing up in the server console log?  Is there a 2nd result argument to the Insert callback?

[Gadi Cohen]

can you show me the line where you instantiate the Tweets Collection?
