Question

我是node和mongodb的新手，当我尝试使用router.delete方法删除它时，创建了一个嵌入式/嵌套文档，它导致以下错误：TypeError：将圆形结构转换为JSON.stringify的JSON （）。如何解决此问题并删除我的文档？

我尝试了mongodb方法的findByIdAndRemove和findByIdAndDelete。

**Article Schema**
const articleSchema = new mongoose.Schema({
    articleName: {
        type: String
    },
    author: [{
        type: mongoose.Schema.Types.ObjectId,
        ref: 'Author'
    }],
    comments: [commentSchema]
})

const Article = mongoose.model('Article', articleSchema)

**Route Delete Method**
router.delete('/:id', async (req, res) => {
    const article = Article.findByIdAndDelete(req.params.id)
    res.send(article)
})

**Comment Schema**
const commentSchema = new mongoose.Schema({
    articles: {
        type: new mongoose.Schema({
            articleName: {
                type: String
            },
            author: [{
                type: mongoose.Schema.Types.ObjectId,
                ref: 'Author'
            }],
        })
    },
    users: {
        type: new  mongoose.Schema({
            name: String
        })
    },
    comment: String
})

**User Schema**
const userSchema = new mongoose.Schema({name: String, email: String})

UnhandledPromiseRejectionWarning：TypeError：转换循环structure to JSON at JSON.stringify (<anonymous>)

您是否错过了await

**Route Delete Method**
router.delete('/:id', async (req, res) => {
    const article = await Article.findByIdAndDelete(req.params.id)
    res.send(article)
})

无法使用DELETE方法删除mongodb中的文档
