This is the relevant part of my app.js file:
这是我的app.js文件的相关部分:
var uristring= 'mongodb://'+process.env.MONGOLAB_URI+'/images';
var theport = process.env.PORT || 5000;
var appDir = path.dirname(require.main.filename);
mongoose.connect(uristring, function(err,res){
if (err) {
console.log('ERROR connecting to: '+uristring+'. ' + err)
}
else {
console.log('Succeeded connected to: '+uristring);
}
});
var conn = mongoose.connection;
conn.on('error', console.error.bind(console, 'Database connection error, fcukkk:'));
conn.once('open', function callback() {console.log("sup stud, Database connected.")});
I am confused because there is no mention in the docs https://devcenter.heroku.com/articles/nodejs-mongoose of actually creating the database that I am trying to connect to. I assume this is something that mongoose does when you initially connect to the db.
我很困惑因为在文档https://devcenter.heroku.com/articles/nodejs-mongoose中没有提到实际创建我想要连接的数据库。我假设当你最初连接到db时,这是mongoose所做的事情。

Do you realize that you are connecting successfully at the end of the log? The first 3 times it looked for your DB at localhost:27017, but the 4th time it looked for the proper address (it seems).
您是否意识到您在日志结束时成功连接?它在localhost上寻找你的数据库的前3次:27017,但它第四次寻找正确的地址(似乎)。
