アプリケーションでこのコードを試すと:
アプリ/モデル/Post.coffee
mongoose = require "mongoose"
CommentModel = require "./Comment"
Comment = CommentModel.Schema
Schema = mongoose.Schema
Post = new Schema {
title: String,
slug: {type: String, index: { unique: true, dropDubs: true }},
content: String,
author: String,
tags: [String],
comments: [Comment],
created: { type: Date, default: Date.now }
}
Post.statics.findBySlug = (slug, cb) ->
this.model("Post").findOne({ slug: slug }, cb)
PostModel = mongoose.model "Post", Post
module.exports = PostModel
アプリ/モデル/Comment.coffee
mongoose = require("mongoose")
Schema = mongoose.Schema
Comment = new Schema {
author: String,
content: String,
approved: Boolean,
created: { type: Date, default: Date.now }
}
CommentModel = mongoose.model "Comment", Comment
module.exports = CommentModel
app/controllers/PostsController.coffee (メソッドは 1 つだけ)
commentDestroy: (req, res, next) ->
Post.findBySlug req.params.slug, (err, doc) ->
if (err)
return next err
if doc == null
res.send 404
return
doc.comments.id(req.params.comment).remove()
doc.save (err) ->
if err
next err
res.json doc
エラーで終了します:
TypeError: Object [object Object],[object Object],[object Object],[object Object],[object Object] has no method 'id'

私はすでに私の問題の解決策を見つけようとしましたが、これだけを見つけて、スキーマが正しい順序であると思います( by require )。
ご回答ありがとうございます。
