Question

我正在尝试为“ comment”类型创建一个Mongoose模式，该模式在“ text”，“ time”，“ user”字段内，但也包含“ comments”数组，这意味着该评论的答案。如何指定注释中该字段的数组类型也是注释。我为您留下了一些我想做的代码。替代方案也很受欢迎（除了将答案的ID存储在数组中之外，这是一个很粗糙的解决方案）。非常感谢

const CommentSchema = new Schema({
    text: { type: String, required: false },
    timestamp: { type: Date, required: true, default: Date.now },
    user: { type: String, required: true },
    answer: [ CommentSchema.schema ],
    liked: [ String ]
});

Answer 1

您可以试试吗？我认为应该可以

const CommentSchema = new Schema({
    text: { type: String, required: false },
    timestamp: { type: Date, required: true, default: Date.now },
    user: { type: String, required: true },
    answer: {
      type: [CommentSchema],
      default: []
    },
    liked: [ String ]
});

Answer 2

您尝试这种打击模式（或）并阅读docs。

const answersCommentsSchema = new Schema({
 text: { type: String, default : null },
    user: { type: String, required: true },
},{timestamps : true});

const CommentSchema = new Schema({
    text: { type: String, default : null },
    user: { type: String, required: true },
    answer: [answersCommentsSchema],
    liked: {type : Array, default:[]}
},{timestamps : true});
