Question

我有一个猫鼬模型：

const mongoose = require('mongoose');

const id = mongoose.Schema.Types.ObjectId;

const templateSchema = mongoose.Schema({
    _id: id,
    heading: {
        type: String,
        required: true
    },
    content: {
        type: String,
        required: true
    }
});


module.exports = mongoose.model("template", templateSchema);

在我的应用程序中，我具有基于角色的其余API控件。管理员可以创建这些模板，客户端/用户将在前端进一步使用这些模板。但是对于初始化，我需要通过admin在数据库中创建3-4个默认模板。

这些默认模板将在应用程序启动后立即从数据库本身呈现/获取。管理员将使用适当的端点进一步创建更多新模板，这些模板将被推送到默认模板的现有数据中。

我读过有关在猫鼬模型中使用static methods的信息，但不确定这样做是否正确。

尽管我尝试了以下JS方法，但是没有用。

const mongoose = require("mongoose");

const id = mongoose.Schema.Types.ObjectId;

const templateSchema = mongoose.Schema({
  _id: id,
  heading: {
    type: String,
    // required: true,
  },
  content: {
    type: String,
    // required: true,
  },
});

module.exports = mongoose.model("template", templateSchema);

// let Template = mongoose.model("template", templateSchema);

let defaultTemplates = [
  {
    heading: "CONNECTION REQUEST",
    content:
      "<div><p>Dear Mark,</p><p>It was great meeting you at the ESRI conference in San Diego last month.The mapping and charting work you do for airports sound fascinating.I'd definitely like to stay up-to-date with your career.</p><p>Thank you,</p><p>Lindsey</p></div>",
  },
  {
    heading: "MESSAGE AFTER CONNECTION ACCEPTED",
    content:
      "<div><p>Dear Mark,</p><p>It was great meeting you at the ESRI conference in San Diego last month.The mapping and charting work you do for airports sound fascinating.I'd definitely like to stay up-to-date with your career.</p><p>Thank you,</p><p>Lindsey</p></div>",
  },
  {
    heading: "INTRESTED MESSAGE",
    content:
      "<div><p>Dear Mark,</p><p>It was great meeting you at the ESRI conference in San Diego last month.The mapping and charting work you do for airports sound fascinating.I'd definitely like to stay up-to-date with your career.</p><p>Thank you,</p><p>Lindsey</p></div>",
  },
];

let new_details = [];
defaultTemplates.forEach((temp) => {
  temp._id = new mongoose.Types.ObjectId();
  new_details.push(temp);
});


templateSchema.statics.saveTemplate = function(new_details, callback){
    var template = new this(new_details);
    template.save(callback);
};

它不会将模板保存到数据库，并一次又一次出现以下错误：

Template.saveTemplate(function(result) {
         ^

TypeError: Template.saveTemplate is not a function

请帮助我解决这个问题。
