Node.js-为什么此代码不起作用？

Question

I have tried this code below to do things when there isn't anything found for that user when searching the database. This is using the twitch-irc library with the twitch-irc-db module for it (Node.js).

db.where('users', {name: user.username}).then(function(result) {
    if (!result) {
        console.log('No result lad');
    }
    var cid = result.items[0].cid;
    console.log(result.items[0].cid);
    if (!cid) {
        db.insert('users', {name: user.username, keys: 0}).then(function() {
            console.log(user.username + ' is new to the stream, generating them a blank database entry.');
        });
    }
});

For some reason, none of the console.log() lines above actually work. As you can see, I have tried the method of if (!result) AND if (!cid), neither of these work.

Is it possible your query is failing for some reason and you are not tracking the error?

try to add .fail

db.where('users', {name: user.username}).then(function(result) {
    if (!result) {
        console.log('No result lad');
    }
    var cid = result.items[0].cid;
    console.log(result.items[0].cid);
    if (!cid) {
        db.insert('users', {name: user.username, keys: 0}).then(function() {
            console.log(user.username + ' is new to the stream, generating them a blank database entry.');
        });
    }
}).fail(function(err) {console.log(err)});
