Reverse Populate

In Model (Options)

toJSON: {virtuals: true},
toObject: {virtuals: true}

BootcampSchema.virtual('courses', {
  ref: 'Course',
  localField: '_id',
  foreignField: 'bootcamp',
  justOne: false
});

In Controller

query = Bootcamp.find(JSON.parse(queryString)).populate('courses');

Course Being Removed From Bootcamp

BootcampSchema.pre('remove', async function (next) {
    console.log(`Course being removed from bootcamp: ${this._id}`);
    await this.model('Course').deleteMany({bootcamp: this._id});
    next();
})

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

Calculating The Average CourseCost

CourseSchema.statics.getAverageCost = async function (bootcampId) {
    const obj = await this.aggregate([
        {
            $match: {bootcamp: bootcampId}
        },
        {
            $group: {
                _id: '$bootcamp',
                averageCost: {$avg: '$tuition'}
            }
        }
    ]);
    try {
        await this.model('Bootcamp').findByIdAndUpdate(bootcampId, {
            averageCost: Math.ceil(obj[0].averageCost / 10) * 10
        })
    } catch (errors) {
        console.log(errors);
    }
}

//Call AverageCost After Add Course **********************
CourseSchema.post('save', function () {
    this.constructor.getAverageCost(this.bootcamp);
});

//Call AverageCost Before Remove Course ******************
CourseSchema.pre('remove', function () {
    this.constructor.getAverageCost(this.bootcamp);
});

Encrypt Password Using bcryptjs

UserSchema.pre('save', async function (next) {
   if (!this.isModified('password')) {
          next();
      }
   const salt = await bcrypt.genSalt(10);
   this.password = await bcrypt.hash(this.password, salt);
});

get Signed JWT

UserSchema.methods.getSignedJwtToken = function () {
    return jwt.sign({id: this._id}, process.env.JWT_SECRET, {
        expiresIn: process.env.JWT_EXPIRE
    });
};

Match User Entered Password to Hashed Password

UserSchema.methods.matchPassword = async function (enteredPassword) {
    return await bcrypt.compare(enteredPassword, this.password);
};

Grand Access to Specific Roles

exports.authorize = (...roles) => {
    return (req, res, next) => {
        if (!roles.includes(req.user.role)) {
            return next(new ErrorResponse(`User Role ${req.user.role} is Not Authorize to access this route`, 403));
        }
        next();
    };
};

Bootcamp User Relationship

  req.body.user = req.user.id;
  
  const publishedBootcamp = await Bootcamp.findOne({user: req.user.id});
  
  if (publishedBootcamp && req.user.role !== 'admin') {
      return next(new ErrorResponse(`The User with ${req.user.id} Already Published a Bootcamp`, 400));
  }

Make Sure User Is Bootcamp Owner

if (bootcamp.user.toString() !== req.user.id && req.user.role !== 'admin') {
    return next(new ErrorResponse(`User ${req.user.id} Is Not Authorized to The Bootcamp`, 401));
}

Generate And Hash Password Token

UserSchema.methods.getResetPasswordToken = function () {
    const resetToken = crypto.randomBytes(20).toString('hex');
    this.resetPasswordToken = crypto
        .createHash('sha256')
        .update(resetToken)
        .digest('hex');
        
    this.resetPasswordExpire = Date.now() + 10 * 60 * 1000;
    return resetToken;
};

Prevent User From Submitting More Than 1 Review Per Bootcamp

ReviewSchema.index({bootcamp: 1, user: 1}, {unique: true});
