建立Bootcamp Model

完成資料庫的設置後，接著我們就能為第一筆資料（Bootcamp）訂定Schema！
首先，建立一個models資料夾，並在裡面創建Bootcamp.js file

const mongoose = require('mongoose');

const BootcampSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'Please add a name'],
    unique: true,
    trim: true,
    maxlength: [50, 'Name cannot be more than 50 characters']
  },
  slug: String,
  description: {
    type: String,
    required: [true, 'Please add a description'],
    maxlength: [500, 'Description cannot be more than 500 characters']
  },
  careers: {
    type: [String],
    required: true,
    enum: [
      'Web Development',
      'Mobile Development',
      'UI/UX',
      'Data Science',
      'Business',
      'Other'
    ]
  },
  address: {
    type: String,
    required: [true, 'Please add an address']
  },
  createdAt: {
    type: Date,
    default: Date.now
  }
 
module.exports = mongoose.model('Bootcamp', BootcampSchema);

CRUD功能

為了能對Bootcamp的資料進行操作，我們要在'controllers/bootcamps'寫入與Bootcamp model互動的邏輯
Create:

const bootcamp = await Bootcamp.create(req.body);

Read Specific Bootcamp:

const bootcamp = await Bootcamp.findById(req.params.id);

Read All Bootcamps:

const bootcamps = await Bootcamp.find();

Update Bootcamp:

const bootcamp = await Bootcamp.findByIdAndUpdate(req.params.id, req.body, {
  new: true,
  runValidators: true
});

Delete Bootcamp:

const bootcamp = await Bootcamp.findByIdAndDelete(req.params.id);
