我有一个同时拥有hometeam和awayteam变量的团队,我现在有下面的代码来显示每场比赛的家庭团队的名称,我将如何改变这一点,以便我显示家庭团队和远程团队每个匹配,使它看起来像下面这样:
[
"Team 1", "Team 2",
"Team 3", "Team 4"
]
其中1/2队在一场比赛中,而3/4队在另一场比赛中。
app.get('/homeTeamNames', function(req, res) {
util.log('Serving request for url [GET] ' + req.route.path);
Match.find({}, {'hometeam': 1}).populate('hometeam', {name: 1}).exec(function(err, teams) {
var homeNames = [];
for(var i = 0; i < teams.length; i++) {
homeNames.push(teams[i].hometeam.name);
}
res.send(homeNames);
});
});
