Edit Question
Title
Body
I'm going through a few error scenarios, trying to understand how to handle those. In the case where there is no database connection, a Mongoose Model.find(...) call seems to hang. Below the example code. I would have assumed that the callback is invoked with an err object, but it is not. How can I prevent the model call to hang? Do I manually have to check the readyState each time I access a model? // app.js // Let's use a non-existing host so connecting fails: // (callback is invoked with err object) mongoose.connect('mongodb://localhostXXX/blog', function(err){ ... }); BlogPost = mongoose.model('BlogPost', BlogPostSchema); // api.js exports.list_posts = function(req, res) { // Ready state is '0' = disconnected (since we used a wrong hostname) console.log('DB ready state: ' + BlogPost.db.readyState); // This will not invoke the callback: BlogPost.find(function(err, threads) { // Never called... }); }
