J.G*_*ble 1 mongoose mongodb node.js
我有一个用户模型架构、一个工作模型架构和一个评论模型架构。这些模式之间的关系是用户可以提交许多作品(如博客文章),并且可以评论/评论(我们称之为批评)其他人的文章(作品)。
因此,当用户提交评论(将其视为评论)时,这就是我的发布路线。我通过 id 找到工作,然后创建一个新的评论模型对象,并将其传递给 .create() mongoose 函数。一切似乎都很顺利,直到我上foundWork.critiques.push(createdCritique)线。控制台记录错误说:
BulkWriteError:E11000 重复键错误集合:zapper.critiques 索引:username_1 dup 键:{:空}
显然,这是说对象中有两个用户名键并且它们相互冲突,但我对此不够熟悉,无法找到问题的根源并在猫鼬模型中修复它。模型如下。如果有人可以提供帮助,那将不胜感激。
// post route for getting the review
router.post('/:id', isLoggedIn, function(req, res) {
Work.findById(req.params.id, function(err, foundWork) {
if (err) {
console.log(err);
} else {
// create a new critique
var newCritique = new Critique ({
reviewerName: {
id: req.user._id,
username: req.user.username
},
work: {
id: foundWork._id,
title: foundWork.title
},
critique : req.body.critique,
date: Date.now(),
rating: 0
});
// save new critique to db
Critique.create(newCritique, function(err, createdCritique) {
if (err) {
console.log(err)
} else {
console.log("Created critique is ");
console.log(createdCritique);
// push the new critique into array of critiques of the work
foundWork.critiques.push(createdCritique);
// save to db
foundWork.save();
}
});
}
